Best alternatives to Prism.Tools in 2026
Every developer keeps a mental list of little tools they reach for constantly: format this JSON, test this regex, decode this JWT, generate a QR code. Usually that means bouncing between a dozen different websites, several of which quietly log what you paste in. Prism.Tools bundles over 40 of these utilities into one privacy-focused page that processes everything client-side, in your own browser — nothing you type ever reaches a server. The toolset covers the basics developers reach for daily (JSON formatter, regex tester, base64 encoder/decoder, Git command helper, HTTP status code reference, JWT decoder, password generator, hash tools) plus some extras (QR code generator, subnet calculator, CSS gradient maker, favicon creator). It's modular, has bookmarkable URLs per tool, keyboard shortcuts, and a dark mode. It relies on a handful of minimal CDN dependencies (marked.js, exifr, highlight.js, sql-formatter) rather than a full backend, and ships under a custom license that permits local or private-network hosting and modification but prohibits public re-hosting. The original Show HN post (January 2026) drew 380 upvotes and 104 comments — a solid, if not viral, reception.
