Concat
Open-source, local video editor built in Rust as a CapCut alternative
Emerged finds new products worth a look, daily — what’s new today
If you edit short video and resent CapCut's account, watermark and upsell, Concat gives you multi-track editing, local transcription and free TTS voices as an AGPL download for every platform.
Concat is Jareer A.'s open-source video editor, written in Rust, that does the CapCut job without the CapCut terms. Everything runs on your machine: multi-track timelines, split, trim, merge, transitions, speed changes, captions transcribed offline, text-to-speech from local voices, voice filters, titles, templates, and full-quality export with nothing stamped on it. MCP is exposed so an agent can drive an edit. Builds ship for Windows, macOS, Linux on x86 and ARM, Android, and experimental iOS, from a v0.2.3 beta of about 77 MB. AGPL-3.0, 3.2k stars, 582 commits, public roadmap.
