Frequently Asked Questions
Instant answers to common questions regarding security, performance, and usage.
Is my proprietary source code uploaded to your servers for comparison?
No, absolutely not. Our diff engine is written in native JavaScript and operates 100% within your local browser environment. The text you paste is never transmitted, stored, or cached on our physical infrastructure.
Which programming languages and syntaxes are supported by the diff parser?
Our engine is language-agnostic. It performs a high-fidelity raw text comparison that is absolutely compatible with any text-based format, including JavaScript, Python, C++, HTML, CSS, JSON, and complex Markdown manuscripts.
Can the tool generate standard unified diff patches for Git integration?
Yes. Using the 'Generate Patch' feature, the tool outputs a standard .patch format which is perfectly suitable for use with `git apply` or other industrial version control systems.
