Know if your Postgres will survive your next 10× — in 30 seconds.
Paste your schema. Shard Advisor's rule engine finds the hot tables, unindexed foreign keys, partition candidates and connection-pool risks a DBA would — then writes you a prioritized scale plan with copy-paste SQL.
Free tier is schema-only and runs entirely on your pasted DDL. We never connect to your database.
You're one viral week away from a database fire.
Single-instance Postgres carries most startups a long way — until it doesn't. The failure is never the day you launch; it's the Tuesday a customer 50×'s their usage and a missing foreign-key index turns a delete into a 40-second table lock. A DBA would have caught it. You don't have a DBA.
Hot tables you can't see
Central tables that everything joins to become lock and contention hotspots — and the hardest thing to shard later.
Indexes Postgres won't add for you
Postgres never auto-indexes foreign keys. Cascades and joins silently seq-scan until they don't.
No shard key, no escape hatch
If your tables don't share a tenant boundary, horizontal sharding means a painful rewrite. Better to know now.
Schema in. Scale plan out.
Paste your DDL
pg_dump --schema-only or hand-pasted CREATE TABLEs. Nothing leaves as a credential — it's just text.
We model & score it
The engine parses every table, foreign key and index, detects your shard key, and scores scale-readiness 0–100.
You get a plan
Prioritized phases — quick wins this week, partitioning this month, scale-out this quarter — each with SQL.
A report that reads like advice, not a dashboard.
Monitoring tools show you graphs and leave the thinking to you. Shard Advisor does the thinking — every finding comes with the why and the exact remediation.
🔑 Shard-key analysis
Detects whether a natural tenant boundary (org_id / account_id / workspace_id) runs through your schema, measures its coverage, and tells you what to backfill before you shard.
📇 Index gap detection
Every unindexed foreign key, every jsonb column you might be filtering, surfaced with a CREATE INDEX CONCURRENTLY you can paste.
🗂️ Partition candidates
Spots append-heavy, time-stamped tables (events, logs, audit) and hands you a range-partitioning migration template.
🔌 Connection-pool risk
Flags when you'll hit connection saturation before CPU — with PgBouncer guidance. The deep audit measures it from your real query logs.
