# DayOtter

> DayOtter is the AI-native, open-source scheduling platform. Its assistant, Otter, books meetings, protects focus, and clears the scheduling back-and-forth - always confirm-first (it drafts, a human approves). Sync every calendar, run team round-robin and collective scheduling, accept payments, and self-host the whole thing under AGPLv3.

Key facts:
- Open-source (AGPLv3); self-hostable in one command; managed cloud at dayotter.com.
- A privacy-respecting alternative to Calendly, Cal.com, Motion, and Reclaim, and to manual Google Calendar back-and-forth.
- Otter (the AI) is confirm-first: it never changes a calendar on its own, it proposes an action the user approves.
- Free tier plus a $9/seat/month Pro plan on the cloud edition; all features are unlocked when self-hosted.

## Comparisons
- [DayOtter vs Calendly](https://dayotter.com/vs/calendly): The category default - polished, but a crippled free tier and no self-host.
- [DayOtter vs Cal.com](https://dayotter.com/vs/cal-com): Went closed-source in 2026, leaving a stripped MIT fork. DayOtter is the open alternative.
- [DayOtter vs Motion](https://dayotter.com/vs/motion): Powerful auto-scheduling - but pricey, desktop-first, and it reschedules you silently.
- [DayOtter vs Reclaim](https://dayotter.com/vs/reclaim): Great focus defense - but Google-only, and it doesn't do booking links or teams.
- [DayOtter vs Google Calendar](https://dayotter.com/vs/google-calendar): Where your events live - but its booking is bare-bones, with no team routing or AI.
- [DayOtter vs Acuity Scheduling](https://dayotter.com/vs/acuity): Deep appointment tooling for service businesses - but Squarespace-owned, paid-only, and no AI.
- [DayOtter vs SavvyCal](https://dayotter.com/vs/savvycal): A lovely booking experience - but solo-focused, paid-only, closed, and no AI.
- [DayOtter vs Doodle](https://dayotter.com/vs/doodle): The classic group poll - but ad-supported free, dated, and thin on real scheduling.
- [DayOtter vs YouCanBook.me](https://dayotter.com/vs/youcanbookme): Flexible booking customization - but fiddly, dated, and no team AI.
- [DayOtter vs Clockwise](https://dayotter.com/vs/clockwise): Smart focus-time defense for teams - but Google/Slack-bound, and it doesn't take bookings.
