Database Connection String Builder — PostgreSQL, MySQL, Redis, MongoDB

Build a connection string for PostgreSQL, MySQL, Redis, SQLite or MongoDB by filling in host, port, credentials and options through a form — avoiding the URL-encoding mistakes (an unencoded @ or : in a password breaks the whole string) that make hand-writing one error-prone, with each part of the resulting string explained.

How to use Connection String Studio

1. Choose your database type.
2. Fill in host, port, credentials and database name.
3. Review the built connection string with each part explained.
4. Copy it into your app config.

Frequently asked questions

Why does a special character in my password break the connection string?

Characters like @, :, and / have structural meaning in a connection URI — an unencoded special character in the password is parsed as part of the URL structure instead, which is exactly the class of bug this tool avoids by encoding automatically.

Does it support connection options like SSL mode?

Yes — common options (SSL mode, connection timeout, replica set for MongoDB) are supported per database type.

Is my password stored anywhere?

No. The string is built entirely in your browser and nothing is transmitted or saved.
