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! 🚀🚀🚀
. @skk.moe has been absolutely on fire with optimizing our generator performance and deserves way more but it's a start
sukka@skk.moe · 2mo agoThanks @heyapi.dev (HeyAPI.dev) for their generous sponsorship via GitHub Sponsors 🙏 Have been enjoying digging into the internals — made it 30x faster, then squeezed out another 15%, now another 15% performance gain is right on the horizon. Onward with Hey API🚀
“That’s 5,000 small stars for a man, one giant milestone for Hey API.” Thank you to more than 5,000 of you who showed your support by leaving a star on our GitHub repository 🤩

Still using Python 3.9? Hey API will let you choose your minimum supported Python version, so generated code can take advantage of newer language features.
These are your @pydantic.dev models generated by datamodel-code-generator, a popular Python utility. And these are your models generated by Hey API, coming soon. Join the waitlist on our website today.
Delighted to welcome Unblocked as our newest sponsor. Thank you for sponsoring free and open source software!
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.
Evil Martians@evilmartians.com · 4mo agoWe donated to @pnpm.io as part of our open source donations program. It's the default package manager for many of our frontend engineers. The team behind the 11.0 release did an amazing job of securing pnpm against supply-chain attacks, making it one of the safest package managers out there.
Thank you @evilmartians.com for sponsoring Hey API. People like you make projects like this possible!
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!
Which OpenAPI codegen should you choose? "Hey API felt like the best balance." – @nyaomaru-dev.bsky.social Link in the comments.
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.
Every docs page now shows the funding status. As alarming as it is, Hey API is easily one of the more sustainable projects.
It’s about 12,000,000 times every month now. And still so early.
Hey API@heyapi.dev · last yr.Hey API is now being downloaded over 2,000,000 times every month! 🤯 Thank you for using Hey API to generate your SDKs, and for all your feedback and support. Instead of release notes, enjoy a release song. 🎶
Excited to welcome Photon to our growing fleet of sponsors! Thank you for supporting free and open source software!
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.
Hey API@heyapi.dev · 4mo ago🚨 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.
