About
Developer tools that stay out of your way.
BigForgeKit is a growing collection of free browser-based utilities for everyday development tasks.
What is BigForgeKit?
BigForgeKit brings formatting, conversion, inspection, generation and validation tools together in one place. It is built for developers who need to solve small technical problems quickly without installing another application.
The catalogue includes tools for JSON, YAML, XML, SQL, regular expressions, JWTs, hashes, URLs, timestamps, colors, HTTP references and more.
Our principles
Privacy-first
Tool inputs are designed to be processed locally inside your browser.
No signup
Open a tool and start using it without creating an account.
Developer-focused
Clear interfaces, practical defaults and copy-ready results.
Local processing
Most BigForgeKit tools perform their work directly in your browser. Text, source code, credentials and files entered into those tools are not intentionally sent to BigForgeKit application servers for processing.
- No account is required.
- Tool inputs are not intentionally stored.
- Preferences such as theme or favourites may remain in your browser.
- The catalogue is continuously expanded and improved.
