One Rec vs Cap
Cap is a lean open-source recorder built in Rust and Tauri, with instant-share and local Studio modes. One Rec adds a timeline editor with auto-zoom, cursor smoothing, backgrounds and camera layouts, plus a live streaming studio (in alpha). It runs on Linux (X11) too.
Short answer
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, auto-zoom, a live streaming studio, and a Linux desktop app. The tradeoff is that One Rec isn't fully open-source.
TL;DR
Quick verdict
- Both have free tiers. One Rec adds a timeline editor with auto-zoom and a live streaming studio Cap doesn't have.
- One Rec has desktop apps for macOS, Windows, and Linux (X11). Cap ships native apps for macOS and Windows only. On Linux, Cap is a 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.

One Rec strengths
Where One Rec wins
A deeper editor
One Rec's timeline holds zoom, trim, annotation, mask and camera layout regions over your recording, with editable auto-zoom, cursor smoothing, click effects and motion blur. Cap's editor focuses on basic trims and layout.
A Linux desktop app
One Rec ships a Linux build (AppImage, .deb or .rpm) that records on X11. Cap's desktop clients are macOS and Windows only; Linux users can self-host Cap's server via Docker but there's no desktop recorder.
Live streaming studio included
One Rec also has a streaming studio (in alpha), with scenes, guest invites on Creator and up, and multi-destination RTMP to YouTube, Twitch, Facebook and custom servers, capped by plan. Cap covers recording and sharing only.
Honest take
When Cap might be a better fit
Here's where Cap might 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.
Decision helper
Which one should you pick?
Pick the column that sounds most like you.
Pick One Rec if…
- You want auto-zoom, cursor effects, and motion blur for demos
- You're on Linux (X11), or your team is
- You want a timeline editor, more than trim-and-share
- You stream live and want a studio in the same app
- You don't need open-source and 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

FAQ
Frequently asked questions
No. Cap is dual-licensed MIT (capture crates) + AGPLv3 (app). One Rec is source-available under a fair-use license that permits free personal and commercial use, but isn't OSI-approved open-source. If that distinction matters for your project, Cap is the option that matches.
The desktop recorder apps ship for macOS and Windows only. Cap's server component is Dockerized and you can self-host the sharing infrastructure on any Linux box, but there's no Linux desktop recorder. One Rec has a Linux desktop app that records on X11; Wayland isn't supported yet.
Different tradeoffs. One Rec runs Whisper on your computer in 17 languages, offline after a one-time model download. Cap's AI features (titles, summaries, chapters, transcripts) run against a cloud service, cover more languages, and add auto-summaries that One Rec doesn't generate. Privacy goes to One Rec; richer AI output goes to Cap.
Not as a primary mode. One Rec records to local files first; you can then share via the shared-video feature (3 on Free, up to 500 on Team). Cap's Instant Mode uploads as you record and gives you a link the moment you stop. The tradeoff is latency vs quality.
No. Cap is a recording-and-sharing tool. One Rec includes a streaming studio (in alpha) with scenes, guest invites on Creator and up, and multi-destination RTMP output: 1 destination on Free, up to 25 on Team.
