Bookmark Cleaner
Chrome still doesn't let you export bookmarks as JSON natively. The built-in manager only does HTML. I wanted something minimal — no UI, no config, no data leaving my machine. So I built a small extension: click the toolbar icon, get your full bookmark tree as a JSON file. Two permissions (bookmarks + downloads), works offline, a few KB total.

What it does
How many of your bookmarks still work? Probably fewer than you think. Bookmark Cleaner scans every bookmark in your browser, detects dead links — 404s, timeouts, server errors — and lets you review and delete them in bulk. One-click scan of your entire bookmark library Review dead links before deleting — nothing is removed without your approval Zero data collection. Nothing leaves your browser. Ever. Lightweight. Vanilla JS. No frameworks, no bloat. Free and open source.

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.
