DumbBudget

"Stupid simple software" is the entire philosophy at DumbWare.io, and DumbBudget delivers it: no over-engineering, no complexity, no accounts, no bank connections - just a clean, modern ledger for money in and money out. Log income and expenses, assign categories, and watch real-time balance calculations update as you type. Finding transactions is quick: filter by type, narrow by date range, sort by date or amount. When tax season or spreadsheet analysis calls, everything exports to CSV. Access control matches the philosophy - a single PIN (set via one environment variable) gates the app, backed by real security engineering: rate limiting on PIN attempts, temporary lockout after failures, secure session handling, and no sensitive data in browser storage. Multi-currency support covers the ISO codes, and a SITE_TITLE variable names each instance - deliberately useful, because running separate instances per account or family member is the intended pattern for multi-user needs. The responsive UI ships light and dark themes and installs as a PWA on phones, where expense logging actually happens. Configuration is five environment variables; data persists in one folder. If Actual Budget and Firefly III feel like accounting software, this is the notepad that gets used. GPL-licensed.
