# LocalStack Service Tiers Reference

This skill provides knowledge about LocalStack service availability across pricing tiers.
KECS uses LocalStack for AWS-compatible services, relying on free tier services for ECS integrations.

## Quick Reference

### Key Insight for KECS Development

**ECS is NOT available in LocalStack Free tier** - it requires Base tier ($39/mo).
This is one of the primary reasons KECS exists: to provide a free, local ECS-compatible environment.

### Pricing Tiers

| Tier | Price | Services |
|------|-------|----------|
| Free (Community) | $0 | 30+ services |
| Base | $39/mo | 55+ services |
| Ultimate | $89/mo | 110+ services |
