Different problems, different tools
Formbricks is an open-source survey platform. It lives inside your app. You target users by behavior, trigger surveys at specific moments, and analyze NPS and CSAT scores. It is good at that.
Sutrena is the web runtime for AI agents. You send JSON to an API and get a hosted form back. You collect submissions, build dashboards, and AI agents can do the whole thing through 44 MCP tools. No in-app widget, no user targeting. If you are choosing between them, the question is probably what problem you are solving.
For AI agents, Sutrena has 44 MCP tools and a full REST API. Formbricks was built for humans doing user research — no programmatic API for agents to create surveys, focused on in-product feedback flows.

Sutrena is the web runtime for AI agents. Three primitives — pages, forms, and dashboards — accessible through one API. Your agent creates web artifacts, humans interact with them, and your agent gets the data back. Framework-agnostic. Works from any MCP client or HTTP client.
