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.

Getsitecontrol is an email marketing platform for online stores. It provides merchants with the tools they need to promote special offers, collect emails, manage contacts, and build email marketing workflows.
Getsitecontrol has an official Shopify app and a WordPress plugin. However, it works on any other website platform including Squarespace, Bigcommerce, Magento, and others.

GetsitecontrolDevToolKit.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.
Getsitecontrol's answer:
Ecommerce brands, Shopify merchants, small & medium businesses and creators selling their products and services online.
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.
Getsitecontrol's answer:
Getsitecontrol offers a rare mix of versatility, affordability, and ease of use, combining email marketing and lead generation in one intuitive, beginner-friendly app. Unlike many competitors that charge more for complex features small teams rarely use, Getsitecontrol keeps pricing transparent and accessible, making it ideal for online merchants who want powerful tools that are simple to set up and wonโt break the budget. On top of that, Getsitecontrol offers 24/7 live chat support.
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.
Getsitecontrol's answer:
Getsitecontrol combines email marketing and on-site tools, such as popups, forms, and surveys, in one app, making it easy for ecommerce brands to grow their audience and drive sales without juggling multiple platforms. It stands out for its intuitive interface, AI-powered email templates, dynamic product feeds, and real-time deliverability tracking โ features designed to help lean teams launch polished, high-performing email campaigns quickly and affordably.
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.
Based on our record, Getsitecontrol seems to be more popular. It has been mentiond 2 times since March 2021. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
Any getsitecontrol.com alternatives that can be recommended. Granted it is very easy to use and we use it simply to put up banners and some limited marketing stuff. But $45/month($1740/year) for 5 sites is limiting. That can't be the norm. Source: about 3 years ago
GetSiteControl - my favorite email opt-in tool. Itโs more customizable, and they have their own app for creating the optin forms (there is a WP plugin for integration). Source: almost 4 years ago
