7777

It creates an SSH tunnel that forwards a remote Amazon RDS instance to a local port 7777, letting developers access MySQL, PostgreSQL, MariaDB, Aurora or Redis databases from standard client tools. The CLI automates the provisioning of a temporary jump server by launching an AWS Fargate container in the same VPC, establishing the tunnel, and deleting the container when the session ends, so no permanent bastion host or EC2 instance is required.

The tool runs on macOS, Linux and Windows and is distributed as a single binary, requiring only a download and execution of the “7777” command. Because the tunnel is created within the user’s own AWS account, no data passes through third‑party services, and the connection can be used with GUI clients such as MySQL Workbench, TablePlus or Sequel Pro, as well as in CI/CD pipelines.

It is aimed at developers who need quick, cost‑free access to private databases for debugging or testing, and it supports unlimited tunnels and databases per license, with solo and team editions available.
