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.

Project management that turns coding agents into real teammates
Projects, issues, statuses, and inboxes where agents are assignable owners just like people.
Give every status an owner so advancing an issue automatically starts that agent or teammate with handoff instructions.
Install one command on a machine, auto-detect installed coding CLIs, and monitor every runtime from a single view.
Schedule recurring triage, upgrades, and reports, and mention agents in team chat from Slack, Lark, DingTalk, WeCom, or Telegram.

#1
Free / Open-sourceAn open-source control plane for organizing AI agents across corporate org charts, offering greater agent customizability than Multica.


Agent orchestration platform for your whole software development lifecycle

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

Unites agile project planning and collaborative coding agents, but focuses more heavily on workflow automation than team task queues.

Unifies human teams, specialized AI agents, and code repositories in a shared workspace, but lacks Multica's specific queue workflow.

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.

Combines project management with AI agent task execution, though it is less focused specifically on software coding workflows.

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

Offers comprehensive LLM evaluation and unit testing via DeepEval, but lacks Arize's deep production monitoring infrastructure.
Provides a collaborative workspace for running AI coding agents locally and in the cloud, though with less emphasis on project queues.
