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 — with 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.
