n8n

TAS Score: S3/3 — D4/5 — A3 / T1 D4 not D5: “Sustainable Use License” is source-available but not OSI-approved — commercial use restricted without paid license (Q7, Q8). Self-hosting for personal/internal use is free.

Brief Description

Source-available workflow automation platform. Visual node-based editor with 400+ integrations. Selfhosted or cloud. Supports code nodes (JavaScript/Python) for custom logic. 106,000+ GitHub stars. Licensed under Sustainable Use License (free for personal and internal use).

Architectural Role

Integration/automation layer: connects services, automates workflows, API orchestration. Direct alternative to Zapier with selfhosted option.

Technical Autonomy

Works without internet — workflows execute locally; external integrations require internet
Stores data locally — SQLite or PostgreSQL, all on your server
Does not require external accounts
Allows data export — workflows exportable as JSON; fully portable between n8n instances
Provides offline updates — Docker image, updated manually

Philosophical Assessment (whose.world criteria)

Criterion	Status	Comments
Pause	✅	Stop the container. Workflows pause. Resume without loss.
Exit	✅	Workflows export as JSON. Credentials stored locally. Database is standard SQLite/PostgreSQL.
Recoverability	✅	Database backup + workflow JSON export. Straightforward restore.
Visibility	✅	Source code fully available on GitHub. Audit possible.
External Dependencies	✅	Requires only Node.js runtime. Optional: PostgreSQL. No mandatory external services.

Rating key: ✅ fully meets · ⚠️ partially meets or requires configuration · ❌ does not meet

Configuration (Minimal)

services:
  n8n:
    image: n8nio/n8n:latest
    environment:
      - N8N_BASIC_AUTH_ACTIVE=true
      - N8N_BASIC_AUTH_USER=admin
      - N8N_BASIC_AUTH_PASSWORD=changeme
    ports:
      - 5678:5678
    volumes:
      - ./n8n_data:/home/node/.n8n
    restart: unless-stopped

Runs on ~256 MB RAM for basic workflows. PostgreSQL recommended for production.

Developer Workstation

Alternatives

Alternative	Autonomy	Notes
Node-RED	A3 / T2	Apache-2.0, lighter, IoT-focused, fewer SaaS integrations
Zapier	A0 / T0	No-code, 7000+ apps, fully proprietary, no export

Trajectory

Direction: mixed

n8n changed from Apache-2.0 to Sustainable Use License in 2022 — a significant closing signal. However: source remains fully available, selfhosting for personal/internal use is free, and development is very active (106K+ stars, regular releases). The company offers n8n Cloud as paid SaaS. Commercial selfhosting requires paid license. The license change is worth noting but hasn’t affected the selfhosted experience for most users.

Signal assessment:

Signal	Status	Evidence
License	⚠️	Changed from Apache-2.0 to Sustainable Use License (2022). Source-available but not OSI-approved.
Feature gating	➖	All features available in selfhosted. Cloud version is paid alternative, not gated features.
Self-hosting	✅	Selfhosting is fully supported and documented. Primary deployment model for community.
Governance	➖	VC-backed company (n8n GmbH, Berlin). Active community. License change was controversial but stable since.

Signal key: ✅ opening · ➖ neutral · ⚠️ closing
