About Nafru Developer Tools (DevTools)
Nafru Developer Tools (DevTools) is a comprehensive suite of web utilities designed to accelerate the daily workflows of software developers, system administrators, data analysts, and designers. It allows you to complete routine and time-consuming tasks in seconds while coding, integrating APIs, or formatting data.
With the JSON Formatter and SQL Formatter tools in our package, you can make complex code structures readable, minify them, and validate syntax errors. You can seamlessly convert between data formats using our tools like Base64 Encode/Decode, URL Encoder/Decoder, HTML Entity Converter, Number Base Converter, and Unix Timestamp converter. For your security and testing processes, critical assistants such as random password generator, UUID v4/v7 generator, MD5/SHA-256 hash calculator, regex tester, and cron expression validator are at your disposal.
In addition, you can use our SEO validation tools such as robots.txt, XML sitemap, meta tag, Open Graph, and Schema Markup to increase the search engine visibility of your websites. You can analyze your web infrastructure with network and security tools such as SSL certificate check, DNS record lookup, and redirect chain tracking. All data processing on Nafru DevTools runs entirely locally in your browser; unless server-side validation is required, your code, keys, or private data are never transmitted. Nafru DevTools is your ultimate helper for a developer-friendly, minimalist, and ad-free workspace.
