24 alternatives to OpenAPI Zapier Generator

Hey HN! We've developed a way to turn API specifications, like OpenAPI 3.0, into Zapier Triggers and Actions for you to automate parts of an app, with the added benefit of SDK generators. Documenting endpoints sucks. What sucks more is a clunky interface to let nontechnical use your app or outdated/nonexistent SDKs for technical people to set and forget. This project originated from my cofounder and I having to make Zapier.com and Make.com apps frequently while not getting what we wanted out of https://openapi-generator.tech/docs/generators/zapier/. Our…

OpenAPI Zapier Generator converts API specifications in OpenAPI 3.0 format into Zapier Triggers and Actions, enabling automation within applications. It is designed for developers who frequently build Zapier and… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    For the past few months we’ve been building Trigger.dev and can now share our beta with you: https://github.com/triggerdotdev/trigger.dev. Trigger.dev is an open source platform that makes it easy for developers to create event-driven background tasks directly in their code. You write workflows using our SDK, and can view all the runs in our web app. Why we built this: - We found current workflow / automation tools like Zapier and n8n are good for simple tasks, but not for more advanced use cases. - Dropping down into code in these tools is just not a great…

    Hey HN! We've developed OpenAPI AutoSpec, a tool for automatically generating OpenAPI specifications from localhost network traffic. It’s designed to simplify the creation of API documentation by just using your website or service, especially useful when you're pressed for time. Documenting endpoints one by one sucks. This project originated from us needing it at our past jobs when building 3rd-party integrations. It acts as a local server proxy that listens to your application’s HTTP traffic and automatically translates this into OpenAPI 3.0 specs, documenting endpoints, requests, and…

    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…

    Hey HN! We launched Zapier way back in 2012 on HN: https://news.ycombinator.com/item?id=4138415 and thought we'd return home to announce something special and hopefully exciting :) We are trying to finally live up to the "API" in our name with Zapier's first universal API: Natural Language Actions – https://zapier.com/l/natural-language-actions API docs – https://nla.zapier.com/api/v1/docs (to be fair, we have published APIs before that can access Zapier data, but never before one devs can use to directly call the 5k+ apps /…
