The release also adds Side Panel and tabCapture extension API support, a rewritten video recording engine with sound and lower memory use, and major Network panel upgrades (per-origin/all-request toggle, filtering, initiator highlighting). Elements, Console, Outline, Meta, and Peek panels get numerous accessibility, CSS, and usability improvements, plus new emulation features like text-scale and svh overlays, new device previews, project-specific default tabs, and text-selection syncing across panes and Portal-connected browsers. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is Polypane Playgrounds and how does it let me test a local site over HTTPS? Playgrounds, introduced in Polypane 30, lets you select any local directory and open it as a real URL over HTTPS without setting up a local server, managing ports, or dealing with self-signed certificates. It gives access to security-restricted APIs, cookies, and localStorage, supports live reloading, SPA fallback for client-side routing, directory listings, and can be shared across devices via Polypane Portal. _daily.dev surfaces browser tooling updates like this for developers testing responsive sites locally._ ### What version of Chromium does Polypane 30 use? Polypane 30 is built on Chromium 152, which powers its rendering engine and devtools. The release also adds support for newer web platform features tied to this Chromium version, alongside a fully rewritten video recording implementation and Side Panel extension API support. _developers tracking browser engine versions can follow releases like this on daily.dev._ ### Does Polypane's video recording feature support audio? Yes, as of Polypane 30 the video recording implementation was fully rewritten to process videos essentially instantly, use much less memory, and capture any sound playing in the pane, saving output as webm files. Previously recording lacked sound support and was slower with a higher memory footprint. _daily.dev helps developers stay current on tooling changes when choosing a browser testing workflow._ ## Community discussion Top comments from developers on daily.dev. **@pdfopsdev** · 0 upvotes > local dir over real https without touching mkcert or nginx configs is the actual killer feature here. webhook and oauth callback testing is where self signed certs cause the most pain, glad someone's finally solving that instead of another devtools panel. --- Tags:
