ADoor vs Railway Postgres
Railway is a platform for deploying apps, where Postgres is a one-click service billed by usage. ADoor, your data account, keeps the records a team or a company shares with apps and assistants like ChatGPT, each with its own access, with Postgres underneath.
Where ADoor stands out
Access to records, not infrastructure
Railway's MCP server manages projects, services, deployments and variables. ADoor's MCP server works with the records themselves, and each assistant gets only the lists and fields you grant.
Capped at the person who connected it
In ADoor, an assistant never gets more than the person who connected it, and it asks before reaching anything new.
No connection string to share
In ADoor, people and assistants sign in with their own access, and revoking takes effect on the next request.

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.
