Open-source Booksy alternatives

Cal.diy is a community edition of Cal.com, the scheduling platform, released as open source. It is a fork with all enterprise and commercial code removed, and the whole codebase is licensed under MIT with no proprietary Enterprise Edition split. It is built with TypeScript, Next.js, tRPC, Tailwind CSS and PostgreSQL through Prisma.

Compared with Cal.com, it drops enterprise features such as Teams, Organizations, Insights, Workflows and SSO/SAML, and it needs no license key or Cal.com account. Contributions go directly into this community-maintained project. No hosted service exists, so you run it yourself on infrastructure you control.

The maintainers warn that it is intended for personal, non-production use and that running it yourself demands solid skills in server administration, databases and protecting sensitive data. For commercial or enterprise needs they point to Cal.com instead. Cal.diy suits individuals and tinkerers who want complete control over their own scheduling setup.

Easy!Appointments is an open-source appointment scheduling system that lets you run your own booking workflow. It is self-hosted, so your data stays under your control, and it can be customized and integrated with an existing website and database.

Features include appointment and customer management, organization of services and providers, working plans and booking rules, Google Calendar synchronization, an email notification system and a multi-language interface. Topics on the repository also point to a REST API for integrations.

Production installs need Apache or Nginx, PHP 8.2 or later and a MySQL database: upload the files, create the database, copy config-sample.php to config.php and update the settings. A Docker Compose environment is provided for development. It is licensed under GPL-3.0, free for personal and commercial use, with premium features and professional services offered separately.
