01 How it works
From the first table to a shared link.
Eight real screens from ViewDB Studio. Keep scrolling to move through the steps, or click one to jump to it.
viewdb.app/projects/e-commerceScroll
01 / 08Your schemas, with table and relation counts at a glance.
02 Features
Arrange it in one click. Then move what you want.
group: color
Groups and sticky notes
Frame related tables in a colored group and leave notes next to them on the canvas.
edit: forms
Edit without writing DBML
Forms for tables, columns, refs, enums and groups change only the lines they touch.
sync: code ↔ diagram
Code and diagram in step
Click a table to jump to its code. Move the cursor and the table lights up.
ref: >
Draw a relation by dragging
Drag from one column to another and the ref is written for you.
import: ≤ 900 KB
Start from the SQL you have
Paste CREATE TABLE statements from PostgreSQL, MySQL or SQL Server, up to 900 KB.
03 AI assistant
Ask about the schema. Approve every change yourself.
The assistant reads your current DBML. Ask it to explain the model, suggest improvements or fix errors. Changes come back as a proposal you compare line by line, and nothing is written until you press Apply. Ctrl+Z takes it back.
- Pro includes 200 messages a month on the built-in Gemini model.
- Bring your own Gemini, OpenAI or Anthropic key and there is no monthly cap. The key is stored encrypted.
04 Agents over MCP
Your coding agent can edit the schema too.
ViewDB runs an MCP server with 10 tools. Claude, Claude Code and Cursor can list your projects, read the schema, export code and change tables. ViewDB saves a version before the agent starts editing.

Version saved before agent edits
05 Version history
Go back to how the schema looked this morning.
ViewDB saves 1 second after you stop typing and keeps a version every 10 minutes. It also keeps one before imports, restores, agent sessions and assistant changes.
- Name the versions that matter
- Compare any version with the current schema
- Restore it, then undo if you change your mind

Questions before you start.
Do I need to learn DBML?
No. Paste SQL and ViewDB writes the DBML for you. Forms edit tables, columns and refs without code, and the help page has a DBML guide when you want it.
Can ViewDB connect to my database?
Not yet. Export the CREATE TABLE statements from PostgreSQL, MySQL or SQL Server, then paste or upload them.
What happens when the trial ends?
Your account turns read-only. You can still open your projects, download DBML and .viewdb files, and your share links keep working. Choose a plan to edit again.
Where does my AI key go?
It is encrypted with AES-256-GCM before it is stored, and it is only used for your own assistant requests.
How do I cancel?
From Account, Billing, through the Stripe customer portal.
