Spin up a throwaway Flarum — and let AI build in it.

A disposable Flarum instance for developing and troubleshooting extensions and themes. Connect your AI (Claude, Cursor, any MCP client) and it can install extensions, read logs, and diagnose your forum — in a sandbox you can break without consequence.

Real Flarum, instantly
A genuine Flarum 2.0 install on MariaDB — the same database the extension ecosystem is built for — on its own subdomain, not a mock. Ready in about a minute.
AI build + troubleshoot
A built-in MCP endpoint in write mode with the extension manager: your AI installs extensions, edits content, and runs read-only diagnostics.
Disposable by design
Minimal footprint, no backups. Shut it down anytime to stop the meter; idle sandboxes are cleaned up after a day. Break it freely; launch a fresh one.

How it works

  1. Add prepaid credit, then hit Launch — your sandbox provisions on its own subdomain in about a minute.
  2. Point your MCP client at the sandbox’s /mcp endpoint (shown on your sandbox page).
  3. Build, install extensions, and troubleshoot — with AI driving if you like. It meters at $1/hour while running.
  4. Shut it down to stop the meter; idle sandboxes are removed after a day. Launch another anytime.
