Try clearing filters or adjusting your search — most categories have dozens of tools once you widen the net.
The utilities that land on every developer's toolbar: JSON and XML formatters, base64 and URL encoders, regex tester, JWT decoder, hash generators (MD5 through SHA-512), HTML entity encoder, CSS and JS minifiers, SQL formatter, diff checker. Everything runs in your browser, so you can paste production data, API keys, customer identifiers, and JWT tokens without them ever touching a remote server. That matters when you are working under SOC 2, HIPAA, or any policy that prohibits pasting business data into public web forms. Tools auto-detect common formats, syntax-highlight output, and offer one-click copy. The keyboard shortcut (Ctrl/Cmd+K) opens a fuzzy search across every utility. Each tool keeps its last few inputs in local storage so you can bounce between tabs without losing work. Nothing is logged, sent, or analyzed. Close the tab and the data is gone.
Yes. All processing happens locally in your browser. No data is sent to any server, making these tools safe for API keys, tokens, database queries, and production code.
Yes. Once loaded, all dev tools work without an internet connection. This makes them reliable for use in restricted network environments or during travel.
The formatting and syntax tools support all major languages including JavaScript, TypeScript, Python, Go, Rust, Java, C#, SQL, HTML, CSS, and more.
