Frontend services
WebThe main application interface where users interact with projects, work items, and pages. This service serves the UI and handles client-side routing. Space
This powers public sharing. It lets you publish projects, views, pages to the web, so others can view without needing to log in. Admin
Instance administration interface for workspace owners and administrators. Manages billing, licensing, workspace settings, and user permissions.
API server
APIThe core REST API that handles all data operations. All frontend services communicate with this API for creating, reading, updating, and deleting data. Worker
Background job processor that handles async operations like file processing, notification dispatch, and data imports. Workers pull jobs from RabbitMQ and execute them independently. Beat worker
Scheduled task executor that runs periodic jobs like data cleanup, report generation, and reminder notifications. Uses a cron-like scheduling system. Migrator
Database schema management service that runs on deployment to apply schema changes and data migrations. Runs once during upgrades then exits.
Supporting services
ProxyHandles incoming traffic and routes it to the appropriate services. Manages certificates and reverse proxying. In Docker deployments, Plane uses Caddy for automatic SSL certificate management and traffic routing. Live
Real-time collaboration service powered by WebSockets. Handles cursor positions, live updates, and presence indicators for multiple users working simultaneously. Monitor
Used for license validation and activation. It checks the license status and ensures your instance is compliant. Silo
Integration backend that manages connections to GitHub, GitLab, and Slack. Handles OAuth flows, webhook processing, and API communication with external systems. Intake
Email ingestion service that converts incoming emails into work items or comments. Requires SMTP configuration and DNS setup.
Infrastructure dependencies
PostgreSQLPrimary relational database storing all application data including projects, work items, users, and configuration. Plane requires PostgreSQL 15.7+ or 16.x. Redis/Valkey
In-memory cache and session store. Used for caching frequently accessed data, storing user sessions, and managing real-time collaboration state. RabbitMQ
Message queue for asynchronous task processing. Workers pull jobs from queues for background operations like imports, exports, and notifications. MinIO/S3
Object storage for file uploads, attachments, and generated exports; can be replaced with any S3-compatible storage system. OpenSearch
Optional search indexing service for enhanced search capabilities. Not required for basic Plane functionality.
