how to choose a Bonsai alternative
Easiest to get running
Dolibarr — a one-click install, no server to maintain.
Most proven
ERPNext, with 37,700 GitHub stars — the largest community of the 4, which usually means more answers when something breaks.
Needs real ops to self-host
ERPNext is capable but expects someone to run a server, updates and backups. Budget for that before choosing it.
what you give up by leaving Bonsai
- live bank feeds and payment rails
- tax and accounting rule updates
- audited security and recovery
- multi-user controls and accountant workflows
None of the picks above covers all of it. The full verdict says which gaps matter.
