dbt Cloud Catalog
Great if you run dbt Cloud. Not available if you run dbt Core on premises. Taavik fills that gap with a tool that observes the actual database, not the dbt model.
Database documentation tool
A database documentation tool that does not go stale.
Most database wikis are wrong within a week of being written, and everyone on the team quietly knows it. Taavik makes the documentation a function of the schema instead of a chore somebody owes: the agent scans, the diff rewrites the page, and the change history records when it happened. Whatever you wrote by hand stays exactly where you put it.
What teams need from a database documentation tool
Three jobs the wiki cannot do anymore.
Confluence, Notion, dbDocs, an ER diagram in Lucidchart. Different tools, same weak point: every one of them waits for a human to remember. After the third missed migration people stop trusting what the page says, and once trust is gone the page is dead whether or not anyone deletes it.
Auto-update from the schema
A scan picks up a new column and the page shows it. A column disappears and the page drops it, with the change history keeping the date it happened. Nobody synchronises anything.
Preserve manual notes
The technical metadata is generated. The prose paragraphs are yours. Auto-updates touch the metadata only and never overwrite a description.
Built-in change history
Every scan produces a diff. The doc shows the most recent changes per object, so a new hire reads the present and the recent past in one place.
Works on private databases
The agent runs on a host inside your network and the cloud receives the catalog, which is usually enough for compliance to stop asking difficult questions.
Where Taavik fits
If you tried these and they did not work.
DataHub or OpenMetadata self-hosted
Powerful, but require half a person to operate. Taavik is a single agent and a hosted control plane that keeps documentation alive without dedicated operators.
dbDocs and ER diagram exports
Static snapshots. Useful for a one-shot deliverable, painful as living documentation. Taavik refreshes on every scan and never asks you to re-run the export.
Confluence and Notion pages
Easy to start, hard to keep current. Taavik moves the technical metadata to a tool that updates itself. Your wiki keeps the high-level prose; Taavik keeps the schema accurate.
What is supported
PostgreSQL, SQL Server, MySQL, Amazon Redshift.
One workspace, many connections, many engines. Provider quirks normalized at scan time, the documentation reads consistently across databases.

Database documentation tool for PostgreSQL, MySQL and SQL Server
Which databases are supported? +
PostgreSQL, MySQL, SQL Server, and Redshift. The on-premise agent connects to any of them and reads schema metadata through the standard information schema.
Where is my data stored? +
The control plane runs on dedicated virtual machines inside the European Union. What it holds is the catalog, your manual notes and the change history. The rows in your tables stay in your network.
Is the documentation hosted on Taavik or self-hosted? +
The documentation is rendered in the workspace, served by the cloud control plane. The data behind it is catalog metadata, manual notes, and change history. Credentials stay local.
Can I edit the documentation manually? +
Yes. Add descriptions to tables, paragraphs to columns, known-issue blocks to objects. Auto-updates touch only the technical metadata; your text stays untouched.
Does Taavik replace dbt docs? +
Taavik documents the database as it is. dbt docs documents the dbt models you wrote. They serve different audiences. Many teams use both.
Try it
Generate the first documentation in under ten minutes.
Free for one connection, forever. The agent is small enough that the first scan is usually done before you have finished reading the setup page.
