Ironfang · Software products, UK-built
Ironfang builds and runs small, sharp developer tools on our own UK infrastructure - starting with Renderwolf, a rendering API for screenshots, PDFs and social images.
Products
Self-service tools we design, host and support ourselves, end to end - from the silicon to the API contract.
One rendering API for screenshots, PDFs and templated social images - served by a warm Chromium fleet, so there are no cold starts and no surprise bills.
More small, sharp tools are taking shape behind Renderwolf - including APIs for UK company data. One thing at a time, built properly.
Tell us what you'd useHow we build
Fifteen years of building platforms for other people, distilled into six principles our own products ship by.
Everything runs on Ironfang's own EPYC and NVMe infrastructure in the UK - engineered by us, not resold cloud.
Warm pools and edge caching, engineered so p95 latency is a feature, not a footnote.
Isolated workloads, least-privilege networks and encryption everywhere, designed in from day one.
Clean, versioned JSON APIs with honest docs, stable error codes and predictable rate limits.
Sign up, get a key, build. No sales calls, no demos, no "contact us for pricing".
Hard caps instead of surprise bills. And when something breaks, the status page says so.
The toolkit
Battle-tested languages and platforms, from the API layer down to the hypervisor - picked to keep our products fast, secure and dependable for years.
