The Problem: “Quick” Tools Are Often Dangerous 🛑
We’ve all been there. You need to format a messy JSON response, debug a JWT token, or convert a quick SQL schema. You Google “online json formatter,” click the first link, and paste your data.
But wait. Did you just paste production database credentials into a random server? Did you just send your API key to a third-party logger?
I was tired of wondering where my data went. So I spent the last few months building the ultimate alternative.
Meet UtilityForge 🛠️
UtilityForge is a suite of 250+ developer tools that run entirely in your browser.
Crucial Architecture Choice: I built this using a “Client-Side First” philosophy. When you use our PDF converters, Image tools, or Code formatters, the data involves zero server processing. It stays in your browser’s memory.
🚀 The “Killer” Features (The Developer Studio)
I didn’t just want simple converters. I wanted a full IDE experience without the setup.
- 🗄️ Database Schema Designer (Visual ERD)
Forget heavy desktop apps. I built a full drag-and-drop database designer.
Visual: Drag tables, connect foreign keys visually.
Templates: One-click setups for SaaS, E-commerce, and Blogs.
Export: Instantly grab the CREATE TABLE SQL, Prisma Schema, or TypeScript interfaces.
Private: Your schema design never leaves localStorage.
- ⚡ REST API Client (Postman Alternative)
Why open a heavy desktop app just to test one GET request?
Full Power: GET, POST, PUT, DELETE with custom headers and body.
History: Auto-saves your request history (locally!).
Localhost Safe: I built a smart proxy that allows you to test public APIs secure, but actively blocks SSRF attacks to local networks.
- 💻 Coding Ground
A VS-Code style environment in your browser.
Multi-language: Python, JavaScript, HTML/CSS, C++, and 50+ more.
Instant Result: Compiles and runs directly in the browser tab.
🛡️ Security & Privacy by Design
Because this tool is built for developers, I knew security had to be top-notch.
CSP: Strict Content Security Policy to prevent XSS.
No Analytics Abuse: We don’t track your input data. Ever.
Open Architecture: It’s built on Next.js, and the “Engine” pattern means we can add new tools in minutes.

Try It Out!
I’d love your feedback. Does the Database Designer feel intuitive? Is the REST Client missing a header you use often?
