How to Use

Select your database type from the dropdown (MySQL, PostgreSQL, SQLite, or SQL Server).
Enter the connection details: host, port, username, password, and database name.
Click the 'Test Connection' button to initiate the connection test.
View the results which will show either a success message with server details or an error message explaining what went wrong.
For SQLite databases, you only need to provide the database file path instead of host/port.

Frequently Asked Questions

Find Quick Answers

What database types does this tool support?

The tool supports MySQL, PostgreSQL, SQLite, and Microsoft SQL Server databases.

Is my database connection information secure?

Yes, all connection tests are performed server-side and credentials are not stored or logged. The connection is established temporarily only for the test and then immediately closed.

Why is my connection failing?

Common reasons include incorrect credentials, firewall blocking the port, database server not running, or network issues. The tool provides specific error messages to help diagnose the problem.

Can I test a remote database server?

Yes, as long as the server is accessible from our testing environment and the port is open. Some hosting providers may block external connections for security reasons.

Do I need to install anything to use this tool?

No, this is a completely web-based tool. However, for the backend to work, the server needs PHP with PDO extensions for the supported database types.
