When to use each

When to use Zenbase

Zenbase is excellent for developers optimizing prompts during the build phase:

  • Integrated into the development workflow
  • Programmatic prompt optimization with code
  • Works with popular LLM frameworks
  • Compile-time optimization for predictable results
  • Developer-friendly API and configuration

When to use Converra

Converra is built for teams who need production agents to improve without engineering overhead:

  • Works on production agents without code changes
  • Continuous improvement from real failure patterns
  • Head-to-head simulation validates every change
  • No training dataset required to start
  • Governed deployment with versioning and rollback

Zenbase optimizes at build time. Converra optimizes in production.

Different tools for different lifecycle stages

Zenbase and Converra aren't direct competitors. They operate at different points in the AI development lifecycle.

Build time (Zenbase)

  • • Optimize during development
  • • Define optimization in code
  • • Use training examples to compile
  • • Ship optimized prompts

Production time (Converra)

  • • Connect production data sources
  • • Auto-generate from real failure patterns
  • • Simulate and validate offline
  • • Deploy with gating and rollback

Frequently asked questions

Can I use both?

Yes. Zenbase for build-time optimization, Converra for continuous production improvement.

I optimized with Zenbase during development. Why do I need Converra?

Production is different from dev. User behavior shifts, models update, edge cases emerge. Converra handles drift that build-time optimization can’t anticipate.

Do I need code changes to use Converra?

No. Converra works from your production traces. No SDK integration or code changes required.

What about Zenbase's framework integrations?

Zenbase integrates with LLM frameworks at the code level. Converra operates above the framework layer, optimizing the prompts your frameworks use.

Is Converra a Zenbase alternative?

Different stages of the lifecycle. Zenbase is build-time. Converra is production-time. If your prompts need to improve after deployment, Converra is what you need.
