Weave Router
A model router that sits in front of Anthropic, OpenAI and Gemini APIs and picks the best available model for each request using a small on-device embedder rather than a prompt-based heuristic.
Weave Router acts as a drop-in proxy: pointing Claude Code, Codex, Cursor or a custom app at its local endpoint lets a cluster scorer, derived from Avengers-Pro, pick a model per action (rather than per whole conversation turn) from the providers a user has enabled.
It speaks the Anthropic Messages, OpenAI Chat Completions and native Gemini APIs, including streaming, tools and vision, and also routes to open models such as DeepSeek, Kimi, GLM, Qwen, Llama and Mistral through OpenRouter or another OpenAI-compatible endpoint. Provider keys stay on the user's machine, encrypted at rest, and it emits OpenTelemetry traces viewable in a bundled dashboard or an external tool such as Honeycomb, Datadog or Grafana.
It installs with a hosted quickstart command or self-hosts with Postgres via a make full-setup target; it is written in Go.
