Webiny

Webiny is an open-source serverless CMS that runs on AWS Lambda, designed for companies that want to avoid traditional hosting. It includes multi-tenancy from the ground up, so you can manage many content properties in one install. Approval workflows and permissions are built in, making it suitable for editorial teams.

Webiny works well for AWS-native teams and organizations that need multi-tenant content infrastructure without the cost of enterprise platforms. It's also good for agencies managing many client sites. The serverless approach keeps costs low for variable traffic, though setup is more technical than managed alternatives.
