The Open Source LLM Router for AI Agents | Manifest
It's an LLM gateway, but with HA, fallback, and observability.
I want to try it out against LiteLLM. It'd be handy to funnel every agent's requests into one place, especially with team agents (https://andysmith.ai/2026/Aug/19/ai-doesn-t-work-in-a-team-and-how-to-fix-it/, https://andysmith.ai/2026/Aug/17/the-shared-context-problem-on-teams-that-use-ai/).
If the observability covers the main things LangFuse does, it looks like a pretty solid all-in-one.
