ADoor vs Supabase
Supabase gives developers a Postgres project with sign-in, file storage, realtime and server functions, to build an app on. ADoor is the data account where a company, a team or one person keeps the records they work from. You set it up from a chat with an assistant like ChatGPT, and every person, app and assistant gets its own access. ADoor itself runs on Supabase.
Where ADoor stands out
Real SQL with nothing to set up
Ask an assistant like ChatGPT to keep track of your open deals, and ADoor starts a Deals list you can query with standard Postgres SQL right away. There's no project to create and no policies to write. On Supabase, each table in an exposed schema needs Row Level Security policies, written in SQL, before an app can use it safely.
Access for every agent, already built
Supabase's MCP server works with your developer permissions, and Supabase advises against giving it to customers or end users. In ADoor, each person, app, assistant, device and CI job has its own access, down to specific fields, or just the entries that match a value you choose, and an assistant can never exceed the person who connected it.
A history of changes, before and after
ADoor keeps a history of changes, with who made each one and the before and after, whether it was a person, a script or an assistant. Supabase Pro keeps daily backups for 7 days, and point-in-time recovery is an add-on at $100 a month per 7 days.

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 Supabase when
you're building an app, and you want its data, sign-in and files in one project you control.
- Your own app and users. Supabase Auth, Storage and Realtime come with every project. Login with ADoor is coming soon, for signing in your app's users, and ADoor has no file storage.
- Direct access to Postgres. Connect psql, Prisma, Drizzle or any Postgres client with a connection string.
- Self-hosting. Run Supabase yourself with Docker or the CLI. ADoor is hosted only.
Use ADoor when
you want real Postgres SQL across your company's data, with access for every person, app and agent already built, and no project, schema or policies to set up first.
Technical
- Your production service writes every signup and payment event to an Events list with an add-only key. Analysts query it in SQL, and nobody can rewrite what happened.
- A GitHub Actions deploy job records each release with 15 minutes of access and no stored secret. On Supabase, CI holds a personal access token.
- A Cursor agent in production reads the runbook list and logs what it did. When it needs another list, it asks and you approve or deny.
Personal
- You keep your father's medications, doses and refill dates, and share that one list with your sister. She sees it and nothing else in your space.
- Your car's service history lives in ADoor. At the garage you ask ChatGPT on your phone when the brakes were last done.
Team
- One incident log across engineering, support and sales. Engineers edit, support reads, and the incident bot adds entries but can't delete one.
- Customer call notes keep a history of changes, with who made each one and the before and after. You don't build an audit trail.
Business
- A client list where your assistant adds contacts and only you see the Rate field. On Supabase, that's a policy you write and test.
- An agency gets one space for its campaign tracker. When the contract ends you revoke it, and everything it added stays.
Questions people ask
Is ADoor built on Supabase?
Yes. ADoor runs on Supabase. You don't need a Supabase account to use it.
Can I use both?
Yes. Keep your app on Supabase and your team's shared records in ADoor. ADoor doesn't sync with other services, so data moves through the ADoor API or an assistant.
Which assistants work with ADoor?
ChatGPT, Claude, Grok and Cursor connect through MCP with a sign-in. You approve each one and choose what it can reach.
