Free cloud builds for your AI agent: 10,000 coins, no credit card

AI agents write code in minutes now. The expensive part sneaks in afterwards: build runners, test environments, APK toolchains — and most cloud CI services want a credit card before you can even try.

As a developer myself, that's exactly what I didn't want for my build platform. So on Roun, signing up gives you 10,000 coins free — no card, no trial timer, no "contact sales" wall. Enough to run dozens of real builds while you learn the workflow.

What the coins pay for

Coins are the credit for real work on isolated cloud runners:

npm run build for JS/TS projects
go build, cargo, pytest for backend and Rust projects
gradle assembleDebug — yes, full Android APK builds
compile_fix: when the build fails, the AI reads the error log, patches your source and retries (up to 3 times)

Peace-of-mind part: every request shows an estimated coin cost before it runs, coins are held, then charged against the actual result — not the guesswork. No surprise bills for a failed queue.

What I'd do with fresh 10k coins today

Hook your agent up once — sign up, copy your key from the dashboard, paste one config block:

{
  "mcp": {
    "codebridge": {
      "type": "remote",
      "url": "https://api.roun.sryze.cc/api/mcp",
      "headers": { "Authorization": "Bearer YOUR_KEY" }
    }
  }
}

Works in OpenCode, Claude, Cursor, ChatGPT — any MCP client.

First build: drop 2–3 files and say "compile my files"
Break something on purpose, then say "compile_fix" and watch the AI read its own error, patch, and pass
Build an APK from a tiny Android demo without installing Android Studio locally
Bonus: the Game Studio — describe a game in a sentence, play the HTML build instantly

When you outgrow free

Pricing is per-result and transparent; you only move when project volume makes it worth it. Until then the free coins cover genuine experimentation.

I built a Game Studio where you type one sentence and get a playable game in seconds

I keep a notebook full of game ideas I never ship. Every one of them needs a loop, art, physics tweaks, a build pipeline — the friction kills the fun long before the code starts.

So I built something different into my platform, Roun: a Game Studio where you describe a game in one sentence and get a playable single-file HTML5 build right in the browser. No project setup, no deploy, no download.

Examples that work right now:

"neon snake, walls shrink every 10 seconds" → playable snake
"astronaut dodges asteroids, retro CRT filter" → playable dodger
"bubble shooter but the bubbles are cats" → exactly what it says

How it works

Type a sentence in plain English.
Roun plans the game loop and generates the code, then runs a real build on a cloud runner.
You get a playable preview immediately — one HTML file, saved to your game history, shareable by URL.

Single file was a deliberate constraint. It forces tight scope, instant loading and zero-install play — the questions players ask changed from "what engine is this?" to "can I play again?"

Your coding agent can play too

Same platform also exposes MCP tools, so you can ask your agent (Claude, Cursor, ChatGPT) to make a game inside your chat:

{
  "mcp": {
    "codebridge": {
      "type": "remote",
      "url": "https://api.roun.sryze.cc/api/mcp",
      "headers": { "Authorization": "Bearer YOUR_KEY" }
    }
  }
}

Say "make me a tiny game" and the build comes back into the conversation.

Try it

Game Studio: roun.sryze.cc/game
Main platform (cloud builds for agents, free 10k coins): roun.sryze.cc

Drop a sentence a AAA studio would never greenlight and tell me what came out. The weirder the better.

How I run real builds from my AI coding agent (compile, auto-fix APK) without CI YAML

Tanvir Islam — Fri, 23 Oct 2026 10:21:06 +0000

I use AI coding agents (Claude, Cursor, ChatGPT) to write code all day now. But the moment the code leaves the chat, the babysitting starts: copy files into a CI dashboard, watch a queue I can't influence, read a red log, guess the fix, retry, wait again. The agent writes the app in 5 minutes; the shipping burns the evening.

So I built something to kill that loop: Roun — an agent-native cloud build service. One request from your agent or the web, a real build runs on an isolated cloud runner, failures get repaired automatically, and the artifact (logs, binaries, APKs) comes back to you.

The whole loop in one sentence

Request → cloud build (compile + AI auto-fix) → result.

No runners to install, no CI YAML to babysit, no local toolchain to maintain. The agent stays in the loop while the work happens somewhere else.

It speaks MCP, so your agent already knows how

Roun runs a remote MCP server. Point your coding agent at it once:

{
  "mcp": {
    "codebridge": {
      "type": "remote",
      "url": "https://api.roun.sryze.cc/api/mcp",
      "headers": { "Authorization": "Bearer YOUR_KEY" }
    }
  }
}

Then inside the chat you just say "compile my attached files" (or compile_fix to auto-repair errors). ChatGPT, Claude, Cursor and any other MCP client read the same config shape.

Real toolchains, not a simulator

The isolated runners execute actual commands: npm run build, go build, cargo, pytest, gradle assembleDebug — Python, Node, Go, Rust, Java, C++, Swift, PHP and more. When the build fails, Roun reads the error context, patches the source and retries up to three times before giving up.

Coins are estimated up front, held, then charged against the real output — you don't pay for guesswork. The free plan includes 10,000 coins and no card is required.

Bonus: Game Studio

Same account also has a Game Studio: describe a game in one sentence ("neon snake"), and you get a playable single-file HTML5 build right in the browser.

Try it

Website: roun.sryze.cc
MCP endpoint: https://api.roun.sryze.cc/api/mcp

If you test it, tell me which toolchain you connected first — I'm curious what people point their agents at.
