Which should you use? A side-by-side look at what each one does, who it suits, what it costs, how hard it is to set up, and where each falls short.
Open source · MIT
A syntax-highlighting pager that makes git, diff, and grep output easier to read.
Open source · MIT
A diff tool that compares files by their syntax instead of by line.
The short answer
Choose delta if you need…
- Developers who read a lot of git diffs or git show output in the terminal
- People who want syntax-highlighted git blame output
- Developers who use rg or git grep and want colored matches
- Users who want bat's color themes applied to their diffs
Choose difftastic if you need…
- Developers reviewing code changes in git where reformatting adds noise
- People comparing source files in supported programming languages
- Teams who want a check that two files have the same syntax, using --check-only
- Users of editors like Emacs who want syntax-aware diffs in their workflow

What each one is
delta
Delta is a terminal program that sits between git and your screen and recolors diffs, blame output, and grep results with syntax highlighting. It highlights changed words within lines and can show diffs side by side with line numbers. People use it to make reviewing code changes faster and easier to follow.
difftastic
Difftastic is a command-line tool that compares two versions of a file by their code structure rather than line by line. It highlights what actually changed, so reformatting code that splits across lines shows up as no real change. It can also be used with git and other version control systems.
Best for
delta
- Developers who read a lot of git diffs or git show output in the terminal
- People who want syntax-highlighted git blame output
- Developers who use rg or git grep and want colored matches
- Users who want bat's color themes applied to their diffs
difftastic
- Developers reviewing code changes in git where reformatting adds noise
- People comparing source files in supported programming languages
- Teams who want a check that two files have the same syntax, using --check-only
- Users of editors like Emacs who want syntax-aware diffs in their workflow
Strengths
delta
- Uses the same syntax-highlighting themes as bat
- Highlights word-level changes within lines
- Configurable through standard git config settings
difftastic
- Understands syntax, so whitespace-only and reformatting changes are handled sensibly
- Supports over 30 programming languages according to the README
- Works with git and other version control systems, with setup instructions in the manual
Not ideal for
delta
- People who only use a graphical git client or web-based code review, since delta works in the terminal
- Users who want to keep plain git output exactly as it is, since delta changes how diffs look by design
difftastic
- People who need a patch file to apply later, because its output is for human reading only and does not generate patches
- People who need to merge branches, because it does not perform AST merging (the README points to mergiraf for that)
- People diffing very large files with many changes, because the README says it scales poorly and can use a lot of memory
- Users who need diffs of unordered data without sorting first, because it treats order as significant
Trade-offs
delta
- Output styling is extensive, so setting it up well takes some reading of the manual
- Commit hyperlinks are only supported for GitHub, GitLab, SourceHut, and Codeberg, per the README
difftastic
- The README says it can be slow and use a lot of memory on files with many changes
- Falls back to a line-oriented diff when parse errors occur, so results vary by file
- Side-by-side display can be confusing, according to the README
