LangObs

LangObs is a collaborative observability platform for multi-agent AI systems — Loom for what your agent did, Figma comments for what your team thinks about it, and a budget alarm for what it cost. You describe a task in plain English. Gemini 2.5 Pro generates a typed multi-agent workflow graph. The Vercel AI SDK 6 runner executes each agent and streams every token, tool call, cost, and guardrail event into Supabase as a structured span in real time. The result is a shareable, commentable, voice-narrated session replay that any teammate can open in a browser — no SDK changes, no vendor lock-in, no proprietary collector required.
