# Open Source (/academy/open-source)



Open source is a public workshop.

The tools hang on the wall. Anyone can pick one up, see how it was made, change it, and — if the license says so — take a copy home. You did not invent [Git](/academy/git). You did not invent half the [builder](/builder) stack. Those pieces were already on the wall.

Closed software is a locked bay. You get the machine. You never see the bench.

**You are already standing in the shop**

Almost every [dependency](/academy/dependency) `npx create-hackhaton-space-stack@latest` installs is someone else's tool, published on [GitHub](/academy/github), with a [markdown](/academy/markdown) README. That is why the app is assembled, not carved from bedrock.

People leave tools out for three selfish reasons: trust (you can inspect the steel), speed (a crowd files the burrs), and reach (a good tool becomes the default). It is not charity. It is how the shop stays full.

This product is on that wall too. The [CLI](/academy/cli), the plugin, the [MCP](/academy/mcp) server — readable, forkable, yours to run.

**Hand the file back**

It is not "free as in no work." Maintainers get tired. If a library feeds your demo, file a kind issue or a [pull request](/academy/pull-request). [Fork](/academy/fork) when you need your own bay. Or pin the version and say thank you.

The license is the sign on the door. Read it before you sell the thing you built with their saw.

**What this unlocks**

A weekend that starts on other people's decades.

The wall is stocked. Take a tool. If you sharpen it, hang it back.
