Ask your own database. It stays where it is.
Connect Postgres, BigQuery, Snowflake or MySQL with a read-only user. Cerebro learns the schema and queries it live, from fixed IPs you allowlist once.

Four engines, queried in place
43 live database connections run on Cerebro today. Each one is queried directly. Nothing gets loaded into another warehouse first.
Postgres
Self-hosted or managed. Connects from static egress IPs you allowlist.
BigQuery
Queried in place in your Google Cloud project.
Snowflake
Key-pair or password sign-in. Query your modeled tables directly.
- SQL
MySQL
Queried in read-only transactions, from static egress IPs.
It reads. It never writes.
Every connection is read-only. Cerebro checks each statement before it runs and blocks anything that would change data, whether a person wrote the query or the analyst did.
Add a read-only database user and your firewall allowlist, and a write would have to get past all three.
- Statements checked before they run
- A short, fixed list of IPs to allow
- Change schemas later without re-entering credentials

The analyst learns your schema before you ask
After you connect, Cerebro profiles the tables and columns, works out how they join and writes a short description of each. That's what lets you ask about "accounts that have gone quiet" instead of naming tables.
Two databases with a schema called public? Each query goes to the right one.

A rep's call list, straight off the ERP
Keystone Office Supply keeps its ERP in Postgres. An outside consultant connected it read-only and built Dana's morning list on top: who to call, which accounts are slipping against last year and who has gone quiet. The list runs against the live database, so a call logged this morning shows up on the next refresh.

Good morning, Dana.

Databases FAQ
Which databases can I connect?
Postgres, Google BigQuery, Snowflake and MySQL. Snowflake connects with a key pair or a password.
Does Cerebro copy my data?
No. Queries run against your database when someone asks a question or opens a dashboard. There's no second copy to keep in sync.
Can Cerebro write to my database?
No. Connections are read-only and Cerebro rejects statements that would change data. Connect with a read-only database user as well, so the database enforces it too.
What do I add to my firewall?
For Postgres and MySQL, the static egress IPs shown in the connect form. Cerebro connects to your database from those addresses.
Which plan do I need?
Your own databases are available on Growth plans and up. Connectors for apps like your CRM and accounting system work on every plan.

What customers say
“Even if the data's wrong, someone like me can go in, find what's wrong and fix it through the CLI. The iteration cycle is now a day or two. It's amazing.”
“I had to search through thousands of records today for something that isn't easily searchable in Zoho, and Cerebro did it very quickly and then gave me the SQL code that I could run myself to generate a report to share with the client for verification.”
“We could delete Looker in about a month.”
