Nobody complains that Hey API is too slow. To keep it that way, we're about to make it faster.

"@neon/sdk is fetch-based, zero dependencies and ESM-only. The raw client is generated from our OpenAPI spec with Hey API, so every endpoint maps one-to-one to a TypeScript function." Thank you for betting on Hey API, @neon.com!

Welcome @skk.moe to the Hall of Fame! He's the mastermind behind the major performance improvements to our generators, including making them up to 40× faster for large specifications. Thanks for making Hey API faster for everyone! 🚀🚀🚀

We just donated to @heyapi.dev as part of our open source donation program! It's a TypeScript toolkit that turns your OpenAPI spec into a fully typed API for frontend and backend. We use it so much that one of our engineers, Yuri Mikhin, even built the NestJS plugin for it.

Turns out no feature is a small thing. Reverted in the latest release, back to the drawing board.

Authoring plugin configuration has always been verbose and painful, especially for deeply nested or complex options. The next release aims to solve this with a new, declarative approach. If you're writing custom plugins on top of Hey API, we'd love your feedback!

Anthropic is not acquiring @heyapi.dev, an SDK generator that has powered no @anthropic.com SDK since the earliest days of their API.

Congratulations to Alex Rattray and Stainless on getting acquired by @anthropic.com! Hey API quite literally wouldn’t exist without you and your support over the years.

I have tried many OpenAPI -> SDK solutions, and Hey API has the best DX among them: the best client request options shape, the easiest setup, and it just works out of the box.

🚨 BREAKING: Developers are projected to download packages from Hey API, used by @vercel.com and OpenCode, at least 3 million times per week, per npm.

Hey API featured in @apisyouwonthate.com: “We are currently living in an era where people want us to stop caring about quality. It's really great to see the focus on quality and end-user experience in the OpenAPI space.” Thank you @alexanderkaran.bsky.social!

Hey API is an incredible tool — an absolute must-have for our team 🙌 I am so glad that I could contribute back and improve it a bit! Tracing those bottlenecks was a fun challenge, and knowing a up to 30x speedup benefits teams of all sizes makes it totally worth it! 🚀

Hey API @heyapi.dev · 28/04/2026

v0.97.0 is out with a huge contribution from @skk.moe! They noticed generation was painfully slow on large OpenAPI specs, traced it to several algorithmic bottlenecks, and fixed them. The result is a 10x-30x performance gain on larger specs, with meaningful improvements on smaller specs as well.

The best* marketing is when your users do the talking. See Devlin Duldulao at React Miami (April 23–24) as he demos how Hey API helped him ship a large-scale React app while writing less than 1% of the codebase.
