When to use each

When to use Opik

Opik is excellent for developers building eval infrastructure:

  • Developer-friendly eval SDK with Python/TypeScript support
  • Experiment tracking and comparison dashboards
  • LLM tracing with cost and latency visibility
  • Dataset management for systematic evaluation
  • Open-source core with self-hosting option

When to use Converra

Converra is built for teams who need agent failures fixed, not just measured:

  • Fixes failures, not just measures them
  • No eval dataset required to start
  • Simulation testing validates changes offline
  • Continuous improvement without writing eval code
  • Governed deployment with versioning and rollback

Opik helps you evaluate. Converra helps you improve.

Different approaches to the same goal

Opik gives developers tools to measure. Converra closes the loop from measurement to validated fix.

SDK approach (Opik)

  • • Write evaluators in code
  • • Run experiments manually
  • • Build datasets over time
  • • Compare runs in dashboards

Production approach (Converra)

  • • Connect production data
  • • Auto-generate targeted fixes
  • • Simulate and validate offline
  • • Deploy with gating and rollback

Frequently asked questions

Can I use both?

Yes. Different tools for different parts of the lifecycle. Opik for custom eval infrastructure, Converra for automated improvement.

I already have evals in Opik. Do I need to rebuild?

No. Converra generates test coverage from production patterns. Your Opik evals remain useful for your own validation.

Does Converra replace Opik's tracing?

No. Opik gives excellent trace visibility. Converra adds the improvement loop.

Opik is open-source. How does Converra compare on flexibility?

Opik's open-source SDK gives you full control over eval logic. Converra trades that control for automation — it handles variant generation, simulation, and deployment end-to-end.

Is Converra an Opik alternative?

Different tools. Opik is eval infrastructure. Converra turns failures into tested fixes. If you need prompts to improve automatically, Converra is what you need.
