Twake Calendar review
A flexible calendar for Twake users who want shared planning and deployment control.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Twake Calendar is an open-source calendar for teams and organizations that need shared scheduling, delegated calendar management, and control over deployment. It supports event creation, participant invitations, access-controlled shared calendars, availability sharing, booking workflows, time-zone coordination, and video meetings through Twake Visio. It can run as a standalone application or as part of Twake Workplace, making it a natural fit for organizations already considering the wider Twake suite.
The listed plans are broader Twake cloud and workplace offers. Discover is free and includes 5 GB of cloud storage, Instant Chat messaging, Advanced support, Collaborative notes, and unlimited authorized devices. Standard costs €4 per month and adds 50 GB of storage and an Office documents editor. Premium costs €12 per month and raises storage to 1000 GB while retaining the Office documents editor and the other listed features. For companies is an enterprise offer for businesses or local authorities. These tiers are relevant when calendar use sits alongside storage, messaging, notes, and document editing rather than as a Calendar-only purchase.
Twake Calendar’s ecosystem fit is strongest inside Twake: it integrates with Twake Mail, Chat, Drive, and Visio, while CalDAV synchronization, iCalendar import, and calendar export support existing calendar workflows. Cloud and self-hosted deployment options, GDPR coverage, and support through email and documentation suit organizations that want infrastructure control. Teams seeking a broad range of third-party integrations may prefer an alternative, while open-source workspace users needing shared calendars, booking, conferencing, and multi-platform access should consider Twake Calendar.
