Show HN: ToolHop – Fast, simple utilities for every workflow https://ift.tt/ArdSZbl

Show HN: ToolHop – Fast, simple utilities for every workflow ToolHop is your all-in-one browser toolbox with 200+ fast-loading calculators, converters, generators, color labs, and dev helpers. Use global search or curated categories to jump straight into the right utility, run it client-side for instant feedback, and deep-link results to your team. Whether you’re formatting copy, validating data, checking DNS, or exploring palettes, ToolHop keeps your core workflows a single tab away, and it’s entirely free, no account required. --- I built ToolHop because I was sick of the usual “free tool” bait-and-switch. Every time I needed to convert an image, compress a file, check some text, or run a quick calculation, I’d end up hitting some arbitrary limit like “10 uses per week” or a forced signup wall. It’s ridiculous how something as basic as converting a JPG to a PNG can turn into a subscription pitch. So ToolHop started as a personal frustration project: I wanted a single place with a ton of genuinely useful tools that didn’t nag, lock you out, or throttle you. Over time that grew into 200+ handcrafted tools, all fast, simple, and actually free. No trickery, no timers, no limits. As I built it, the process became about consistency and quality. I wanted the tools to feel seamless, not slapped together. That meant focusing on speed, clean UI, accurate results, and making sure each tool works instantly without friction. The goal was always the same: a site that respects people’s time. Something you can rely on whenever you just need a tool to work. If ToolHop saves someone even a few minutes of hassle, then the project did its job. https://toolhop.app November 17, 2025 at 09:28PM

Show HN: ZenPaint, a pixel-perfect MacPaint recreation for the browser https://ift.tt/JnSV4qo

Show HN: ZenPaint, a pixel-perfect MacPaint recreation for the browser I've been recreating the original MacPaint in the browser on and off for a few years. It's still alpha quality, but I'm finally ready to share it more widely. The goal was pixel-perfect accuracy, so I spent a lot of time with Atkinson's original QuickDraw source code, emulators, and my iBook G3 to get details like font rendering and the shape tools exactly right. Some technical notes: - Font rendering was surprisingly tricky; understanding the original pipeline's quirks took lots of experimentation, and avoiding canvas smoothing/aliasing required careful handling. - Written declaratively with React; performance is kept reasonable with a buffer pool and copy-on-write semantics. - You can share links to artwork from within the UI. E.g.: https://ift.tt/4AEbzSI - Mobile support was not considered here (for obvious reasons). It might still be usable on a larger phone or tablet but I have not tested this at all. There's something magical about making art within MacPaint's constraints: the 1-bit graphics, the limited resolution, the peculiar set of tools that still feel surprisingly expressive. Still some rough edges and missing features, but I'd love feedback from anyone who remembers the original. https://zenpaint.org/ November 16, 2025 at 01:21AM

Show HN: An Apache Beam batch processing clone in Rust https://ift.tt/RxjaFiu

Show HN: An Apache Beam batch processing clone in Rust I've been experimenting with Apache Beam as of late at work and found that it can be slow in Python, and more complicated to use in Java where performance is better. I decided to experiment with JetBrains' AI Assistant and build an Apache Beam clone in Rust. I appreciate any commentary or feedback! https://ift.tt/9pXcwsx November 16, 2025 at 12:16AM
