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 desktop AI workforce that runs browser, file, and app tasks for you
A coordinating agent breaks a goal into steps and dispatches specialist browser, terminal, document, and research agents that work in parallel inside a local workspace.
The desktop app is open source and can run locally or be self-hosted on your own infrastructure with your own keys, so data and secrets stay under your control.
Connect cloud providers, enterprise gateways, or local models and switch between them without rebuilding workflows; use your own API keys or free local models.
Follow each agent's searches, sources, and file changes, compare versions, then approve, revise, or ask a follow-up before accepting output.

#1Free / Open-sourceOpen-source workflow automation platform with integrated AI agent nodes, but lacks Eigent's native desktop terminal and file manipulation.
#2
Desktop AI workspace that turns task briefs into completed office deliverables, but lacks open-source transparency.
#3
Free / Open-sourceOpen-source personal AI assistant running locally, but focuses more on messaging integrations than heavy terminal orchestration.
Generates business apps and automated agents from text prompts, but functions primarily as a collaborative cloud workspace.
Visual no-code AI agent builder for web and data workflows, but executes in the cloud rather than local desktop.

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

No-code platform for building specialist multi-agent workforces, but lacks local desktop execution capabilities.

Free / Open-sourceRuns local collaborative teams of AI agents on your desktop, but features a less mature developer ecosystem than Eigent.

Free / Open-sourceIncludes integrated guardrails and simulation tools, but is less mature for large-scale enterprise production telemetry monitoring.

Free / Open-sourceFeatures strong testing and prompt evaluation tools, though its monitoring interface is less oriented towards massive telemetry streams.

Focuses heavily on prompt management and versioning control, whereas Arize prioritizes end-to-end tracing and ML observability.
