Cap

Cap is a beautiful, open-source screen recorder that lets creators and engineering teams capture screen and webcam in 4K, edit locally, and share instantly through short links, while keeping full ownership of the raw files and hosting. It positions itself as a privacy-respecting Loom and Camtasia alternative for people who want their recordings to stay under their control.

The app ships with three recording modes: Instant for quick Loom-style share links, Studio for timeline editing with backgrounds, padding, rounded corners, and annotations, and screenshot capture for stills. AI features auto-generate titles, summaries, chapters, and transcripts, while custom S3 buckets and custom domains let teams host recordings on their own infrastructure.

Key benefits:

• Open-source core on GitHub gives full transparency and community contributions
• 4K/60fps recording with intelligent compression keeps file sizes manageable
• Custom S3 and domains let teams host videos on their own storage and brand
• Local, cloud, or self-hosted storage options fit any privacy requirement
• AI titles, summaries, chapters extract structure from every recording automatically
• Native apps for macOS and Windows with Apple Silicon optimisation

Cap is developed in the United Kingdom with GDPR-aligned data handling and an option to host recordings entirely on customer-owned storage, keeping data out of US cloud jurisdiction. Self-hosted deployments give complete sovereignty over video assets and viewer analytics.

Ideal for engineers, support teams, and content creators who want a polished screen recorder with local-first storage, open-source transparency, and a clean alternative to proprietary tools like Loom and Camtasia.
