Laminar
Solid open-source AI agent observability platform with strong docs and integrations but limited as a standalone agent executor due to focus on tracing rather than execution.
Viable option — review the tradeoffs
You need to debug why your LLM agent failed—which tool it called, what parameters it used, how the LLM interpreted the tool output, and where the chain broke.
Fast trace ingestion (Rust-powered, gRPC transport, millions of traces/day). Hierarchical span view with latency, token counts, and cost. Browser agent video sync works well but adds storage overhead. SQL editor for custom analysis is powerful but requires learning their schema.
You're iterating on prompts and agent logic but have no systematic way to catch regressions or measure whether your changes actually improved performance.
Evaluations run fast and results stream in real-time. You avoid managing evaluation infrastructure yourself. Custom evaluators are flexible but require you to define what 'correct' means for your use case. No built-in A/B testing framework—you manage experiment design.
You're running millions of agent sessions in production and need to quickly surface patterns—which failures are most common, which users hit which edge cases, what's the latency distribution across regions.
Signals are a novel feature—they work well for common patterns but may require iteration to refine for edge cases. SQL editor is powerful for power users but adds cognitive load. Clickhouse backend handles analytics at scale.
Not an agent executor—tracing only
Laminar is observability-first. It does not orchestrate or run agents. You must build and host your agent elsewhere (LangChain, CrewAI, custom code) and instrument it with Laminar's SDK. If you need a platform that both executes and observes agents, you'll need a separate tool.
Browser agent video storage can grow quickly
Browser agent observability captures full screen recordings synced with traces. This is powerful for debugging but generates large payloads. Self-hosted deployments need adequate storage; cloud deployments may incur unexpected costs if you're recording thousands of sessions daily.
Trust Breakdown
What It Actually Does
Laminar lets you monitor AI agents by tracing their LLM calls, tool uses, and performance metrics like latency and cost in real time. It also runs evaluations, builds dashboards, and queries data with SQL to debug and improve reliability.[1][3][6]
