About biodna.online

biodna.online is a lightweight, browser-based DNA barcode generator designed for modern sequencing workflows. It focuses on designing barcode sets that are:

• GC-balanced: within user-defined GC content windows.
• Free of long homopolymers: configurable maximum run length.
• Motif-aware: avoids custom forbidden motifs such as restriction sites.
• Error-tolerant: barcodes are separated by a minimum Hamming distance.

Use it to quickly prototype multiplexed libraries, NGS index sets, and cell barcoding schemes without installing heavy bioinformatics pipelines.
