Important: how close are they to Screen Studio?
Cap is the closest: its studio mode records up to 4K/60fps and includes auto-zoom, a built-in editor, backgrounds, and captions. OBS Studio, ShareX, Screenity, and Kap record the screen but do not generate Screen Studio's automatic zoom and cursor effects, so expect more manual editing for a polished result.
Platforms
OBS Studio and Cap run on Windows, macOS, and Linux. ShareX is Windows only, Kap is macOS only, and Screenity is a Chrome extension. Screen Studio itself is macOS, so Windows and Linux users will find the broadest choice in OBS Studio and Cap.
License details
OBS Studio is GPL-2.0, ShareX and Screenity are GPL-3.0, Kap is MIT, and Snapify is AGPL-3.0. Cap is AGPL-3.0 except its cap-camera and scap crates, which are MIT; its cloud and Pro plans are paid, while the code can be self-hosted.
Project maintenance
Kap has not had a release since 2022 and its last commit was in November 2024, and Snapify's last commit was in November 2024, so check that they still meet your needs. OBS Studio, ShareX, Screenity, and Cap are actively maintained.
Self-hosting and sharing
Cap can be self-hosted with Docker Compose, S3-compatible storage, and your own server URL, and Snapify is built around self-hosting shareable recordings. ShareX uploads to more than 80 destinations. OBS Studio, Screenity, and Kap save recordings locally.
