Why builders keep it installedProgram Projects benefits

Works out of the box

Open source installs are one command from the README, and the community threads cover the edge cases before you hit them.

Shared by thousands of builders

This many stars means the defaults are battle-tested across real projects - you inherit other people's hard-won setup knowledge.

Transparent and inspectable

Read exactly what the code, prompts and configs do before you install. Nothing is hidden behind a hosted model.

Actively maintained

The snapshot tracks commits, issues and releases, so you can see the project is alive before you depend on it.
