SwapSeq

Detects swapped tubes, mislabelled samples and sample-sheet shifts in longitudinal microbiome studies (16S and shotgun) from each subject's microbial fingerprint. It self-calibrates by planting errors in the user's own labels, reports its own detection power, and runs entirely in the web browser with no data uploaded. An R package (swapseqr) runs the same engine on phyloseq objects or count matrices.
