DevToolBox - 24 private, browser-based tools for developers

by•
A free collection of 24 developer tools for JSON, JWTs, PDFs, regex, Base64, hashing, SQL formatting, diffs, and more. Tool inputs run client-side in the browser, so files, tokens, JSON, and code are not uploaded. No signup required.

I built DevToolBox because I kept using small developer utilities for things like JSON, JWTs, diffs, regex, PDFs, Base64, and hashing, but did not always want to paste sensitive data into random server-side tools. The main goal is simple: quick browser-based tools where the input stays client-side. JWT decoding is the clearest example, since tokens can contain data you probably do not want to upload. This is intentionally not a big platform or SaaS launch. It is a free utility collection for everyday developer work. Feedback is welcome, especially on which tool page feels like the strongest entry point and whether the privacy messaging is clear.
