As developers, we all have that folder of bookmarked utilities we rely on to get through the day. Whether it's diagnosing why an authentication token is failing, comparing two massive config files, or just trying to make a button look good without writing 20 lines of CSS, having the right tool at your fingertips is a massive time-saver.
I've been continually expanding DevSmith Tools with exactly these kinds of utilities. Every tool is designed to run entirely locally in your browser so your sensitive data is never transmitted anywhere.
Here are 5 more utilities from the collection you should definitely check out:
1. 🔐 JWT Decoder
The Struggle: You need to inspect a production JSON Web Token (JWT) to verify user roles or expiration dates, but you absolutely cannot paste it into a random online decoder.
If you work with modern web apps, you're constantly dealing with JWTs. The JWT Decoder instantly unpacks the header and payload safely on your own machine, allowing you to debug auth flows with peace of mind.
2. 📝 Text Diff Tool
The Struggle: Trying to figure out exactly what changed between two massive JSON payloads or environment configuration files.
While git diff is great for source code, sometimes you just need to quickly compare two raw text blocks side-by-side in your browser. This tool highlights additions and deletions instantly, making it incredibly easy to spot rogue commas or mismatched values.
3. 🎨 CSS Box Shadow Generator
The Struggle: Writing
box-shadow: 0px 4px 10px rgba(0,0,0,0.1);from scratch, refreshing the page, and realizing it looks terrible.
A visual box shadow generator lets you tweak the X/Y offsets, blur, spread, and color with intuitive sliders. Once it looks perfect, simply copy the generated CSS directly into your stylesheet.

4. 🧮 Base Converter
The Struggle: Jumping between binary, octal, decimal, and hexadecimal when doing low-level programming or reverse-engineering data.
This Base Converter allows you to paste a value in one base and instantly see the equivalent in all the others. It's an indispensable tool for systems programmers and security researchers.
5. 🧹 HTML Formatter
The Struggle: Copying HTML from a CMS or scraping a webpage, only to end up with a massive, unreadable block of single-line code.
An HTML Formatter takes that mess and instantly pretty-prints it with proper indentation. It turns minified spaghetti code into something human-readable and ready for debugging.
