24 alternatives to Extract HTTP info from integration tests to create Swagger docs

https://github.com/lazywithclass/swaggins It works by looking at the request and extracting the relevant information to populate the Swagger JSON file. I've wrote it to go with contract testing (http://martinfowler.com/articles/microservice-testing/#testing-contract-introduction), but it can also work with normal HTTP based integration tests. Any suggestion / opinion is welcome.

Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Extract HTTP info from integration tests to create Swagger docs launched in 2016; newer entries below may have overtaken it.

    Apidog▲570

    Development 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 This fragmented approach leads to outdated API specs and chaotic collaboration.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.

    Hey HN, we’re building an open specification that lets agents discover and invoke APIs with natural language, built on the OpenAPI standard. agents.json clearly defines the contract between LLMs and API as a standard that's open, observable, and replicable. Here’s a walkthrough of how it works: https://youtu.be/kby2Wdt2Dtk?si=59xGCDy48Zzwr7ND. There’s 2 parts to this: 1. An agents.json file describes how to link API calls together into outcome-based tools for LLMs. This file sits alongside an OpenAPI file. 2. The agents.json SDK loads agents.json files as tools for an LLM that…

    I frequently face numerous challenges when working with third-party APIs - error handling, logging, caching, retries, mocking, and more. I spent hours making them work, so I created an app to automate integrations. Currently, the platform offers the following functionality: - Set up services with multiple endpoints: Configure caching, retries, mocking, response transformation, and fallback responses. - Define authentication:- Real-time Swagger/OpenAPI integration: Test your endpoints directly in the browser. - Handy code snippets: Easily copy and paste requests. Feedback needed!

    Hey HN, It will be more of a "How I released my API without managing a website, servers, users, and payments. With 0$ up-front cost" Over the past year, I have come up with a plan of how I could release my own product without having to deal with managing users and/or dealing with payment processing. It is a 3 steps procedure: 1. Make an API that solves a problem 2. Deploy it with a serverless architecture 3. Distribute through an API Marketplace That took me about 2-3 days to develop an API using Flask, deploy it via Zappa on AWS, and release through RapidAPI. Source code of API:…
