Managed PostgreSQL, MySQL, and Redis for your apps.
Managed PostgreSQL, MySQL, Redis, and MongoDB for your apps: DATABASE_URL injected on deploy, scheduled backups, safe restores, and AI agent access over MCP.
Managed databases for your apps
Run PostgreSQL, MySQL, MongoDB, and Redis beside your app, or as standalone databases that outlive any deployment. Attach one and the app gets DATABASE_URL on the next deploy. Back it up on a schedule, restore without overwriting, and let AI agents query it with scoped permissions, on NEXUS AI, AWS RDS, Google Cloud SQL, or Azure Database.
Built into your app deployment
Add PostgreSQL, MySQL, MongoDB, or Redis when you deploy an app on NEXUS AI. The database runs beside the app with its own storage, and connection variables such as DATABASE_URL are injected automatically. It lives with that app, so deleting the deployment removes it.
Standalone, attached to any app
Create PostgreSQL or Redis on NEXUS AI, or PostgreSQL and MySQL on AWS RDS, Google Cloud SQL, or Azure Database, as its own resource. Attach it to one or more apps, detach it later, and redeploy or delete apps without touching the data.
Connect a database you already have
Connect an existing PostgreSQL or MySQL database, wherever it is hosted. Inspect the schema, preview a query before it runs, and have AI propose a fix from an error log, from the dashboard or from Claude, Cursor, or Codex over MCP.
Connect Prisma, Next.js, or any framework
Attaching a database injects DATABASE_URL, plus host, port, user, password, and database name, on the next deploy. Point your ORM at the variable, for example url = env("DATABASE_URL") in the Prisma datasource, and the same code runs locally and in production. Redis attaches as REDIS_URL.
Supported platforms
NEXUS AI runs standalone PostgreSQL 17, 16, or 15 and Redis 7, plus PostgreSQL, MySQL, MongoDB, and Redis with app deployments. AWS RDS offers PostgreSQL and MySQL on a public endpoint or a private VPC, Google Cloud SQL offers PostgreSQL and MySQL for Cloud Run apps, and Azure Database offers PostgreSQL and MySQL inside a private VNet.
Create from the UI, CLI, API, or MCP
Use the dashboard for a guided setup, nexus managed-db create and attach for terminal workflows, the REST API for automation, or scoped MCP tools such as nexusai_managed_db_create for agent-operated database infrastructure.
Back up on a schedule, restore without overwriting
Databases deployed with an app back up on demand or on a schedule with pg_dump, mysqldump, mongodump, or a Redis snapshot. Download any backup through a signed link, restore it in place, or restore a Postgres backup into a different Postgres service to test a migration first. Standalone databases take snapshots and restore into a new database, so the source is never touched.
NEXUS AI vs Supabase, Neon, and Heroku Postgres
Choose Supabase for built-in authentication and auto-generated APIs, Neon for serverless Postgres that scales to zero, and Heroku Postgres if the app already runs on Heroku. Choose NEXUS AI when the app and its database should deploy, back up, and scale together. Competitor prices are from each vendor's pricing page, September 2026.
App plus database plus worker
A typical NEXUS AI deployment can run a web app, a PostgreSQL database, a Redis queue, and a background worker as one connected service group. The app and worker share the same deployment network, so application code can use internal hostnames such as postgresql and redis instead of hard-coded host ports or external database addresses.
Storage and recovery included
Production apps usually need more than compute. NEXUS AI supports persistent filesystem volumes for apps that write to paths such as /data, S3-compatible buckets for uploads and generated files, database backups, in-place restore, and restore into another compatible service in the same organization.
One workflow across interfaces
The same stack can be managed from the dashboard, CLI, REST API, or MCP tools. Developers can deploy from GitHub, add database services, attach storage, run workers, scale replicas, inspect logs, create backups, and recover data without switching between cloud consoles and hand-built scripts.

Frequently asked questions
Which databases does NEXUS AI support?
PostgreSQL, MySQL, MongoDB, and Redis can run beside an app deployed on NEXUS AI. Standalone databases are PostgreSQL 17, 16, or 15 and Redis 7 on NEXUS AI, or PostgreSQL and MySQL on AWS RDS, Google Cloud SQL, and Azure Database. MongoDB is only available with an app deployment.
What is the difference between an app database and a standalone database?
An app database is created with a deployment and lives with it, so deleting the deployment removes it. A standalone database belongs to the organization, can be attached to several apps, and keeps its data when apps are redeployed, stopped, or deleted.
How does an application receive database credentials?
Attaching a database injects connection variables such as DATABASE_URL, host, port, user, password, and database name on the next deployment. Redis uses REDIS_URL by default, and the environment prefix can be changed.
How do I connect Prisma or Next.js to a NEXUS AI database?
Point the Prisma datasource at env("DATABASE_URL"). NEXUS AI injects DATABASE_URL when the database is attached, so the same schema works locally and in production. Run prisma migrate deploy in the start command to apply migrations on each deploy.
How are databases backed up?
Databases deployed with an app back up on demand or on a schedule using pg_dump, mysqldump, mongodump, or a Redis snapshot, download through a signed link, and restore in place or into a different Postgres service. Standalone databases take snapshots and restore into a new database without touching the source.
Can I connect a database I already have?
Yes. Connect an existing PostgreSQL or MySQL database to inspect its schema, preview and run queries, and have AI propose a schema fix from an error log. Connecting a database and proposing or applying a fix require database admin permission; reading the schema only needs read permission.
Can AI agents manage databases through MCP?
Yes. Scoped MCP tools let Claude, Cursor, Codex, and other clients create, attach, query, snapshot, restore, back up, and delete databases, and inspect connected databases. The actions use the same organization permissions and audit trail as the dashboard and API.
Is NEXUS AI a Supabase, Neon, or Heroku Postgres alternative?
For apps that need hosting and a database together, yes: NEXUS AI runs the app, its database, workers, and backups in one deployment. Supabase is the better fit if you want built-in authentication and auto-generated APIs, Neon if you want serverless Postgres that scales to zero, and Heroku Postgres if the app already runs on Heroku.
Which plans include databases?
Every plan can run databases with an app deployment on NEXUS AI. Standalone databases need a paid plan: 2 on Starter ($29 a month), 10 on Pro ($149 a month), and unlimited on Enterprise.
Can a database stay on a private network?
Yes. AWS RDS databases can use a private VPC reachable only from App Runner apps, and Azure Database instances are always private inside an Azure VNet. Queries from the dashboard, CLI, and MCP reach private databases without exposing them publicly.
