Hey Jahid1999! Thanks for your submission! 🚀

To keep awesome-devtools instantly accessible for everyone, all tools must be:

• Browser-based — no downloads or native app installs
• Direct link — goes straight to the tool (not a multi-tool landing page)
• 100% free — no signups, trials, paywalls, or usage limits

Please make sure your PR meets these criteria. It may take some time for your submission to be reviewed — you can occasionally comment with a "bump" to bring more attention to it.

Thanks for contributing! 🙌

Great addition to the developer ecosystem. A centralized browser-based toolkit like this improves productivity by reducing context switching and eliminating the need for multiple standalone utilities. The client-side execution approach is also a strong advantage for privacy and performance. Features like JSON formatting, regex testing, Base64 encoding, and hash generation are tools developers use daily, so having them accessible in one lightweight platform adds real value
