    Gitcasso – Syntax Highlighting and Draft Recovery for GitHub Comments▲33

    I built a browser extension called Gitcasso which: - Adds markdown syntax highlighting to GitHub textareas - Lists every open PR/issue tab and any drafts - (Optional, unimplemented) autosaves your comment drafts so you don’t lose work I made it because I was impressed by https://overtype.dev/ (a markdown textarea syntax highlighter) which went big on here on HN a few weeks ago, and it seemed like a perfect fit for a GitHub browser extension. Keeping up with changes on upstream GitHub would normally be a pain, but with with Playwright and Claude Code it seemed possible for…

    Comparelists.org – Instantly Compare Two Lists, Find Differences▲10

    Hey HN, I got tired of manually comparing two lists (think: emails, product SKUs, code, whatever) and built CompareLists.org to make it painless.

It handles thousands of lines, works right in your browser (no data leaves your device), and you can export results as CSV/TXT/JSON. There are options for case sensitivity, whitespace, and more. It’s free and there’s no signup. I’d love for you to try it out and let me know what you think—or if there’s a feature you…
