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 an API-first platform for pages, forms, analytics, and automations. It creates forms via API, stores every submission, provides privacy-first analytics, and gives AI agents 67 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 67 MCP tools and a full REST API. Web3Forms was built for humans clicking buttons — no programmatic API for agents to create forms, no analytics, no data storage.
