Welcome to Salpa
Salpa is a visual workflow platform for computational molecular science. It lets you build, connect, and execute scientific computing pipelines through a drag-and-drop node editor — no scripting required for common workflows.
What can you do with Salpa?
- Build visual workflows — Drag nodes onto a canvas, connect them, and execute entire pipelines with one click
- Run molecular dynamics — Pre-built nodes for GROMACS, PDB2PQR, and other molecular simulation tools
- See your results in 3D — Open a node’s View tab to see the structures, docking poses and trajectories it wrote, beside the workflow that made them
- Salpa Compute — A separate service that runs Boltz-2, Chai-1, DiffDock, Evo2 and ProteinMPNN on hardware we run (four of them on GPUs), as nodes in your workflow. Each account has a free monthly allowance; nothing is sold self-service
- Install nodes from Salpa Hub — Browse and install node packages from the app’s Marketplace to extend your workflows

How it runs
Salpa is a desktop app — install it once and everything you need (Python, isolated environments, background services) starts automatically. You don’t need to install or configure system tooling.
Open workflows
The app is free; its own source is not public. What is open is the workflow layer: the node packages and templates on Salpa Hub , each under the licence stated with it, and the Salpa CLI . Public Salpa builds are on the releases page .
