Microbial growth screens generate thousands of curves, but cross-experiment comparison and mapping growth phenotypes to genotypes or environments routinely require custom code. GUIbiont is a no-code browser application for quality control, curve fitting, clustering and metadata-linked analysis with machine learning techniques. Interactive sessions export as Julia scripts, allowing users to reproduce or extend browser analyses. Validated across 3,885 E. coli deletion strains and 13,608 defined-media curves, GUIbiont recovered known auxotrophic and nutrient-dependent phenotypes.
