Drug discovery
Predict how a drug binds, from text
Structure and affinity together, from sequence and SMILES alone.
ComposeAI biology as code
Run Boltz, DiffDock, SBML pathways, custom dynamics, and many more lab-contained modules in one pipeline. From your terminal, your browser, or your desktop.

See Biosimulant in action
Four real labs, running in your browser.
Ecology
Predator and prey, in motion
Two simple rules produce a stable cycle, until you push too hard.
Physiology
Stand up. Watch your circulation respond.
Your body's blood-pressure control is a closed loop. Watch it succeed, or fail.
Microbiology
A petri dish, in fast forward
Exponential growth always loses to a finite resource.
The framework
One contract. Any biology standard.
Three steps. Anything else that follows the same contract, an SBML pathway, a CellML cardiac cell, a NeuroML neuron, an ONNX inference module, your own ODEs, can plug straight into your model.
- Subclass
BioModule. - Declare
inputs()andoutputs()as named ports with units. - Implement
advance_window.
The runtime handles unit checks, time alignment, and signal delivery.
import biosimulant
class Pancreas(biosimulant.BioModule):
def inputs(self):
return {"glucose": biosimulant.SignalSpec.scalar(emitted_unit="mmol/L")}
def outputs(self):
return {"insulin": biosimulant.SignalSpec.scalar(emitted_unit="pmol/L")}
def advance_window(self, start, end):
... # advance state to `end`
def get_outputs(self):
return self._outputs
Four ways in
A cadence for every persona
Biosimulant meets you where you are. Code a model from scratch with Studio or the CLI, fork what already exists, or drive it from an agent. Same Hub, same runs, same outputs.
Product family
One platform, three surfaces
An open simulation runtime, a workbench you can run anywhere, and a public hub of runnable labs.
Biosimulant Studio
The simulation workbench, on every surface.
The hosted platform built on the open-source biosimulant runtime. Compose labs, run sims, and compare results from your browser or your terminal today, with the desktop app in beta.
Open Studio

✓ ready · edit inputs, start runs, inspect results
Open source runtime
The MIT-licensed biosimulant runtime.
The Python core that powers the platform. Compose biomodules into runnable worlds, locally, in CI, or anywhere Python runs.
View the runtime
Biosimulant Hub
A public catalog of runnable labs.
Discover, version, and publish labs across SBML, CellML, NeuroML, and more. The shared shelf for simulation work.

Talk to us about your simulation workflow
Biosimulant Studio is for teams building reusable virtual simulations across research and engineering.
- Research teams building reusable virtual experiments instead of one-off simulations.
- Simulation groups that need inspectable workflows, reproducible runs, and shared review loops.
