Official SDKs

One distribution with the shared sync/async client and optional framework adapters. Drop-in middleware for every major Python web stack, plus direct clients for scripts, workers, and custom frameworks.

One npm package with the shared async client and framework adapters — ESM and CommonJS, with complete TypeScript declarations. Drop-in middleware for Express, NestJS, Fastify, Koa, Next.js, and plain Node, plus the direct client for scripts and workers.

One module with a concurrency-safe client, standard net/http middleware that also fits Chi and Gorilla/Mux, and native adapters for Gin, Echo, and Fiber — typed decisions, typed errors, and idiomatic pointer options throughout.

One crate with a shared async core, a blocking client for synchronous apps, and optional native adapters for Axum, Actix Web, Rocket, and Warp — typed decisions, typed errors, and synchronous resolvers throughout. Framework features are opt-in, so the core never pulls a web framework into your build.

One Composer package with a framework-neutral client and middleware engine, plus adapters for Laravel, Symfony, and any PSR-15 dispatcher (including Slim 4) — configured in a file or by named-argument constructor, with typed enums and typed exceptions throughout. PHP 8.1+.

Two NuGet packages for C# on ASP.NET Core — a framework-neutral client and the ASP.NET integration with DI registration, middleware, Minimal API conventions, and MVC attributes. Configure in code or bind from appsettings.json, with typed enums and typed exceptions throughout. .NET 8.

Four Maven Central artifacts for the JVM — a framework-neutral core with the JDK HTTP client and shared middleware engine, plus thin adapters for Spring Boot, Jakarta Servlet, and JAX-RS. Configure in application.yml or with a fluent builder; Quarkus and Micronaut reuse the JAX-RS or Servlet adapters. Java 17+.
