Sutrena vs Web3Forms

Form-to-email vs form platform

Web3Forms is about as simple as form handling gets. Add an access key to your HTML form, and submissions go straight to your email. No accounts, no databases. For a contact form on a portfolio site, it is honestly great.

Sutrena is the web runtime for AI agents. It creates forms via API, stores every submission, builds dashboards, and gives AI agents 44 MCP tools to manage everything. More complex, more expensive. The question is whether you need email delivery or a programmable form platform.

For AI agents, Sutrena has 44 MCP tools and a full REST API. Web3Forms was built for humans clicking buttons — no programmatic API for agents to create forms, no dashboards, no data storage.

What is Sutrena?

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.

Get started in two API calls

1. Get a trial key (no auth, no signup)

curl -X POST https://sutrena.com/api/trial

2. Create a form + dashboard from a template

curl -X POST https://sutrena.com/api/forms \
  -H "Authorization: Bearer st_trial_xxx" \
  -H "Content-Type: application/json" \
  -d '{"templateId": "waitlist", "createDashboard": true}'
/llms.txt/api/schema/llms-full.txt/.well-known/mcp.json

Want to try it?

Grab a trial API key. No signup, no credit card. Point your agent at it and see what happens.
