Built To Be Yours
Every feature respects how you actually work — your storage, your platform, your workflow. No vendor lock-in, no compromises.
Bring Your Own Storage
Plug in your own S3 bucket, route to Cap Cloud, or keep recordings entirely local. Your videos, your bucket, your bill — no vendor lock-in, ever.
Cap AI Does The Busywork
Every recording gets an AI-generated title, summary, clickable chapters, and a fully searchable transcript — so the work after the recording is already done.
Async Conversations That Move
Threaded comments, emoji reactions, and viewer analytics turn one-way videos into two-way conversations. Replace the standing meeting for good.
Native, Not An Electron Tab
Built on Tauri and Rust for genuinely native performance on macOS and Windows. No bloated browser, no battery hit — just a fast, lightweight recorder.
Open Source, End To End
Inspect every line, contribute the feature you've been waiting for, or self-host the entire stack. Fair, transparent, and yours to fork.
Pixel-Perfect Capture
Record up to 4K at 60fps with hardware-accelerated encoding. Crisp text, smooth motion, sane file sizes — the quality your work deserves.
Loved By Builders, Trusted By Teams
Join thousands who've made Cap their daily driver for visual communication.

I've been testing Cap.so for no other reason than some old habits die hard for this former software analyst. Whew that UI is so polished and crispy. Between the open source code, self hosted vids, editing features and price point -- gone give Loom some competition 🤞🏽

Tried @Cap v 0.3.beta and found an issue while exporting video. Wrote to @richiemcilroy about the problem and ~40 mins later the issue is fixed. I'm sold. Checkout Cap.so

No brainer instant purchase this morning: was looking for a solid screen recorder, for my new MacBook Pro, gave @cap a try, got myself a license within 10 mins — flawless UX sometimes speaks louder than lengthy marketer's words !

I've been looking for *ages* for a screen recording app that does the job + allows to zoom in/out easily and @Cap is AWESOME! Free, cross-platform, fully-featured, open-source. I mean...unless you love spending +$200 for recording your screen, use Cap!
