Eligibility Criteria

Projects must meet the following requirements:

Non-Commercial: The project must not be owned or maintained by a for-profit entity and must not generate revenue (e.g., through paid versions, commercial support or proprietary add-ons). While the project should not generate revenue through commercial sales, community-based financial support—such as donations, GitHub Sponsors, or Open Collective—is fully permitted and will not disqualify your application.
OSI-Approved License: Your project must be licensed under an Open Source Initiative approved license (e.g., MIT, Apache 2.0, GPL).
Publicly Accessible: The source code must be available in a public repository (e.g., GitHub, GitLab) with a publicly accessible website or documentation.
Active Development: The project should show signs of active maintenance (e.g., commits within the last 3-6 months).
Community Focus: The project should be intended for public use and contribute to the broader developer ecosystem.

Supporting the Ecosystem

If your application is approved, we encourage you to acknowledge our support in a way that feels natural to your project:

README Badge

Add a "Tested with LocalStack" or "Supported by LocalStack" badge to your project’s repository.

Project Website

Include the LocalStack logo in your "Supporters" or "Sponsors" section.

Social Media

Give us a shout-out on social media, for example when you announce a new release that used LocalStack for testing!
