Overview
Indico is a full-featured conference and meeting management system developed at CERN and widely adopted by scientific institutions. It handles abstract submission, paper review, scheduling of multi-track programs, room booking, registration, and participant management. Trusted by large-scale international events, it is mature, actively maintained, and ships as a Docker image.
Where it falls short of Calendly
- Overpowered for simple one-on-one appointment booking
- Setup involves multiple services (Redis, PostgreSQL, Celery) and is complex
- UI design is functional but dated compared to modern booking tools
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
