No surprise bills

  • Free needs no credit card.
  • Free hosted usage resets every day at 00:00 UTC.
  • Hosted usage stops at its limit. Nothing is charged past it unless you turn on on-demand usage.
  • On-demand usage is off until you turn it on, and stops at a monthly limit you set.

Bigger models use more of your plan with every message. Each plan holds enough for the models it opens, so a month of building doesn't run out in a few messages.

Every plan opens its own models and every model on the plans below it. A few of the most expensive models are on no plan: they run on your own API key.

Prices in US dollars, before tax.

Five ways to build

Every way to build starts free

Start on Flockbay’s free AI with nothing to connect. Switch to your own Claude or ChatGPT, your own agent over Godot MCP, or your own API key whenever you like, and you pay the company that runs your model, never Flockbay.

  1. Flockbay's AI, free to start

    What a new account starts on

    Type your idea and press Enter: the first message runs on Flockbay's hosted model, with nothing to connect and nothing to pay. Every account starts with free usage on it. When it is used up, Hobby keeps you building, with usage every month, or you keep going on your own Claude or ChatGPT for free.

    Free to start. More usage on Hobby.

  2. Your Claude plan

    Pick Claude in the model menu and Flockbay runs Claude Code, Anthropic's coding agent, behind its own chat, with Flockbay's tools already connected. Claude Code comes with the Windows app, and you sign in on Anthropic's own page.

    Needs Claude Pro, Max, Team or Enterprise. On Windows, macOS and Linux.

    Claude or ChatGPT with Godot
  3. Your ChatGPT plan

    Sign in with ChatGPT and the same chat runs on your ChatGPT account, through the Codex engine bundled with the app. Your browser opens on OpenAI's page.

    Any ChatGPT plan, Free included.

  4. Your own agent, over Godot MCP

    An agent you run outside the app builds the game you have open, through one MCP server, flockbay. Connectors in the app writes the setup line with your paths filled in.

    Claude Code, Cursor, Codex, Gemini CLI, Cline, Kilo Code, OpenCode, Goose, Devin Desktop, LM Studio, Ollama

    Set up Godot MCP
  5. Your own API key

    Paste an OpenAI or Anthropic key and Flockbay's chat runs on it. BYOK, with the model menu listing every model your key reaches.

    Billed by your provider, per token.

Before you sign up

No Claude or ChatGPT plan yet?

Claude Pro and Max include Claude Code, and so do Team and Enterprise; the free Claude plan does not. Every ChatGPT plan builds here, Free and Go included. You sign up on Anthropic's or OpenAI's site, then come back to Flockbay and sign in.

Art, sound and 3D

Generating art and sound

Generated images and sound come with the free AI. Flockbay builds 3D models on your computer, with no key. On your own keys, images run on a key you add, audio generation on ElevenLabs, and Tripo 3D generation on Tripo. Flockbay also builds from a library of ready-made objects, or with Godot’s own shapes.

What free covers is on its own page, and Claude or ChatGPT with Godot says how your own plan connects.

FAQ

Questions

How much does Flockbay cost?
Flockbay is free, and its hosted AI is free to start: every account starts with free usage on it. You can also build on your Claude plan (Pro or Max) or your ChatGPT account (any plan, Free included) in the app, your own agent over MCP, or your own API key, and you pay the company that runs your model, never Flockbay. Optional plans add more hosted AI and the tools to launch a game: Hobby at $20 a month, Indie Developer at $60 and Studio at $200 a month. Past a plan's monthly usage, on-demand usage keeps building, billed as you go up to a limit you set. Flockbay is free: the download, the editor, Flockbay's tools and Play. Every account starts with free usage on Flockbay's hosted AI; when it is used up, Hobby keeps you building, with usage every month, or your own Claude or ChatGPT is free. You can also build on your Claude Pro or Max plan or your ChatGPT account, on any plan, in the app, your own agent over MCP (Claude Code, Codex, Cursor), or your own OpenAI or Anthropic API key. Generated pictures and sound come with the free AI; 3D models run on your own Tripo key. Optional plans add more hosted AI: Hobby at $20 a month, Indie Developer at $60 with 3× Hobby's usage, and Studio at $200 with 10×. Past a plan's monthly usage, on-demand usage keeps building, billed as you go up to a limit you set. Each opens the hosted models of its tier, makes pictures and sound from its usage, and adds the tools to launch a game, with more of each on each plan up. There is no browser editor, no cloud building, and no team or per-seat plan.
Is Flockbay free?
Yes. Plans add more hosted AI. The app, the Godot editor, Flockbay's tools and Play cost nothing, the hosted AI is free to start, and building on your own Claude, ChatGPT, agent or API key is free. Hobby ($20 a month), Indie Developer ($60) and Studio ($200) add hosted usage, the hosted models of their tier, pictures and sound from that usage, and the tools to launch a game: Video studio, Social posts, playtest links, Steam page drafting and website publishing, with Ads from the Indie Developer plan up.
What the AI does
Flockbay's AI, on its free hosted model or your Claude or ChatGPT in the chat, or your own agent over MCP, writes GDScript and scenes into your Godot project. It places props, builds rigged 3D models with the modeler, finds Godot plugins for you to install, and playtests the game: a headless run, stdout and parse errors, viewport capture, input events and the live scene tree. You judge the result by playing it.
Platform
Windows, macOS and Linux: the current release runs on 64-bit Windows with an Intel or AMD processor, on Macs with Apple Silicon, and as an x86_64 Linux AppImage. There is no web version, no browser editor, no browser preview, and no mobile app.
Who writes the code
Your AI does, and you can: it writes the GDScript into a real Godot 4 project, and Flockbay hosts the full Godot editor, Script editor included, beside the chat. You can open, read and change every file there, in stock Godot or in your own code editor.
Where the game runs
Output is a normal Godot project in a normal folder on local disk. Games run locally on the copy of Godot bundled with the app. No streaming, no cloud rendering, no cloud building.
Pricing
Free, AI included. Every account starts with free usage on Flockbay's hosted AI. Or build on your own AI: your Claude plan (Pro or Max) or your ChatGPT account (any plan, Free included) in the app, your own agent over MCP, or your own API key (OpenAI or Anthropic), and you pay the company that runs your model, never Flockbay. Optional plans add more hosted AI: Hobby at $20, Indie Developer at $60 and Studio at $200 a month. There is no team, per-seat, or enterprise plan. Projects and assets are private.
AI models
Free AI runs on Flockbay's hosted model, which Flockbay picks and the model menu names. On your Claude plan, Flockbay runs Claude Code, and the model menu lists the models and effort levels Claude Code gives you. On your ChatGPT plan, it runs your account's models through the bundled Codex engine. On an API key, it runs any model the key reaches, and an agent over MCP uses whatever model that agent runs.
What happens when a plan's usage runs out?
Turn on on-demand usage on Billing and Flockbay keeps building on your plan's models. Extra usage is charged at the on-demand rate shown on Billing, after you use it: at about $20 the first time, then each time it reaches about $50, and on the 1st of the month for the rest. You set a monthly limit. At the limit, or with on-demand off, the plan's hosted AI stops until the month renews. Building on your own AI is never affected. If a charge fails, on-demand usage pauses until it's paid; after 14 days unpaid, the plan pauses too. Or upgrade your plan, or wait for it to renew.
Who pays for ads?
You do. Meta, Google, TikTok or Reddit bills the ad spend to your own ad account, and Flockbay charges no fee on it. Flockbay drafts each campaign in the app, and nothing spends until you press Launch. Ads is a paid feature, available on the Indie Developer plan and above.
Is a website for my game free?
Building it is. Flockbay, or your own Claude, ChatGPT or agent, builds your game's website in the app from the game's own material; you preview it at desktop and phone widths and can export it as a .zip that runs on any static host. Publishing it on flockbay.app or your own domain is a paid feature, with email signups you export as CSV and views and Steam clicks counted without cookies.
What happens when the free usage runs out?
Flockbay's hosted AI stops until the free usage resets, every day at 00:00 UTC, and nothing is charged. There are three ways on: wait for the reset; upgrade to a plan, from Hobby up, for usage every month; or keep building on your own Claude or ChatGPT, your own agent over MCP or your own API key, which is free with no Flockbay limit. Images and sound generated on Flockbay's keys still come from the free usage or a plan. Your project stays as it is in its folder whichever you pick.
Which plan should I pick?
Pick by whose AI you build with and how close the game is to launch. On your own Claude, ChatGPT or agent, Free covers building; Hobby adds a first go at every launch tool (Steam page drafting, devlogs and Shorts, social posts, a website and playtest links), and Indie Developer adds what a launch needs: trailers and ad cuts, Ads, scheduled posts and more of each. Building on Flockbay's hosted AI every day, Hobby keeps a side project going, and Indie Developer gives 3× Hobby's usage and stronger models. A studio, or a big game with several people posting and testing, fits Studio: 10× Hobby's usage, the most capable models, and the most accounts, sites and playtest links.
Where does my project go?
Nowhere you do not send it. Your game is a folder on your machine, uploaded only to your own GitHub or as a playtest build you share. [Security: what leaves your machine](/security/) says what else does, and where.
