LastBrowser is an open-source (GPL-3.0) web browser for Windows and Linux (Linux preview); an Apple version is planned. It is local-first: history, tabs, sessions and passwords stay on the user's machine, with no hidden telemetry. Features include a collapsible vertical tab sidebar with workspaces, a split view, a command palette, incognito mode, one-click browsing data cleanup, session snapshots, bookmark import/export and Manifest V3 WebExtensions support (e.g. uBlock Origin Lite, Bitwarden, Dark Reader). It ships with Sidekick, a built-in AI agent that users can connect to providers of their choice (bring your own key). LastBrowser currently has a few hundred users.
