FAQ

Frequently asked questions about Open Free Max — billing, API keys, platforms, the Plan bulk orchestrator, and how it compares to Electron IDEs.

Do I need an API key?

No. OFM never touches your tokens, keys or auth. It launches the official agent CLI, which handles its own subscription login. You sign in once where you already do. See Supported agents.

How does billing actually stay on my subscription?

OFM only ever drives the official CLI in interactive mode — a real human typing and reading. It deliberately avoids the SDK, headless -p, and ACP paths that are billed against the metered programmatic pool. Full explanation: Subscription vs API.

What is Plan / bulk mode?

Plan turns OFM into an autonomous orchestrator. You give it one repetitive job — a list of units and a prompt — and it runs a pool of interactive sessions in parallel until the batch is done. It survives crashes and reboots, and because it stays on your subscription it expects to hit token limits: it parks and auto-resumes when your plan refreshes. Each unit writes its own output, so the run is idempotent and fully resumable.

Will a big bulk run blow up my bill?

No — that’s the point. Every unit is an interactive session on your subscription, never an API call. You’ll periodically hit your plan’s usage cap; Plan turns that into an invisible pause-and-resume rather than spilling onto metered credits.

Which platforms are supported?

Windows (with native WSL2 project support) and macOS — the Tauri core covers both with a small, native footprint. See Install.

Can I lose a conversation?

No, by design. OFM never owns the transcript store — it leans on each CLI’s durable history and rebuilds its session map from disk if needed. See Sessions & persistence.

Why not just use Cursor or a VS Code fork?

Those embed Chromium plus the VS Code extension host (heavy), and re-implement session storage — the place where agent conversations get lost. OFM stays thin, leans on the CLI’s own store, and uses up to 200× less RAM. See How OFM works.

Which agents can it drive?

Claude Code, Codex, OpenCode, Gemini, Vibe and Kimi Code — the official CLIs you already have. One adapter per provider, no lock-in. See Supported agents.

Is it free / open?

OFM drives the agents you pay for and adds no metered layer of its own. See the download page for the latest builds.
