fi: open-source coding agent that rides on your existing AI subscriptions
Great_Ad2919 · reddit · 2026-11-15
fi is an MIT-licensed, local-first coding workspace (desktop/web/CLI) that signs into subscriptions you already pay for — Claude, ChatGPT/Codex, Grok, plus browser sign-in for GitHub Copilot, Cursor, Kiro, Cline, Gemini Code Assist, Antigravity, Ollama Cloud, and custom OpenAI/Anthropic-compatible endpoints — instead of requiring new API keys. The agent loop covers file tools, terminals, planning, subagents, persistent conversations, per-turn change restore, and managed Git worktrees; search uses subscription-native search or free Bing. The author notes sign-in doesn't guarantee inference: quotas stay with providers. Built on DeepSeek Harness and Cordis, v1.0.1, signed macOS builds.
