Supported agents

The agent CLIs Open Free Max drives — Claude Code, Codex, OpenCode, Gemini, Vibe and Kimi Code — and how provider support is structured.

OFM is bring-your-own-agent. It drives the official CLIs you already have installed and logged in; it never bundles, updates or proxies them.

Supported CLIs

Provider adapters

Each provider is described by a small declarative adapter that knows how to:

• launch the binary in interactive mode (with the right session/resume flags);
• apply your settings (model, effort, permission mode, allowed tools, MCP config, …) as launch flags — configured once in Settings;
• read its screen to detect state and confirmation prompts.

Adding a new CLI is one adapter — the rest of the app is provider-agnostic.

Autonomy levels (A / B)

Not every CLI exposes its confirmation prompts identically, so OFM grades providers:

• Level A — driven (Claude Code): OFM reliably classifies its screen and confirmation boxes, so it can fully auto-resolve and run autonomously per your rules.
• Level B — assisted (others, initially): the engine still runs them — dispatch, leasing, quota parking — but their confirmations always go to the human queue rather than being auto-answered blindly. No CLI is ever excluded; a level-B provider just asks for a hand more often.

In Plan, the chosen CLI’s level is shown on the campaign form so you know up front whether a batch will run hands-off or surface confirmations.

Authentication

You sign in where you already do — inside each official CLI. OFM never sees your tokens or keys. See Subscription vs API.
