AI Analysis

●●SolidSolve My ProblemWizardryDark Horse

Wire-protocol parsing needs zero code changes; competes against established query inspectors.

Strengths

•Zero-code integration (just change database port) via native wire protocol handling is genuinely elegant.
•TUI with EXPLAIN capability and transaction inspection is thoughtfully designed.
•Works with PostgreSQL, MySQL, and TiDB out of box.

Weaknesses

•Query inspection/EXPLAIN tools exist (pgAdmin, Datadog, MySQL Workbench); transparent proxy doesn't differentiate.
•Early stage: minimal docs, no Windows support mentioned, limited error handling examples shown.

Post Description

sql-tap is a transparent proxy that captures SQL queries by parsing the PostgreSQL/MySQL wire protocol and displays them in a terminal UI. You can run EXPLAIN on any captured query. No application code changes needed — just change the port.
