Free online bioinformatics tools

Six free tools that speed up everyday genomics work, from checking a sequence to reviewing a VCF. No accounts, no installs, and no uploads: everything runs privately in your browser.

SeqBench

Sequence stats, reverse complement, six-frame translation, ORFs, and motif search.

CutBench

Restriction site maps, fragment sizes, and a virtual agarose gel.

Open CutBench

AlignBench

Global and local DNA alignment with affine gap penalties.

Open AlignBench

CodonBench

Codon optimization for E. coli, yeast, or human expression.

Why our tools run in your browser

Private by design

Sequences and variant files stay on your device. Nothing is uploaded to our servers or stored.

Instant and installable

No queues or file transfers. Install any tool on your phone or computer with one tap, and it keeps working offline.

Transparent methods

Each tool names its algorithms and parameters, such as nearest-neighbor Tm or Gotoh alignment, so results are easy to cite and check.
