Analysts using DuckDB often struggle to understand why some queries are fast while others are slow, lacking the visual explain tools available for traditional databases.
Build a web-based visualizer that shows DuckDB's query execution with estimated costs at each step, optimization suggestions, and historical performance tracking. Help users learn the optimizer's behavior.
Monetize through a pro version with team features. Start by parsing and visualizing EXPLAIN output before adding recommendations.
DuckDB's rapid evolution means the tool would need frequent updates to stay current with optimizer changes.
