Every LLM app needs the same six things: proxy routing, cost tracking, caching, observability, audit trails, and safety filters. That's 6+ separate tools, each with its own database and Docker setup. Stockyard replaces all of them with one Go binary. 66 middleware modules. 16 LLM providers (OpenAI, Anthropic, Gemini, Groq, Ollama, and more). Embedded SQLite — no Redis, no Postgres. Install in 30 seconds, dashboard included. MIT licensed. Self-hosted is free forever with no limits.
