Unleash Your Imagination with Rosebud AI

Rosebud AI (rosebud.ai) is a vibe-coding tool for games. You describe the game you want, or start from a template or someone else's published game, and the AI assistant Rosie writes the code and generates art and sound. Rosebud says the output is real JavaScript built on Three.js that you can open, read and edit, and that it handles 2D, 3D and voxel games, multiplayer, and AI-driven NPCs with personalities and memory. You iterate by chat ("make the jumps floatier"), playtest in the browser and publish with one click to a shareable link. Rosebud says more than 2.5 million games have been made on the platform. It also points to web apps and interactive 3D websites as supported projects.

The same credits pay for Rosebud's standalone asset tools (formerly PixelVibe): a 2D asset generator for sprites, icons, UI and tiles (PNG, transparent where needed), a sprite sheet and animation generator (PNG sheet, JSON frame data, GIF), a 3D model generator that lets you choose Rosie, Tripo or Meshy and outputs GLB (with free rigging and animation for supported humanoids made from text), and a 360-degree skybox generator with cubemap and Roblox exports. Rosebud lists compatibility with Unity, Godot, GameMaker, Phaser, Construct, Roblox Studio, Blender and Unreal. Higher plans add code download and a Windows export you can publish on Steam. Rosebud AI, Inc. was founded in 2019, went through Y Combinator (S19) and is based in San Francisco; it also runs a Rosebud for Educators program.

Every plan runs on the same credits. Paid plans also get 10,000 daily refresh credits that reset at midnight PT and are used first, up to a limit per billing period that the page does not state.

Rosebud's rough credit costs: about 2,000 credits per edit with Rosie (the default AI), about 20,000 per edit with a premium model, 200-2,000 per image or sprite animation, about 1,000 per sound or 3D model and 2,000 per skybox. At those rates the free 8,000 weekly credits cover roughly four Rosie edits, and Indie Dev's 100,000 monthly credits cover about 50 Rosie edits or 5 premium-model edits before daily refresh credits.

Unused monthly credits on paid plans roll over once to the next month and then expire; daily refresh and weekly free credits do not stack. Credit top-ups can be bought from My Plan (prices not shown on the public page). You can cancel any time and keep your games on the Free plan. Rosebud takes no commission on game earnings. The pricing page shows monthly prices only; no annual option was listed.

What Rosebud's own pages list:

Rosebud fits beginners, hobbyists, teachers and game-jam entrants who want a playable browser game quickly without installing an engine, and coders who want AI to scaffold a Three.js project they can then edit. If you intend to sell the game, budget for at least 10x Dev ($30) for commercial rights, or Pro ($50) for code download and a Windows build. Heavy use of premium models burns credits about ten times faster than Rosie.

If you want a full, traditional engine with a visual editor and native exports, look at GDevelop. Summer Engine pitches itself as an AI game engine for shippable projects. For game art only, compare Scenario or Ludo.ai.

Independent reviews are mostly feature overviews. Summer Engine, which says up front that it builds a competing tool, calls Rosebud worth it for quick shareable browser games, prototypes, jams and classrooms, but not for shipping to Steam or serious 3D; note that Rosebud's own pricing now lists a Windows export for Steam on Pro. PinkCrow also rates it strongest for 2D prototypes, platformers, puzzles and visual novels and weaker on 3D and complex RPG systems, though it mixes in the unrelated Rosebud journaling app. Ludo.ai, another competitor, notes that a polished, shippable game still needs a human directing design and assets. Be careful with search results: several reviews confuse this Rosebud with the journaling app of the same name.
