About CodeMash
We build free, fast, and private developer tools that help you work smarter. No sign-ups, no tracking, no data storage.
Privacy First
Most tools run entirely in your browser. Your data never touches our servers. For server-side tools, data is processed and immediately discarded.
Performance
Client-side processing means instant results. No waiting for server responses. Our tools are optimized for speed, even with large inputs.
Accessible
No installation, no sign-up, no paywall for essential features. Works on any device with a modern browser.
Developer-First
Built by developers who use these tools daily. Keyboard shortcuts, clean UI, and thoughtful UX for maximum productivity.
Our Story
CodeMash started as a simple collection of data conversion tools built to solve everyday developer problems. What began as an internal tool quickly grew into a comprehensive suite used by thousands of developers worldwide.
We believe that essential developer tools should be free, fast, and respect your privacy. That is why we built CodeMash to process everything client-side whenever possible, ensuring your data never leaves your browser.
