Compare two snippets or whole web experiments. Find the change, see its effect, and get back to building.
Enter code in both panels and click Compare ›
Two independent web projects. Edit or import HTML, CSS and JavaScript, compare each file, then run both sides.
Previews run only when you press Run. JavaScript is optional. Preview network access is blocked; remote libraries, server code, package builds and module imports are not supported. Use local files with relative references.
Download a workspace containing both projects, extract it, and open the folder in VS Code. Your unsaved snippets cannot be transferred automatically to another website.
Desktop launch requires an installed VS Code URL handler and browser approval. Browser VS Code supports local folders in compatible browsers; terminal and server runtimes require other tooling.
A code diff identifies changes between two versions of text. Added and removed lines help locate a regression, review a fix or check configuration changes. This comparator works with JavaScript, CSS, HTML, JSON, SQL, PowerShell and other text formats.
The comparison runs in your browser. Snippets and imported project files are not uploaded or saved automatically. The page loads shared Mightora branding assets from external services. Downloads remain under your control.
Yes. Run two HTML, CSS and JavaScript projects in isolated frames at the same width. Compare the rendered pages visually and inspect each console. This is a manual visual comparison, not an automated pixel difference test.
Spaces, line endings and a missing final newline can produce differences. Line endings are normalised for comparison. The whitespace option ignores leading and trailing spaces on each line, but retains changes within the line.
These files can be compared as text. The preview executes browser HTML, CSS and JavaScript only. Node.js, databases and backend applications need a separate runtime.
No. The tool links to Microsoft’s VS Code for the Web and can launch an installed desktop editor. Code–OSS source is MIT licensed; Microsoft’s VS Code distribution has a separate product licence. See the official licence FAQ and Code–OSS licence.
