Clapshot review
An open-source review workspace with strong annotation and versioning tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Clapshot is an open-source, self-hosted web application for collaborative review of video, audio, and images. It is designed for organizations that want to keep media on infrastructure they control rather than use commercial cloud services. Reviewers can work through a browser while the application runs with a Linux server, using Docker Compose or a Debian package for deployment. Windows, macOS, and Linux are supported as platforms, while mobile browser support is limited.
Its strongest area is review depth. Clapshot combines real-time synchronized playback with time-coded threaded comments, timeline pins, and drawing annotations that support undo and redo. Version sets help teams group and switch between media revisions, and subtitle tracks can be uploaded and synchronized. EDL imports become time-coded comments, while FFmpeg-based transcoding and thumbnail generation support media handling. These features make it a focused option for teams that need detailed, revision-aware feedback rather than simple video sharing.
Clapshot also fits technical environments with controlled access requirements. Hierarchical folders provide sharing and administration, and reverse-proxy authentication can integrate with OAuth, LDAP, Kerberos, and SAML. Slack is listed among its integrations. The trade-off is operational: teams must manage self-hosting, server deployment, authentication configuration, and administration themselves. Choose Clapshot when infrastructure control, open-source deployment, synchronized review, and versioned feedback matter most. Teams seeking a managed commercial service, stronger mobile support, or verified approval workflows should consider another option.
