Building a High-Performance OpenAPI Parser in Go

One observation I've had recently. Postman files seem more popular the OpenAPI specs lately. Major SaaS companies will produce a postman file but not an OpenAPI spec. Two examples: Salesforce and Notion

This is really unfortunate because Postman requires you to have an account and log in to download or export these to another format.

Prediction: Postman produces a paid MCP for API lookup in the near future

Postman is my goto example for saas enshitification.

Something that should have just stayed foss.

> we process thousands of OpenAPI specifications every day

Doesn't really strike me as the load that requires writing a high-performance solution from scratch, especially on modern hardware.

> Some were fast but modeled the spec loosely, making it hard to build correct tooling on top. Others were closer to the spec but used untyped maps everywhere, which made large refactors and static analysis painful.

Correctness and types were the real reasons?
