repomix vs contextzip
repomix packs a repository into one AI-friendly text file. contextzip covers the same ground (repo links, a web tool, MCP, an npm install) but sends the real files as a ZIP, and then does the part repomix leaves to you: writing the AI's changes back into your project.
Feature comparison
| Feature | repomix | contextzip |
|---|---|---|
| Output | One packed text file: XML by default, or Markdown, JSON or plain text with --style, split into parts with --split-output | A ZIP of your real files, with a report and a CONTEXTZIP.md telling the AI how to reply |
| Local, private, uncommitted code | Yes. It packs a local directory. | Yes. It packages the files on your disk, committed or not. |
| Repo link, no clone | --remote with a GitHub URL or user/repo (needs git installed), or repomix.com. Its docs cover public GitHub repos. | Yes: GitHub, GitLab and Bitbucket links, folders and refs, with no git or clone. Private repos with a token or your gh login. |
| Stack-aware exclusions | One general default ignore list (node_modules, .git, build folders), plus .gitignore, .ignore and .repomixignore | Yes. Detects Node.js, Next.js, Python, Django, FastAPI, Rust, Go and Ruby, including several stacks in one monorepo, and applies each one's rules on top of .gitignore. |
| .env and secrets | A Secretlint scan, on by default, leaves out files that look like they hold credentials. Nothing is redacted. | Secret files (.env, private keys, cloud credentials) are left out by default. A .env you include on purpose keeps its keys, with every value replaced by [REDACTED]. |
| Clipboard as a file | --copy copies the packed output as text | Yes. The ZIP is copied as a real file, so you paste it straight into an upload box. |
| Applying AI changes back | No. It packs code for the AI; the way back is up to you. | cz apply-zip puts each file in its real folder (even when the AI flattened the paths), three-way merges around your edits, and asks before anything risky |
| Reply as a pull request | No | cz apply-zip --pr turns the AI's ZIP into a branch and a pull request on GitHub |
| Web UI | repomix.com | Yes, on the home page: drop a folder (packed in your browser, never uploaded) or paste a repo link. In Chrome and Edge it also applies a reply to your folder. |
| Editor extension | No official one. A community extension, Repomix Runner, is on the Marketplace. | Yes: an official VS Code extension that packages and applies replies, with conflicts in the merge editor |
| MCP server | Yes (--mcp) | Yes (cz mcp), with tools to package and to apply a reply |
| Install | npx repomix@latest with nothing installed, or npm, yarn, bun, Homebrew | pip install contextzip (or pipx, uv), or without Python: npm @contextzip/cli, Homebrew, Scoop |
Where contextzip wins: a repomix alternative for edits
- The AI's changes come back into your project.
cz apply-zipputs each returned file in its real folder even when the AI flattened the paths, three-way merges around edits you made since, and asks before anything risky. repomix stops once the text is packed. - A reply to a GitHub repo becomes a pull request.
cz apply-zip --prcommits the AI's ZIP to a new branch and opens the PR, without a clone. - Repo links work on more hosts, without git. contextzip downloads one commit from GitHub, GitLab or Bitbucket over HTTPS, including private repos with a token. repomix's
--remoteclones with git. - The web tool keeps your code on your machine. Drop a folder on the home page and it's packed in the browser, with the same rules as the CLI. In Chrome and Edge the same page applies the AI's reply to that folder.
- It pastes into an upload box. The ZIP goes on your clipboard as a file, so Ctrl+V in Claude or ChatGPT attaches it with folders intact, instead of filling the message box with text.
- Exclusions follow your stack. contextzip detects Next.js, Django, Rust and the rest, per folder in a monorepo, and leaves out what that stack doesn't need, with no ignore file to write.
- A
.envcan be shown safely. Include it and the keys stay while every value is redacted, so the AI sees which settings exist without the secrets. - An official editor extension. The VS Code extension packages, notices the reply in your Downloads, and opens conflicts in the merge editor.
If you only want to read a repo, either one works. If you want the AI's edits back in your code, that's what contextzip is built for.
