Protein structure prediction

Predict a protein’s 3D structure from its sequence.

Boltfold is a self-serve service that turns an amino-acid sequence into a predicted three-dimensional structure. Paste a sequence, pay per fold, and get back a downloadable PDB file and an interactive 3D view — no account, no setup, no GPU of your own.

How it works

  1. 1

    Paste a sequence

    Enter a protein sequence in amino-acid letters (FASTA accepted), from 16 to 1,000 residues. We validate it before you’re ever charged.

  2. 2

    Pay per fold

    A single fold is a single $2.99 charge via Stripe Checkout. No subscription, no minimum — you pay only for folds you run.

  3. 3

    Receive your structure

    We run the prediction on a GPU and hand back a downloadable PDB plus an interactive 3D view at a private, shareable link. Results take seconds.

Pricing

Simple, usage-based pricing: $2.99 per fold. There’s no subscription and no commitment — each prediction is a one-time charge, billed securely through Stripe.
