For Rails teams running Postgres in production
Know why your queries got slow
after Friday's deploy.
See which deploy broke your queries. Catch N+1s in production, not just development. Get a daily health score instead of guessing if Postgres is misconfigured. One gem. Five minutes to install. Starting at $39/mo.

Deploy → mystery slowdown
You shipped on Friday, queries tanked on Saturday. Without deploy-correlated monitoring, you're guessing which commit caused it.
N+1s hiding in production
Bullet catches N+1s in development. Nobody catches them in production where real data and traffic patterns expose the ones that actually matter.
Postgres is misconfigured
Your random_page_cost is still set for spinning disks. Your work_mem is the default. These silent misconfigs cost you 10–50% of your query performance.
Stuck between free and $149/mo
pgHero is too basic. pganalyze is $149/mo and not even Rails-native. There's nothing in between for small teams that need real Postgres depth.
What Lantern gives you
Health score
A single 0–100 score for your Postgres instance. Slow queries, unused indexes, cache hit ratio, autovacuum health, connection saturation — all in one number you can check daily.
Query trends
14-day performance history for every query. See which ones are degrading before they become incidents.
Deploy correlation
Drop in a webhook from GitHub Actions, Render, or Fly.io. See exactly which deploy caused which regression. No competitor under $149/mo does this.
