All the Features of a Personal Finance App, Hosted by You
With everything from AI-powered insights to multi-currency tracking and CSV import — Cashlytics has everything a modern personal finance app needs, without the monthly bill.
Personal Finance Dashboard
View your entire financial picture at a glance. KPI cards display balances, spending, and net worth across all your accounts.
Budget Analytics & Spending Forecasts
See where your money comes and goes each month, and look into the future with smart trend analysis. Identify problem categories before they become problems.
AI Financial Assistant
Ask your finances a question — in plain language. Cashlytics' built-in AI assistant reads your transaction history and gives you straight answers about your spending, savings, and financial habits. No other free self-hosted finance app includes this.
Multi-Account Tracking
Access checking, savings, credit cards, and investment accounts all in one place. Every account. One dashboard.
Custom Categories & Tags
Add categories that reflect your real life — with custom icons, colors, and groupings. Your budget, your rules.
Dark & Light Mode
Switch between a polished dark theme and a clean light mode. Finance tracking shouldn't hurt your eyes.
Multi-Language Support (EN/DE)
Use Cashlytics in English or German out of the box. Additional languages can be added — Cashlytics is built for global self-hosters.
Multi-Currency Support
Track accounts in different currencies. Automatic conversion keeps your totals accurate whether you earn in EUR, USD, or anything else.
Receipt & Document Upload
Attach receipts and invoices directly to transactions. Complete financial records, no paper required.
CSV Import Workflow
Import transactions from any bank via CSV. Cashlytics first stages each row, marks duplicates, and lets you verify before committing — no surprise imports.
Secure User Authentication
Password-protected login with full password reset support via SMTP. Secure by default, configurable for your setup.
Multi-User Household Support
Invite family members or a partner. Each user gets their own private data space — separate accounts, shared server.
Single-User Privacy Mode
Just need it for yourself? Single-user mode removes the login screen entirely. Pure, frictionless personal finance.
SMTP Email Integration
Connect your mail server for verification emails, password resets, and payment reminders. Works with Gmail, Mailgun, or any SMTP provider.
Installable PWA
Install Cashlytics on your phone or desktop like a native app. Works on iOS, Android, and desktop browsers — no app store required.
