Trevor is an add-on that enables both your technical and non-technical teams to safely access and query your postgres database data and share the results.
In a nutshell, Trevor:
- provides the power of SQL, in a point-and-click interface.
- gives read-only database access to your team using their Google account.
- lets you export live results into Excel and Google sheets.
- connects to your database using a read-only transaction (so no bad things can happen).
- takes just a minute to set up.
- automatically works out how your tables are connected (using foreign keys and naming conventions).
Trevor also has developer support, including raw SQL snippets and advanced JSON support.
