Hacker News API SDKs → Code Generation in Rust2023 · hacker-news.sideko.dev · ▲39Hi Hacker News! Patrick and Elias here. We built an SDK / Documentation generator for REST APIs. The link included shows the shiny output of our system: the docs! We generated 5 SDKs and docs from the Hacker News OpenAPI we found on GitHub. If you write code in Python, Typescript, Go, Ruby, or Rust, we’d love for you to try an SDK out! If you want to generate SDKs for your own API try our tool here: https://github.com/Sideko-Inc/sideko We are both software engineers, and we built this tool because we were spending too much time writing API integrations, supporting…
Sideko – Hybrid deterministic/LLM generator for API SDKs and docs2025 · github.com · ▲26Hi HN, I’m Patrick. Elias, Kevin, and I are building Sideko (https://sideko.dev), a new type of code generator for building and maintaining API client SDKs from OpenAPI specs. Traditional SDK generators rely on static templates that produce rigid, machine-generated code. When the API changes, these generators completely overwrite the SDK, destroying any custom modifications developers have made. The result is brittle code that looks artificial and requires constant manual rework. Our approach uses structured pattern matching queries instead of templates. These queries analyze the…

An opinionated and statically-typed TypeScript SDK generator2022 · easysdk.xyz · ▲81Hi Hacker News! My name is Sagar, I’m working on a startup called Speakeasy - we’re making all APIs self-service. The platform is currently in beta, but we’re independently launching this tool which you can use to generate language-idiomatic, statically-typed TS SDKs from any public OpenAPI schemas. We hope to continue iterating on this to give devs a way to easily generate high fidelity client SDKs for all the major languages. Inspiration for this product is from past experiences struggling with OpenAPI. I was originally optimistic about using the OpenAPI tools to build out our offering,…
Turn OpenAPI to Universal TypeScript SDKs2024 · speakeasyapi.dev · ▲27Hi HN! We’re excited to share our new code generator that lets you ship high-quality TypeScript SDKs, that your users will love, from your OpenAPI documents. Our ongoing goal is to help you build one SDK that runs anywhere modern JavaScript runs. This includes new runtimes like Deno and Bun in addition to the ever-popular Node.js. Additionally, the popularity of AI has meant server-sent events and file streaming are also commonplace - we wanted to cover these use cases too. This explosion in new runtimes and ways of interacting with APIs shifts cognitive burden on API developers often having…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Tapflow 2.0▲1,125We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
