Catalyst Cloud
Neuromorphic compute
as a service.
Run spiking neural network simulations via API. No hardware, no SDK install, no setup. Just send JSON, get spikes.
# 1. Sign up
curl -X POST https://api.catalyst-neuromorphic.com/v1/signup \
-d '{"email": "[email protected]", "tier": "free"}'
# 2. Define a network
curl -X POST https://api.catalyst-neuromorphic.com/v1/networks \
-H "X-API-Key: cn_live_..." \
-d '{
"populations": [
{"label": "input", "size": 100, "params": {"threshold": 1000}},
{"label": "hidden", "size": 50}
],
"connections": [
{"source": "input", "target": "hidden", "weight": 500}

Define
Describe your spiking neural network as JSON. Populations, connections, neuron parameters. No boilerplate.
Simulate
Submit a job with stimuli and timesteps. Our neuromorphic simulator runs it server-side with hardware-accurate dynamics.
Analyse
Get firing rates, spike count timeseries, and full spike trains. Population-indexed for direct integration with your analysis pipeline.
Built for researchers
Hardware-accurate LIF neurons
Full Loihi 2 parity. Leak-integrate-fire with dendritic compartments, graded spikes, STDP, and 3-factor reward learning.
5 connection topologies
All-to-all, one-to-one, random sparse, fixed fan-in, fixed fan-out. Configurable weights, delays, and compartment targeting.
Sub-second latency
1,000 neurons for 1,000 timesteps in under a second. No queue wait for free tier.
JSON in, JSON out
No SDK to install. No dependencies. Works from any language: Python, JavaScript, MATLAB, Julia, or plain curl.
Population-indexed results
Spike trains grouped by your population labels. Firing rates per population. Direct integration with your analysis code.
