The published terms restrict some commercial uses, including offering functionality that substantially derives its value from n8n.

Teams that require source modification or operation of the full platform on their own infrastructure should evaluate those constraints before adopting one. - -## Enterprise requirements - -Open-source adoption often reaches a security and governance review before production. Sim's [pricing and enterprise materials](https://www.sim.ai/pricing) describe options intended for those reviews: - -- **SSO and SAML** for identity provider integration on supported enterprise deployments -- **SOC 2 Type II** and security review materials for vendor assessment -- **BYOK (bring your own key)** options for teams that want to use their own model-provider credentials -- **Access controls** for governing workspace and workflow operations -- **Programmatic administration** for teams integrating provisioning and deployment into internal processes -- **Workspace branding, import, and export** options for managed environments -- **Self-hosting choices** for organizations that need greater control over network and data boundaries - -Exact controls and deployment responsibilities should be confirmed with Sim for the selected plan.

Zapier fits business users who want managed SaaS automation and do not need source access or self-hosting. See the broader guide to the [best Zapier alternatives](https://www.sim.ai/library/best-zapier-alternatives) for additional options. -3. **Make gives operations users detailed visual control over multi-step automations.** Make's [visual platform](https://www.make.com/en/visual-platform) exposes data mappings, filters, branches, and execution routes on a scenario canvas. Make fits you if you already use its scenario-building model or need to inspect complex workflows visually. -4. **Gumloop provides a no-code builder for AI-focused automation.** Gumloop's [hosted platform](https://www.gumloop.com/) lets users assemble workflows around models and business tools without operating the supporting infrastructure. Gumloop fits you if you want to build AI agent-style automations and prefer a hosted service over self-hosting. - -## Comparison table - -The clearest dividing line is ownership: Sim and n8n support self-hosting, while Zapier, Make, and Gumloop are managed services.
