# scalings.xyz > scalings.xyz is an interactive, fully client-side autoscaling simulator. Engineers configure autoscaling parameters, select a traffic pattern, and run a discrete-time simulation to visualize whether their scaling policy handles the load. AI agents can programmatically construct simulation URLs using the URL Hash API. Key facts: - Fully client-side — no backend, no API calls, no auth - Supports Kubernetes HPA, AWS ASG, GCP MIG, and custom/generic autoscalers - URL Hash API: encode a JSON config as base64, link to `scalings.xyz/#config=&autorun=true` — simulation runs on page load - Exports deployment manifests (K8s HPA YAML, AWS CloudFormation, GCP Terraform) and load test scripts (k6, Gatling, Locust, JMeter, Artillery) - Built-in presets: Black Friday Spike, Gradual Daily Ramp, Noisy Neighbor, Step Migration, Bottomless Queue, Death Spiral (OLTP), Death Spiral (Queued) ## Docs - [Full documentation](https://scalings.xyz/docs.md): Complete parameter reference, config schema, traffic patterns, URL Hash API with worked examples, and export types - [Full LLM context](https://scalings.xyz/llms-full.txt): Single-file version with all documentation content inlined ## Optional - [GitHub repository](https://github.com/Agitolyev/scalings): Source code and issue tracker
