theodosia vs n8n
theodosia: Theodosia acts as a gatekeeper for Burr applications, mounting them as a FastMCP server to manage tool calls and ensure state machine transitions are valid. It significantly improves agent reliability and traceability by enforcing graph logic and logging all interactions, including structured refusals.; n8n: n8n is a secure workflow automation platform for technical teams, combining the flexibility of code with the speed of no-code. It offers 400+ integrations, native AI capabilities, and allows full control over data and deployments with its fair-code license.

When to choose:
- You want a visual workflow builder with 1,500+ integrations, 9,000+ templates, and first-class AI agent, tool-calling, and human-approval nodes.
- You want the ability to drop in custom JavaScript or Python code steps inside visual workflows and self-host via Docker.
When to skip:
- You require an OSI-approved open-source license (such as MIT or Apache-2.0); n8n uses the fair-code Sustainable Use License.
- You want code-first durable execution without a visual canvas; Temporal or AutoKitteh are built for code-first workflows.
