Cross-Database Query Tool for Business Intelligence
Developers and analysts struggle to join data across multiple databases with different systems (e-commerce, accounting, CRM). A GitHub feature request has 5,811 upvotes, indicating massive demand for a tool that enables SQL-like joins across heterogeneous databases using common keys like email addresses or order IDs.
Real Evidence
“Feature: Join across multiple databases For example, if I have an e-commerce system in one database, and an accounting system in another database (not necessarily using the same driver), I'd like to be able to build queries to join the data using the email address or order number as the key.”

Suggested MVP
Build a web-based query builder that connects to 2-3 popular databases (MySQL, PostgreSQL, MongoDB) and allows users to define joins using common fields. Start with simple SELECT queries with basic filtering and export to CSV.
Distribution Strategy
Target indie hackers on Twitter and GitHub by building in public, create content about solving data silos, and reach out to the 5,811 users who upvoted the original GitHub issue. Consider freemium model with limited queries/month.
