DevToolKit is a collection of 19 free online developer tools that run entirely in the browser. No backend, no signup, no data ever leaves your machine. Built with Next.js 14 and Tailwind CSS. Tools include: JSON Formatter & Validator, JSON Tree Viewer with node path copying, YAML-JSON Converter, SQL Formatter, Base64 Encoder/Decoder (text + file drag & drop), URL Encoder, JWT Decoder, Hash Generator (SHA-1/256/384/512 via Web Crypto API), Password Generator, Cron Expression Parser with next run time calculation, PostgreSQL Config Generator (free PGTune alternative), UUID v4 Generator, QR Code Generator (PNG + SVG), Lorem Ipsum Generator, Regex Tester, Text Diff Checker, Unix Timestamp Converter, Color Converter (HEX/RGB/HSL), and HTTP Status Codes Reference. Every tool processes data locally using native browser APIs. No server-side processing, no cookies, no analytics tracking of input data.

DevToolKit.site's answer:
DevToolKit runs 100% in the browser with zero signup. Unlike CyberChef, which has a steep learning curve with its recipe-based interface, DevToolKit gives you 19 standalone tools โ each with a clean, focused UI for a single task. Unlike DevToys, it works on any device with a browser โ no desktop app installation needed. And unlike SmallDevTools or similar online toolkits, DevToolKit includes unique tools like a PostgreSQL Config Generator (a free PGTune alternative), a Cron Expression Parser that calculates next 10 actual run times, and a JSON Tree Viewer with click-to-copy node paths. Every tool uses native browser APIs like Web Crypto for hashing โ no data is ever sent to a server, which matters if you're working with production JWTs, API keys, or database configs.
DevToolKit.site's answer:
Backend and full-stack developers who deal with JSON, JWTs, SQL, cron jobs, and PostgreSQL configuration on a daily basis. DevOps engineers who need quick encoding, hashing, or regex testing without installing CLI tools. Developers who care about data privacy and don't want to paste production tokens or API responses into random websites that may log input data.
DevToolKit.site's answer:
I'm a backend developer with 10+ years of experience in Python and Go, working on distributed systems and microservices. Every day I was jumping between 5-6 different sites to format JSON, decode a JWT, test a regex, or convert a timestamp โ each one bloated with ads, cookie banners, and signup walls. One evening I decided to build all the tools I actually use into a single place where everything runs client-side. The first version had 15 tools and took a weekend to build with Next.js and Tailwind CSS. After getting feedback, I added a PostgreSQL Config Generator (because PGTune hasn't been updated in years), a JSON Tree Viewer, and an HTTP Status Code Reference. It's now at 19 tools and growing based on what developers ask for.
DevToolKit.site's answer:
Next.js 14 with App Router for server-side rendering and per-page SEO metadata. Tailwind CSS for styling with a custom dark theme. Web Crypto API (crypto.subtle) for SHA-1/256/384/512 hashing and cryptographically secure password generation โ zero external crypto libraries. FileReader API for client-side Base64 file encoding. All tools are React components with no backend โ the entire app is static and deployed on Vercel. Each tool is a separate route with its own metadata, canonical URL, and sitemap entry for independent Google indexing.
DevToolKit.site's answer:
DevToolKit is a free tool with no accounts, so we don't track individual users. It's used by individual developers and small teams who need quick, private access to common dev utilities without enterprise overhead. The tool is designed for anyone who works with APIs, databases, or web development and wants a fast, ad-free, privacy-respecting alternative to existing online tools.
DevToolKit.site's answer:
Three things set DevToolKit apart. First, it includes tools you won't find in other online toolkits โ a PostgreSQL Config Generator that replaces PGTune with hardware-aware tuning calculations, a Cron Expression Parser that doesn't just describe the schedule but calculates the next 10 actual execution timestamps, and a JSON Tree Viewer where you click any node to copy its full JavaScript path like data.users[0].email. Second, every tool uses native browser APIs instead of external libraries โ hashing runs through Web Crypto API with hardware acceleration, passwords use crypto.getRandomValues(), file encoding uses FileReader โ meaning zero dependencies and zero data transmission. Third, each of the 19 tools lives on its own URL with dedicated SEO metadata, so you can bookmark devtoolkit.site/jwt-decoder/ and go straight to it โ no navigating through menus or loading tools you don't need.
this tool is powerful for article writing with sources already mentioned. just give him a topic/company name it will research for you everything about it. Really reliable tool.
I just love it
