24 alternatives to Stripe-quality API client libraries with a single button click
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…
Libninja generates high-quality API client libraries from OpenAPI specifications with a single click, eliminating the need to configure openapi-generator or maintain build pipelines. It targets developers who need… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Stripe-quality API client libraries with a single button click launched in 2022; newer entries below may have overtaken it.

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, I made a bridge (https://github.com/fzyzcjy/flutter_rust_bridge v2.0.0) between Flutter and Rust, which auto translates syntaxes like arbitrary types, &mut, async, traits, results, closure (callback), lifetimes, etc. The goal is to make a bridge between the two, seamlessly as if working in one single language. Then, as an example, I showed how to write Rust applications with GUI by utilizing Flutter. That is discussed in the link in details. To play with it, please visit the GitHub repo, or refer to the end of the article for detailed folders and commands. When I…

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…

You write a standard solution, just like on LeetCode, and run it through the CLI. It identifies the problem by ID or title, executes your code against local test cases, and shows the result. It currently supports around 1.4k problems and multiple languages, including Python, C++, Rust, Java, Go, TypeScript, Swift, and others. The project is still an MVP. System design, SQL, and concurrency problems are not supported yet, but support for more problem types is planned. Made in Haskell!

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…

We built an open-source tool that scans your codebase and generates OpenAPI docs in minutes. Right now it supports Rails, Go, Python, and NodeJS frameworks, and we will keep adding more. It picks up routes, params, request bodies, and models directly from the code and outputs a clean OpenAPI spec you can drop into your workflow.

Initially I started building this for my own projects. The main goal was to define a unified "blueprint" allowing me to develop multi-platform apps using the same code, without code generation. I wanted to be able to develop the same functionality on web, desktop, cli, server, mobile, whatever... I've been able to achieve this by relying on TypeScript, a 4-layer architecture (UseCase => App => Product => Target) and dependency injection. This mechanism allows me to use whatever tech stack I want, provided the good adapters are developed. For instance, I have pre-built ones : node express…

I built this because I wanted to make outbound and accept inbound HTTP/3 and raw QUIC connections from ordinary Node.js code, without building Node from source or putting everything behind a reverse proxy. Repo: https://github.com/currentspace/http3 npm: https://www.npmjs.com/package/@currentspace/http3 It’s a native package around Rust/quiche. It supports both client and server APIs, I'm using it in a couple of projects: creating raw QUIC streams, datagrams, custom ALPN, session behavior, and HTTP/3 client work from Node. I've…

I made an open source, MIT license Typescript library based on some of the latest research that generates prompt injection attacks. It is a super minimal/lightweight and designed to be super easy to use. Keen to hear your thoughts and please be responsible and only pen test systems where you have permission to pen test!

Hey HN, Sagiv from liblab is here. We've been deep in the world of API tooling for years at liblab, primarily focusing on generating SDKs and documentation from OpenAPI specs. Recently, we kept running into a recurring frustration: connecting AI tools to existing APIs is way more complex than it should be. You start with a simple goal – let an LLM talk to your API – and suddenly you're neck-deep in spinning up infrastructure, wrestling with authentication, and writing a ton of custom glue code just to translate natural language into structured API calls. Then you have to maintain it all. To…

Hi HN! I built rapid-rs to solve a problem I kept hitting: setting up a new Rust web API requires wiring together lots of crates and boilerplate. : FastAPI's developer experience + Spring Boot's conventions, with Rust's performance and type safety. : - One command to scaffold: `rapid new myapi` - Auto-configuration: DB, logging, CORS work out of the box - Type-driven validation: Compile-time + runtime guarantees - Auto-generated OpenAPI/Swagger UI - Built on Axum, so you can use Axum patterns when needed It's early stage but functional. Would love feedback from the HN community! GitHub:…
