SeqBench is a free, browser-based bioinformatics toolkit designed for molecular biologists, bioinformaticians, and students working with DNA, RNA, and protein sequences.
Why I Built It
Most bioinformatics software is either:
- Expensive (SnapGene $200+/year)
- Bloated and slow to open
- Requires installation on every device
I wanted something lightweight, private, and instantly accessible for quick sequence checks in the lab.
Key Features
- 15+ integrated tools: reverse complement, translation, ORF finder, primer Tm, CRISPR gRNA designer, plasmid viewer, codon optimizer, restriction analysis, FASTA/FASTQ stats, pairwise alignment, and more
- Privacy-first: most calculations run locally in your browser — your sequences don't leave your device
- Zero friction: no registration, no installation, no paywalls
- Database integration: fetch sequences from GenBank, RefSeq, and UniProt using just accession numbers
- Educational resources: built-in guides and reference tables for students
Use Cases
- Quick sequence checks without opening heavy desktop software
- Teaching molecular biology and bioinformatics
- Primer design and validation
- CRISPR guide RNA screening
- Learning sequence analysis fundamentals
