Show HN: Mix – Open-source multimodal agents SDK Why we built it: • Claude Code: great for coding, but no video/audio support, localhost only • OpenAI SDK: single-model, no native multimedia tools • Both: no integrated DevTools for debugging agent reasoning So, we built Mix as an alternative for multimodal applications. • Native video/audio/PDF analysis tools (via Gemini for vision, Claude for reasoning) • Multi-model routing instead of single-provider lock-in • One-command Supabase setup for cloud deployment (vs localhost-only) • HTTP architecture that enables visual DevTools alongside agent workflows • Go backend: 50-80% lower memory footprint than Node.js—efficient for concurrent agent sessions. Python and typescript clients are available Example use cases in the demo video: portfolio analyzer that reads Excel and generates charts, YouTube search agent that finds and edits video clips.
