What it does
ToolCrux is a collection of 42 developer and utility tools that run entirely client-side. No accounts, no data sent to servers. What makes it different: • Tool chaining — output from one tool flows into the next • Shareable state — share any tool's state via a short link • Embeddable — embed any tool on your site with one iframe tag • 1,400+ SEO landing pages for quick answers (timestamps, hashes, conversions) Built with vanilla JS, Cloudflare Workers, and zero frameworks.
Chain 55+ free browser tools into workflows. JSON formatter, password generator, DNS lookup, image compressor, and more — no signup, no uploads, shareable links.
Paste once, run a multi-step workflow, share the exact result with a link — no signup, no uploads, everything runs in your browser. Pick a workflow below and run it in one click — no copy-pasting between tabs. Decode JWT tokens and format the payload for easy inspection. Count words, characters, sentences, and paragraphs in real-time. Beautify, minify, and validate JSON with syntax highlighting. Run multi-step pipelines without switching tabs — output flows automatically. Share tool results with a link — recipients see your exact input and output. Save your most-used tools, pick up where you left off — no hunting through menus. Everything runs in your browser.…from toolcrux.com

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
