Ziplark by doaipm ↗

Free & open source · MIT

Every archive.
One small app.

Ziplark extracts ZIP, RAR, 7z, tar and ISO, and creates ZIP (AES-256), 7z and tar — from a 1.4 MB binary. One Rust engine, three ways to drive it: a desktop app, a command-line tool, and an MCP server.

Why Ziplark

🪶

Small & fast

Size-optimized release build — LTO, stripped, panic=abort. The desktop app uses the OS webview, so there's no bundled Chromium.

🛡️

Safe by design

Every extraction path funnels through a single zip-slip guard. No entry can ever escape the destination folder — not from a crafted ZIP, RAR or tar.

⚙️

One engine, three ways

The GUI, CLI and MCP server are thin shells over one Rust core. Whatever the app does, the CLI does identically — and scripts can too.

📦

Every common format

ZIP, RAR (incl. RAR5 & encrypted), 7z, tar and the compressed-tar variants, single-stream gz/bz2/xz/zst/lz4 — and ISO 9660 disc images.

Format support

RAR creation is intentionally unsupported — the RAR compression format is proprietary. Extraction (including RAR5 and encrypted archives) works fully.

Built for terminals and agents too

CLI — ziplark

List, extract, create and verify any archive. --json on every command for scripting.

ziplark list  movie.rar
ziplark extract photos.zip -o ./out
ziplark create backup.tar.zst ./src --level best
ziplark create secret.zip ./private --password hunter2
ziplark test  download.7z

MCP server — ziplark-mcp

Drive Ziplark from any LLM over the Model Context Protocol. Read tools are always on; writes are gated behind --allow-write.

FAQ

Is Ziplark free?

Yes — free and open source under MIT, with no ads and no telemetry.

Can Ziplark open RAR files?

Yes. Ziplark extracts RAR and RAR5 archives, including password-protected ones. It doesn't create RAR archives — that format is proprietary — but it reads them fully.

Does it work on macOS, Windows and Linux?

All three. macOS ships as a universal, notarized build; Windows as an .msi/.exe; Linux as .deb and AppImage.

Is it a good free alternative to WinRAR, 7-Zip or The Unarchiver?

Yes. Ziplark is cross-platform, free and tiny. It reads ZIP, RAR, 7z and tar and creates ZIP (AES-256), 7z and tar — plus it ships a CLI and an MCP server for scripting and automation. Guides: free WinRAR alternative, open RAR on Mac, and 7-Zip for Mac.

Does it support encrypted / password-protected archives?

Yes. It creates AES-256 encrypted ZIP and 7z archives, and reads encrypted RAR and 7z archives.

Can I use it from the command line or scripts?

Yes — the ziplark CLI does everything the app does, with --json on every command, and ziplark-mcp exposes it to any LLM over the Model Context Protocol.
