plandex FAQ
- Is plandex free?
- plandex itself is free, but it needs an API key for an external AI service. That service charges separately, though some have a free tier.
- Do I need to install anything or write code to use plandex?
- It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.
- Does plandex work on a phone?
- No. It needs a computer.
- Can I use plandex commercially?
- The licence is MIT, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
