Useful when an agent farm pays for one default frontier model on every call.","theCatch":"Elastic License 2.0 is source-available, not OSI open-source — you may not offer Weave Router as a hosted/managed service under ELv2 without permission. Vs LiteLLM: LiteLLM is the broader multi-provider gateway/SDK; Weave Router's wedge is per-prompt model selection via on-box embeddings. Routing quality still depends on your traffic mix and evaluation.","verdict":"ELv2 source-available model router. Strong cost lever for agent fleets; no managed offering without a license review.","addedAt":"2026-09-20","featured":false,"domain":"AI Agents","subSpecialty":"Tooling","subcategory":"Tooling","tags":["source-available","active","young-repo"],"capabilities":["routing","proxy","cost"],"surfaces":[],"ecosystem":["Go","Multi-platform"],"licenseModel":"Open-Core","githubStars":5598,"starsPerWeek":223,"access":"free","archived":false,"repo":{"createdAt":"2026-04-27","pushedAt":"2026-10-18","license":"Apache-2.0","archived":false,"checkedAt":"2026-10-19"}},"related":[{"slug":"claude-code","name":"Claude Code","tagline":"Terminal-first coding agent with deep repository context"},{"slug":"cursor","name":"Cursor","tagline":"The AI-first code editor that understands your codebase"},{"slug":"devin","name":"Devin","tagline":"Autonomous AI engineer for defined engineering tasks"},{"slug":"stagehand","name":"Stagehand","tagline":"AI-native browser automation that mixes code and natural language"},{"slug":"browser-use","name":"Browser Use","tagline":"Open-source framework for LLM-driven browser agents"}],"links":{"self":"/api/gems/weave-router","html":"/gems/weave-router","markdown":"/gems/weave-router.md","category":"/api/gems?category=agents","categoryPage":"/stacks/agents"}}
