PerfLens goes beyond a one-time Lighthouse score by keeping performance feedback inside the browser while you build and test. It gives developers live Core Web Vitals, resource diagnostics, root cause summaries, per-URL history, AI-ready fix prompts, and launch evidence packs with desktop/mobile audits, screenshots, videos, and JSON reports. The goal is simple: help developers move faster from “this is slow” to “here’s what to fix next.”
I built PerfLens because performance audits often stop at a score, but developers still need to understand what caused the issue and what to fix next.
I wanted a tool that works inside the browser, including localhost, and gives live Core Web Vitals, resource diagnostics, history, and AI-ready prompts for specific issues.
As I built it, the idea evolved from a simple audit extension into a workflow tool for debugging, fixing, and collecting launch evidence before shipping.

Who hunted PerfLens?
PerfLens was hunted by Olamilekan Lamidi. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
