Molchanica
A visual tool for structural biology and drug-design
Load from PDB, PubChem and other databases. Run MD, view electron density, and edit molecules.
Computer-assisted drug design
Perform virtual screening using pharmacophores. Compute ADME and toxicity of any molecule using machine learning. Align molecules.
Specialized tools for molecular docking, building nucleic acids, and simulating liposomes and lipid nanoparticles (LNPs). Drug-development features including molecule alignment, ADME and toxicity prediction, and pharmacophore-based screening.
Molchanica uses a powerful visualization and camera system that lets you explore molecular systems without friction. Freely navigate your view throughout the system.
ORCA integration for quantum chemistry.
Why molchanica
MD built in
Run molecular dynamics with Amber force fields and OPC water directly in the viewer. No separate pipeline.
Drug development
Molecule screening, alignment, pharmacophores, and ADME.
Density and docking
Render 2Fo-Fc maps, isosurfaces, and visualize docked ligands from crystallography or Cryo-EM data.
Fast and modern
Rust, CUDA, and thread pools for parallelization. Tight integration with RCSB, PubChem, DrugBank, and PDBe.

File formats
Supports the most common formats for interop with other software. This includes mmCIF, SDF, Mol2, PDBQT, XYZ, MAP, MTZ, DCD. Amber dat/lib/frcmod/prmtop, GROMACS top.
GPU and CPU parallization
CUDA on Nvidia GPUs; otherwise multi-core + SIMD CPU operations.
CLI commands
Subset of PyMOL-style commands for fetch/load/show/edit and camera ops.
