The Developer’s Offline Toolkit, Online.
Toolshref is a privacy-first utility suite designed for Software Engineers, DevOps Professionals, and Backend Architects.
Why Toolshref Exists
Most online developer tools are broken. They are either riddled with pop-up ads, load slowly due to heavy frameworks, or worst of all—they process your data on a remote server.
As developers, we often deal with sensitive data: PII in JSON logs, internal API keys in curl commands, or proprietary logic in Java snippets. Pasting this data into a random “Free Online Formatter” is a massive security risk.
Toolshref was built to solve the “Data Sovereignty” problem. We believe that a JSON formatter shouldn’t need a backend database. We built this platform with a strict “Client-Side Only” architecture. Whether you are formatting 5MB of JSON or analyzing a Spring Boot class, the computation happens 100% in your browser’s JavaScript engine.
Your data never leaves your machine. We use WebAssembly and JavaScript to process inputs locally, ensuring zero data leakage.
No server round-trips. Our tools load instantly and work even if your internet connection drops while you are debugging.
Built for accuracy. Our Java parsers adhere to strict styling guidelines, and our SQL converters follow standard ANSI syntax.
Meet the Architect
Sam • Founder & Lead EngineerSam is a Senior Software Engineer with over 10 years of experience architecting distributed cloud systems. Having worked in Fintech and Enterprise SaaS, he understands the critical importance of data privacy and developer ergonomics.
He created Toolshref out of personal necessity. He needed a suite of tools that could handle complex tasks—like visualizing NPM dependency trees or generating JPA Entities—without the bloat or security risks of existing ad-heavy sites.
“I didn’t build this site for traffic. I built it because I needed a JSON formatter that I could trust with my company’s log files. If it’s on this site, it’s because I use it in my own daily workflow.”
Our Engineering Philosophy
We treat these “simple” tools with the same rigor as production software.
Every tool on Toolshref includes error handling, validation, and strict typing. We don’t just “format” your code; we validate it. If your JSON is invalid, we tell you exactly which line number failed. If your Cron expression is ambiguous, we warn you. We build tools that help you fix bugs, not create new ones.
Feature Requests & Bugs
We are actively maintaining this suite. If you need a specific converter (e.g., YAML to TOML) or spot a parsing error, open a ticket via email.
