Can Line CLI build a whole app or website for me?

Yes. Line can create a new project in an empty folder: it writes files, installs dependencies (with your approval), runs the dev server in the background and checks its work.

Tips for a smooth build#

1. Start in a new empty folder and run line.
2. Ask for a plan first: /plan build a to-do web app with a login page.
3. Approve the plan, then let Line work. Use accept edits mode (Shift+Tab) if you don't want to approve every file.
4. Ask it to run the app and the tests at the end.

What to expect#

• Long files are written in parts so they don't get cut in transit.
• Dev servers and watchers run in background shells; /bashes lists them, and all of them stop when Line exits.
• Big jobs may be split across general sub-agents working on different files in parallel.

Line doesn't host your app on the internet for you. Deploying it is up to you.
