crunr — Run It, Ghost It

crunr is a free, open-source CLI tool that lets you run scripts on powerful AWS GPUs with zero infrastructure overhead. Simply type one command and crunr automatically provisions the exact instance you need, executes your job, and terminates the machine when done — so you only pay for the seconds your script actually runs.

Product Highlights

• Zero Idle Costs: Instances auto-terminate when your job finishes — no more forgotten VMs running up bills
• Your AWS, Your Control: Runs entirely in your AWS account using your credentials; no crunr servers or middlemen
• Universal Script Support: Python, Node.js, Bash, R, Go — run any script without cloud-specific rewrites
• Spot Instance Optimization: Automatically selects the cheapest matching spot instances to minimize compute costs
• Military-Grade Security: AWS credentials never leave your machine; open-source codebase for full transparency

Use Cases

• ML/AI Model Training: Train and fine-tune models on A100s, G5s, or any GPU you need without managing infrastructure
• Data Science Pipelines: Execute heavy ETL, batch processing, and large-scale data analysis on demand
• Startup Compute Workloads: Ship compute-intensive features without hiring DevOps engineers
• Academic Research: Run experiments on proper hardware and pay only for actual compute minutes
• GPU Rental Alternative: Escape the idle billing trap of Lambda Labs, RunPod, and CoreWeave

Target Audience

ML engineers, data scientists, startup developers, researchers, and anyone running compute-heavy scripts who wants AWS GPU power without the operational complexity or surprise bills.
