Is runab right for you?

We built runab to do one thing well. That means it's not for everyone — and we're okay with that.

When runab is the wrong tool

runab is intentionally minimal. If you need advanced experimentation features, you'll probably be happier elsewhere.

  • Multi-variant experiments with complex traffic allocation
  • User segmentation and cohort analysis
  • Funnels, dashboards, and analytics suites
  • Marketing-led experimentation workflows
  • Enterprise SSO, audit logs, and compliance features
  • Cross-device tracking and user identification

Tools like Optimizely, VWO, or LaunchDarkly are designed for complex experimentation workflows. If that's what you need, they're great options.

When runab is the right tool

runab is for developers who want to test an idea, get an answer, and ship. No complexity, no noise.

  • 1Split traffic 50/50 between two variants
  • 2Track a single conversion event
  • 3See which variant wins
  • 4Ship it and move on

Why we built it this way

Most A/B testing tools are built for marketing teams running dozens of experiments with complex targeting rules. They charge for visitors, require configuration, and come with dashboards you'll never use.

runab is built for a different workflow: you have an idea, you want to test it, and you want to know if it works. That's it.

We intentionally avoid features that don't help you make a decision faster.
