Akaunting

free self-hosted accounting software

Overview
Company	Akaunting
URL	akaunting.com
Pricing	free— Self-hosted is free (single user/accountant); Cloud-hosted plans $12-218/mo
License	open
Hosting	hybrid

Self-hostable double-entry accounting: invoicing, online payments, expense tracking, multi-currency, unlimited bank/cash accounts. The free self-hosted tier is limited to one user and one accountant -- fine for a single bookkeeper, not for a team that needs shared access.

Usage Notes

Even the self-hosted install requires an API key that calls home to Akaunting's servers to validate your license tier -- worth knowing if full data sovereignty (no external dependency at all) is a hard requirement, since this isn't quite that despite being open source.
