Salut / Hello everyone,

I’m currently building a small financial tracking app for rental owners and I’m hitting a wall regarding banking integration in Switzerland.

In the EU, there are a lot of cheap and easy solutions which made things somewhat affordable, but here it feels like the "Wild West" (or rather, the "Expensive East").

I've looked into SIX bLink, seems to be the gold standard, but the entry barrier for a small bootstrap project is huge (onboarding costs + monthly minimums).

My question: Has anyone found a workaround or a "lightweight" provider that doesn't cost a lot, just to get read-only access to transaction history for the main Swiss banks (UBS, Raiffeisen, ZKB, PostFinance)?

Is there a Swiss-specific aggregator I’m missing, or maybe a way to leverage the "Common API" initiative without breaking the bank?

I’m currently stuck with CSV imports (which works but the UX is... 2010), and I'd love to offer a more "2026" experience.

Thanks for any tips or leads!
