Execute untrusted code securely across multiple languages.
Yes, even that sketchy Python script from Stack Overflow.
Neuron is a production-ready API that lets you execute untrusted code securely. Built for developers who need reliable, fast, and safe code execution without managing infrastructure.
Execute code in under 500ms with our optimized Go runtime and Redis-backed queue system.
Docker-isolated sandboxes with strict resource limits ensure safe execution of untrusted code.
Support for Python, JavaScript, Java, and C++ with more languages coming soon.
Simple REST API with comprehensive documentation. Get started in under 5 minutes.
Focus on your product, not infrastructure. Neuron handles the complexity of secure code execution.

Ready to simplify your workflow?
Try it nowSimple API, powerful results. Execute code securely in three easy steps.
Make a POST request with your code and language
fetch('/v1/runner/submit', {
body: JSON.stringify({
language: 'python',
code: 'print("Hello")'
})
})Code runs in isolated Docker sandbox with resource limits
Receive output, errors, and execution metadata
{
"output": "Hello",
"status": "success",
"executionTime": "145ms"
}That's it. No complex setup, no infrastructure to manage.

Everything you need to know about Neuron
Every execution runs in an isolated Docker container with strict resource limits, network restrictions, and automatic cleanup. Your code never touches our host system. We treat it like it's trying to hack the Pentagon (even if it's just printing 'Hello World').
Currently Python, JavaScript, Java, and C++. We're actively working on adding more languages. Go and Rust are on the roadmap, but they're being stubborn about it.
We tested it extensively: ~500ms under normal conditions, but can spike to 1200ms when everyone decides to run their code at the same time. Think of it like a coffee shop - fast when empty, slower during rush hour ☕
Yes! Get 100 free credits on signup (bonus 200 for early users!). We only charge for successful executions - compilation errors, timeouts, and memory errors are on us.
Absolutely! We're using it in production... to test itself. Meta, right? 🤯 But seriously, we are trying to make it production-ready.
Sign up for free, get your API key, and make your first request. Full integration takes less than 5 minutes. If it takes longer, you might be overthinking it (or our docs need work - let us know!).
