# Cohesivity vs Firebase

Firebase: “A platform of services to help you and AI agents build and run intelligent apps.”

Firebase wants a Google account before anything happens. You sign in, open the console, create a project, and only then does the app get a database, auth, or storage. For a lot of teams that is fine, because they already live in Google's world.

Firebase is one of the most proven app platforms there is. Firestore, Authentication, Cloud Storage, Cloud Functions, Hosting, years of production behind it, and deep ties into the rest of Google. Cohesivity is not trying to out-Google Google. It runs one HTTP API that a coding agent calls to provision the backend as it builds, with no account and no console. The project runs for 72 hours, then you claim it. So the real question is whether a human signs into a console first, or the agent just does it.

where Cohesivity fits

- No Google account, no console. The agent provisions the backend as it builds, so there is no sign-in and no project setup before the app can store data.
- Postgres instead of Firestore. If you would rather have a relational database than a document store, Cohesivity provisions managed Postgres by default.
- The whole backend from one API. Storage, a vector store, hosting, auth, an AI gateway and a browser come from the same place, without opening a console for each.

when Firebase is the better call

Pick Firebase if you are already in Google's ecosystem. The integration with Google Cloud, Analytics, and mobile SDKs is deep, and if your app is Android-first or Google-first, that gravity is real and worth a lot.

Pick Firebase if you want its realtime document model. Firestore's live listeners and offline sync are excellent for chat, presence, and collaborative apps, and it has scaled to enormous workloads for years.

This is a database-shape and ecosystem decision as much as a signup one. If you want NoSQL, Google integration, and a console a person will happily use, Firebase is the mature choice for exactly that.

questions

### Is Cohesivity a Firebase alternative?

For the case where you want an agent to stand up a backend with no Google account and no console, yes. Cohesivity provisions a managed Postgres database plus storage, auth, hosting and AI over one API, and you claim the project later. Firebase is Google's app platform, built around Firestore, that you sign into and configure yourself.

### Does Cohesivity use Firestore or Postgres?

Postgres. Cohesivity provisions a managed relational Postgres database. Firebase's main databases are Firestore and the Realtime Database, which are document stores, not relational.

### Do I need a Google account like Firebase requires?

No. A new Cohesivity project runs 72 hours with no account and no card, so the agent can build immediately. You claim the project with one approval to keep it.

### Can my agent set up the backend without me opening a console?

Yes. The agent creates a project and provisions services with HTTP calls. There is no console step. Firebase requires a Google sign-in and a console project first.
