On August 31, 2026, ibanchecker.cash launches on Product Hunt. I'm Koray, the founder. I designed, built, and still ship most of this project myself, with a small team helping on support, marketing, and QA. This post is the short version: why I built a free IBAN checker, what has actually shipped, and how you can help on launch day.

Why Am I Putting ibanchecker.cash on Product Hunt?

ibanchecker.cash is bootstrapped, no investors, no growth targets to hit. I built it because most IBAN validators either fail silently when a check fails or lock every useful feature (bank lookup, bulk checking, an API) behind a paywall with no meaningful free tier. Product Hunt's community is exactly the audience I want scrutiny from: people who build payment flows, fintech products, and developer tools, and who will tell me directly when something is wrong instead of quietly bouncing. I am not chasing a launch day spike; I want the bug reports and the honest “this is missing” comments more than the upvotes.

What Does ibanchecker.cash Actually Check?

A privacy-first IBAN toolkit covering 92 countries. The free tools:

  • IBAN Checker: structural validation (ISO 13616, MOD-97), plus national account check digits for 25 countries, the UK modulus check, and the German Prüfziffer, the two account-level checks that most validators, including paid ones, skip entirely.
  • Bulk Checker and Smart Extract: validate up to 10,000 IBANs at once, or pull every IBAN out of a pasted document.
  • Payment QR generator and decoder: build or read back a SEPA EPC payment QR code field by field, so you can see exactly what a code will pre-fill before you scan it.
  • RF Creditor Reference generator and half a dozen bank-code converters (sort code, BLZ, RIB, and more).
  • A Developer API with a real free tier, official Python and PHP clients, and an MCP server so AI assistants can call it directly.

No IBAN is ever logged or stored, in the UI or the API. That is not a slogan; the exact architecture is written out on Data Methodology and Security & Trust.

What's Shipped Recently, Ahead of the Launch?

I keep a public changelog, so none of this is a launch-day surprise. Some of what landed in the run-up:

  • Official API clients for Python (pip install ibanchecker) and PHP (composer require ibanchecker/client)
  • A rebuilt payment QR generator (SVG, PDF, live preview) and a new QR decoder that reads a code back and validates the account it names
  • A bank-code identifier: paste any code and find out whether it's an IBAN, a BIC, or something else
  • An ISO 11649 RF creditor reference generator and validator
  • Verification of Payee scheme participation shown directly on validator results
  • “Who owns this bank” parent-group context on bank and BIC pages
  • Support for Burundi and Mongolia, bringing total coverage to 92 countries

How Can You Support the Launch on August 31?

The listing is already up for following. Upvoting turns on automatically once the launch goes live at 12:01 AM PDT on August 31. If you have a moment that day:

  • Visit the Free IBAN Checker page and upvote if you find the tool useful.
  • Leave a comment, ideally an honest one. A “this part confused me” is worth more to me than a generic “congrats.”
  • If you run into an actual bug, tell me directly through Contact. I read and act on every one of these myself.

This is a bootstrapped, ad-free project. Product Hunt feedback directly shapes what I build next, more than any roadmap I could write on my own.
