Polypane 29 ships a redesigned panel UI with single-level navigation and drag-and-drop reordering, a brand-new network panel offering multi-pane load performance overviews, Web Vitals timings, per-origin connection details, and a full request waterfall table. A snippet store lets developers browse, install, and contribute community snippets directly from the browser. Other highlights include grid/flex visualizations in Polypane Peek, inspectable iframes, a custom CSS selector overview in the outline panel, passkey keychain integration on macOS, WhatsApp link preview in the Meta panel, service/shared worker inspection in DevTools, and numerous accessibility tree and elements panel improvements. The release is built on Chromium 148 with the html-in-canvas API enabled by default.
