Problem solved
Cal.diy solves the problem of needing a fully open-source, self-hosted scheduling platform without proprietary enterprise features or license keys. It provides a community-maintained alternative to Cal.com for personal and non-production use.
Deployment reality
The available setup signal starts with: git clone https://github.com/calcom/cal.diy.git && cd cal.diy && yarn. Treat this as a starting point, then ask Codex or Claude to inspect the README, environment variables, runtime version, and deployment target before production use.
Commercial use
The recorded license is MIT. This is a useful commercial-use signal, but teams should still verify license text, dependencies, model/API terms, and trademark constraints.
Capability ceiling
calcom/cal.diy still needs a clearer capability analysis. Use the metadata as a discovery signal, not as a production recommendation.
Git-Stars is independent and not affiliated with GitHub or this project. Analysis may be AI-assisted and based on public repository metadata plus short README-derived summaries. We do not mirror full README files, docs, issues, or social comments.
calcom/cal.diy is tracked as a TypeScript project in the UI Framework, Infrastructure area. This evaluation combines public GitHub metadata, category signals, short source summaries, and Git-Stars editorial rules rather than copying project documentation.
Momentum check: the repository has 48k total stars, with +38 today, +0 this week, and +0 this month. These growth windows help distinguish durable adoption from short-lived visibility spikes.
Maintenance check: current activity is Active; the latest push was 14 days ago, and the open issue queue is 1.4k, about 2.97% of total stars. Treat this as an adoption signal, not a substitute for engineering due diligence.
Adoption check: 15k forks and 48k watchers suggest how often the project is reused or followed. License signal: MIT. Always verify license compatibility before commercial or internal use.
Practical fit: this project is most relevant when you need TypeScript teams evaluating ecosystem-native tooling. Be cautious when you need a legal review, security audit, or production SLA.
Source check: Git-Stars currently has 2 explicit source reference(s) for this report and a recent growth signal of 96. Follow the original GitHub repository for final install, security, and release information.
