Launch a CLI Tool for Free: Install Routes, Package Managers and the Terminal Clip
Launch a command-line tool by making its install line short and trustworthy, since that line is your landing page. Ship prebuilt release files for each system first, then add the package managers your users already use: a Homebrew tap, a winget manifest, Scoop and the registry of your language. Record a thirty-second terminal clip, post where people run things on their own machines, and avoid install steps that ask for blind trust.
Why is the install line your landing page?
A command-line tool has no screen to be impressed by. What a visitor judges is how fast the first command goes from pasted to working, and whether doing so feels safe. So the install line is the most important sentence on your page, and every extra step before it, a prerequisite, a runtime, a build, is a place where people stop reading.
Work backwards from that. If your audience writes Go or Rust, a single static binary per operating system is a gift. If they write JavaScript, a package on the language registry may be natural. If they are on a Mac, brew install is what they will try first. You do not need every route on day one, but you do need one that works on a clean machine, and you need to have run it there.
Which install routes are worth the work?
| Route | What the docs require | Worth it when |
|---|---|---|
| Release binaries on GitHub | Nothing from anyone; you build per system and attach files | Always, it is the base the others install from |
| Homebrew tap | A Git repository of formulae; the docs say anyone can create one | Day one on macOS, since you control the pace |
| Homebrew core | Open source under a Debian-compatible licence, a stable immutable release and a formula that builds and passes tests on its CI; proprietary binary-only software belongs in a cask | After you have stable releases and some users |
| winget | A pull request to the winget-pkgs repository with a manifest; submissions are validated automatically and may be reviewed by hand | When Windows users ask for it |
| Scoop | A command-line installer for Windows with its own manifests | If your users are Windows power users |
| Language registry, such as crates.io | Cargo’s docs say a publish is generally permanent, with a yank for broken versions | When your users already live in that language |
Two lessons sit in that table. Homebrew core has requirements you can only meet after you have a stable release, so do not plan your launch around getting accepted there; run your own tap and let the core formula be a later milestone. And a registry that makes publishing permanent rewards a dry run: publish a version you would be happy to see for ever, and use the registry’s yank for mistakes.
What should the tool itself get right before you announce?
The Command Line Interface Guidelines at clig.dev, whose authors include two co-creators of Docker Compose, are a good checklist for this. Use them as a review list, not a rulebook. Four things matter most to a new user.
- `--help` that teaches. Lead with an example, not a wall of flags, and make a mistyped command suggest the right one.
- A meaningful exit code and an error that names the fix, so scripts and humans can both react.
- A `--version` flag that prints something you can ask users to paste into a bug report.
- An uninstall path written next to the install path, because a tool that cannot be removed is not tried.
If the tool sends any telemetry, make it opt-in and write down exactly what it sends. Terminal users check, and they tell each other.
What does a four-week plan look like?
- Week 1: cut a real release. Build for each system, attach the files, publish checksums and test the download on machines you did not use to build it.
- Week 2: open the Homebrew tap, and submit the winget manifest as a pull request so the automated validation runs while you work on other things.
- Week 3: record the clip, write the README’s first screen (install, one example, output) and invite five people to try it cold. Fix their snags.
- Week 4: post a Show HN, publish on a board, and answer the threads. Tag each link to find out which one brought the downloads.
The winget submission is placed early because it is validated by a process you do not control. Do not make a Windows announcement depend on a review you have only just started.
What does a good terminal clip contain?
Thirty seconds, one task, real output. Show the install line, then a command that does something a person would want, then the result. Skip the logo animation and the slow typing. A recorded terminal session in the README, ideally as text people can copy next to it, does more than a paragraph about features. The demo video script template can structure the narration if you add a voice.
Pick an example from the situation your audience hates, such as rewriting thirty file names or diffing two config files, and make sure the example is one they could paste and run.
Where do people who live in a terminal gather?
A CLI tool is the textbook case for Show HN, whose guidelines describe things people can run on their computers and ask that the project be easy to try. Read the Show HN playbook before posting. After that, go to the language community that fits the tool, and share a worked example of the problem and not only a link.
To get a permanent public page, launch the tool free on this board: verify one email and publish, with no queue and no paid placement, and the page links to your site normally. Builders who post about command-line work gather under developer tool ideas, and the places for CLI tools list more. If you maintain the code in the open, the open-source launch checklist adds the repository side.
Frequently asked questions
How do I distribute a CLI tool?
Attach prebuilt files for each operating system to a release, then add package-manager routes your users already use: a Homebrew tap, a winget manifest, Scoop and your language’s registry. Start with the release files, since the others install from them, and test each route on a clean machine.
Can I get my tool into Homebrew core right away?
Probably not. Homebrew’s documentation says core formulae must be open source under a compatible licence, have a stable immutable release, and build and pass tests on its CI. Run your own tap first, which anyone can create, and apply for core once you have releases.
How does winget accept new packages?
You open a pull request adding a manifest to the winget-pkgs repository on GitHub. Microsoft’s documentation says an automated process validates the manifest and evaluates it for safety, and that manifests may also be reviewed manually. Submit early, so it does not delay your announcement.
Is a curl-pipe-to-shell install acceptable?
It is common and convenient, but many developers refuse to run it, so offer a plain download with a checksum as well. State which you recommend and what the script does. Trust is cheap to lose in the first minute with a tool people will run on their machines.
