GitHub Action — run on your pull requests

Two lines, and it runs entirely inside your own runner — your source never leaves GitHub. Fully unlocked — the free licence is built into the Action, nothing to install. (Public repos: code-delta-app/action · releases.)

# .github/workflows/codedelta.yml
- uses: actions/checkout@v4
  with: { fetch-depth: 0 }
- uses: code-delta-app/action@v1

1. Add the workflow file

   Create .github/workflows/codedelta.yml in your repo with the snippet above — the free licence is built into the Action, nothing to add.

2. Open a pull request

   Within a minute you get a CodeDelta comment on the PR — churn + AI findings — plus the Security tab and the merge gate. Full details on the CLI / CI page.

To keep using it past 31 October 2026 — or to bring your own licence sooner — add a CODEDELTA_LICENSE secret (request one below); it overrides the built-in licence automatically.

Not on GitHub? The same engine runs anywhere Docker runs — GitLab, Jenkins, or a laptop: see Docker below.

Desktop app — Windows

The Windows desktop build (x64, Windows 10/11) is available as a direct download. It ships as a password-protected zip — password code-delta — so it downloads cleanly through the corporate gateways and mail filters that block plain installers.

Password-protected zip (opens with Windows' built-in extractor) — password code-delta. The installer is unsigned, so Windows may show an "unknown publisher" warning: click More info → Run anyway. Needs the free licence file to run — download it here (valid to 31 October 2026), or request your own.

Desktop app — macOS

The macOS desktop build (Apple silicon) is available as a direct download — signed and notarized by Apple, so it opens without security warnings.

Open the .dmg, drag CodeDelta to Applications, and launch it — no security warnings (Apple-notarized). Needs the free licence file to run — download it here (valid to 31 October 2026), or request your own.

Desktop app — Linux

The Linux desktop build (x86-64) is available as a single-file AppImage — download one file, make it executable, run. Prefer a terminal? A .tar.gz bundle (engine + GUI) is offered on the thank-you page.

chmod +x CodeDelta-x86_64.AppImage then run it. Needs the free licence file to run — download it here into ~/.codedelta/ (valid to 31 October 2026), or request your own.

Docker — for locked-down CI

For environments that won't allow local installs but do allow pulling approved images — most hardened corporate CI. The image is public on GitHub Container Registry; the same engine runs identically on GitLab, Jenkins, a self-hosted box or a laptop.

# pull once, run anywhere — nothing installed on the host
docker run --rm -v "$PWD:/work" -e CODEDELTA_LICENSE_B64 \
  ghcr.io/code-delta-app/codedelta scan /work/new /work/old

Needs the free licence file to run — download it here (valid to 31 October 2026), then pass it in: export CODEDELTA_LICENSE_B64=$(base64 -w0 codedelta.lic). Full recipes on the CLI / CI page.

CLOC — free cross-check utility

CLOC is a free, GPL-licensed, command-line code-counting tool that also offers churn for SLOC (CodeDelta has an equivalent, superior, headless engine). We found CLOC useful for cross-checking CodeDelta’s results — on identical file sets the two agree on physical lines to the exact line. It doesn’t offer language-specific logical statement diffs (changed_LLOC), data element detection, an SQL database, embedded AI agent detection and all the other good stuff that makes CodeDelta unique, but it’s a great way to validate the size of codebases and verify CodeDelta output! It supports 395 languages — where “support” means it knows each language’s comment syntax and file extensions. That list should help you decide which languages you’d like incorporated into CodeDelta: incorporation means we strip comments via language-specific syntax and detect logical statements and data elements using the same dedicated language specification.

v2.10 — a password-protected zip (password code-delta, same as our Windows download — passes corporate gateways) holding the single Perl script (its own source) and the licence text.

Third-party software by Al Danial and contributors, redistributed unmodified under the GPL-2.0 licence (full text) — not a CodeDelta product and no endorsement implied; copyright notices are preserved in the script itself, which is its own source.
