Agent observability, evaluation, and continuous improvement for production AI
Capture spans, traces, and sessions across agents and LLM calls using OpenInference conventions built on OpenTelemetry, so instrumentation stays portable.
Run evaluations at span, trace, and session level to grade retrieval quality, tool use, and final answers across large production datasets.
An in-product agent that inspects traces, diagnoses likely root causes, and proposes fixes that engineers can review before shipping.
Self-host the leading open-source tracing and eval tool when you need to keep trace data inside your own infrastructure.
Open-source workflow automation built for AI agents and technical teams
Build automations with a visual node editor, then insert JavaScript or Python code nodes when you need custom logic.
Connect to 500+ native services, any REST API via HTTP nodes, and any agent or coding assistant through MCP.
Run agents alongside regular steps, inspect every decision, and add structured inputs, guardrails and human approval steps.
Watch workflows execute live, open past runs, replay a run with mocked data and re-run just the step that failed.

No-code builder for custom AI agents and workflows

Free / Open-sourceOutstanding open-source visual canvas for RAG pipelines and LLM agents, but less suited for general API integrations.


SpecialistMultiplayer AI where people and agents work side by side
Turn one prompt into live business apps, AI agents and automated workflows
Powerful visual builder specifically tailored for complex AI agent workflows, but less mature for traditional enterprise automation.

Excels at experiment tracking and model registry workflows, but is less purpose-built for real-time LLM production observability.

SpecialistDeveloper-first integration platform with granular code control, but lacks n8n's visual node-based workflow builder.

Enterprise-grade security and robust workflow automation, but less focused on open-source self-hosting and consumer use cases.
Free / Open-sourceAn open-source no-code automation tool with a clean interface, but fewer native app integrations than n8n.

No-code AI agents and agent teams for real business workflows

Free / Open-sourceOpen-source workspace for building and governing agent systems, but has a smaller community and fewer integrations.
