Score: 6.0/10 (Innovation: 5, Technical: 5, Documentation: 8, Utility: 6)

Slotwatch is a terminal UI for monitoring PostgreSQL replication slots, showing retained WAL, growth rate, idle time, and health warnings to prevent disk fill from stuck consumers. It offers interactive and check-mode interfaces with sensible alerts, filling a small but real observability gap for Postgres operators.

Target audience: devops, backend devs, database administrators
