AgentOps - Pros & Cons
Pros
- ✓Session replay with step-by-step execution graphs pinpoints exactly where and why an agent failed
- ✓LLM cost tracking across 400+ models and providers shows per-call, per-agent, and per-workflow spending
- ✓Framework-agnostic SDK with native integrations for CrewAI, AG2, Agno, OpenAI Agents SDK, LangChain, LangGraph, and CamelAI
- ✓Fully open-source under MIT license with self-hosting on AWS, GCP, or Azure for data sovereignty
- ✓Minimal instrumentation required — two lines of code to get started with basic tracking
- ✓Debug and audit trail catches errors, logs, and prompt injection attacks from prototype to production
Cons
- ✗Python SDK only — no official JavaScript/TypeScript, Go, or other language clients available yet
- ✗Free tier limited to 5,000 events, which multi-agent workflows can burn through quickly in development
- ✗Pro plan jump from free to $40/month may be steep for individual developers doing side projects
- ✗Self-hosted deployment requires managing both the dashboard frontend and API backend separately
- ✗Newer platform with a smaller community and fewer third-party resources compared to established APM tools like Datadog
Langfuse - Pros & Cons
Pros
- ✓Fully open-source with self-hosting that has complete feature parity with the cloud version
- ✓Hierarchical tracing captures the full execution tree of complex agent workflows, not just LLM calls
- ✓Prompt management with versioning and production linking creates a tight iteration feedback loop
- ✓Native integrations with LangChain, LlamaIndex, OpenAI SDK, and Vercel AI SDK require minimal code changes
- ✓Evaluation system supports both automated LLM-as-judge scoring and human annotation queues
Cons
- ✗Dashboard analytics are functional but less polished than commercial observability platforms for executive reporting
- ✗UI performance degrades noticeably with very large trace volumes (millions of traces)
- ✗ClickHouse dependency for self-hosting adds operational complexity compared to PostgreSQL-only setups
- ✗Documentation can lag behind feature releases, especially for newer evaluation and dataset features
