This articles explains our SDK generation solution that utilizes a macro! in the Rust programming language to maintain custom files added between code generations with zero configuration.

Sideko's new C# SDK generator, leveraging C#'s growth (+1.43% in TIOBE), creates invisible, fully tested, strongly typed, and auto-authenticated SDKs with customizable code and complete documentation.

Sideko's Rust-based SDK generator created massive Python (~607k lines) and TypeScript (~421k lines) Stripe SDKs in under 60 seconds on a 1GB container, saving an estimated 9 engineer-years of development time.

Rushing to deploy MCP servers despite poor OpenAPI specs is causing developer disappointment. Inaccurate specs, even from top companies like GitHub, lead to broken implementations. Mastering accurate OpenAPI is crucial for long-term API success and agent-API interaction, avoiding future rebuilds.

Sideko launched its API Ecosystem Platform, transforming APIs into complete products (docs, SDKs, CLIs) for modern integration experiences. Used by Prudential and 200+ businesses, it's SOC-2 Type II compliant and built with Rust for performance.
