CloudLocal
Free, open-source AWS emulator that spins up real databases locally
● The Problem
LocalStack moved core AWS services behind a paywall. Developers need to test Lambda, SQS, S3, and RDS locally without paying $35-50/month per seat. Mocking is unreliable because it does not catch real database behavior or IAM permission issues. MiniStack hit 266 points on Hacker News proving the demand.
● The Solution
Single binary that emulates 30+ AWS services on one port. Spins up real Postgres and Redis containers for RDS and ElastiCache instead of mocking. 2-second startup, 30MB RAM. Drop-in replacement for LocalStack with no API keys, no telemetry, no signup.
