Five developer licenses are $2,640 a year. ## ToolGPA grades **GPA: 1.6 out of 4**, graded Nov 13, 2026. Form.io builds forms from JSON and serves them through an API, either hosted on its portal or in Docker containers you run yourself. It is priced by project and environment rather than by usage, which puts it far above ordinary form builders. - **Value for money: D.** The hosted project is $300 a month and self-hosting starts at $660, against a forms middle of $20 and a dearest tenth from $66. - **Free plan and trial: C.** A 30-day trial needs no card, but the project turns read-only afterward and it may not hold personal data. - **Features: C.** Forms, API and PDF output are covered, but reporting, accessibility, multi-tenancy and the embedded builder are paid add-ons. - **Ease of use: D.** It is built for developers: JSON definitions, and Docker containers and databases for the self-hosted route. - **Platforms and integrations: C.** Web only, with an API and an open-source JavaScript library, and no integrations list on record.

What Form.io does at its core is forms, and that is the kind of thing an AI app builder makes well. You would give up one thing, listed below, and little else. It costs $3,600 a year. An AI app builder starts at about $20 a month on our listings, and you only need it while you build. Form.io is open source, so there is a third way: take its code and run it yourself. - You could make: Forms: an app builder makes this well. - You could make: It runs in a browser, which is where something home-made would run too. - You could not: An API that other software can build on.
