Jami vs Keybase

Jami is free/libre software for private messaging and calls, with end-to-end encrypted communications and peer-to-peer connections. It offers instant messaging, audio and video calls, group chats, and recorded audio and video messages. Users can hold video conferences and create rendezvous points without third-party hosting, as well as share files or screens and stream media. Jami says it does not require a server to relay data between users; it also states that communications use perfect forward secrecy and comply with the X.509 standard. One account can link multiple devices, and account creation does not require personal information. Jami can also function as a regular SIP client. Optional extensions include green screen, watermark, auto answer, local AI transcription, audio filter, and video segmentation. These extensions are unavailable to iOS users, and features vary by client. Platforms listed include Android, iOS, Linux, macOS, web, and Windows, along with API and extension access. Jami also provides an OpenClaw channel plugin; bot accounts and API access are supported on desktop Linux, macOS, and Windows. The project is led by Savoir-faire Linux Inc. and supported by a global community of free software contributors.

Keybase is a free messaging and file-sharing product for Android, iOS, Linux, macOS, web and Windows. It uses public-key cryptography for private chats and says messages and files are end-to-end encrypted so only users and intended recipients can read them. Private keys stay on users’ devices rather than Keybase’s servers. Users can set timers on sensitive messages in one-to-one chats and team, group and community channels. Teams bring together private chats with multiple channels, file sharing and collaboration on Git. Team chats, files and Git are end-to-end encrypted, and team keys change when someone is removed or revokes a device. Teams and subteams can store up to 100 GB of documents, photos and videos; personal Git repositories have a combined 100 GB limit, and each team gets 100 GB for Git. Keybase also supports public communities and identity proofs involving integrated social networks. The download page describes it as open source, and business admin controls are available. For client bugs, Keybase directs users to run `keybase log send` in a terminal and follow the instructions.
