1. Offly — Best Overall
From free · £1.50/user/mo for Pro
Offly is a purpose-built leave management platform designed for modern teams. It launched in 2025 and has quickly gained traction with UK SMEs who want something cleaner and more integrated than the established options.
Standout features:Automatic Slack status sync (your status updates to "On Holiday" when you're off), Microsoft Teams integration, real-time approval workflows, webhooks for custom automation, audit trail, and a genuinely modern interface.
Best for: Tech companies, remote teams, agencies, and any team that uses Slack or Teams daily. The free plan (up to 5 users) makes it accessible for startups.
Drawbacks:No Bradford Factor scoring. No built-in payroll or document management. It's a dedicated leave tracker, not a full HRIS.
