One Rec vs Cap
Cap is a lean open-source recorder built in Rust and Tauri, with both instant-share and local Studio modes. One Rec stays close on recording quality and adds a deeper multi-track timeline editor, cinematic auto-zoom, custom backgrounds with motion blur, and a full live streaming studio — on Linux too.
One Rec vs Cap: Cap is the best pure open-source alternative to Loom with a lightweight Rust/Tauri architecture and self-hostable cloud. One Rec has a more developed editor, cinematic zoom polish, and a live streaming studio, plus native Linux support — at the cost of not being fully open-source.
Quick verdict
- Both have free tiers. One Rec adds a multi-track timeline editor and a live streaming studio Cap doesn't have.
- One Rec runs natively on macOS, Windows, and Linux. Cap ships native apps for macOS and Windows only — Linux is self-hosted server via Docker.
- Cap is fully open-source (MIT capture crates + AGPLv3 rest). One Rec is source-available under a fair-use license.
- Cap has AI-generated titles, summaries, chapters, and transcripts. One Rec has local Whisper captions but not auto-summaries.
How they compare
Verified feature-by-feature breakdown of One Rec vs Cap.
Where One Rec wins
Deeper editor with cinematic polish
One Rec's timeline is multi-track with non-destructive clip trimming, segment reordering, zoom keyframe tuning, cursor effects, motion blur, and device frames. Cap's editor focuses on basic trims and layout — the recording is the product.
Native Linux desktop app
One Rec ships a real Linux build with ScreenCaptureKit-equivalent quality. Cap's desktop clients are macOS and Windows only; Linux users can self-host Cap's server via Docker but there's no native desktop recorder.
Live streaming studio included
One Rec is also a streaming studio — scene management, source layering, guest invites, and multi-destination RTMP to YouTube, Twitch, LinkedIn, custom endpoints. Cap covers recording and sharing, not going live.
When Cap might be a better fit
We believe in honesty. Here's where Cap might actually suit you better.
You need fully open-source software
Cap is MIT for capture crates and AGPLv3 for the rest. If open-source licensing is a hard requirement (legal, audit, philosophy), Cap matches that and One Rec doesn't.
You want to self-host video sharing infrastructure
Cap's cloud component is Dockerized. You can run your own Cap instance, BYO S3 storage, add a custom domain, and keep the entire pipeline inside your infrastructure. One Rec's cloud sharing is hosted only.
AI summaries and threaded comments are core to your workflow
Every Cap recording auto-generates a title, summary, chapters, and transcript, with threaded comments directly on the shared video. If your team needs that as a baseline, Cap has it out of the box.
You prefer Rust/Tauri lightness over Electron
Cap is built on Rust and Tauri, launches fast, and has a small binary footprint. One Rec is Electron and heavier on RAM. If you care about lean resource usage, Cap's architecture wins that axis.
Which one should you pick?
A quick cheat sheet — pick the column that sounds most like you.
Pick One Rec if…
- You want cinematic auto-zoom, cursor effects, and motion blur for demos
- You're on Linux, or your team does
- You want a multi-track timeline editor, not just trim-and-share
- You stream live and want a studio in the same app
- You don't need open-source — you want the better editor
Pick Cap if…
- Open-source licensing is a hard requirement
- You want to self-host the entire video-sharing stack with your own S3
- AI auto-summaries and threaded comments on videos are load-bearing for your workflow
- You prefer Rust/Tauri's lightweight footprint over Electron
- Instant-share-link mode (upload-while-recording) is your primary flow
