The Ultimate Developer Toolkit 2026: 5 Tools I Use Daily

There is a saying in engineering: "If you have to do it twice, automate it."

But sometimes, automation is overkill. Sometimes, you just need to format a messy JSON response, or quickly hash a password, or figure out why your Cron job didn't run at 3 AM.

For years, I relied on random Google searches for these tasks. I'd click the first result, paste my sensitive API keys into some shady website, and hope for the best.

That scared me.

So, we built Axonix Tools. A suite of client-side, privacy-first utilities designed for developers who care about security and speed. Here are the 5 tools from our collection that I personally use almost every single day.

1. The "Sanity Saver" JSON Formatter

We've all been there: a 5MB API response comes back as a single line of text. You can't read it. You can't debug it.

Our JSON Formatter is my first stop.

• Why I love it: It validates the JSON as it formats. If I missed a trailing comma in my config file, this tool finds it instantly.
• The best part: It runs entirely in your browser. I can paste production user data here without worrying that it's being sent to a server.

2. Cron Logic Generator (Because nobody memorizes syntax)

Quick: What does 0 5 * * 1 mean?

If you had to pause, you need this tool. Cron syntax is powerful but notoriously non-intuitive. I used to dread setting up scheduled tasks because a single typo could mean a backup runs every minute instead of every month.

The Cron Generator lets me visually click "Every Monday at 5 AM" and gives me the code. I copy, I paste, I sleep well.

3. TypeGen: JSON to TypeScript

This is the biggest time-saver on the list. I often work with external APIs that don't provide SDKs. Manually typing out interface UserResponse { ... } for a nested object with 50 fields is painful.

With TypeGen, I just dump the raw JSON on the left, and I get a perfect TypeScript interface on the right. It even generates Zod schemas for runtime validation, which is a requirement for modern web apps.

4. Hash Generator for Security Checks

When I'm testing authentication flows or verifying file integrity, I need hashes fast. The Hash Generator gives me SHA-256, MD5, and others instantly.

• Use Case: I often use it to quickly "salt" a string or verify that a downloaded binary matches the checksum provided by the vendor.

5. Web Performance Image Tools

This one is for the frontend devs. We all know we should be serving .webp images, but opening Photoshop to convert a single banner is friction.

I use our Image Converter to drag-and-drop my assets and get optimized web-ready files in seconds. It uses WebAssembly to crunch the pixels locally, so it's blazing fast.

Productivity isn't about working harder; it's about reducing friction. These tools remove the micro-annoyances from my day, saving me maybe 15 minutes daily. But over a year? That's 90 hours of my life back.
