Why Ironfang

Built for dependable operation

More than fifteen years of production engineering, applied to products we design, build and operate ourselves.

  • UK-operated infrastructure

    Renderwolf runs on infrastructure Ironfang operates in the UK, providing direct control over performance, capacity and data location. Customer workloads are isolated by design.

  • Built for integration

    Versioned JSON APIs, stable error codes, predictable limits and practical documentation support implementation and ongoing operation.

  • Self-service from day one

    Create an account, generate a scoped API key, monitor usage and manage your subscription from the dashboard.

  • Predictable usage and billing

    Warm infrastructure, caching and hard usage caps support consistent performance while preventing automatic overage charges.
