I built Flexi because I was tired of rebuilding the same sections for every client project. Other libraries fell short. They were either too slow, too branded, or too much junk in the theme. So I built the one I actually needed. Sections and blocks that connect to metafields from day one, dev mode for full control, and a tiny footprint that passes PageSpeed every time. Three years. Five versions. Flexi is the app I needed all along.
