Real-time database-centric backend
Use Instant as the backend for a frontend app, with real-time data access instead of a separate endpoint layer.
InstantDB
BeanspruchenInstantDB is a backend platform for frontend and AI-assisted apps, with a real-time database, built-in auth, permissions, storage, presence, and streams.
Overview
InstantDB is a backend platform for AI-coded and frontend-heavy applications. It centers the app on a real-time database and exposes capabilities such as auth, permissions, storage, presence, and streams so teams can build without stitching together multiple separate services.
The product is positioned for developers working with agents or CLI-driven workflows. The site emphasizes terminal-based setup, schema pushes, undo for destructive changes, and type safety for schemas, permissions, queries, and transactions.
Core capabilities
Built-in auth options
Set up authentication with magic code emails and sign-in providers including Google, Apple, GitHub, and LinkedIn.
Permission rules
Define permissions with rules that control who can view, create, update, and delete records.
Storage for files
Store files such as images and videos in the same product, so uploads live alongside database records.
Presence and broadcast
Share who is online, who is typing, or cursor movement with presence and broadcast features.
Streams for large data
Push large data streams without managing RAM or durability yourself, using the streams service.
Common use cases
Start a full-stack product
Build a new app where the frontend needs direct access to live data, authentication, and file uploads without assembling separate services first.
Agent-assisted development
Use the CLI to scaffold an app, push schema changes, and let an agent help generate or modify the code from the terminal.
Live collaborative interfaces
Create collaborative experiences such as chat, dashboards, or apps with online presence and typing indicators that update in real time.
Rule-based data access
Add permissions and ownership rules when different users need different access to records, edits, or deletions.
Prototype and scale over time
Ship a small project on the free tier or choose a paid plan when you need more storage, support, team members, or backups.

FAQ
How do you get started with InstantDB?
Instant provides a terminal-first setup flow through `instant-cli`. The tutorial shows logging in, scaffolding a starter app, and then deploying the app after building it locally.
What kind of apps is InstantDB meant for?
The docs show support for React-based apps, with setup examples for Next.js and Vite React. The tutorial also describes using the CLI to scaffold, push schema changes, and deploy.
How does InstantDB fit into the app workflow?
Instant is designed around a frontend that talks directly to a real-time database rather than separate CRUD endpoints. The homepage and docs emphasize queries, transactions, permissions, auth, storage, presence, and streams.
Does InstantDB have a free plan?
The pricing page lists Free, Pro, Startup, and Enterprise plans. Free projects are never paused, and commercial use is allowed on the Free plan.
What should teams know about pricing and limits?
The pricing page says storage counts toward database space, and higher tiers add features such as priority or Slack support, more team members, and longer backup retention.
