About
Concat is a free, open-source video editor and a CapCut alternative for macOS, Windows, Linux and Android. It covers what people actually open CapCut for: auto-captions, text-to-speech, background removal, keyframe animation, effects and titles, multi-track cutting, 4K export. With none of the catches: no watermark, no account, no subscription, no upload.
Everything runs locally on a native Rust engine with a GPU compositor. Install it, drop in footage, cut. The AI models for captions, voices and cutout download once from Settings and work offline after that. Your footage never leaves your disk.
Good for: TikTok, Reels and Shorts, YouTube videos, tutorials and screen recordings, podcast clips, memes.
Also for machines: a built-in MCP server for AI agents (concat --mcp, set up) and a JSON-RPC API for scripts, so they can cut video with it too.

No endorsements yetNo verified confirmations yet — be the first.
Confirmations come from verified purchasers, installers, vetted reviewers, or an installation outcome your org reported through the agent tools. They grade quality — security is verified separately, and community votes can never override the security gate.

04Trust Passport
Full passport →0/0 automated components pass. An automated score is never a security guarantee.
This listing is unclaimed, so publisher identity cannot be verified and it stays below the “verified” tier by design — that is a statement about the listing, not about the project’s quality. Our automated scans still ran; a maintainer who claims it unlocks identity verification.
