ADoor vs Render Postgres
Render is a cloud platform for hosting apps, with managed Postgres from a free instance up. 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
Data that stays
Render's free Postgres instance expires 30 days after it's created. ADoor's free plan holds 3 tables and 100 rows, and Pro is $10 a month per workspace.
Access per assistant
Render's MCP server authenticates with an account API key, or OAuth in some clients. In ADoor, each assistant has its own access, down to one field, capped at the person who connected it.
Approvals
In ADoor, agents ask for more access and you approve or deny. New devices sign in only after you approve them.

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.

Which one should you use?
Use Render Postgres when
you're hosting an app on Render and want its database next to it.
- App hosting. Web services, workers and databases in one place.
- Simple instance pricing. Postgres plans at fixed monthly prices.
- MCP for your infrastructure. Manage Render resources from an assistant.
Use ADoor when
the records outlive any one app, and people and assistants need their own limited access.
Technical
- A Render cron job writes daily reconciliation results to an add-only list, and finance reads it in SQL.
- An agent that answers billing questions reads Invoices and asks before reaching Customers.
- A Cursor agent reads a Services list with owners and runbooks, and adds entries but never deletes them.
Personal
- Bills and due dates for the household, shared with your partner, who marks what's paid.
- Your art prints: editions, buyers and which ones have shipped.
Team
- Engineering, finance and support share a Credits list: support adds, finance approves.
- A history of changes shows who approved each credit and what it was before.
- An ops team keeps an On-call list where each person edits only the shifts with their name.
Business
- Account managers edit their own accounts (one grant per person); only finance sees Payment terms.
- An auditor gets read access for a month, then you revoke it.
- A school keeps equipment loans in one list; teachers add, the office edits Returned.
