Both offer free plans for small teams. But one gives you Slack integration, a mobile app, API access, and real scalability. Here's the full comparison.
Choose Offly if: You want a free leave tracker that actually grows with you — with Slack/Teams integration, a native mobile app, API access, and professional features like audit trails and permissions.
Choose Leave Dates if:You have a very small team (under 5–10 people), don't use Slack or Teams, don't need a mobile app, and want the absolute cheapest option beyond the free tier.

The features that make the difference as your team grows.
Leave Dates has no chat integration. Offly syncs your team's leave status to Slack and Teams automatically.
Leave Dates is web-only. Offly has a native iOS and Android app with push notifications and biometric login.
Leave Dates has no API. Offly offers full REST API and webhooks for custom integrations and automation.
Leave Dates feels basic once you grow past 10 users. Offly's permissions, audit trail, and reporting scale smoothly.
Honestly — some teams are fine with Leave Dates.
If you have 3–5 people and just need a shared calendar to see who's off, Leave Dates covers that. You don't need integrations or automation at that scale.
If your team doesn't use Slack or Microsoft Teams, Offly's integration advantage doesn't apply. Leave Dates' calendar-focused approach may be sufficient.
At £1/user/month vs £1.50/user/month, Leave Dates saves 50p per user. For teams where every penny matters and features aren't a priority, that adds up.
Offly's free plan includes Slack integration, mobile app, and API access. Set up in under 5 minutes.
