Someday

Free, self-hostable meeting scheduler built on Google Apps Script — a Cal.com and Calendly alternative for Gmail users.

Open source alternative to:

Someday is a free, open source scheduling app that runs entirely on Google Apps Script. It is a lightweight alternative to Calendly and Cal.com for solo workers, freelancers, and small teams who live in Gmail and Google Calendar.

Users share a personal booking page that lets invitees pick an available slot, and the event is created on Google Calendar automatically. Because it runs inside Google’s infrastructure, there is no server to host and no database to maintain, which makes it one of the lowest-effort self-hostable schedulers available.

Someday is built with React, TypeScript, Vite, and shadcn/ui, and is released under MIT. It is a strong fit when you want a clean, dependency-free booking flow for one-on-one and small-group meetings without paying for Calendly Pro.
