24 alternatives to A Swiss army knife for testing HTTP from the terminal
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…
Artillery Probe is a command-line HTTP client designed for developers who need to test APIs and web services from the terminal. It handles standard HTTP operations like different request methods, custom headers… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. A Swiss army knife for testing HTTP from the terminal launched in 2022; newer entries below may have overtaken it.

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…

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…

Hiya HN! tldr: Artillery is an open-source load testing toolkit. It's cloud-native, i.e. you can scale out your test with AWS Lambda (other runtimes coming soon). There's no infra to set up or manage - you give Artillery an AWS account, and it takes care of the rest. We just released an update which includes cost reporting. Every time you run a load test, Artillery will show how much that cost in AWS Lambda fees. Blog post with a demo here: https://www.artillery.io/blog/this-load-test-cost-us-how-much The demo shows a distributed load test running in us-east-1 at 100k+…

I'd like to invite everyone to try out DontBeEvil.rip, an experimental search engine for developers. tl;dr $ alias rip="curl -G -H 'Accept: text/plain' --url https://dontbeevil.rip/search --data-urlencode " $ rip 'q=Heartbleed bug' DontBeEvil.rip is a year long experiment to see if a small team can build a developer-focused search engine that is self-sustaining on $10 monthly subscriptions. It works by only indexing high-quality resources that are relevant to developers. You won't get useless listicles because we'll never crawl them. Relevant urls are harvested from HN,…

Hi HN, Some misbehaving networks drop WireGuard packets either by accident or on purpose. Commonly the latter is done with simple DPI rules that block the handshake initiation [1], but it could be applied to other message types as well. We thought it would be great if there was tool for folks to use as a quick litmus test to see if this happening for them, without having to configure a client to send data through a random, functional WireGuard tunnel to an untrusted remote host. So we built probe.sh. How it works: - The probe.sh web app is an Elixir Phoenix app that spawns a few gen_udp…

I built this out of curiosity about what Claude Code was actually sending to the API. Turns out, watching your tokens tick up in real-time is oddly satisfying. Sherlock sits between your LLM tools and the API, showing you every request with a live dashboard, and auto-saved copies of every prompt as markdown and json.

Sharing an internal tool that accelerated my development work 10-fold, especially with API debugging. Thought fellow developers here might find it useful. As a developer, I often have trouble reproducing errors at the client end. https://intercept.rest lets me debug and monitor API requests and responses. It is similar to the Network tab in Chrome Developer Tools but works for any API: mobile apps, webhooks, frontend etc. After I shared it with a close circle of friends, they found it incredibly useful and even found new use cases, I never imagined. Been a long time lurker here and…

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…

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…

There are plenty of good tools for load testing such as JMeter, Minigun, and plenty more - but they all have their own set of options to learn. I built this one to support a simpler workflow where you just paste your curl request (or other cli command) after your `spam` config (literally just `spam -r 2 -- curl www.google.com). It's pretty barebones but I'm 100% going to use it in my day to day - figured I'd share it here if it helped anyone else!

I wrote this small client to read hackernews from my favorite editor. It's currently using an external HTTP API [0] but I'm working on my own proxy [1]. I'd love to actually scrape and cache all the info I need using lisp. However, my time constraints are keeping me away of that goal. I could definitely use some help here! :) I'm also planning to add support for comments and posting new things. Any feedback is highly appreciated! Thank you!

A simple Go-based HTTP proxy designed for detailed inspection of requests and responses. It logs traffic to the console with colorization, automatic decompression, and formatting for common content types, while remaining transparent to the client application. Ideal for debugging API interactions, understanding middleware behavior, or simply getting a clear view of HTTP traffic flow with jq-like pretty-printing & colorization of request/response. Automatically redacts parts of Authorization header to avoid token leakage.
