Arca · self-hosted personal finance

Know what's safe to spend.

Arca is a calm personal finance app you run at home. One clear number for today, the bills still to come, and where your money went, all on your own server.

What Arca does for you

See where you stand

One calm number

Safe to spend is your budget minus what you’ve spent and the bills still to come. Home shows it first, with the sum underneath.

No busywork

Transactions come in by themselves

Connect your bank, or drop in a CSV export. Rules and merchants file most transactions for you, and Arca remembers what you teach it.

Plan ahead

Budget, bills, debts and goals

Split your income into needs, wants and savings, see every bill before it lands, and watch debts shrink and goals fill up.

Look ahead

A forecast that warns you

See where your balance goes over the next 30 days or 3 months, and get a heads-up before you run short.

Yours

On your own server

One small database in one folder. No cloud account, no tracking. Several people in a household, two-factor sign-in and an app lock.

Everywhere

Desktop and phone

Light and dark, English and Dutch. Add it to your phone’s home screen and it opens like an app.
