how to choose a Teamwork alternative
Easiest to get running
Focalboard — a one-click install, no server to maintain.
Most proven
Plane, with 55,000 GitHub stars — the largest community of the 8, which usually means more answers when something breaks.
Works on your phone
ONLYOFFICE Groups has a mobile app on iOS and Android.
Needs real ops to self-host
Odoo Community, ONLYOFFICE Groups and OpenProject are capable but expect someone to run a server, updates and backups. Budget for that before choosing one.
what you give up by leaving Teamwork
- agency billing, workload, client permissions, integrations, and reporting
- deep integrations
- enterprise permissions
- large-scale reporting
- battle-tested notifications and mobile apps
None of the picks above covers all of it. The full verdict says which gaps matter.

why people still pay for Teamwork
People still pay for Teamwork because teams pay because project state has to remain authoritative through staff changes, outages, and years of accumulated workflow exceptions. The recurring cost buys auth, permissions, notifications, search, migrations, audit history, integrations, backups, and uptime, not just the visible interface. If none of that applies to you, any pick above saves $119.88 a year.
