Cradle
Cradle is an AI-powered Science tool — AI protein design platform. Best for: Science. Pricing: Paid (GateOnAI Score: 46/100).
AI protein design platform
Creates custom protein sequences using generative AI trained on structural databases, allowing researchers to specify functional motifs, stability constraints, and expression systems. The platform ingests user‑defined objectives and returns candidate amino‑acid chains with predicted folding confidence scores. Integrated molecular dynamics simulations evaluate thermodynamic stability, while a built‑in solubility predictor flags aggregation risks early in the design cycle. Key capabilities include a drag‑and‑drop interface for defining binding pockets, an automated mutagenesis engine that suggests point mutations to improve affinity, and a library of pre‑trained models for enzymes, antibodies, and nanobodies. Users can run batch jobs that generate thousands of variants in parallel, then filter results by predicted pI, hydrophobicity, or glycosylation sites. The system exports designs in standard PDB and FASTA formats, and connects directly to cloud‑based synthesis services via API. A version‑control system tracks changes to each design, enabling reproducible research and collaborative review. Primary users are protein engineers, biotech startups, and academic labs focused on therapeutic or industrial enzyme development. Cradle replaces manual homology modeling and trial‑and‑error mutagenesis, cutting iteration time from weeks to days. The subscription model offers tiered access to compute credits, with a base plan covering 10,000 design evaluations per month and higher tiers unlocking unlimited runs and priority support. Compared with open‑source tools like Rosetta, Cradle provides a hosted, continuously updated AI backend, reducing infrastructure overhead. A free trial grants limited design attempts, after which users must select a paid plan to continue for ongoing projects.
