API Key Management for SaaS

A middleware service that handles API key provisioning, rotation, and billing for SaaS apps that need to manage user API keys (BYOK) or issue keys to customers. Solves the complexity of securely managing thousands of API keys across users without building this infrastructure from scratch.

With AI-native products and LLM wrappers exploding, more developers are shipping API-first tools that need to issue keys to customers or support BYOK patterns — infrastructure that was rarely needed at the indie scale a few years ago but is now table stakes even for small products. Workos and Unkey are the closest incumbents here, with Unkey specifically targeting this exact space and already gaining traction in the developer community, which is the sharpest risk to differentiation. The $2k–10k/mo revenue band is plausible since this is metered, usage-adjacent infrastructure that can justify per-seat or per-key pricing, but the ceiling is low unless the product expands into adjacent auth or billing territory. The most likely failure mode is that Unkey or a similar open-source solution captures enough mindshare that paying for a hosted competitor becomes a hard sell, especially to developers who reflexively self-host security-adjacent tooling.
