Firefly III is a great ledger. Budgero Self-Host is a budgeting app: zero-based envelopes, 168 currencies with live FX, end-to-end encryption, and an offline-first PWA — free on your own server.
Or try Budgero Cloud free for 35 days — no card, no server needed.
Let's be fair to Firefly III first: it is free, open source, actively maintained, and one of the most complete double-entry personal finance systems you can run yourself. If you think in accounts, journals, and reports, it is excellent — and if open-source licensing is non-negotiable for you, Firefly III or Actual Budget is the right call, not Budgero.
The reason people go looking for an alternative is usually not a missing feature — it's a mismatch of method. Firefly III records what happened. Zero-based envelope budgeting decides what happens next: every unit of money gets a job before you spend it. Firefly has budget features, but they sit on top of an accounting core; in Budgero, the envelope method is the core, the same philosophy that made YNAB work — with 168 currencies handled natively.
The second reason is the household test: Firefly III makes sense to the person who set it up. A spouse logging groceries on a phone at the supermarket needs something else — Budgero's PWA installs like a native app, works offline, and syncs when you're back online.

Key takeaway: pick Firefly III for an open-source double-entry ledger with deep reporting. Pick Budgero for zero-based envelope budgeting your whole household can use, real multi-currency, and end-to-end encryption — still free, still on your server.
The two most common reasons: budgeting method and day-to-day ergonomics. Firefly III is a double-entry personal finance ledger — superb for recording and reporting on what happened, less natural for forward-looking envelope budgeting. And while Firefly's web UI is powerful, there's no official mobile app and the learning curve is real. If you want YNAB-style zero-based budgeting on your own server with a polished, offline-capable PWA, that's exactly the gap Budgero Self-Host fills.
No. Budgero is proprietary software that you can self-host for free with the full feature set. If open-source licensing is a hard requirement, Firefly III and Actual Budget are the right choices — and we genuinely recommend them for that case. If what you actually want is "my data on my server, no subscription", Budgero Self-Host delivers that without the license.
Firefly III supports multiple currencies at the transaction and account level, but budgeting and reporting across currencies is limited — it remains primarily a one-main-currency system. Budgero treats multi-currency as the core feature: 168 currencies in one budget, live exchange rates, and a unified home-currency rollup across all accounts and envelopes.
Yes, via CSV. Export your transactions from Firefly III (it has solid export options), then import the CSV into Budgero — accounts, dates, payees, amounts, and categories map in a preview before anything is written. Plan an evening for it if you have years of history and want to tidy categories afterwards.
Docker and roughly 10 minutes: pull the image, copy the example docker-compose.yml, set a few environment variables, and docker compose up. It runs comfortably on a Raspberry Pi, a NAS, or the smallest VPS tier. There is no license key, no telemetry unless you opt in, and no feature gating versus the Cloud edition.
Real Users, Real Budgets
People who switched from YNAB and other tools share their experience.
I used YNAB for years and love zero-based budgeting. Budgero nails the same methodology with a design I actually enjoy using. I keep coming back because I'm a budget geek. The SQL Explorer is a dream if you have a technical background.
I started with YNAB and then tried a bunch of different tools over the past year. Budgero is the closest to perfect for my use case while also matching what I want visually. Transaction entry is fast, the savings goals with sub-sections are exactly what I need, and the whole experience just feels right.
The app is really advanced in both functionality and UI. I was impressed by how polished the whole experience feels. This is a serious budgeting tool with a design that competes with anything on the market.
The latest update made a noticeable difference. Animations are smoother, everything feels faster. Nice to see a budgeting tool where the developer actually cares about performance.
Spin up Budgero Self-Host with Docker in about 10 minutes — free forever, full feature set, no telemetry unless you opt in.
