Hey DEV community! 👋
If your workflow is anything like mine, your browser is probably a chaotic mess of bookmarks. Since We started building digital experiences back in 2017, We found ourself constantly jumping between a dozen different web apps—a JSON formatter here, a regex tester there, a JWT decoder on some ad-heavy site, and a separate tab for generating Tailwind classes.
It was slowing down our workflow. So, to streamline operations for our agency, NeedleCode, we decided to build our own unified toolkit.
Today, we're opening up the NeedleCode Toolkit to the community. It’s a suite of 90+ high-performance tools for developers, SEO, and productivity—completely free to use, with no paywalls and no bloated sign-ups.
Here are a few highlights of what you'll find inside:
🔒 Security & Privacy
Because you shouldn't have to paste sensitive data into sketchy third-party sites:
- Advanced Password Strength Checker
- Security Header Checker & Security Scanner
- Hash Generator & Encryption Tools
📈 SEO & Performance Optimization
If you're launching client sites or personal projects, these help you verify everything is technically sound:
- SEO Audit Tool & Page Structure Analyzer
- Redirect Chain Checker & Broken Link Checker
- Schema Markup Generator
- Website Speed Test & Mobile Friendliness Test
🎨 Design & Productivity
- SVG Optimizers, Image Compressors, and Format Converters.
- Unix Timestamp Converters, Regex Testers, and Base64 Encoders.

We’d love for you to take it for a spin! Bookmark it for your next project, and let me know in the comments if there are any specific tools, parsers, or generators you'd like to see added to the list. I'm actively expanding it!
Happy coding! 🚀
