Every developer knows the frustration: you need to quickly format some JSON, decode a Base64 string, or test a regex pattern. You end up with dozens of browser tabs open, each for a different task. What if there was a single swiss army knife for developers that handled all of these tasks in one place?

That's exactly what Dev Toys provides — a comprehensive developer toolbox with 30+ utilities for everyday coding tasks. Whether you're formatting JSON, comparing text, testing regexp, or generating UUIDs, dev toys has you covered. No installation, no signup, just open your browser and start working.

What Makes a True Swiss Army Knife for Developers?

The term "swiss army knife" gets thrown around a lot in tech, but what actually makes a developer toolbox worthy of that name? A true devtoys-style toolkit needs several key qualities:

1. All the Essential Tools in One Place

A real swiss army knife for developers doesn't make you hunt for tools. Dev toys includes everything you need for daily development work: data converters, encoders, formatters, generators, text utilities, and testing tools. One URL, 30+ utilities.

2. Instant Availability

When you need to quickly decode a JWT or format messy JSON, you don't want to download software or create accounts. Devtoys web runs entirely in your browser — open the page and start working immediately.

3. Works Anywhere

Your swiss army knife should work whether you're on your main workstation, a colleague's laptop, or a random computer. Dev toys runs on any device with a modern browser — Mac, Windows, Linux, even Chromebooks.

4. Privacy by Default

Developers often work with sensitive data: API keys, tokens, production configs. A true developer toolbox processes everything locally in your browser. Your data never leaves your machine.

The Essential Dev Toys Toolkit

Here's what makes devtoys the go-to swiss army knife for developers. These are the tools you'll reach for every day:

Formatting JSON (and Other Data)

Formatting JSON is probably the most common developer task. Dev toys provides a full-featured JSON formatter that beautifies, minifies, validates, and syntax-highlights your data. Also includes formatters for XML, SQL, YAML, and HTML.

Comparing Text and Finding Differences

Need to spot what changed between two config files or API responses? The text comparer shows side-by-side diffs with highlighting. Comparing text is essential for debugging and code review.

Testing Regexp Patterns

Regular expressions are powerful but tricky. The regex tester lets you test patterns in real-time with match highlighting, capture groups, and flag options. Testing regexp has never been easier.

Encoding and Decoding Data

Dev toys includes encoders for every common format: Base64, URL encoding, HTML entities, JWT tokens, and more. Stop searching for random websites — the devtoys developer toolbox has them all.

Converting Data Formats

Transform data between formats with converters for JSON ↔ YAML, XML ↔ JSON, JSON → CSV, and number bases. The swiss army knife approach: one tool, many conversions.

Generating IDs and Passwords

Need a UUID? A secure password? A hash? Dev toys generators include UUID generator (v1, v4, v6, v7), password generator, and hash calculator for MD5, SHA-1, SHA-256, and SHA-512.

Real Developer Workflows with Dev Toys

A swiss army knife for developers isn't just a collection of tools — it's how those tools work together. Here are workflows that devtoys handles seamlessly:

API Debugging Workflow

You get a messy JSON response from an API. With dev toys, you can format the JSON, extract specific data with JSONPath, compare it against expected output, and export to CSV — all without leaving the toolbox.

1. Paste messy JSON into the JSON formatter
2. Query specific fields with JSONPath tester
3. Compare versions with text comparer
4. Export to spreadsheet via JSON → CSV converter

Config Management Workflow

Working with Kubernetes YAML? Docker Compose? CI/CD configs? Devtoys handles the entire workflow:

1. Convert between YAML and JSON with YAML converter
2. Validate syntax and structure
3. Diff config versions with text comparer
4. Parse cron schedules with cron parser

Security & Auth Workflow

Debugging authentication issues? Dev toys provides the complete security toolkit:

1. Decode JWT tokens with JWT decoder
2. Parse SSL certificates with certificate decoder
3. Generate secure credentials with password generator
4. Calculate file hashes with hash generator

Why Developers Choose Dev Toys

There are many developer utilities out there. What makes devtoys the preferred swiss army knife for developers?

Zero Friction

No downloads. No accounts. No permissions. Dev toys works instantly in any modern browser. When you need to quickly format JSON or test a regex, friction matters. Developer toys removes it entirely.

Privacy-First Architecture

All dev toys processing happens in your browser using JavaScript. Your data never hits a server. This means you can safely use the devtoys toolbox with production data, API keys, tokens, and sensitive information.
