Why it matters

We look beyond stars: what problem it solves, whether it creates real utility, and what makes its approach worth noticing.

Last 90 days

Problem

Provides a fully open-source and restriction-free scheduling platform code for self-hosted individual use.

Practical value

Strips commercial enterprise features under pure MIT license with clear local setup and Docker quickstart.

Innovation / differentiation

Essentially a de-commercialized community fork of Cal.com, using standard Next.js and Prisma stack.

Leverage potential

Depends on Node.js and PostgreSQL, requiring self-managed security and config, demanding server admin skills.

Why now

Meets the demand for purely open-source personal scheduling alternatives as commercial options restrict features.

Community activity

In the last 90 days there were 133 new issues and 436 pull requests; the bounded issue/PR samples include 70 issue authors and 46 PR contributors, with at least 0 releases.

Maintainer responsiveness

The 100-issue window sample had a 21% close rate, and the 95-pull-request sample had a 6% merge rate. Maintainer-response observations covered 30% of that issue sample, with a 3% response rate and median first response of 21.7 hours.

Key highlights

  • Create and manage self-hosted booking pages and schedules
  • Store booking, user, and configuration data in PostgreSQL
  • Run through Docker Compose or the documented local development workflow

Quick start

How it is installed, how hard it is, and where to start.

Where it runs

Self-hosted (your own server)

Difficulty

Harder — CLI / server skills help

Docker supportedSelf-hostableRuns locally
  1. 01Prepare PostgreSQL and configure the database URL plus the two required random secrets from .env.example.
  2. 02Prefer the documented Docker Compose path, or install dependencies, run database migrations, and start the development server.
  3. 03Create booking types after first-user setup; before using real business data, reassess the project’s explicit non-production warning.

Best for

  • Teams that want data on their own servers
  • Developers who want to try it on their machine
  • People who prefer Docker deploys

More about it

Cal.diy is a community fork of Cal.com with the enterprise and commercial code removed, and the repository is MIT-licensed. It is aimed at individuals who want to control their own scheduling stack, with web booking pages, PostgreSQL, and Docker Compose deployment. The README explicitly recommends personal, non-production use, so commercial or enterprise production deployments should be evaluated against Cal.com or another production-ready option instead.
