Lightpanda Measured: 40,121 Stars, 98 Watchers, and 62% of Its WPT Passes Come From One Encoding Suite

Lightpanda is a browser written from scratch in Zig, with no Chromium and no rendering engine, aimed at the one workload that grew fastest in 2026: agents reading the web. It left beta on 2 October 2026 with version 1.0, and on 2 November 2026 the repository shows 40,121 stars. Its README opens with a two-line claim — “16x lighter and 9x faster than Chromium” — and a table.

I downloaded the nightly build, ran it against ten real pages alongside Playwright’s Chromium, connected to its CDP server with Playwright, and then parsed the raw JSON behind its public Web Platform Tests dashboard instead of reading the pass counter. Three things came out of that work that the README does not say.
