24 alternatives to Multiple – Load test any API with JavaScript and NPM packages
Hey HN, I wanted a better load testing solution – so I built one with my team at Multiple. We just opened early access and would love to get your feedback. We created Multiple to solve three challenges with existing tools: 1. Limited scripting capabilities. XML or GUI-based scripting can only test basic scenarios. Existing code-based tools struggle with auth, generating synthetic data, and testing anything other than HTTP requests. We went with JavaScript for ease of use, versatility, and integration with existing developer workflows. 2. Cannot use existing libraries or code. Instead of…
Multiple is a load testing tool that uses JavaScript and NPM packages to test APIs and services. It lets developers write test scripts in JavaScript rather than XML or proprietary languages, and reuse existing code and… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Multiple – Load test any API with JavaScript and NPM packages launched in 2023; newer entries below may have overtaken it.

Apidog▲570Development teams often struggle with using multiple tools like Postman and Swagger for API design, development, and testing. This fragmented approach leads to outdated API specs and chaotic collaboration. So we built Apidog: a single, unified API platform for team collaboration. It has a beautiful interface that makes it easy to create API spec, generate request data from API spec, validate responses, create mock data, orchestrate test scenarios, and publish API documentation. Apidog = Postman + Swagger + Mock + JMeter.

Hi HN! Thanks for your attention to my post. It was a big challenge to run most of Node.js packages in browser, fast moreover. Virtual File system, resolve import/export. I got cold many times, depressions, burned out, yet still alive and finished it. Many guys helped me with an advice. Many users give a lot of positive feedback. There are 200,000 monthly unique users. I work full time now because of the freemium business model. To be honest - I am happy after many years of hard work.

Hello HN! I'm the creator and solo developer of Extension.js, a development tool for browser extensions with built-in support for TypeScript, WebAssembly, React, and modern JavaScript. Developers use it to spend less time configuring the compilation config or learning new frameworks and more time actually writing code. Most projects similar to Extension.js rely on some sort of abstraction or configuration to get started, making the initial development process slow given the extra learning curve and setup guidelines. By using Extension.js, adding the package to your npm scripts is all it…

Hey there HN! I just wrapped up an all-day documentation spree for Instant API, a JavaScript framework for easily building web APIs that implements type safety at the HTTP interface. It uses a function-as-a-service approach combined with a slightly modified JSDoc spec to automatically enforce parameter and schema validation before HTTP requests make it through to your code. You just write comments above your endpoint functions and voila, enforced type safety contracts between your API endpoints and your developers. OpenAPI specifications are generated automatically as a byproduct of simply…

Please meet Loadjitsu, my weekend project, years in the making. Over the years while building different apps and sites, I always felt that I need a modern load testing software.Tools like JMeter, ab are not very easy to use and it seems innovation in load testing which is a crucial part of any software release cycle has been ignored. This is my third attempt at making Loadjitsu, I am so glad that I can finaly release this. A bit more about the software 1. Powered by golang you can run load tests for tens of thousands of connections per second on very average hardware. 2. Cross platform, run…

Hey HN! We do a lot of frontend testing, and one thing we find frustrating is the limited tooling available to observe how a URL renders on different viewports/devices simultaneously. For example, we can use Chrome Inspector's "Device" previews, but we run into the following: - Chrome doesn't keep those devices/viewports up to date, and adding new ones is pretty annoying (we've open sourced our collection of 180+ viewports/dimensions under MIT). - You can’t see multiple viewports at once (and it’s cumbersome switching back and forth) - When you notice a problem, there's no…
