Cap (23k stars, active Oct 2026) is the closest open-source match for Loom: a Tauri desktop app records screen, camera and mic, then either uploads while recording for an instant link or opens a local editor (trim, zoom, captions). Cap Web adds share pages, comments, reactions, transcripts, AI titles and summaries, viewer analytics and team workspaces, and self-hosts with Docker Compose. Code is AGPLv3 (some capture crates MIT). The official desktop binaries need a paid commercial licence for work use; builds you compile yourself do not. AI features need your own provider keys.
