Introduction

Automatisch lets you build automated workflows between your apps using a visual drag-and-drop editor. It runs on your own server so your data stays private and you avoid per-task pricing from hosted services.

What Automatisch Does

  • Connects apps like Slack, GitHub, Google Sheets, and dozens more through pre-built integrations
  • Provides a visual flow builder where you chain triggers and actions without code
  • Runs workflows on a schedule, on webhook trigger, or on app events
  • Stores all workflow data and execution logs on your own infrastructure
  • Supports conditional logic and data transformation between steps

Architecture Overview

Automatisch is a Node.js application with a React frontend and a PostgreSQL database. A background worker service polls for triggers and executes workflow steps. Each integration is implemented as a plugin with standardized trigger and action interfaces.

Self-Hosting & Configuration

  • Deploy with Docker Compose, which starts the web app, worker, and PostgreSQL
  • Configure SMTP settings for email notifications in the environment file
  • Set up OAuth credentials for each app integration you want to use
  • Adjust worker polling intervals and concurrency via environment variables
  • Place behind a reverse proxy for TLS and custom domain support

Key Features

  • Visual workflow editor with a clean drag-and-drop interface
  • No per-task or per-workflow pricing, unlimited automations
  • Pre-built integrations for popular services with trigger and action steps
  • Execution history with detailed logs for each workflow run
  • Role-based access control for team environments
