ADoor vs Prisma Postgres
Prisma Postgres is a managed serverless Postgres from the makers of the Prisma ORM, billed per operation. ADoor, your data account, keeps the records a team or a company shares with apps and assistants like ChatGPT, each with its own access.
Where ADoor stands out
Access per list and field
Prisma's MCP server connects after you sign in with your Prisma account. In ADoor, an assistant gets only the lists and fields you grant, and never more than the person who connected it.
No schema or ORM
In ADoor you describe what to keep in an assistant like ChatGPT, and the list is set up, ready to query in SQL.
A history of changes
Prisma Postgres keeps 7 days of daily backups on paid plans. ADoor keeps a history of changes, with who made each one and the before and after.
The products
Prisma Postgres
Prisma Postgres is serverless Postgres with many databases per account.
- Assistants
- A remote MCP server at mcp.prisma.io/mcp
- Backups
- 7-day daily backups on Starter and above
- Plans
- Free with 200,000 operations a month. Starter is $10 a month.
ADoor
ADoor is your data account. You keep lists and tables in a workspace you own, personal or team: a reading list, an incident log, a list of customers. Describe what you want to keep track of and it's set up for you, with real Postgres underneath. Every person, app, assistant, device and job gets its own access.
- Assistants
- ChatGPT, Claude, Grok and Cursor connect through MCP with a sign-in.
- Apps and scripts
- An HTTP API with keys, running the same actions assistants use
- Access
- Per space, list or field, or just the entries where a field equals a value you choose. Reading, adding, editing and deleting entries, and changing a list's fields, are separate permissions. An assistant never gets more than the person who connected it.
- Approvals
- Agents ask for more access and you approve or deny. A new device signs in only after you approve it and choose its access.
- CI jobs
- GitHub Actions signs in with short-lived access, 15 minutes by default and up to 30 days, with no stored secret.
- Revoking
- Takes effect on the next request. What was already saved stays.
- History
- A history of changes, with who made each one and the before and after
- Underneath
- Standard Postgres
- Plans
- Free for 3 tables and 100 rows. Pro is $10 a month per workspace, with 1 GB of storage.
