The control plane for trusted enterprise agents and models
See the performance of every agent and predictive model in a single pane of glass, with every action, token and dollar traceable by user and team.
Fiddler Centor Models power policy enforcement and continuous evaluation inside your network, avoiding external LLM API calls and their hidden costs.
Detects and redacts PII, PHI and secrets on the same request path — before a prompt reaches the model and before a response reaches the developer — with sub-80ms latency.
Keeps a living inventory of every connected agent and records each enforcement decision, with who triggered it and what happened, ready for GRC and AI regulation audits.

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.

Free / Open-sourceRun many coding agents in parallel, each in its own worktree
#2
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
Unites agile project planning and collaborative coding agents, but focuses more heavily on workflow automation than team task queues.

Free / Open-sourceAgent observability, evaluation, and continuous improvement for production AI

Attack-led AI security testing and red teaming

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

Free / Open-sourceBuild, simulate, evaluate and monitor self-improving AI agents

Free / Open-sourceEvaluate, monitor, and govern your AI applications in production

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

Free / Open-sourceStandardize LLM evaluation, observability, and red teaming across your whole org
