Our verdict on Keybase
Keybase combines encrypted file storage, secure messaging, identity management, and team collaboration in one open-source application. It suits individuals and teams that need private file exchange without a subscription, especially when encrypted team folders, role-based permissions, and communication tools matter. Files can be stored in private, public, or team folders, while access is managed through Keybase identities and device keys.
Keybase is free for everyone, with a 250 GB individual storage limit and a 100 GB team storage limit. The same service is available through the web, macOS, Windows, Linux, iOS, and Android. Desktop users also get Finder and Windows Explorer integration, while offline folder synchronization supports access across supported devices. The platform covers file sharing with Keybase users, encrypted team chat, and Git collaboration, but it does not provide third-party integrations. That makes it a focused ecosystem for secure exchange rather than a broadly connected cloud storage hub.
Its strongest differentiator is the combination of end-to-end encrypted storage, cryptographic file signing, team folders, and built-in collaboration features. Teams can manage members, files, and subteams through role-based permissions, while private files remain tied to Keybase identities and device keys. The main trade-off is recovery: the historical file recovery window is two weeks, which may be short for teams needing longer retention. Choose Keybase for free encrypted sharing and focused team collaboration; consider another cloud storage service if broad integrations or longer recovery history are essential.
