LocalStack CE Alternatives

LocalStack Community Edition — the open-source AWS cloud emulator that let developers run S3, Lambda, DynamoDB, SQS, and 30+ other AWS services locally — shuts down on March 23, 2026. The unified Docker image now requires registration and an auth token. Commercial use requires a paid plan starting at $39/month (Starter) or $89/month (Ultimate).

Floci has emerged as the primary community-recommended replacement — an MIT-licensed emulator supporting 20+ AWS services in a 90 MB Docker image with 24ms startup. For more specialized needs, there are also service-specific tools. Below are the best free and open-source alternatives, organized by which AWS services they replace.

Free Tier Removed

After: Non-commercial free tier requires registration and auth token. Commercial use starts at $39/month. CI credits system introduced. OSS projects, students, and nonprofits get free access
