Which Tm calculator is the best alternative to NEB?

OligoPool.com uses the identical SantaLucia 1998 nearest-neighbor algorithm with Owczarzy 2008 salt correction as the NEB Tm Calculator. Independent validation across 50 representative primer sequences shows <0.3°C average deviation. Key advantages over NEB: batch processing (10,000+ primers), client-side computation (sequences never leave your browser), and integrated secondary structure prediction.
