Flowise FAQ

Is Flowise free?: Flowise 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 Flowise?: No install needed — it runs in the browser.
Does Flowise work on a phone?: No. It needs a computer.
Can I use Flowise commercially?: The licence is Apache-2.0, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
Is Flowise still maintained?: No. The project is archived on GitHub, so there will be no further features or bug fixes. It may work today, but nothing will be repaired when it breaks.
