Frequently asked questions

Welcome! This page answers common questions about Centia.io and points you to the right docs to go deeper.

What is Centia.io?

Centia.io is a Backend as a Service (BaaS) that provides data, auth, realtime, file storage, and developer tooling so you can focus on shipping your app. Start with the data model you define, connect with an SDK, and add realtime where you need it.

How do I get started?
  1. Sign in and create a backend in the Console: /console
  2. Follow the Getting started guide to model your first schema and table: /docs/start
How do I model my data?

Use the CLI to define schemas, tables, columns, and constraints. For example: 

centia schema add "app"
centia table add "app" "users"
centia column add "app" "users" "id" int
centia constraint add "app" "users" "id" primary
See the full walkthrough: /docs/start

How do I read and write data from my app?

Use the official SDKs to connect from web or server code: /docs/sdk. You can also issue SQL via the CLI during development.

Does Centia support realtime updates?

Yes. Subscribe to changes and build reactive UIs (chat, live dashboards, collaborative features). Learn more: /docs/realtime

How does authentication work?

Centia supports OAuth so you can authenticate users and integrate identity providers. Overview: /docs/oauth

Can I store and serve files?

Yes. Use Objects to store and serve files alongside your data. Docs: /docs/objects

Which platforms and clients are supported?

See the SDKs overview and available clients here: /docs/sdk and /docs/clients

Is Centia open source or can I contribute?

Centia focuses on open, developer‑first tooling and familiar SQL workflows. Learn more on the Open source page: /docs/opensource

How is Centia different from other BaaS platforms?

Centia lets you model data explicitly (schemas, tables, columns) and query with standard SQL, adds realtime where you need it, and provides OAuth and file storage out of the box. Check the Intro for a quick overview: /docs/intro

Can I migrate in or out of Centia?

Your data model is defined with familiar SQL concepts, and you can interact via SQL and SDKs. This makes it straightforward to import seed data during setup and to export data later using the CLI and SQL queries.

Are there limits, quotas, or pricing tiers?

Right now we are in beta and there are no pricing tiers. Limits are:

  • 10 tables
  • 10 Sub-users
