Deployment model: pgDash offers SaaS and self-hosted; MonPG is SaaS with an in-VNet collector.
Diagnostics style: pgDash scans and reports issues across ~25 subsystem areas; MonPG ranks what changed and what to do about it during an incident.
Index workflow: pgDash flags unused and bloated indexes; MonPG additionally models rollout risk (table size, write load, replicas) before you run the DDL.
Pooler visibility: pgDash integrates PgBouncer and Pgpool metrics natively; MonPG covers the database side.
Time-to-first-signal: both connect to a live database in minutes; compare them on a real incident, not the onboarding demo.
Pricing transparency: pgDash pricing is tiered per server (check pgdash.io for current numbers); MonPG pricing is on the public pricing page.
