I got tired of importing CSVs from my bank every week, so I built a self-hosted sync layer for EU banks → Notion, Sheets, Airtable

I spent way too long trying to get bank data into Notion automatically. Here's what I actually ran into — and what I ended up building.

The no-code finance stack is almost there.

Notion, Sheets, Airtable they're all genuinely great for personal finance. You can build dashboards, category breakdowns, monthly reports, budget trackers..

But there's one step none of them solve: getting the actual bank data in.

The CSV loop is worse than it sounds.

You log into your bank. You find the export section. You download a CSV. You open it, fix the column names, remove the garbage rows. You import it. Then you notice there are duplicates because a pending transaction already cleared — and now you have two entries for the same purchase.

You fix it manually. Next week, same thing.

This isn't a minor inconvenience. It's a recurring maintenance task that kills the habit. Most people just stop keeping the system updated.

I tried every existing option. None of them worked.

• GoCardless shut down its free tier. What's left is enterprise pricing, not something a solo person building a personal finance system can use.
• Plaid is US-focused. Useless for EU banks.
• Sync tools that exist either store your credentials on their servers, cap you at 1–2 accounts, or charge a monthly subscription per bank connection.
• Zapier/Make automations can move data around but can't connect to a bank in the first place.

The root problem: there's no self-serve, privacy-respecting, affordable bank sync layer for EU users building in no-code tools.

SyncBank is a self-hosted app that runs on your own machine. It connects to 2,600+ EU banks across 29+ countries using PSD2 Open Banking — the same standard banks use for regulated third-party access.

Here's how the auth actually works: you never type your bank password into SyncBank, it runs locally on your hardware. Your bank login is handled directly by your bank via PSD2 open banking, while SyncBank only gets read-only transaction access.

It connects to:

Notion · Google Sheets · Airtable · Actual Budget · CSV

You can also push data between destinations — for example, pull from Actual Budget and sync to Notion for reporting.

Syncs every 6 hours automatically, or you can trigger it manually from the dashboard. The dashboard shows run history, sync status per account, and any errors.

Setup uses a guided browser wizard — no technical skills required.

One-time payment, no per-bank fees, no monthly cost.

Launching tomorrow. Early price is still available until go-live — drops after launch.

Happy to answer anything about how the sync works, how field mapping is set up, or whether it'd fit your specific stack.
