AI Game Maker Comparison 2026: What the Tools Produce, Cost and Let You Keep

Search for an ai game maker in October 2026 and you will find roughly fifteen products that claim to turn a sentence into a playable game, and they are not the same kind of product. Some host your game on their own feed and keep the code. Some hand you a project file. Some only make art. We went through the pricing pages, terms, launch posts, funding stories and public write-ups for each of them, and this is the comparison we wanted when we started: what each tool produces, what it costs, what you get to keep, and what people say about the results.

Four kinds of AI game maker under one keyword

The phrase "ai game generator" gets used for a dozen things, so it helps to sort by what comes out the other end.

Hosted prompt-to-playable platforms. You describe a game, the service builds it and hosts it, and you share a link. Rosebud, Astrocade, Bitmagic, Upit and Websim belong here. They are fast and cheap to start with and they lock the game into their runtime to a greater or lesser degree. Astrocade and Upit add a social layer with creator payouts.

Asset and design generators. Ludo.ai, Makko and SEELE sit nearer to the art department than the programmer. They give you sprites, 3D models, audio and design documents, and sometimes a thin playable wrapper. Ludo's own roundup calls itself "the asset-and-design layer" [6], which is an honest description.

Engine-embedded assistants. Roblox's Studio Assistant, Unity AI and GDevelop's AI features work inside a real engine, so the output is a project you could ship. The cost is that you need to know what an engine is. We cover Unity and Unreal in more depth in Unity and Unreal's AI tools in 2026.

General agents and app builders. Claude, ChatGPT and Gemini will write a browser game in a chat window. Lovable, Bolt and Replit wrap the same models in a project, hosting and a billing system. None is a game tool; all of them are used for games. Our post on the best AI for coding games compares the underlying models.

A fifth category gets mistaken for a game maker and is not one. Google DeepMind's Project Genie generates short explorable worlds from text, and it appears in consumer roundups, but it has no game logic you can edit. We treat it at the end of this section, and in more detail in World Models and the Future of Game Development.

The comparison table

Prices are those on each vendor's page when we read it on 9 October 2026 unless a source says otherwise. "Not stated" means the page we could read did not say, not that the answer is no.

The table compresses a lot. The sections below give the detail we think matters.

Hosted platforms: fast, cheap and sticky

Rosebud AI

Rosebud is the most visible name in the category and has the clearest price list. According to its pricing page [1], the free tier gives 8,000 credits a week in eligible regions. The paid ladder is Indie Dev at $15 a month (100,000 credits, private projects), 10x Dev at $30 (300,000 credits, commercial rights, no Rosebud branding), Pro at $50 (1,000,000 credits, downloadable code, Windows export for Steam, managed infrastructure) and Scale at $100 (2,000,000 credits, auto-scaling hosting). A daily 10,000-credit bonus, labelled "Back to School" on the page, sits on top of each paid plan and may be temporary.

The credit costs are where the plans become concrete. The page lists roughly 2,000 credits for an edit with its default AI, about 20,000 for an edit on a premium model, 200 to 2,000 for an image or sprite animation, around 1,000 for a sound or a 3D model, and 2,000 for a 360-degree skybox. Dividing the plans by those figures gives our own estimate of how many edits each tier buys before you hit the wall.

Roughly 50 default edits a month on the $15 plan is not a lot. A game that takes 40 rounds of "make the jump higher" and "add a boss" will use most of it, and the premium model, at ten times the cost per edit, gives you five. Credits roll over once, then expire. The practical reading is that $15 is a taster, $30 is the plan that lets you sell what you make, and $50 is the plan for anyone who wants to leave.

The export story is contradictory in the public record, and worth getting right because it is the question most readers ask. Summer Engine, a competitor, published a June 2026 post saying no Rosebud tier offers Steam, desktop or mobile export [8]. Ludo's roundup says Windows .exe and Steam publishing arrived on paid tiers in May 2026 [6]. Rosebud's own pricing page lists Windows export for Steam and downloadable code at Pro and above [1]. We trust the vendor's page for what the vendor sells, with the caveat that the page also says code download is desktop only. The competitor post is either stale or wrong.

Rosebud does not name its models. Reception is thin: a review aggregator rated it 3.4 out of 5 and called it useful for prototyping rather than production games, and the product's own subreddit had a few hundred members at the time of a GummySearch snapshot [23]. We found no Reddit or Hacker News threads with substantive user verdicts. The company's own page of success stories is not independent evidence.

Astrocade

Astrocade is the one hosted platform that has published usage numbers, and they are large. Fortune reported in May 2026 that it had about 5 million monthly active users, about 140 million plays a month and more than 75,000 games from creators in 80 countries, alongside a $56 million raise (a Series A led by Sea and a Series B led by Sequoia) [2]. By October the CEO told GamesBeat that monthly players had doubled to 10 million, with 220 million sessions a month and more than 100,000 playable games [4]. Kotaku carried the same figure [3].

Two cautions. These are company numbers, and neither article verifies them independently. And "playable" is the company's word for a short game consumed in a vertical, algorithmically recommended feed, closer to a short-video app than to an indie storefront [3]. A play there might last seconds. Astrocade's earlier "20 million users" line, which circulated after the Series B, appears to count people who ever joined rather than monthly actives, so we ignore it.

Creators are paid according to how much their games are played, but neither GamesBeat nor Kotaku gives rates [3][4]. The CEO told Fortune that "our top creators are making thousands of dollars a month" [2], which is a claim about the top of a distribution, not the middle. Astrocade does not name its models; the CEO says the company trains its own on platform data [4]. We could open only the first lines of its terms of service, so we cannot tell you who owns a game made there. Cinevva's roundup describes it as locked in with no code export [7], and its terms include an arbitration clause [27].

The quality debate is public. Kotaku's report opens by calling AI-generated games "slop" and says popular titles include Minecraft clones, games using copyrighted characters and knock-offs of Roblox hits, with AI artwork [3]. Some have hundreds of thousands or millions of plays, which is the uncomfortable half of the story: the audience does not seem to mind. Sequoia's David Cahn told Fortune that "women between 20 and 40 are the best users" [2], a reminder that this audience is not the one that reads indie-dev forums.

Bitmagic, Upit and Websim

Bitmagic pitches a sentence-to-playable-3D loop in the browser with multiplayer. Its site says games are free to play, that creators "own your creations," and that a waitlist is open; it lists no pricing, no export and no models [9]. It raised a $4 million seed in 2024 led by Korea Investment Partners with Supercell among the participants [10]. Aggregators disagree on its total funding ($4.3 million versus $5.8 million), and one roundup mentions a creator-credit program we could not find on Bitmagic's own site. We would call it a project to watch rather than a tool to adopt.

Upit comes from FRVR, the casual-games company. Its App Store listing describes a no-code tool where you build from voice or text, remix existing games and enter contests with a $2,500 prize pool, with an assistant called Ava [20]. A trade newsletter reported more than 40,000 creators in beta with a global launch planned for 2026; the creator program is described as free. Upit's own homepage, as we could read it, states no pricing, ownership or model [20]. That is a gap, not a negative.

Websim is the old-timer. Its homepage describes a place to "create games and apps for free" and shows community-made games and simulators [11]. Cinevva calls it a prototyping sandbox with forkable URLs and no pricing page as of September 2026 [7]. Nothing we read describes ownership, export or long-term hosting terms, so we would not build anything you need to keep there.

The newer niche tools

Cinevva's roundup lists others we could not review in depth: Gameer (interactive fiction, locked to its runtime, free with a $1.99 Pro plan), Buildbox 4 (hyper-casual, pricing behind sign-up) and Nilo (3D assets for Roblox) [7]. Cinevva is itself one of the tools compared, and it notes that Summer Engine publishes many "best AI game maker" posts ranking Summer first. The genre of roundup is conflicted.

Asset generators

Ludo.ai is the plainest about its role. Its pricing page lists Indie at $15 a month on annual billing (3,000 credits a year, five active projects), Pro at $35 (12,000 credits a year, unlimited ideation and image generation in the web app, API and MCP access) and Studio at $300 with ten seats [5]. Monthly prices were not shown. GLB export with PBR textures is the only format the page names, and it does not address who owns the output, so the Terms of Service are where to look.

Makko launched publicly on 20 April 2026 with a free tier (150 monthly art credits and 70 weekly AI coding requests, per directory listings) and a paid tier reported near $20 a month. Its pitch is style consistency: set a visual style once and every later asset inherits it [21]. The evidence for its claims comes largely from Makko's own blog, which we treat as marketing.

SEELE claims 2D and 3D games with export to Unity packages and Three.js. Listings disagree on pricing, from a flat $36.90 to per-action charges to a $300 subscription that a June 2026 Trustpilot reviewer said was needed to sell a game, along with a refund complaint [21]. One review is an anecdote. The pricing inconsistency is the finding.

Assistants inside a real engine

Roblox Studio

Roblox announced "Studio is Going Agentic" in April 2026. The post says 44% of the top 1,000 creators used Roblox Assistant or third-party AI tools through MCP between 6 March and 7 April 2026. The Assistant gained a planning mode that reads the project, asks questions and produces an editable plan; a mesh generation tool that adds textured 3D objects; procedural models, marked "coming soon"; and a playtesting agent in beta that uses the player character as a QA bot. Studio's built-in MCP server lets outside agents such as Claude, Cursor and Codex work on a project [15]. The post does not state pricing or the language models behind the Assistant. Cube, Roblox's 3D foundation model, was released in an open version earlier.

That 44% figure is the best adoption number in the entire category, because it is measured on working developers rather than visitors. It also measures use, not satisfaction, and "AI tools" includes the autocomplete you stopped noticing. The ceiling is the platform: what you build lives on Roblox.

Unity AI

Unity AI went into open beta for Unity 6 on 4 May 2026. Credits are 1,000 for 14 days on a Personal trial and then $10 a month for 1,000, with Pro, Enterprise and Industry seats including access [17]. Unity had previewed a feature in February that would let a developer prompt casual games into existence; the shipped beta is an editor assistant that writes C# scripts, builds scenes and makes placeholder assets, not a one-prompt game generator [17]. Credit rates vary by provider and Unity has not published a per-prompt cost, so you cannot predict what a given game costs. The project is yours and WebGL export works. Our Unity and Unreal post goes through the allowances.

GDevelop

GDevelop is the cheapest route to a store-published game you own in this list. Its pricing page shows a free tier with 40 AI credits a month; Silver, Gold and Pro tiers carry 200, 1,000 and 3,000 credits a week; publishing to gd.games is unlimited on every tier; and desktop, Android and iOS builds are capped per day or month by tier. The engine is open source under the MIT license [19]. Cinevva notes that paid prices rose 20% for new subscribers on 12 January 2026 [7]. The reception inside its own community is mixed. A GDevelop forum thread about the AI prompt feature has one user complaining it makes "annoyingly unplayable platform games," and another developer said the addition made them consider abandoning the engine because players might doubt the work was theirs [24].

General agents and app builders

Claude, ChatGPT and Gemini

You can build a surprising amount of game in a chat window. Claude's Artifacts produce a single HTML and JavaScript file that renders in the conversation and can be shared by link without the viewer needing an account; third-party guides report that the free plan includes Artifacts and a Sonnet model but not Claude Code [22]. Gemini's Canvas is described in a March 2026 write-up as a workspace for apps, dashboards and games that you can edit in place and share by link [26]; Google also folded its Opal mini-app builder into Gemini in December 2025 [26]. ChatGPT's Canvas is available on the free tier, but we found only a single vendor blog on whether it runs games, and it said it does not, so treat that as unverified [22].

None of the three publishes exact message limits for free users; estimates we saw ranged from roughly 10 to 40 messages in a rolling five-hour window and were observed, not official. A game with eight rounds of iteration can burn through a free window. The output is code you own in the plainest sense: copy it into a repository and carry on. What you give up is hosting, asset generation (you get colored rectangles and emoji unless you bring art) and any structure beyond one file.

Lovable, Bolt and Replit

These are general app builders that people point at games. Lovable's pricing page gave us the structure but not the dollar amounts (the plans section did not render): a free plan with 5 daily build credits up to 30 a month, paid plans with monthly credits that expire after two months, Plan Mode at 1 credit a message and default-mode messages between 0.5 and 1.7 credits. On ownership its FAQ says "You do" own the code, subject to third-party rights in the underlying models [12]. Bolt lists Free (300,000 tokens a day, 1 million a month, Bolt branding on sites) and Pro at $25 a month with 10 million tokens and no branding, and its page does not cover export or ownership [14]. Replit's Core plan is $20 a month ($18 annually) and Pro is $100, with a free mode of up to 30 hours of chat and up to $20 or $100 toward more powerful models on the two paid plans [13]. Cinevva's roundup notes Replit does not generate sprites, music or sound, so you bring your own assets [7].

For games specifically, these tools suit 2D browser projects with web-app mechanics and hosting you do not have to think about. They are worse at the game-specific scaffolding, such as asset pipelines and input handling across platforms, than the engine assistants.

Cursor or Claude Code with Godot or Unity

Ludo's roundup recommends pairing a coding agent with an engine for anyone who wants full ownership [6]. It is the only entry in this section with no ceiling and no guard rails. It is also the one that assumes you can read the code. Our cost post estimates what a heavy agentic session costs in tokens.

Project Genie

Google DeepMind opened Project Genie to US Google AI Ultra subscribers aged 18 and over on 29 January 2026. It is built on the Genie 3 world model with Nano Banana Pro and Gemini for world sketching, and sessions are capped at 60 seconds. Google says worlds do not always look realistic and characters respond slowly [18]. One outlet put the Ultra plan at $249.99 a month with an introductory discount; The Decoder's report did not state a price. We found no mention of export. It is a research prototype for exploring a generated world, and in a game-maker comparison it is a different kind of object: there is no level you can edit, only a place you can walk around for a minute.

What the numbers say about reception

Two public datasets frame the question of whether anyone wants what these tools make.

The first is Steam. Sulka Haro's census of 53,597 releases found that 10.9% of 2024 releases carried an AI disclosure, 19.9% of 2025 releases and 30.8% of 2026 releases through July [23]. That field is a developer-ticked yes or no and Valve narrowed what must be disclosed in January 2026, so comparisons across years are approximate. We reviewed the same census in our Unity and Unreal post; its more interesting findings are that most of the growth in monthly Steam launches is AI-flagged games, and that flagged games reach a modest review threshold at roughly 55% of the non-flagged rate.

The second is the game-jam world. The press page for Vibe Jam 2026, which required at least 90% of code to be written by AI, listed 945 submitted games at the time of its release [25], which we cover in our piece on web games. A jam is where "vibe coding games" works best, because the bar is a playable toy in a week.

Against that, the developer commentary we found was skeptical. An analyst quoted by PC Guide warned that AI copycats could bury original Steam games [24]; a CD Projekt Red executive said fully AI-generated games are coming but questioned whether that is the right path [24]. We found no Hacker News Show HN threads with real discussion of any hosted game maker, and the r/gamedev results were thin, so we cannot claim to know what practicing developers think of these tools beyond those fragments. If you have used one for months, your experience is better evidence than anything we can cite.

Which one for which job

We did not test these tools, so this is advice drawn from the documents, not from builds.

A first game with no coding, for fun. Start with the free tiers of Rosebud, Astrocade or Upit, or Gemini Canvas or Claude Artifacts if you already have an account. Expect a toy. Expect to run out of credits.

A game you want to sell. Check the commercial terms before you build. On Rosebud that is $30 a month at minimum; on a free tier it is not allowed. Astrocade's creator payments exist but the terms were not readable to us. The safest route to ownership is an engine (GDevelop, Godot, Unity) with an assistant, or a coding agent producing code you hold.

A Roblox game. Use the Studio Assistant. The platform is the product.

Art and audio for a game you build elsewhere. Ludo.ai, Makko, or an image model directly; start with our art post.

A prototype to test an idea. A general agent in a chat window is faster than any of the specialized tools, and the code is yours.

What to ask before you pay

Five questions separate the products more than any feature list does.

1. Can I download the code, and on which plan? On Rosebud it is the $50 tier. On Astrocade we found no report that you can.
2. May I sell the result? Free tiers usually say no. Cinevva puts it plainly: "Free tiers usually restrict commercial rights" [7].
3. What does one change cost? Credits are not comparable across products. Rosebud's page gives roughly 2,000 credits per default edit; Lovable gives 0.5 to 1.7 credits per message; Unity gives no per-prompt figure at all.
4. What happens if the company pivots? Startups in this space change direction: Inworld, in the NPC space, retired its Character Studio (see our NPC post). A game locked to a vendor runtime goes with it.
5. Who else may use my game? Astrocade's CEO says the company trains its models on platform data [4], and Rosebud's free tier makes projects public and remixable [6]. Read the terms before you upload anything you care about.

Where this is heading

Three things look likely from the evidence, and we flag them as judgment rather than fact.

First, the hosted platforms will split. Astrocade's numbers say a social, short-form, casual product with payouts has found an audience; Rosebud's pricing says a creator-tool business selling commercial rights and Steam export is another route. They compete for the same word in search and are not the same business.

Second, the engines will absorb more of the middle. Roblox's 44% usage figure and the MCP servers in Studio and Unity mean a coding agent can drive the engine directly. That makes "no engine, no code" tools justify themselves on speed and simplicity only.

Third, quality and discoverability, not generation, will be the constraint. Haro's finding that 87% of AI-flagged Steam games are commercial non-performers [23] is the cleanest number we have. Making a game has become cheap. Making a game someone wants has not.

We publish this blog for CreateGame.ai, a pre-launch product with only a landing page and a waitlist, so it is not in the comparison and we have not ranked it.

How we reviewed this

We read vendor pricing pages (Rosebud, Ludo.ai, Lovable, Replit, Bolt, GDevelop), the Roblox newsroom post, reports of Unity AI's open beta, DeepMind's Project Genie announcement coverage, and press on Astrocade (Fortune, GamesBeat, Kotaku). We read two comparison articles by tool vendors (Ludo and Cinevva) and used them only for facts we could check elsewhere or label as theirs. We did not sign up for, pay for or test any product, and nothing here is a hands-on result.

What we could not verify: Astrocade's terms on ownership (the document did not load beyond its opening); Upit's and Bitmagic's pricing; Lovable's dollar prices (the page rendered without them); SEELE's and Makko's paid tiers (directory listings disagree); Websim's current status; Rosebud's underlying models; the free-tier message limits of Claude and ChatGPT; and every user count, which comes from the companies. Several search summaries conflicted with vendor pages, and where they did we followed the vendor page and said so. Prices change, often monthly. Check them before you subscribe.
