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 for all my future React TanStack Query projects.

A picture is worth a thousand words. The latest release brings unrivaled performance on large OpenAPI specifications. Install 👉 `npm i @hey-api/openapi-ts`

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! 🚀

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.

"Every year I revisit the same question: What's the best way to generate typesafe, ergonomic frontend code from my API definitions?" Sascha Becker wrote an in-depth review featuring Hey API and our friends at @the-guild.dev. Link in the comments!

“Hey API didn’t have NestJS support—so we built it.” Yuri Mikhin from @evilmartians.com published a new article showcasing a contract-first approach with NestJS. Link in the comments!

If you’re using the new npm website, please leave openapi-ts a like! npmx.dev/package/@hey...

Yuri Mikhin from @evilmartians.com is back with another article, this time showcasing contract-first development with OpenAPI, Fastify, and Hey API. Link in the comments!

Yuri Mikhin from Evil Martians wrote a new guide on setting up a TypeScript application from scratch using React, Zod, MSW, and (shockingly our favorite) Hey API. Give it a read in the comments!

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.

Hey API ❤️ @mintlify.bsky.social Thank you Mintlify for supporting free and open source software. This little astronaut will get back to work… right after he finishes his lunch.

Excited to announce that Hey API has been acquired… …over 1,000,000 times last week via npm. Thanks for acquiring it!

2026 Community Update!

Announcing the road to oRPC v2! 🎉 We need your input, ideas, and feature requests to make the next major release amazing. This is your chance to shape the future of oRPC. Discuss here: github.com/unnoq/orpc/d...

Hey API ❤️ Opencode Dance for me boy!!

Our sponsor family is growing! 👫 Thank you to OpenCode for supporting Hey API! One day, this astronaut won’t have to dance anymore.

React folks, quiet launch alert 🚀 I just shipped Formisch for React — the form library I originally built for @solidjs.com that people kept begging me to port.

Hey API has reached 3,000,000 monthly downloads! 🎉 Thank you for your support and for making Hey API part of your infrastructure.

Thank you to Luke and the team at Architect for sponsoring Hey API. The little astronaut will make it to morning!

“OpenAPI codegen that just works.” — @rauchg.blue Thank you @rauchg.blue for recognizing @heyapi.dev as a foundational open source project through your personal grant.

Hey API isn't just for tech companies. This little astronaut helps governments worldwide build better digital services for their citizens.

Thank you to our friends at @openstatus.dev and @vercel.com for sponsoring Hey API! 🤝 "A dollar a day keeps the VCs away," they say.

After 617 days, the little astronaut detached from the parent craft and will continue to explore uncharted territory.

Looking for my next role! I thrive where I can help others grow, and where my Vue.js open-source work is supported with time Frontend, AI, remote-friendly, and open to (some) relocations!

It’s time for Pinia Colada 🍹 The latest release v0.82.0 comes with a brand-new plugin for Pinia Colada by @esm.dev. Cheers!

Hey API and chill? 🎥 What do Netflix and Hey API have in common? They both provide great streams! Server-sent events (SSE) are live in v0.81.0. Happy streaming!

Using an API registry? 📦 Now you can quickly fetch the latest spec from @heyapi.dev or @scalar.com with a dead simple syntax.

Hello, Angular 🅰️ Thanks to our incredible community, v0.80.11 comes with Angular v20 support!

One word: oRPC.

📢 oRPC 1.8.0 here ▪️First-class @opentelemetry.io support ▪️Stable @trpc.io support ▪️Stable Hibernation APIs ▪️Many improvements

This rocket is powered by user feedback 👨‍🚀

New sponsor alert ⚡️ Huge thanks to @fastapi.tiangolo.com for sponsoring Hey API! @tiangolo.com was one of our earliest supporters, and now he’s backing us financially too. Exciting things ahead!

oRPC is the real deal!

Installing dependencies from both npm and GitHub Packages under the same scope? It can get messy. 😖 npm.pkg.heyapi.dev is a drop-in proxy that resolves packages from both sources. Add it to your .npmrc and let it handle those pesky scopes for you.

Zod 4 or Zod Mini? 🍿 With v0.80.0, the choice is yours. Simply set compatibility version to “4” or “mini” to generate the desired @colinhacks.com schemas. Happy parsing!

Want to see your code in products used by millions? ❤️ Contributing to Hey API allows you to do that. Plus, you’ll join this list of fine people.

Give your OpenAPI spec a little massage with v0.78.0 💆 The new parser options allow you to filter, modify, or validate your spec before it’s used by plugins. The most common transforms are available as a one liner. And they work like magic.

🎉 Cella now is a proud user (and sponsor) of openapi-ts for some much needed improvements: it generates clean, shared zod schemas for frontend validation and an sdk to reduce boilerplate code. Next one for Cella is perhaps MCP through our OpenAPI spec ?! 🤠 github.com/hey-api/open...

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. 🎶

End-to-end request validation available in v0.77.0. ✅ And if you’re wondering, yes, you can use different libraries to validate requests and responses.

The best user feedback we’ve received in a while 🚑 “We love Hey API. It singlehandedly saved our company during our migration to TypeScript.”

Congratulations on 10,000 GitHub stars @scalar.com 🎉

🚀 oRPC v1.4.0 is out! 🔁 Dedupe Requests Plugin 🧃 Buffered Mode in Batch Plugin 👋 Hey API Integration 🪣 AWS Lambda Adapter 🔍 TanStack Query Integration 🔢 Bracket Notation Parsing Update 📬 inferRPCMethodFromContractRouter 🔧 Router → Contract Utilities 🛠️ route.spec Override github.com/unnoq/orpc/r...

The latest version of xink api router now supports creating a typed api client, using generators like @heyapi.dev Sprinkle some schema on your endpoints, set an OpenAPI path, and generate the client.

Expanded Filters 🧹 v0.66.1 added support for more filters. These can be used to easily exclude deprecated fields from your output.
