Reviewer scorecard
“Best open-source LLM observability. Traces, prompt versioning, and evals in one tool. Self-hosting option is a must.”
“Long-running jobs up to 24 hours solve the AI agent execution problem. The v3 architecture is built for modern workloads.”
“Open source means no vendor lock-in. The tracing UI is clean and the integration with LangChain and Vercel AI SDK is seamless.”
“v3 addresses the key limitation — jobs that need to run for hours, not just seconds. Essential for AI agent tasks.”
“LLM observability is becoming as essential as APM. Langfuse is the Grafana of AI — open source and community-driven.”
“Long-running, durable background jobs are the infrastructure AI agents need. Trigger.dev v3 delivers exactly this.”
