Go Faster with HeyAPI

Even in 2026, I often get challenged about the point of maintaining an OpenAPI Spec. Even when explaining the importance of planning and designing APIs, you can still get pushback. One argument that never fails is tooling integrations like frontend code generation from OpenAPI specs. Tools like HeyAPI solve real issues that developers can't ignore.

Building a modern React App using TanStack you hit many speedbumps. TypeScript types drifting from the backend contract, query keys inconsistent across apps, mutations and hooks repeated throughout the codebase, and backend changes triggering many, many frontend updates. AI is also exacerbating these issues. There is a great talk from React Miami by Delvin Dulduloa on this very topic, totally worth a watch.

Design better APIs and empower frontend teams to go faster with an OpenAPI Spec and tools like HeyAPI.

The API Roundup

API News, links, and tools from around the web

PatchBay: Find an API

A wonderful find that stumbled into my feed this week. Browse over 3000 APIs and find the right one for your project. They also have their own API and llms.text endpoints to make working with the data easier. Love projects like this.

Heimdall

With a cool name like Heimdall, why even bother finding out what it does? Just start using it. Heimdall is an HTTP client for Go that specialises in making many requests. It comes with a bunch of built-in features to control and retry failing requests. It sees all.

Talos: Open Source API Key Server

Issue, verify and revoke API keys at scale with Talos. Comes with admin and self-surface setups, built ready for cloud-native environments. Getting API keys right is hard, and Talos comes with so much built in that it makes handling them easy.

Drift

Apparently, Oxide has some of the best OpenAPI tooling in the ecosystem. While I was digging to find out if this was the case, I stumbled upon their OpenAPI tool, Drift. It detects changes between two OpenAPI docs. Classify changes as backwards-incompatible, forward-incompatible, incompatible, trivial, or unhandled. Definitely worth checking out.

Node.js 24 vs 25 vs 26 Complete Benchmark

Want to know how different versions of Node stack up? With so many APIs built with Node, it's definitely worth reviewing benchmarks for each version. Node.js has undergone some amazing changes over the last few versions. Personally, I feel like the competition from Bun and Deno lit a fire under the maintainers and community.

APIs You Won't Hate

The latest from the team at API's You Won't Hate.

Does your company build API tools?

APIs You Won't Hate is built to help the API developer community share knowledge and raise the bar for the tech we use. We're looking for more corporate backers through GitHub Sponsors to help keep the site running, pay for maintenance and server costs, and to continue our mission. If you'd like to talk about a sponsorship, reach out!

Work Sucks

Mathew reflects on the changes AI is bringing to software engineering and large organisations. Personally, I love the line "Rented Capability Is Not Owned Competence". A good reflection on the challenges we are currently facing and what to focus on moving forward.

Jentic API Scorecard

Score your OpenAPI document using a scorecard to assess its readiness for AI integrations. It scores your doc across five areas: Foundation Compliance, Developer Experience, AI Readiness, Agent Usability, Security, and AI Discoverability. An interesting tool, especially as I find more of the APIs I build being integrated into LLM workflows. Thanks for sharing, Frank Kilcommins.

Thanks so much to our members: Kin, Juxt, Brandon K, Frank, James D, Bill D, and Abdelhadi D. Your support means the world to us!
