Show HN: SQL-tap – Real-time SQL traffic viewer for PostgreSQL and MySQL
Watch every database query live without touching your application code...
Deep Dive
SQL-tap is a new open-source tool that acts as a proxy between your application and PostgreSQL/MySQL database, capturing and displaying every query in real-time through an interactive terminal UI. It requires zero code changes, uses the native wire protocol, and allows developers to inspect queries, view transactions, and run EXPLAIN commands instantly. The tool can be installed via Homebrew, Go, Docker, or built from source, providing immediate visibility into database traffic.
Why It Matters
This gives developers unprecedented, zero-overhead visibility into production-like database interactions, dramatically speeding up debugging and optimization.
