BugCanary

The offensive-security practice we run ourselves: manual penetration testing, bug bounty work, pre-launch reviews. It is why security is part of every PeakStack build from the first commit.

Accessibility remediation for EU online shops.

The European Accessibility Act has applied since June 2025. We scan your storefront, name each defect we find with the WCAG criterion it fails, and fix them in a fixed-price sprint. Then we re-scan on a schedule and report anything that regresses.

  • The scan comes first, and the quote comes from the scan
  • Evidence for every fix, before and after
  • You publish your own accessibility statement. We supply the fixes and the evidence, not a compliance certificate.
  • Web and mobile products.

    Next.js on the web, React Native for iOS and Android from one codebase.

  • AI inside the product.

    Assistants that book, answer and extract, grounded in your own data, with a person in the loop where a mistake is expensive.

  • Retail, POS and payments.

    Catalog, ordering, loyalty and checkout, built for a real shop floor.

  • Security from the first commit.

    Threat-modelled before it is built, attacked before it launches, by the people behind BugCanary.

  • Some of this work was built under agreements that keep it private, so it is not shown above. Ask about it on the call.

Every engagement starts with a fixed first deliverable.

These are starting ranges, not a quote. The real number is written down before the build starts.

Accessibility sprints are not priced here. They are quoted from a scan of your shop.

Tell us what you're building. We'll tell you what it takes.

Three short steps, then a 20-minute call, or a written answer if you would rather skip the call.

What do you need?

Questions

Who owns the code?

You do. Ownership of the software passes to you on delivery and payment. The repository, cloud accounts, domain and store listings are opened in your name, so when an engagement ends you remove our access and nothing else has to move.

What if you disappear?

Nothing we build lives anywhere you cannot reach: your repo, your accounts, your billing. Every project ships with setup and deploy documentation, on mainstream frameworks any competent team can pick up.

How long does it take?

A custom private build takes 1–4 weeks. A product build typically takes 4–12 weeks.

How do you handle security?

Threat-modelled before it is built, attacked before it launches, by the people behind BugCanary.

Do you certify accessibility compliance?

No. We fix the defects and hand you the evidence, before and after. You publish your own accessibility statement.
