Appointments for Nextcloud vs Rallly
Both are free/open-source alternatives to Calendly. Here's how they stack up — verified facts, no spin.
Appointments for Nextcloud
Calendly-style booking pages built into your existing Nextcloud.
Appointments is a Nextcloud app that adds Calendly-style public booking pages on top of a Nextcloud instance's own calendar (CalDAV-compatible, so it also works with iOS, Android, and Google Calendar via sync). It's the natural fit for anyone already self-hosting Nextcloud who wants booking pages without adding a second standalone app to operate.
Rallly
Open-source group scheduling and meeting-time polling.
Rallly solves a different but related problem: instead of one person publishing a booking link, it lets a group vote on the best time for a meeting across several proposed slots — the open-source answer to Doodle that also covers a chunk of Calendly's group-scheduling use case. It's actively developed and offers a hosted version (rallly.co) alongside a documented self-hosted Docker deployment.

Appointments for Nextcloud edges it on the Sovereignty Score, but the right pick depends on the trade-offs below.
Appointments for Nextcloud
Strengths
- +Actively maintained (updated within the last two weeks) with very positive community ratings on the Nextcloud App Store
- +No new infrastructure if you already run Nextcloud — one more app, not a second server to maintain
- +Standard CalDAV underpinnings mean no lock-in to a proprietary calendar format
- +Supports GDPR-relevant features like embeddable request forms and up to 10 booking pages per user
Trade-offs
- −Only useful if you're already running (or willing to run) Nextcloud — it's not a standalone product
- −Maintained largely by one developer; bus-factor risk is higher than a larger team project
- −No built-in payment collection, unlike Calendly's paid tiers or Easy!Appointments' add-ons
- −Nextcloud itself can be heavier to operate than a single-purpose scheduling app
Rallly
Strengths
- +Simple, focused tool that's genuinely good at the group-availability-poll problem
- +Active project (5,100+ stars, commits within the last day) with a documented Docker Compose deployment
- +AGPL-3.0 keeps improvements to a hosted fork open
Trade-offs
- −Not a 1:1 booking-page replacement — no per-provider service catalog, payments, or staff management like Calendly/Easy!Appointments
- −Primary distribution is the hosted rallly.co app; self-hosting is supported but secondary in the project's own messaging
- −AGPL-3.0 requires you to publish modifications if you offer a modified version as a network service
