Rapla vs Tempus Resource

Rapla is an open-source system for scheduling resources and planning events, including rooms, people, and equipment. Its calendars offer month, week, day, and specialized views, with repeating appointments and conflict checks before saving. Administrators can define resource, person, and event types, assign categories and attributes, and set fine-grained permissions. Rapla exports to PDF and iCal and can email users when a resource is allocated. Data can be stored in a file or in MySQL, PostgreSQL, or HSQLDB. Rapla 2 is labeled stable and can run as a standalone application or in client-server mode; its desktop client supports Linux, Windows, and macOS using Java and OpenWebStart. The interface is available in English and German, with translations of varying completeness in French, Dutch, Polish, Spanish, Finnish, Brazilian Portuguese, and Czech. Rapla 3 describes Exchange sync, a GraphQL API, OAuth 2.0 with PKCE, and sign-in with Microsoft, Google, or Keycloak. Its nightly builds are self-signed, untested, and not for production. The software is free under AGPL-3.0-or-later or Apache-2.0.
