About Needlr

Needlr is a release impact tool. It tells product teams whether a release moved a business KPI, with split tests, before vs after checks on past releases and feature adoption, set up through Google Tag Manager. No engineers needed, and coding agents can ask it too.

Why it exists

Most teams ship every week and measure almost none of it. A/B testing tools answer the tests you planned in advance. Most changes are never planned as a test: they just go live, and nobody knows if they helped.

Needlr answers the question for everything you ship: did it move the needle? When a split test is possible, it runs one. When the change is already live, it compares the weeks before and after, with a check for trends that were already under way. Every verdict says how sure it is, and when it can't tell, it says so.

The statistics are public: how a verdict is reached and how often it is right.
