Splera - A/B testing that runs inside your AI coding tool

Lovable, Replit and Bolt ship UI changes in seconds, but nobody tells you if they helped. Splera does. Its Chrome extension works right inside your AI tool (Replit, Lovable, Bolt and Claude Design). When the AI changes something, Splera suggests an experiment and injects the setup prompt into the same chat, so the AI wires up the test for you. No test code to write. Using another AI agent? Describe the test on the web dashboard and paste the generated prompt into any agent. Results use Bayesian statistics, so you get a usable answer even on small traffic. Ship the winner with one click: every visitor gets it within 30 seconds, no redeploy. After shipping, Splera keeps watching the winner and alerts you (or rolls back automatically on Pro) if conversions drop. Free plan, no credit card.

Splera is a strong fit if you are one of: • data-driven founders and growth teams • developers, engineers, and technical founders If that does not sound like you, skim the features and site before committing time.

Splera is built around this outcome: For founders building with Lovable, Replit or Bolt: when your AI changes the UI, Splera suggests an A/B test, sets it up in the same chat, and tells you which version wins. Use the site demo or docs to confirm it matches the bottleneck you are trying to remove.

Splera uses AI as part of its workflow. Before relying on it for customer-facing or confidential work, confirm what data is sent to models, whether outputs are editable, and how you can review results.

It promises: For founders building with Lovable, Replit or Bolt: when your AI changes the UI, Splera suggests an A/B test, sets it up in the same chat, and tells you which version wins. Worth trying if that problem is painful for you this week; skip it if you only need a one-off workaround you already have.

Open the official Splera website from this page, run the smallest real task you care about (not a toy demo), and decide in one session whether it removes friction. Check pricing and data/privacy terms before you put production work into it.
