About
Built for developers, by WellFriend
WellFriend DevTools is a clean, open-source toolbox for everyday developer tasks.
What is DevTools?
A focused set of browser-based utilities for formatting, decoding, hashing, and inspecting data. Everything runs in your browser - nothing is sent to any server except the network tools, such as HTTP headers and DNS lookup, which require server-side requests.
Why we built it
Most developer tools are cluttered with ads, require accounts, or run your data through third-party servers. DevTools keeps it simple: open source, no signup, no tracking.
Part of WellFriend
DevTools is part of the broader WellFriend suite, alongside PDFTools, a toolkit for PDF and file workflows.
