Auto-scaling code execution engine running inside secure, isolated Docker sandboxes.
Tech Stack
Next.jsExpress.jsTypeScriptDockerBullMQRedisMongoDBClerk
Key Highlights
- Isolates runtime environments via CPU-capped, memory-limited, net-disabled Docker sandboxes
- Distributes high-throughput jobs asynchronously using BullMQ and Upstash Redis queues
- Features real-time output capture with automatic TTL cleanups and truncation controls
Overview
CloudExecX is a secure, multi-tenant code execution engine designed to run untrusted user code safely at scale. The platform uses Docker containers managed dynamically via Dockerode to isolate execution environments, enforcing strict resource bounds (128MB RAM, 50% CPU caps, and no network access).
Built on a microservices topology, the Next.js frontend sends execution jobs to an Express API, which queues tasks using BullMQ and Upstash Redis. Scale-out workers process the queue, spinning sandboxes up and down on-demand. Output is captured, truncated if excessive, and returned via real-time streams.
