>_ Products
Production-ready code, delivered instantly.
>_ REST API Starter
A complete Python REST API server built on stdlib http.server. Includes declarative routing, middleware pipeline, structured error handling, request validation, CORS support, and auto-generated OpenAPI 3.0 documentation. Zero dependencies — just unzip and run.
>_ GraphQL Boilerplate
A lightweight Python GraphQL server built entirely on the standard library. Supports schema definition, field resolvers, query parsing, type validation, introspection queries, and error formatting. Includes a built-in GraphiQL-style query explorer served as static HTML.
>_ Webhook Handler
Production-ready webhook receiver that handles signature verification (HMAC-SHA256), automatic retry with exponential backoff, dead letter queuing, event routing to handler functions, and structured logging. Supports multiple webhook providers (Stripe, GitHub, generic HMAC) out of the box.
>_ Rate Limiter
Four production-ready rate limiting algorithms in a single Python module: Token Bucket, Sliding Window Log, Sliding Window Counter, and Fixed Window. Supports IP-based, API-key-based, and custom key extraction. Includes HTTP middleware integration and rate limit headers (X-RateLimit-*).
>_ API Key Manager
Complete API key lifecycle management: generation with configurable prefixes, HMAC-based validation, automatic expiration, scope-based permissions, key rotation with grace periods, and usage tracking. Keys are stored in a JSON file database with O(1) lookup via hash indexing.
>_ OpenAPI Spec Generator
Automatically generates OpenAPI 3.0 specifications by introspecting Python functions. Extracts path parameters, query parameters, request/response bodies, and descriptions from type hints and docstrings. Outputs valid YAML or JSON specs that can be imported into Swagger UI, Redoc, or Postman.
>_ Mock Server Builder
Reads an OpenAPI 3.0 spec (JSON or YAML) and spins up a fully functional mock HTTP server. Returns example responses defined in the spec, generates fake data for schemas without examples, supports path parameters, and validates incoming requests against the spec.
>_ API Test Framework
A lightweight API testing framework with a fluent request builder, chainable assertions, test suite runner, performance benchmarking, and HTML report generation. Write expressive API tests without any third-party dependencies.
>_ API Versioning Toolkit
Implements three API versioning strategies in a single toolkit: URL path (/v1/users), custom header (X-API-Version), and query parameter (?version=1). Includes version negotiation, deprecation warnings, and migration helpers for transitioning between versions.
>_ API Docs Generator
Transforms OpenAPI 3.0 specs into beautiful, self-contained static HTML documentation. Features a dark theme with syntax highlighting, interactive endpoint explorer, request/response examples, and a search function. Output is a single HTML file you can host anywhere.
