We build the runtime layer for pricing usage-based and AI-embedded software.
Formata is the company behind Limitr and Stof. Both come out of the same idea: pricing and configuration shouldn't be scattered across a codebase — they should live in one document that carries its own logic and enforces itself, wherever your app runs.
The pricing runtime for usage-based software. Define plans, entitlements, credits, and spend caps as a single policy document, and enforce them in-process — no network call on the hot path, no redeploy to change pricing.
The open-source data runtime underneath Limitr. Data that carries its own logic — a superset of JSON that runs anywhere, sandboxed, via WebAssembly.
