Activepieces

Best fully open-source option (MIT license means no restrictions on self-hosting or commercial use). Easier to self-host than n8n (single Docker container), cleaner UI for non-technical users, and community is active. For teams that want n8n flexibility but prefer MIT license or simpler setup, Activepieces is the pick.

Ranked eighth because it is newer and has fewer integrations than n8n (100+ vs. 400+). n8n has stronger ecosystem, more community nodes, and more deployment patterns (Kubernetes, Docker, npm). Activepieces wins on license simplicity and ease of self-hosting. For teams starting fresh with open-source automation, this competes with n8n; for teams already on n8n, migration cost is not worth it unless license matters.

GTM engineers use Activepieces the same way they use n8n: build API-based workflows (enrich leads, sync CRM to warehouse, send Slack notifications), self-host for data control, and version-control workflows in Git (via export/import). Teams choose Activepieces over n8n when MIT license is required (some enterprises ban fair-code or source-available licenses) or when Docker setup matters (Activepieces is single container, n8n is multi-container). Cloud version handles lighter workflows; self-hosted handles sensitive data.

Open-source under MIT license (no commercial restrictions). Self-hosted is single Docker container (simpler than n8n multi-container setup), or use cloud version (free tier, paid plans for team features). 100+ pre-built pieces (connectors), growing quickly but still behind n8n. Custom pieces are TypeScript code; easier to write than n8n nodes but ecosystem is smaller. Pricing for cloud version is per task (similar to Zapier model), which is less generous than n8n cloud execution-based pricing. Community is smaller but active (Discord, GitHub). For GTM teams, this is a fallback when n8n license is a blocker or when Docker simplicity matters. Most teams default to n8n unless they have specific license or deployment constraints.
