Best for engineering teams embedding forms in their own apps
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.
Who Form.io is for
- Fits if your developers need forms inside your own application and its data
- Makes sense if you must host data in your own infrastructure
Who Form.io is not for
- Skip it if you want a free plan, because none exists
- Pricey if you only need a few forms: the lowest hosted plan is $300 a month
- Tight if you need several environments, since each needs its own server license
- Watch out: the hosted project may not collect personal or sensitive data
- Not for you if you want a no-code builder without developers
Why Form.io gets a 1.6
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- DValue for moneyThe hosted project is $300 a month and self-hosting starts at $660, against a forms middle of $20 and a dearest tenth from $66.
- CFree plan and trialA 30-day trial needs no card, but the project turns read-only afterward and it may not hold personal data.
- CFeaturesForms, API and PDF output are covered, but reporting, accessibility, multi-tenancy and the embedded builder are paid add-ons.
- DEase of useIt is built for developers: JSON definitions, and Docker containers and databases for the self-hosted route.
- CPlatforms and integrationsWeb only, with an API and an open-source JavaScript library, and no integrations list on record.

Keep Form.io, or make your own?
You could make this
A form at its plainest is questions, a button and a table of answers.
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.
What you could make
- Forms: an app builder makes this well.
- It runs in a browser, which is where something home-made would run too.
What you could not
- An API that other software can build on.
What this rests on. Form.io’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is Form.io?
Form.io is a platform for building forms and the APIs behind them, driven by JSON form definitions. It is sold as Docker containers that a customer runs in its own environments and databases, plus a hosted SaaS project on portal.form.io. Pricing is by project and environment, not by submissions or users.
Worth knowing
- There is no free plan; the hosted SaaS project is $300 a month after the 30-day trial, and the self-hosted options start higher.
- Self-hosted minimum is one project plus one API server environment, $660 a month; each extra environment needs its own server license.
- The SaaS project must not hold personal or sensitive data, per the pricing page, and lacks some security features.
- Add-ons per month: Reporting UI $660, accessibility $495, multi-tenancy $330, embedded builder $660. Five developer licenses are $2,640 a year.
Key features
- JSON-driven forms
- Forms are defined in JSON, rendered by the open-source formio.js library and stored through the platform's API.
- Self-hosted containers
- The platform ships as Docker containers that run in the customer's own environments and databases.
- PDF forms
- Optional PDF servers display PDF forms and export submissions to PDF.
- Multi-tenancy and embedded builder
- Paid add-ons support tenant-separated forms and data, and an embedded form builder inside your own application.
- Security options
- API Plus adds audit logging, field-level encryption and data separation for compliance needs.
