The short answer
The two leading self-hosted finance apps in 2026 are Firefly III (24,208 stars, AGPL) - a complete double-entry bookkeeping system for personal finance - and Actual Budget (27,894 stars, MIT) - a modern, fast budgeting app with a great UI. Both can be paired with LLMs for automatic transaction categorization.
Firefly III - the complete ledger
- Double-entry accounting principles, multi-currency, recurring transactions.
- Budgets, bills, piggy banks, and detailed reporting.
- Data import from banks via CSV or APIs (many bank exporters exist).
- Web UI + REST API; runs via Docker easily.
- AI angle: its API lets you send transactions to an LLM for category suggestions.
Actual Budget - the modern minimalist
- Fast, local-first budgeting with a clean UI (think YNAB, but self-hosted).
- Envelope-style budgeting with rules for auto-categorization.
- Multi-device sync built in (via a server component).
- Open source (MIT) - fork-friendly.
The 2026 AI workflow
- Export bank transactions as CSV.
- Let the app's rules handle obvious categories (groceries, rent).
- For the rest, batch-send to an LLM: "Categorize these transactions into my budget categories, return JSON" - then review and import.
- Monthly: ask an LLM to summarize spending trends from the app's reports.
The LLM step is a prompt, not a plugin - you pipe data through any model you trust. Never give an LLM your full financial history unless you use a local model.
FAQ
Is self-hosting finance data safer? It stays on your server, but you own the security burden - keep backups and use HTTPS if exposed.
Which is easier for beginners? Actual Budget has the gentler learning curve; Firefly III is more powerful but more complex.
Do they support bank sync automatically? Both rely on manual CSV import or community connectors; automatic bank feeds depend on your bank's support.
