Fillout vs Tally for AI agents

FilloutL4Runs on its own

Through every checkpoint. Next: pay without a person

L4 · Runs on its own: our agent got in on its own and worked the API without getting stuck on any checkpoint. Signup, email verification and the key page in Settings > Developer all passed, and an invisible reCAPTCHA let our agent's browser through. Through the API it listed forms and created, searched and deleted submissions on its own; building the forms themselves (fields, logic, calculations, publish) still needs the web builder, since the MCP server has no form tools. Upgrading runs through an embedded Stripe card form, and deleting the organization removed the forms, database and submissions in one step, after which the key and MCP token were rejected.

TallyL4Runs on its own

Through every checkpoint. Next: pay without a person

L4 · Runs on its own: once signed up, Tally gets in on its own and does the work. Sign-up, email verification and the API key page need a browser; there is no documented sign-up API, and our agent found no bot check to pass. From there, the REST API and the official MCP server let it create, edit, publish and clean up forms headless, with no further stop. Paying and account deletion both happen on the web: the upgrade goes through Stripe Checkout, with an option to flag the buyer as an agent, and deleting the account removes it at once.
