Home-grown tools.
54 services across Windows, Linux, and macOS — a real graphical menu or the classic terminal, your call. This carousel is the short version of what makes it more than a checkbox list.
Stream straight into mpv or download in the quality you set once — a menu that remembers, not a wrapper that guesses.
Watch or download anime from the terminal, one keypress apart — the one thing the base tool leaves out.
Plug it into any machine and it behaves like it's installed — without installing anything on the host.
Video/audio conversion, compression, and trimming with ffmpeg — a graphical app or a terminal tool, your choice at install time.
Every port gets a plain-language reason for its label — block or close what you choose, nothing acts on its own.
Set up a machine like you mean it.
onecmd installs and configures 54 tools — dev environment, browsers, media, gaming, electronics, AI — on Windows, Linux, or macOS. Pick what you need from a real graphical menu, or drive the whole thing from the terminal. One command gets you there.
Get onecmd as a regular Windows app.
Same 54-service menu, packaged as a desktop app — download, open, check the boxes you want. No PowerShell required. Install it normally, or grab the portable build and run it straight off a USB drive.
SHA256: 78a816b7…2ee155c6
onecmd.exe straight from there. Nothing gets installed or written to the host PC: no registry, no shortcuts, no files outside that folder. SHA256: 405cad31…fa773f6a
Built like an installer that expects things to go wrong.
Not a wrapper around a wishlist file — onecmd handles the parts that actually break: half-finished downloads, flaky networks, and the moment you want it gone but not what you built with it.
Point-and-click, or not
The GUI opens by default — a local page at 127.0.0.1, never exposed to the network. Prefer arrow keys? onecmd --tui drops you into the classic terminal menu instead.
Never a half-finished install
Every download lands in a temp folder first and only replaces the real thing once it's complete. A dropped connection can't leave onecmd — or what it's installing — half-built.
Retries the flaky stuff
Network steps back off and retry on their own instead of taking down the whole install over one bad packet.
Uninstalls only itself
onecmd --uninstall removes the installer. Git, Docker, yt-dlp — whatever you installed with it stays exactly where you left it.
One catalog, three OSes
Windows, Linux, and macOS read from the same 54-service catalog — and for the media tools, the literal same script runs unmodified on all three.
Real tools underneath
Checking a box runs winget, brew, or apt for you — onecmd doesn't reinvent package management, it just gives it one front door.
Five tools we didn't just install — we built the front end (or the whole thing).
yt-dlp, ani-cli, and ffmpeg are already excellent, open-source, and not ours. What onecmd adds is the layer around them — plus two tools, Media Converter and Port Scanner, that onecmd built outright.
Play it. Don't just download it.
Set a quality once and it's remembered from then on. Stream straight into mpv, or grab the video you're watching without breaking playback — the same script runs unmodified on Windows, Linux, and macOS.
One keypress from watching to keeping.
ani-cli finds and streams anime from the terminal on its own — the menu around it remembers your quality and adds the one thing the base tool skips: a real download option, one keypress from watching.
Claude Code, on a USB stick.
Plug it into any machine, run one launcher, and Claude Code behaves like it's installed — nothing touches the host. A real drive picker, checksum-verified downloads, and a fixed path across machines.
Convert without uploading anything.
ffmpeg does the real work — onecmd wraps it in a menu that needs no flags. Convert, compress, or trim video and audio locally, from a graphical app or a terminal tool, your choice at install time.
See what's listening, and why it matters.
Every port gets a plain-language reason for its label, not just a color. Block by firewall or kill the process — always with an on-screen confirmation — and onecmd only ever undoes blocks it created itself.
54 services, nine shelves.
