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 API powers Sideko's "Hybrid Codegen" pipeline (deterministic generation plus guided AI customization) and ships LLM coding-assistant rules for Claude Code, Cursor, Gemini, and GitHub Copilot alongside each SDK.

The Sideko CLI is a Rust binary (current release v1.6.3, Aug 2025) that provides command-line access to the Sideko platform. Commands are organized into five resource groups — sideko api (create, version, lint, stats, download specs), sideko sdk (init, config, create, update, released for Python, TypeScript, Java, Go, C#, Rust, with optional GitHub Actions and LLM coding-assistant rule files for Claude Code, Cursor, Gemini, and GitHub Copilot), sideko doc (list, deploy), sideko account, and sideko config. Installs via Homebrew, pip, npm, or curl, and stores credentials in the OS-native secure store.

Sample TypeScript SDK for the Stripe REST API, Sideko-generated as the benchmark behind the "Stripe API Challenge" blog post (over 1 million lines of SDK code generated in under 60 seconds). Demonstrates Sideko's scale and is the reference used in the Code Mode MCP benchmarks against raw MCP and CLI on 12 Stripe tasks.
