Everything behind one API

The parts of a backend you would otherwise assemble from separate services, in one platform you run yourself.

01 Data
Model data as components with schemas, validation and access policies. Query records, build views and follow the events feed.
02 Functions
Write JavaScript functions and run them in an isolated engine, called from your app, a workflow or a signed public URL.
03 Workflows
Visual workflows with sync and async triggers, component events, dry runs, and run control down to a single node.
04 Integrations
Install integrations, connect external databases, and run integration code on your own satellites.
05 AI Coming soon
Agents, chat, knowledge bases and OCR using your own model provider keys.
06 Apps
Deploy frontend apps on their own domains, with app-scoped tokens and permissions.
07 Files
Storage with folders, sharing, retention policies and public serving.
08 Identity
Users, roles, API keys, two-factor sign-in and a full OAuth 2 provider for your apps, the CLI and MCP clients.

Also inside Inbox over IMAP and SMTP · Read-optimized collections · Audit logs · Secrets with keyring encryption · MCP server for AI clients

Coming soon AI with your own model provider keys · A marketplace for integrations and apps · A one-command installer

Start on a single VM with Docker Compose and automatic TLS, or deploy to Kubernetes with Helm. Your data stays in your infrastructure.
