Overview:
Cap is an open-source screen recording tool designed as an alternative to Loom. It enables users to capture their screen, camera, and microphone, then share the recording via an instant link or export it as a finished video. Built for teams and individuals who want to own their data, Cap offers both a fast "Instant Mode" for quick feedback and a "Studio Mode" for creating polished recordings with editing features. It runs on macOS and Windows, with a web dashboard for managing recordings.
Core Features:
Recording Modes: Two distinct workflows are available: Instant Mode uploads and generates a share link during recording for speed, while Studio Mode records locally and opens an editor for background, zoom, trimming, captions, and export controls.
Data Ownership & Self-Hosting: Users can store recordings on Cap Cloud, connect an S3-compatible bucket (e.g., AWS S3, Cloudflare R2, MinIO), or self-host the full platform (web app, API, database, media server) using Docker Compose.
Async Collaboration: Recordings support comments, reactions, transcripts, viewer analytics, and team workspaces to keep feedback attached to the video.
Cap AI: Automatically generates titles, summaries, clickable chapters, captions, and transcripts for recordings.
Desktop Apps: Native desktop applications are available for macOS and Windows, which can be pointed at a self-hosted instance.
Loom Import: Users can import existing Loom videos directly into Cap.
Use Cases:
Creating bug reports: Developers can record their screen to show a bug, share a link, and collect comments or reactions from the team.
Delivering product demos or tutorials: Teams can use Studio Mode to record a polished walkthrough with captions and chapters for client work or launches.
Conducting asynchronous standups: Team members can record a quick update in Instant Mode and share the link to keep everyone informed without scheduling a meeting.
Managing a private video library: Organizations with data control requirements can self-host the platform and store recordings on their own S3-compatible storage or keep them local.
Why It Matters:
Cap provides a transparent, self-hostable screen recording workflow as an open-source alternative to Loom. The README emphasizes data ownership by supporting custom S3 storage, self-hosting via Docker Compose, and the ability to serve share pages from a custom domain. The project explicitly supports migrating from Loom, making it a practical choice for teams evaluating a switch to a platform where they control the infrastructure and recording data. Features like Instant Mode ensure the tool remains fast for ad-hoc sharing.
