What Is CodeDelta?
CodeDelta is a browser-based diff tool that compares text, code, JSON, and XML with character-level precision across 36 programming languages. It runs entirely in your browser — your files are never uploaded to a server.
The diff engine highlights changes at the character level, not just per line. If a single variable name changes inside a long statement, CodeDelta marks that specific word instead of flagging the entire line. Results appear in side-by-side or unified inline view, and you can export them as PNG, PDF, or SVG for code reviews, documentation, or presentations.
Common use cases include comparing pull request changes offline, auditing config file edits (YAML, TOML, INI, JSON), checking document revisions, and verifying API response differences. The tool works with any plain text — from a two-line snippet to files with thousands of lines.
Core diffing is free with no account required. Pro (syntax highlighting and export) costs $3/month, and you can cancel anytime.
