Agenta
Agenta is in transition from an LLMOps tool to an agent workspace, which makes it interesting for teams that want shared agents with tracing and evaluation baked in, and open source underneath. If you only need prompt management and evals, check that the current product still fits that narrower job. The MIT licence and self-hosting option lower the lock-in risk.
Pros
- MIT-licensed core that can be self-hosted with Docker
- Free cloud tier plus a $29 Pro plan
- Human-approval controls for agent actions
- Tracing, usage and version history for every agent
Cons
- The product direction changed recently, so older tutorials may not match the interface
- Free cloud tier limits team members to two and trace retention to one week
- Runs beyond the included allowance are billed per 10,000
