Beancount.io

Pricing for Beancount.io is not something you need to work out before you start reading, because the more useful question is how it keeps your books.

The platform is a plain-text accounting service built on double-entry bookkeeping, and every transaction lives in a text file under Git version control, so each change to your finances is tracked the way a code change would be.

Beancount.io adds AI-assisted bookkeeping on top.

It categorizes transactions automatically and flags anomalies, and you can script your own reports and reconciliations.

Because the data stays in plain text, you can read it, audit it and move it elsewhere without vendor lock-in.

You get a web and mobile interface, though the workflow still suits people comfortable with the command line.

It is built for developers and finance professionals who want their accounts to behave like a codebase.
