Products that do what Convoy Playground (For testing ingest and egress webhooks) does
Hello Hacker News! We've been working on Convoy Playground [0], a tiny proxy and debugging tool which makes testing webhooks a breeze. If you've ever struggled with configuring or troubleshooting webhooks, we believe this tool will be a game changer for you. Convoy Playground provides a simple, intuitive, and powerful interface for testing, debugging and replaying webhooks. You can send HTTP requests to your specified endpoints, view and analyze the response in real-time, and even replay the requests as needed. The inspiration for this project came from the countless hours we've spent…

Hey Friends, Convoy is an open-source webhooks gateway. Webhooks continue to be hard at scale, and large teams require consistent tooling for inbound & outbound webhooks. Convoy enables developers to securely send, receive and manage millions of webhooks reliably with features like retries, rate limiting, circuit breaking, customer-facing webhook logs, zero downtime secrets rotation and more. Since our initial launch [0], we've learned a lot about our users and made several important improvements we are excited to share: - We are now a webhooks gateway! Akin to API Gateways that sit at the…

Hi everyone, I recently published a small open-source project. It’s a minimal network packet analyzer written in Go — designed more like a learning toy than a replacement for Wireshark. It currently supports parsing basic protocols like TLS, DNS, and HTTP, and includes a tiny fuzzing engine to test payload responses. You can inspect raw packet content directly from the terminal. The output is colored for readability, and the code structure is kept simple and clear. The entire program is very small — just about 400 lines of Go code. I know it’s not anywhere near Wireshark’s level, and I still…

Hello HN, We’d like to show you our project — Nohooks[0]. The aim is to add webhooks to platforms that do not natively support webhooks. We really believe many APIs can provide a better developer experience by providing webhook notifications to enable us to automate more things. Nohooks works by intelligently polling the integrated platform's APIs, determining if a change has occurred, and generating webhook events. Nohooks currently supports webhooks from Notion’s Databases, Render’s Services & Deployments, and DigitalOcean’s Droplets. We will add more in the coming days and improve the…

Hi HN! Last year, I built LocalCan app in which you can develop apps using .local domains and Public URLs. Although it allows for testing webhooks too, I wanted to give back and create a free online tool specifically for that purpose! And so, I've made Webhook.cool Simply use your unique webhook URL to send any webhook to it from services like Shopify, Slack, Mailchimp, Trello, GitHub, PayPal, Discord, and Jira. Give it a try and let me know how if you have any feedback.

Inspired by Compiler Explorer and other playground/fiddle websites like jsfiddle, db-fiddle, Go playground, and Rust playground, I thought it would be cool to have a playground for nearly any program so I've been working on Program Explorer: a playground for running programs from containers. I am inspired by these playgrounds because they are great educational tools for quickly experimenting and as communication tools by sharing shortlinks that reproduce bugs for instance. I would love for every open source project that publishes a container to get their own playground for free. I'm…

I wrote this tool during an internship at Narf Industries in 2023. It's a REPL that allows for quickly developing, testing, and fuzzing for HTTP request smuggling attack payloads. I started the internship having never worked with web servers, and have now found over 100 HTTP implementation bugs. I attribute this mostly to the ease of experimentation in the Garden. REPL-oriented fuzzing is just a really good interface for finding parsing bugs. It's pretty neat to able to run a differential fuzzer, categorize and display all the discovered discrepancies, then let a human pick through them and…

I built this out of frustration as I lead the development of AI features at Yola.com. Prompt testing should be simple and straightforward. All I wanted was a simple way to test prompts with variables and jinja2 templates across different models, ideally somthing I could open during a call, run few tests, and share results with my team. But every tool I tried hit me with a clunky UI, required login and API keys, or forced a lengthy setup process. And that's not all. Then came the pricing. The last quote I got for one of the tools on the market was $6,000/year for a team of 16 people in a…

Hey HN. My name's Matteo and I'm currently a SWE @ Twilio. 1 day at stand-up the question came up if there was an open source solution to something like https://www.runscope.com. I found it super interesting that there was no artillery.io-like YAML/DSL solution out there. So I built one. Why i think this is cool: 1. Companies today run a ton of microservices for event-driven systems. Asserting on the ingress/egress out of a system might not be covered fully by HTTP. I've setup a plugin interface so that I can implement assertions on stuff like file buckets, DBs, queues,…

Hey HN, We made an Envoy Proxy playground [0] so we could test out our Envoy configs directly in the browser. This is based on Julia's work with Nginx Playround. [1] We forked that repo and added more Envoy to it. [2] Check it out! [0] - Envoy is a popular programmable proxy similar to Nginx or HAProxy that is popular with cloud-native setups: https://www.envoyproxy.io [1] - https://nginx-playground.wizardzines.com [2] - https://github.com/apoxy-dev/envoy-playground
