Application types
Web and worker processes deployed from Git or images.
Platform
The project is the unit of operation, not the container.
Source, runtime, data, networking, deployments and operator actions share one model so the control plane can preserve context across the full lifecycle.
Project graph
Applications and data stay in the same operational picture.
Project environments group applications, databases, caches, volumes and private links. The canvas makes those relationships legible while each service carries its own lifecycle surfaces.
ApplicationsGit repositories and container images with deployment history.
DatastoresPostgreSQL, Redis and plugin-backed services inside the same project.
Private relationshipsLinks between services remain visible without requiring public endpoints.
project / topology
service / deployments01
Project context stays visible as you drill down.
Open a service to manage deploy, stop, restart, rebuild, shell access, process counts and revision history, with logs, variables, networking, metrics and settings beside them.
Extensible runtime
Builders, datastores and services can extend the platform.
settings / integrationsBuild strategies
Dockerfile and builder plugins such as Nixpacks or Railpack can be exposed through the integration layer.
Data services
Database, cache and common service plugins can be installed and managed in-platform.
Runtime architecture
A web control plane over execution engines.
Rails coordinates lifecycle work and host operations, React provides the product surface, and execution happens on Linux hosts over SSH through Dokku and host engines.
Backend
Rails + workers
API, jobs, reconciliation and orchestration.
Realtime
Action Cable
Lifecycle events and changing runtime state.
Execution
Dokku + SSH
Application and datastore operations on your hosts.
Surface
React
Projects, services, data and platform settings.
Go deeper
Understand the model before you automate it.
The docs cover projects, environments, services, servers, networking and reconciliation. The API exposes the same control-plane resources programmatically.
