Nextcloud Talk vs Proton Meet

Nextcloud Talk combines meetings, chat, and webinars in a self-hosted communication service. It supports private, group, and public calls, URL invitations for external participants, and chat that remains after calls. Users can share Nextcloud Files documents and connect rooms with files, calendars, and tasks. Federation links chats and calls across Nextcloud servers, while bridges connect services such as Slack, Microsoft Teams, Matrix, IRC, Mattermost, and XMPP. Talk runs in browsers and on Windows, macOS, Linux, iOS, and Android, with a public API for app integrations. Security features listed include end-to-end encrypted calls, layered encryption, brute-force protection, suspicious-login detection, and a $10,000 bug bounty. Typical private deployments handle 6–10 participants, or up to 20 without video. Webinars, lobby-based public video conferences, SIP dial-in, and larger calls require the High Performance Backend.

Proton Meet provides private video conferencing for teams, friends, and family, with apps for the web, Windows, macOS, Linux, iOS, and Android. It uses Messaging Layer Security to encrypt audio, video, screen shares, and chats end to end. External guests can join through a meeting link without a Proton account. Hosts can blur backgrounds, reduce noise, lock meetings, block new arrivals, mute audio, stop video, and remove attendees. Meet integrates with Proton Calendar for calls and appointment scheduling. Proton says its apps are fully open source for independent auditing and that it does not retain meeting passwords, audio, video, chat messages, or metadata linking participants after a call. The free plan is free, billed $0.00 every month, with meetings up to 60 minutes, 50 participants, and five meeting links per day. Paid pricing starts at $7.99/user/mo (annual). The Professional plan lists meetings up to 24 hours and 100 participants, plus screen sharing, chat, scheduling, and recording. Proton also states that Meet complies with GDPR, HIPAA, CJIS, and PCI.
