What is FastLED really good at?

Accepted Answer

We've laid out the answer right above — check the Best Fit section for primary use cases, then scan the tags and categories in the sidebar. Between those three signals, you'll have a solid picture of where FastLED shines (and where it doesn't).

Question 2

What license does FastLED use?

Accepted Answer

The repo is under MIT. That said, licenses occasionally change between versions, so always double-check the LICENSE file in the repository before you commit to anything.

Question 3

How current is this page?

Accepted Answer

The GitHub stats you see here refresh daily through an automated snapshot job. The editorial notes get updated when something meaningful happens — a major release, a license change, or a noticeable shift in the community around FastLED.

Question 4

Can I suggest a project for review?

Accepted Answer

Please do! Scroll down to the Community Notes section and drop a comment with the repo link. We pay close attention to what the community is watching — and strong suggestions often graduate into full editorial reviews.
