OpenTalk vs TrueConf

OpenTalk is a browser-based video conferencing service available as a hosted service or for installation in a customer's data center. It runs in common browsers without local software, although Safari on Apple devices has functional limitations. Meetings can use breakout rooms and sub-room conversations, with multiple moderators, a whiteboard, meeting minutes, polls and surveys. Open and secret voting are supported, with results documented. Participants can join by phone for audio-only access, and OpenTalk can connect to in-house phone systems or external SIP providers. Open APIs support integrations, and Keycloak is an identified single sign-on option. Its on-premises APIs cover user and room provisioning, configuration, metrics and reporting. OpenTalk describes itself as open source and GDPR-compliant, and reports receiving the German Federal Office for Information Security IT security label for video conferencing services. Starter is free, with up to five participants and 30-minute calls, but no recording. Standard is $7.50 a month per user, excluding VAT; Premium is $12.50 a month per user, excluding VAT. Both paid plans include recording.

TrueConf Server combines video meetings, messaging, webinars, and remote collaboration in a self-hosted platform. Organizations can run it on premises inside a corporate network, including without an internet connection. Eligible licenses support conferences with up to 2,000 participants; the perpetual Free edition allows up to 10 participants, 1,000 messaging users, one guest connection, and one SIP/H.323 connection. Collaboration tools include chats, file and content sharing, recording, polls, reactions, and conference scheduling. Listed integrations include Active Directory and LDAP, SSO, SIP/H.323 systems, corporate calendars, APIs, and SDKs. The service can connect to SIP PBXs so users can call PBX subscribers from its client applications. Described AI features include noise reduction, background blurring or replacement, and meeting transcription and summaries. TrueConf lists MFA and trusted zones, as well as DLP integration for Enterprise. The free plan is perpetual; the paid TrueConf Server plan is $10 per user per year. Basic, extended, and full support packages vary in response times and coverage; basic support excludes assistance with AD/LDAP integration, the API, and port configuration. Client platforms include web, Windows, macOS, Linux, iOS, and Android.
