Really good SDKs from OpenAPI

  1. 1HN

    Hi 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…

    Hi 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…

    Hi 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,…

    Hi 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…

    Hey, I'm Martyn and I recently joined Zuplo. OpenAPI is a huge part of what we do, but getting a document up to scratch out of the gate, especially if you're not super well versed in the actual specification and what you should use and when. So we built a suite of tools to help with this called Rate My OpenAPI. It will score your OpenAPI document out of 100, as well as giving you individual scores in 4 key areas; completeness, SDK generation, security and documentation. Along with the score, you also get details of what the issues, or errors are, as well as guidance on what they actually…

    Hi It's Logan (op) and David, we are launching our first open source Python SDK generator with other languages to come :) We built this because we believe that the OpenAPI Generator project is a mess and simply doesn't work for most users (us included). Additionally, proprietary generators miss the mark for complex use cases, and restrict developers from doing what they do best: writing code. On top of all that they force you into proprietary configuration layers for many desirable features which increases vendor lock in and pulls you further away from your API spec as the source of truth.…

    TL;DR- Libninja will generate world-class client libraries for you, without you needing to fiddle with openapi-generator, maintain build pipelines, and so forth. If you just want Rust, reach out, and I'll create your client library at no cost, because I want to help Rust's ecosystem grow. -- Hi HN, I got into Rust in a big way about 9 months ago. While the language is quickly maturing, one large gap in the ecosystem is immature or non-existent client libraries for common API services like Plaid, Stripe, Twilio, Github, Slack, and so on. The existing openapi-generator templates create Rust…
