LocalStack CE Alternatives

In March 2026, LocalStack merged its Community and Pro images, requiring an auth token to pull the latest image. The Community image source code is on GitHub but is no longer regularly updated. The free Hobby plan is for non-commercial use and includes 30+ emulated services.

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.

Restriction

On 2026-03-23 LocalStack ended support for its Community edition. From that date its latest image needed an account and an auth token, and its free plan, Hobby, was for non-commercial use. Commercial use needs a paid plan. Source ↗

Before: Community edition: open source and free for anyone to use, with no account.
After: Hobby, "For hobbyists & other non-commercial usage", free: 30+ emulated AWS services, 1 personal sandbox and test runs in CI, with a LocalStack account and auth token. Commercial use needs a paid plan.
