Best open source alternatives to YNAB and PocketSmith for Australians (2026)

Most of the well-known budgeting apps are subscriptions you rent forever. YNAB is around US$109/year, PocketSmith's paid tiers run roughly US$10–20/month, and the late Mint pushed everyone toward Credit Karma when it shut down. You pay every year, your data lives on someone else's servers, and if the company pivots or folds you're left exporting CSVs in a hurry.

Open-source personal finance tools are the other end of the spectrum. The code is public, you can self-host so your financial data never leaves a machine you control, and there's no annual licence quietly renewing on your card. The trade-off is that you're more on your own for setup, and if you're in Australia, most of them have no idea how to talk to your bank.

This is a rundown of the open-source options actually worth your time in 2026, split into the ones Redbark connects to directly and the ones it doesn't (yet). If you just want the short version: Actual Budget and Sure are the two we'd point most people at, and they're also the two we can pipe Australian bank transactions straight into.

A note on the Australian bank-feed problem

Before the list, the thing nobody tells you up front: almost none of these tools can pull transactions from an Australian bank on their own.

Open-source budgeting apps are mostly built by people in the US and Europe, so their built-in bank syncing leans on aggregators like SimpleFIN (US/Canada) and GoCardless or Nordigen (UK/EU). None of those cover Australian institutions properly. YNAB and PocketSmith have the same gap from the other direction: YNAB only does direct feeds for US, Canadian, UK and EU banks, so Australians are stuck doing manual file imports there too.

That's the hole Redbark fills. We pull your transactions through Fiskil, an ACCC-accredited Open Banking (Consumer Data Right) data recipient, and push them into the destination of your choice. You authenticate at your own bank, your password never touches us, and consent is visible and revocable from your bank's app. There's more on exactly how that works in How Redbark handles your data.

So as you read the list, keep two questions separate: is this a good app? and can I actually feed it my CommBank transactions without typing them in by hand? For the first two tools, the answer to both is yes.

Open-source tools Redbark connects to

Actual Budget

Actual Budget is the one we recommend to most people coming from YNAB. It's a local-first, MIT-licensed app built around the same zero-based, envelope budgeting method YNAB popularised: every dollar you have gets a job before you spend it, and you can only budget money you actually hold.

What makes it stand out is that it's local-first: your budget lives on your device and works offline, and a sync server (which you self-host, or pay them ~US$8/month to host) keeps multiple devices in step without your data sitting in someone's analytics pipeline. That sync server has optional end-to-end encryption, so even the synced copy is unreadable without your key. It's fast and genuinely pleasant to use, closer to a polished commercial app than most open-source finance software, which tends to look like it escaped from 2008. And it's free to self-host forever; a single Docker container is all it takes.

Actual ships with bank syncing via SimpleFIN and GoCardless, neither of which works for Australian banks. That's where Redbark comes in: we run as a Docker container alongside your Actual server, dedupe transactions by imported ID so you never get duplicates, and support end-to-end encrypted budgets. There's a dry-run mode so you can preview an import before it touches your data. Full details on the Actual Budget destination page.

Best for: YNAB refugees who want the same envelope method, own their data, and stop paying a yearly subscription.

Sure

Sure is the community-run continuation of Maybe Finance. Maybe was a slick, well-funded personal finance app (net worth tracking, accounts, investments, the lot) that open-sourced its code and then wound down the hosted product in mid-2025. Because the code was public (AGPLv3), the community forked it and kept going under the name Sure.

Where Actual is laser-focused on budgeting, Sure is more of a full personal finance dashboard: net worth over time, account balances, investments and spending all in one place. It's the better pick if you care less about strict envelope budgeting and more about seeing your whole financial picture.

It's self-hosted via Docker like the others. Redbark syncs into Sure as a stateless container (nothing stored locally) with dual-layer deduplication (exact match plus a fingerprint), optional category mapping, and the same dry-run preview. See the Sure destination page for specifics.

Best for: people who want a net-worth-and-everything dashboard rather than a pure budgeting tool, and don't mind that it's younger and community-maintained.

A quick word on Maybe itself: you'll still find the original maybe-finance/maybe repo on GitHub, but it's archived and unmaintained. If someone points you at "Maybe", what they almost certainly want now is Sure.

Strong open-source tools Redbark doesn't connect to (yet)

These are good tools; they just aren't Redbark destinations today. We list them honestly because the right answer for you might be one of them. If you land on one of these and still want automated Australian bank data, you can usually bridge it yourself: Redbark offers a generic Webhook destination and a REST API, and most of these apps have their own import API or CSV importer you can point that data at.

Firefly III

Firefly III is the heavyweight of self-hosted personal finance. It's a free, open-source manager built on proper double-entry bookkeeping, with budgets, categories, tags, rule-based auto-categorisation, recurring transactions, and "piggy banks" for savings goals. It originates in the EU and is fiercely privacy-focused, and won't contact an external server unless you tell it to.

The standout for tinkerers is its REST API, which covers almost the entire app. There's also a separate Data Importer for getting transactions in. That API is exactly the kind of thing you could wire a Redbark webhook into if you wanted Australian feeds flowing in automatically. Firefly is more app than most people need, but if you want power and control, nothing else on this list matches it.

Best for: people comfortable with double-entry accounting who want maximum control and a real API.

Ghostfolio

Ghostfolio is an open-source wealth and portfolio tracker rather than a budgeting app. It consolidates cash, stocks, ETFs and crypto across multiple brokers into one net-worth dashboard, with performance metrics over various timeframes. If your question is "how are my investments doing?" rather than "did I overspend on takeaway?", this is the open-source answer.

It's self-hostable via Docker and runs on most home-server platforms (Umbrel, Unraid, CasaOS and friends). Worth knowing Redbark can already connect a range of brokerages and crypto exchanges via SnapTrade for syncing into spreadsheets, so for the investment side there's overlap in what we cover, just not a native Ghostfolio destination.

Best for: investors who want a self-hosted alternative to Sharesight or a portfolio-tracking dashboard.

GnuCash

GnuCash is the veteran. It's a mature, desktop, double-entry accounting program that's been going for over two decades, handling personal and small-business finances with a familiar chequebook-style register. The interface looks its age (it's GTK and very 2000s) but it's rock solid, completely free, fully offline, and there's nothing it can't account for.

There are no live Australian bank feeds; you import files or enter transactions manually. It's the right tool if you want a battle-tested, no-subscription desktop ledger and don't care about a modern UI.

Best for: people who want serious, offline, double-entry accounting and trust longevity over polish.

Beancount and plain-text accounting

For the truly nerdy end of the spectrum, there's Beancount (and its cousins Ledger and hledger). These are plain-text accounting systems: you record transactions in a text file, version-control it like code, and use a tool like Fava for a web-based view of reports and charts. It's double-entry, auditable, and your entire financial history is a Git repo you fully own.

There are no bank feeds, no GUI for data entry, and a real learning curve. But for engineers who want their finances to be diffable, scriptable and outlive any company, nothing beats it.

Best for: developers who'd rather edit a text file than click around an app.

Quick comparison

How open source stacks up against YNAB and PocketSmith

The honest comparison: YNAB and PocketSmith are more polished, more hand-holding, and work out of the box. You don't run a server, you don't read docs, you just sign up. For a lot of people that's worth the subscription.

What open source gives you instead is ownership and permanence. Your data sits on hardware you control, the app can't be discontinued out from under you (Mint and the original Maybe are the cautionary tales), and once it's set up there's no annual bill. Actual Budget in particular has closed most of the polish gap; for envelope budgeting it genuinely competes with YNAB on feel, not just on price.

The one thing the commercial apps could always claim over the open-source crowd in Australia was bank feeds. PocketSmith pulls from thousands of institutions; YNAB at least does direct feeds overseas. That advantage is what Redbark neutralises for Actual and Sure: you get the open-source app and automatic Australian transactions, instead of having to choose.

Getting started

If this nudged you toward Actual Budget or Sure, the setup is roughly:

1. Self-host the app (a single Docker container for either).
2. Sign up at app.redbark.co; there's a 7-day free trial, no card required.
3. Add an Australian bank connection and grant CDR consent at your bank's own website.
4. Add Actual Budget or Sure as a destination, point it at your self-hosted instance, and map your accounts.

From there, transactions sync in the background. After the trial, Redbark plans start at A$10/month billed annually; details on the pricing page.

Prefer a spreadsheet or YNAB instead? Redbark syncs into Google Sheets and YNAB as well, and there's a step-by-step YNAB guide if that's where you're headed.

Whatever you pick, the point stands: you no longer have to choose between owning your financial data and not typing every transaction in by hand. Questions? Reach us at support@redbark.co.
