Reviewer scorecard
“Best open-source LLM observability. Traces, prompt versioning, and evals in one tool. Self-hosting option is a must.”
“Universal code search across repos is a superpower for large orgs. Cody AI assistant with full codebase context is excellent.”
“Open source means no vendor lock-in. The tracing UI is clean and the integration with LangChain and Vercel AI SDK is seamless.”
“If you have more than 10 repos, Sourcegraph pays for itself in developer time saved on code navigation.”
“LLM observability is becoming as essential as APM. Langfuse is the Grafana of AI — open source and community-driven.”
