Supabase DB Visualizer

Paste connection string. Ship schema changes with confidence.

Open dashboardBuy for $12/mo

Supabase DB Visualizer gives solo builders a universal schema cockpit: ERD diagram, searchable schema explorer, safe query runner, and slow-query tracking in one place.

Tooling friction across projects

Switching between pgAdmin and multiple Supabase Studio tabs creates context loss every time you debug schemas.

No shared ERD source of truth

You can ship migrations quickly, but reviewing foreign key drift and relationship impact is still manual and slow.

Slow query feedback arrives too late

Performance regressions usually surface after deploy because solo founders lack a lightweight query diagnostics loop.

Built for multi-db solo workflows

No desktop clients. No project lock-in.

Auto ERD generation

We introspect `information_schema` and draw an interactive entity-relationship map in seconds.

Schema browser with row counts

Scan tables, columns, PK/FK markers, and live row estimates from one searchable pane.

Read-only query explorer

Run `SELECT`, `WITH`, and `EXPLAIN` safely, format SQL, preview result sets, and track slow statements.

Slow query log

Durations are captured per run so you can watch where latency is rising before users feel it.

Server-side connection handling

Connection strings are used only for API calls in your deployment, not exposed in client-side libraries.

Zero install workflow

Paste URL, inspect schema, run diagnostics, move on. No desktop setup, no local driver maintenance.

Simple pricing, solo-founder friendly

One plan for builders running 2-5 Supabase projects. Keep schema visibility centralized and stop paying with debugging time.

How it works

  1. 1. Paste your Supabase Postgres URL.We test connectivity from the server and confirm metadata.
  2. 2. Inspect generated ERD and schema.View PK/FK structure and row counts without opening multiple tools.
  3. 3. Run diagnostics queries.Format SQL, execute safe reads, and watch slow-query timings over time.

FAQ

Can I use this for multiple Supabase projects?

Yes. Each session can connect to any PostgreSQL-compatible Supabase database by pasting its connection URL.

Does this mutate my database?

The explorer enforces read-only query types (`SELECT`, `WITH`, `EXPLAIN`) so the built-in runner avoids write operations.

How is access controlled after payment?

Checkout happens on Stripe hosted checkout. After purchase, access is unlocked with an HTTP-only cookie for the dashboard.

Do I need a local install?

No. The app is fully browser-based and cloud-native, designed for solo founders jumping between databases quickly.
