Neon has launched its serverless Postgres database service, removing the need for invite codes and allowing users to sign up instantly using Google or GitHub accounts. The service offers a free tier with availability in major regions, including the US, Europe, and Asia Pacific, and provides features like database branching, which enables users to create multiple branches for different environments, each with a limit of 3 GB of data. The platform also includes an API for managing projects and databases, allowing for automation and integration with CI/CD workflows. Users can create branches, run tests, and revert changes using point-in-time resets, while the Neon API facilitates project management and can be used for local development and CI/CD integrations. Neon is actively engaging with its community through forums, developer events, and social media, inviting feedback and collaboration.
