fx°
managed by jurniti · upstream Vercel Labs
Run fx — Vercel Labs' 6MB Zig coding agent — on a real microVM. Unix-shell form factor, not an IDE in the terminal.
- Fresh Ubuntu microVM with the fx binary pre-installed and on your PATH (~6.4 MiB, no Node runtime).
- Live in-browser terminal — `fx login` is Vercel device-code (PTY-safe), or `fx setup` / AI_GATEWAY_API_KEY.
- Persistent home — settings, skills, and AGENTS.md survive every restart.
- Snapshot into a forkable template — share MCP wiring and skills, never auth.json or api-key (scrubbed on publish).
- Real Firecracker microVM isolation. Not a shared Docker container.
Flat monthly · no metered surprises
$21/mo Starter($250/yr billed yearly · 2 months free)
30-day money-back guarantee — no free trial. Provision in ~3 minutes after payment. fx is already on PATH — open the in-browser terminal and run `fx login` (Vercel device-code) or `fx setup`.
