Rebase vs Payload CMS
Payload runs inside your Next.js app and ships with it — one codebase, one deploy. Rebase is a backend that stands on its own, in front of a Postgres you own, serving several clients at once. If your product is a Next.js site, that is Payload's advantage; if it is an API with a web app, a mobile app and an ops team on it, it is the thing to weigh.
Generating a database, or reading one
Where it hurts
Payload is a code-first system designed to start from a clean slate. Pointing it at a large legacy database means recreating that structure by hand in its config.
What Rebase does instead
Rebase starts from data that already exists.
- Point it at your existing Postgres and introspection maps the tables, columns, foreign keys and enums it finds.
- Rebase generates the API, the typed SDK and the panel from your existing schema without breaking the apps already on it.
Code only, or code the panel can write
Where it hurts
Because Payload is strictly code-first, a small schema change — a published_date field, a different validator — is an IDE, a PR and a redeploy.
What Rebase does instead
Rebase lets the rest of the team move without waiting on an engineer, and still commits the change.
- Rebase Studio allows visual schema edits directly from the panel.
- AST manipulation writes the TypeScript change back into your repository, leaving your own callbacks untouched.
- Developers still get schema-as-code; the change still arrives as a diff.
An abstracted database, or a visible one
Where it hurts
Payload abstracts the database away, for broader MongoDB and SQL compatibility. On a Postgres-heavy internal tool that means the Postgres tooling is not in the panel with you.
What Rebase does instead
Rebase builds for Postgres specifically, and puts those tools in the panel.
- A SQL console that queries the tables directly.
- EXPLAIN on the spot, so an expensive query is visible while you are still writing it.
- A visual editor over real row-level security policies.
Do not switch
When to stay on Payload
When you are building a content-heavy site in Next.js and want the CMS to live in the same codebase and deploy. That is a genuinely good architecture and Rebase does not replicate it. Rebase fits better when the backend has to stand on its own — several clients, a team that is not all frontend developers, or authorization that has to hold at the database.
Rebase and Payload, answered
Do I have to use Next.js?
No. Payload is designed to live inside a Next.js application, which is a real advantage if that is your stack. Rebase runs as its own backend and serves any client — React, Vue, mobile, another service — over a REST API and a typed SDK. If you are already all-in on Next.js, Payload's integration is tighter; if you are not, Rebase does not ask you to be.
Can Rebase work with an existing Postgres schema?
Yes, including one that predates it. Rebase reads the tables it is pointed at and generates the API and the admin panel from collection definitions you write against them. It does not require ownership of the database and does not maintain a schema of its own alongside yours.
What about rich content editing?
Rebase ships a block editor in its CMS layer, alongside forms, media handling and roles. Payload's content modelling — nested blocks, localisation, versioning of editorial content — is deeper, and if the product you are building is fundamentally a publication, that depth is the thing you are buying.
When is Payload the better choice?
When you are building a content-heavy site in Next.js and want the CMS to live in the same codebase and deploy. That is a genuinely good architecture and Rebase does not replicate it. Rebase fits better when the backend has to stand on its own — several clients, a team that is not all frontend developers, or authorization that has to hold at the database.
Where does authorization live?
In PostgreSQL. Collection access rules compile to row-level security policies, which the database applies to every query regardless of which client sent it. Payload enforces access control in application code, which is expressive and easy to reason about, but it is only in force for requests that go through Payload.
Do I have to self-host Rebase?
No. Self-host it and you own the data, the code and the machine it runs on — that is the default and it is fully supported. Or deploy the same project to Rebase Cloud, which is live with real tenants today and opening in batches while it is in private beta, priced per resource rather than per seat. Your code is identical either way; hosting is a deployment target, not a fork.
Don't take our word for it.
The comparison that matters is the one you run. Point Rebase at a Postgres database you already have and see how it holds up next to Payload.
