Sideko is an API tooling generation platform that turns an OpenAPI specification into a complete developer-tooling suite — SDKs in six languages (Python, TypeScript, Java, Go, C#, Rust), Model Context Protocol (MCP) servers for AI agents, on-brand documentation sites with an Automatic MCP surface, mock servers, and CLI tooling — without writing generation code. The platform's "Hybrid Codegen" pairs deterministic OpenAPI-driven generation with guided AI customization, and ships LLM coding-assistant rule files (Claude Code, Cursor, Gemini, GitHub Copilot) alongside each SDK so agents can extend the generated code without breaking regeneration. Customers include Prudential Financial and Magic Hour AI; Sideko's published Stripe SDK benchmark generated over one million lines of SDK code in under sixty seconds.

The Sideko REST API enables developers to programmatically manage API projects, generate SDKs in six languages (Python, TypeScript, Java, Go, C#, Rust), generate Model Context Protocol (MCP) servers from OpenAPI, lint specifications for generation-readiness, deploy mock servers, and publish on-brand API documentation sites.

The Sideko CLI is a Rust binary (current release v1.6.3, Aug 2025) with five resource groups — sideko api, sideko sdk, sideko doc, sideko account, sideko config — including SDK generation for Python, TypeScript, Java, Go, C#, and Rust with optional GitHub Actions and LLM coding-assistant rules (Claude Code, Cursor, Gemini, GitHub Copilot). Installs via Homebrew, pip, npm, or curl.
