protoCURL is cURL for Protobuf: The command-line tool for interacting with Protobuf over HTTP REST endpoints using human-readable text formats - qaware/protocurl
ProtoCURL is a command-line tool that functions as curl for Protocol Buffer data. It enables developers to interact with protobuf-based services and APIs directly from the terminal, similar to how curl works with HTTP… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Hey HN, I built uncurl.dev to scratch my own itch: I kept getting curl commands in API docs, bug reports, or Slack messages and wanted a quick way to visualize, run, and debug them without firing up Postman or writing code to dissect them. It was also sometimes painful to create a test page specifically for non-tech users to consume an API. I originally vibe-coded this over a weekend just to make it easier for myself to debug API requests shared as curl commands. It slowly grew into something I found surprisingly useful in my workflow, so I decided to clean it up and share it. uncurl.dev…

Hi, I created httpdbg, a tool for Python developers to easily debug HTTP(S) client requests in Python programs. I developed it because I needed a tool that could help me trace the HTTP requests sent by my tests back to the corresponding methods in our API client. The goal of this tool is to simplify the debugging process, so I designed it to be as simple as possible. It requires no external dependencies, no setup, no superuser privileges, and no code modifications. I'm sharing it with you today because I use it regularly, and it seems like others have found it useful too—so it might be…

Hiya HN! Just released Artillery Probe - a Swiss army knife for testing HTTP from the CLI. Think mini-curl with better UX for common use-cases, plus a couple of extra features. Would love for you to try it and give some feedback! https://www.artillery.io/blog/swiss-army-knife-for-http-testing and: npm install artillery@latest What does it do? - First of all, it's a HTTP client! It does all the usual stuff you'd expect from a HTTP client... HTTP methods, request bodies, custom headers, forms, Basic Auth etc. - Got some JSON or XML back? It'll pretty-print it, and syntax…

Hey all, As a CEO of a growing startup I don't get to code as often as I like and when I do, I try not to annoy my team with my terrible code :) So to scratch the itch, I've built some of side projects related to what our company does. The latest is embedcurl.com I see a lot of API docs and blogs posting curl commands that are really hard to read and I figured I could make them easier to read and add some niceties like easier copy/paste, tooltips on flags, etc. They also gracefully degrade if javascript isn't enabled back to a element. The parsing is done in Python with shlex and…

I've frequently found myself using [nvitop](https://github.com/XuehaiPan/nvitop) to diagnose GPU/CPU contention issues. The two best things about it are: - It's easy to install if I can access pip in the container - It makes a compelling screenshot (which helps me communicate with coworkers.) With those two lessons in mind: Here is Sping! Purpose: Help observe and diagnose latency issues at layer 4+ (TCP/HTTP/HTTPS) Two good things about it: - It's easy to install if you have pip.

Protobuf is a fairly simple format, but the way people are first introduced to it often doesn't speak to them. That is how it was for me at first. I tried to address that in two ways: simple visual diagrams where a picture does the work better than prose, and interaction so you can get a feel for the language and how it behaves without installing anything. Some parts of the guide run a real Protobuf compiler, bufbuild/protocompile, in the browser through WASM. It's the same compiler the buf CLI uses. Feedback welcome. Disclosure: I work at Buf, and Buf owns the domain. The guide started…
