VidStudio bets on browser-local video editing: Show HN 301 pts, free
A solo dev's browser editor runs FFmpeg in WebAssembly so footage never leaves the device — no upload, no account, free; Show HN drew 301 points.
VidStudio
What the business is
VidStudio is a free browser-based multi-track video editor: WebCodecs decodes frames (using hardware decoders where available), FFmpeg compiled to WebAssembly encodes and converts, and Pixi.js renders on a WebGL canvas. Files are read locally, projects persist in IndexedDB, heavy processing runs in Web Workers, and exports are written back to the device as MP4 (H.264/AAC) — no upload, no account, no watermark. It runs in Chrome, Edge, Firefox and Safari, works on mobile, and is paired with sibling tools such as compression and captioning pages.
How it started
The developer (HN: kolx) first posted a browser video-processing tool on 2026-02-10, explaining in that post that the hard part — FFmpeg WASM commands that hang — was solved by controlling how many threads FFmpeg uses at each stage; it drew 2 points. He returned on 2026-04-21 with the full multi-track editor pitched on no-upload and no-account.
What happened
The April Show HN hit the front page with 301 points and 109 comments, and Korben covered it the same day, praising an interface 'that looks like a real editing application' while flagging honest limits: HEVC struggles on Firefox, 10-bit video is unreliable on Windows, and some WEBM files with exotic audio codecs won't load.
How it ended up
Still live and free as of 2026-09-04: no account, no upload, no watermark; the FAQ keeps the core editing flow free and says future features for regulated industries may sit behind a paid tier.
Background
VidStudio is a free, browser-based multi-track video editor that runs entirely client-side: WebCodecs decodes frames on hardware decoders when available, FFmpeg compiled to WebAssembly handles encode and conversion, and Pixi.js renders on a WebGL canvas with a software fallback. Files are read locally, projects persist in IndexedDB, heavy work runs in Web Workers, and exports are saved back to the device as MP4 — no upload, no account, no watermark.
The developer (HN: kolx) first posted a browser video-processing tool in February 2026 (2 points), explaining that the fix for hanging FFmpeg WASM jobs was controlling thread counts per pipeline stage. He returned on 2026-04-21 with the full editor — 'a browser based video editor that doesn't upload your files' — which drew 301 points and 109 comments.
Korben featured the editor the same day, calling it a privacy step up from Clipchamp and Canva, praising its real-editor interface and mobile support, and listing limits (HEVC on Firefox, 10-bit on Windows). As of 2026-09-04 the editor is still live and free, with the FAQ keeping the core flow free and leaving paid features to a future regulated-industries tier.
What has to be true
- The no-upload claim is verifiable: the site tells users to watch the Network tab during export, turning a privacy promise into a testable fact.
- Browser-local removes install and app-store friction while keeping a real multi-track editing UI.
- Korben's same-day feature shows the wedge travels even in translation: privacy and no-account are universal selling points.
- Free with no watermark undercuts CapCut-style pricing anxiety for exactly the users who care most about their footage.
What can be applied
After a 2-point first launch, VidStudio came back as a full editor pitched on 'no upload, no account' — a claim reviewers could verify — and drew 301 points; the privacy framing made the difference.
Aftermath
As of 2026-09-04 VidStudio is live and fully free: no account, no upload, no watermark, MP4 export; the FAQ keeps the core flow free and puts any future paid tier behind regulated-industry features. Korben's 2026-04-21 review called it a clear privacy step up from Clipchamp/Canva and preferred it to Cutia for general users, while noting limits: HEVC struggles on Firefox, 10-bit video is unreliable on Windows, and some WEBM files refuse to load. Projects live in IndexedDB scoped to the browser profile, so switching laptops means starting over — a no-server tradeoff.
