Free tools for protein engineers
CPU-only web tools for the tasks that sit in front of every binder campaign: surface epitope identification, antibody developability scoring, and yeast display library design.
Run in the browser. No install, no GPU, no credit card for the free tiers. Used by academic labs, seed biotechs, and industrial R&D groups to scope campaigns before committing compute or wet-lab budget.
Epitope Scout
Ranks surface epitope patches on a target protein for binder design campaigns, scored by hydrophilicity, conservation, and pocket geometry.

Aggregated liability score for antibody, nanobody, and de novo binder sequences covering hydrophobic patches, charge distribution, glycosylation motifs, and aggregation-prone regions.

Designs feasibility-ranked NNK or NNS mutation libraries against a parent scaffold, with diversity math, expression-readiness flags, and primer plans.

These tools are the scoping layer we use in our own binder pipelines before committing to RFdiffusion, BindCraft, or a yeast display sort. If you want the full campaign run end to end, with compute, wet-lab validation, and a technical report, the Binder Pilot is the smallest entry point.
