Open-source alternatives to Xero
Xero is a cloud accounting for small businesses with AI assistance. If you would rather own the software, keep data on your own server or avoid per-seat pricing, these open-source tools tackle the same problem: run your books. Bookkeeping is where small businesses lose evenings. AI now handles the data entry; you keep the judgment.

Hosted vs open source: what changes
Open source swaps a subscription for setup time. Xero is hosted, supported and updated for you; with the tools below you (or someone you hire) install, update, back up and secure them. 0 of the 5 with a setup rating here need a developer. Most can also be bought as a hosted cloud plan from the same maintainers, which is a good middle path. Check each licence before you build on it.
