API URL fuzzer for API hackers

    Hello HN! I became frustrated with the unpredictible/poor match quality and opaqueness of "relevance scores" in existing fuzzy and fulltext search libs, so I tried something different and this is the result. The main selling point is the result quality / ordering, with best-in-class memory overhead and excellent performance being bonuses. The API is pretty stable at this point, but looking for feedback before committing to 1.0. TL;DR The test corpus is a 4MB json file with 162k words/phrases, so give it a second for initial download. You can also drag/drop your own…

    I recently dipped my toes into bug bounty hunting and finding security flaws in web applications. As a friend of UNIX shells I was building a repertoire of command line tools to make and analyze HTTP requests. Fortunately there are already many suitable tools like curl, jq, different fuzzers and some really nice tools for specific tasks by Tom Hudson [1]. However, I disliked that the existing fuzzers were monoliths where I had no easy way of creating custom behavior or analyses. They commonly do a multitude of things: Create multiple requests using one or more wordlist, sending the request,…

    Hey HN, This is Jan, founder of Apify, a web scraping and automation platform. Drawing on our team's years of experience, today we're launching Crawlee [1], the web scraping and browser automation library for Node.js that's designed for the fastest development and maximum reliability in production. For details, see the short video [2] or read the announcement blog post [3]. Main features: - Supports headless browsers with Playwright or Puppeteer - Supports raw HTTP crawling with Cheerio or JSDOM - Automated parallelization and scaling of crawlers for best performance - Avoids blocking using…

    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…

    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…

    It's inspired by this comment I made: https://news.ycombinator.com/item?id=26599746. I actually saw several comments with HTTP URL posted, and that was the only one I bothered to comment on. So I thought that this is something better suited for bots than human. I hacked this together over yesterday and today: https://github.com/fishy/https-bot. Basically it uses the Firebase API (https://github.com/HackerNews/API) to find comments with HTTP URLs in them, try the HTTPS version, compare the contents, post back a comment if the contents are…

    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.

    G’day Hacker News, I’m Simon Gurcke, the sole founder of Apitally (https://apitally.io). I’m building a simple API monitoring and analytics tool for Python / Node.js apps. It helps users understand API usage and performance, spot issues early and troubleshoot effectively when something goes wrong. Features include: - Dashboards: Provide insights into API traffic, errors, performance and consumers. - Request logging: Opt-in and highly configurable in terms of what data is logged. Users can drill down from aggregated metrics to individual requests (proven to be super helpful…

    Select anything on a website. If it is part of a table or a list, you get a URL which you can GET for a JSON representation of that list or table. Basically we are making an API for every website whether they like it or not.
