Open Source Screen Recorder — Free, Private, and Community-Built
Cap is the leading open-source screen recorder for Mac and Windows. Audit the code, self-host your recordings, and stay in full control of your data. Free forever with no vendor lock-in.
Why Choose an Open Source Screen Recorder
Open source means full transparency, real privacy, and the freedom to use Cap exactly how you want — without compromise
Fully Open Source on GitHub
Cap's entire codebase is publicly available and MIT-licensed on GitHub. Inspect every line of code, understand exactly what happens to your recordings, and contribute features or fixes back to the community.
Self-Host Your Recordings
Connect Cap to any S3-compatible storage — AWS S3, Cloudflare R2, Backblaze, or your own MinIO instance. Your recordings never touch Cap's servers unless you want them to. True data ownership.
No Vendor Lock-In
With a closed-source tool, you're dependent on a company's pricing, policies, and survival. Cap is open source — fork it, modify it, or self-host the entire platform. Your workflow is never held hostage.
Community-Driven Development
Cap is built in the open with contributions from developers around the world. Features are shaped by real user needs, not quarterly revenue targets. File an issue, submit a PR, or join the discussion on GitHub.
Privacy-First Architecture
Because Cap is open source, privacy isn't a marketing claim — it's verifiable. Review the data handling code yourself, run the app locally, and configure storage to keep recordings entirely within your infrastructure.
4K Recording at 60fps
Open source doesn't mean underpowered. Cap captures your screen at up to 4K resolution and 60 frames per second with system audio and webcam overlay. Professional-grade output at zero cost.
Instant Shareable Links
Stop recording and Cap generates a shareable link immediately. No manual uploading, no processing queue. Paste the link in Slack, email, or any tool and viewers get instant access.
AI Captions Without Compromise
Automatically generate accurate captions from your screen recordings. The AI pipeline is part of the open-source codebase — you can see exactly how transcription works and run it on your own infrastructure.

How Cap Stands Apart as an Open Source Screen Recorder
The open-source difference goes beyond price — it's about trust, control, and long-term sustainability
Cap vs Loom
Loom is a closed-source SaaS that owns your recording data and can change pricing at any time. Cap is open source with custom storage support, starting at $9.99/month versus Loom's $18/month — and Cap's Studio Mode is completely free. See the full Cap vs Loom comparison.
Cap vs OBS Studio
OBS is also open source but built for live streaming, not async screen sharing. Cap brings the open-source ethos to everyday recording with instant shareable links, cloud storage, and built-in commenting — features OBS doesn't offer.
Cap vs Vidyard
Vidyard is a closed-source enterprise video platform with pricing to match. Cap gives teams the same async video capabilities with full transparency, no vendor lock-in, and a free tier that covers most use cases.
Cap vs Camtasia
Camtasia is a powerful but closed-source editor costing $299.99. Cap is open source and covers the full recording-to-sharing workflow for free. If you need advanced editing, combine Cap's free recording with your editor of choice.
Two Open Source Recording Modes
Cap gives you two distinct modes so you can choose the right workflow for every recording
Instant Mode
Record and share instantly with a link ready the moment you stop. Perfect for bug reports, async updates, and quick team communication. Free plan includes recordings up to 5 minutes with built-in thread commenting.
Studio Mode
Completely free for personal use with no time limits. Records at full quality up to 4K with separate screen and webcam tracks. Ideal for tutorials, product demos, and training content — no subscription required.
