What you may give up

No paid-feature limits established for this edition.

Keila Cloud starts at EUR 8/month for 2,000 emails, with unlimited contacts/projects. Self-hosting needs server/PostgreSQL and SMTP or another email transport service. These service costs are not feature locks.

Tier A: Official site explicitly excludes proprietary premium features; cloud and self-hosted use the same software. All hosted plans include all features. License source
