Keep the HTML or framework form your team already designed. Form Plume adds managed submissions, uploads, spam controls, email, and integration delivery without replacing your interface with a hosted conversational builder.
Side by side
HeyForm and Form Plume can both collect responses, but they begin on opposite sides of the form. HeyForm supplies the builder, hosted experience, logic, analytics, and embeds; Form Plume supplies the operational backend for a form you already own. Hosted HeyForm prices below are its published annually billed rates.
| Decision point | Form Plume | HeyForm |
|---|---|---|
| How forms are created | Bring your existing HTML or framework form Keep your markup, component library, validation, accessibility, and visual system exactly where they are | Conversational visual form builder Create surveys, quizzes, polls, and lead forms with templates, field types, themes, and a hosted renderer |
| Hosted pricing | 500 responses free; 10,000 for $12/month A permanent entry tier and a focused Pro plan for production form handling | $15/month for 5,000 responses Basic is billed annually after a seven-day trial; Premium is $24 for 20,000 and Business is $40 for 150,000 |
| Frontend delivery | Native form action or JavaScript request Submit directly from your page without loading a third-party form renderer | Hosted link plus four embed modes Publish as a standard inline embed, modal, corner popup, or full-page experience, including React embed support |
| Logic and respondent experience | Your frontend owns behavior Implement branching, multi-step flows, and validation in the application code your team already maintains | Built-in conditional logic and answer piping Create dynamic paths, quiz outcomes, calculations, and personalized screens inside the builder |
| Files and payments | Managed uploads included on Free Collect files securely from custom forms without adopting a hosted form canvas | Upload, signature, and Stripe payment fields Basic and Premium list 10MB uploads; Business removes the file-size limit and payment commission |
| Automation | Signed webhooks plus broad app routing Send submissions to native destinations, Zapier, Make, MindCloud, or any verified webhook target | Direct integrations, Zapier, Make, and webhooks Connect tools such as Sheets, Airtable, HubSpot, Mailchimp, Salesforce, Slack, or a JSON POST endpoint |
| Spam handling | Layered controls with recoverable quarantine Combine adaptive filtering, CAPTCHA choices, honeypots, time traps, origin rules, rate limits, and blocklists | Spam prevention and a separate spam inbox Hosted plans list spam prevention; self-hosted configuration exposes reCAPTCHA and Akismet credentials |
| Hosting and software ownership | Fully managed Form Plume cloud No database, cache, reverse proxy, upgrades, backups, or form infrastructure for your team to operate | Hosted service or AGPL-3.0 self-hosting The community edition can run with Docker, MongoDB, KeyDB or Redis, storage, and a reverse proxy you manage |
Where Form Plume pulls ahead
A conversational builder is useful when the form experience still needs to be created. When the interface already lives in your product or website, Form Plume removes a second design system and concentrates on reliable submission operations.
Replacing polished application components with an embedded builder can duplicate design, validation, analytics, and accessibility work. Form Plume lets the existing interface stay authoritative and adds only the missing backend services.
A builder introduces templates, themes, question models, publish settings, embed scripts, and another place to manage changes. A Form Plume endpoint keeps authoring in the repository while centralizing submissions, files, delivery, and spam review.
HeyForm's active AGPL project is a real advantage for teams prepared to self-host. Form Plume is the better fit when the goal is to avoid owning MongoDB, Redis-compatible caching, storage, SMTP, TLS termination, updates, and incident response.

FAQ
HeyForm is a conversational form builder that creates and publishes the respondent interface. Form Plume is a managed backend for HTML and framework forms you already designed. Choose HeyForm when you need a visual builder; choose Form Plume when you want to preserve your frontend and add submission infrastructure.
Form Plume has a permanent Free plan with 500 monthly submissions and offers 10,000 on Pro for $12 per month. HeyForm lists Basic at $15 per month billed annually for 5,000 responses after a seven-day trial. HeyForm's higher plans provide much larger response limits and builder-specific features, so compare scope as well as volume.
Not as a one-click builder import. HeyForm owns the rendered questions, logic, themes, and embed behavior, while Form Plume receives a form you host. Recreate the necessary fields in your site's HTML or components, point the form action at a Form Plume endpoint, and test files, validation, notifications, and integrations before switching traffic.
No. Form Plume deliberately works behind the form interface rather than replacing it. HeyForm is the better product when teammates need templates and a visual canvas to create surveys or quizzes. Form Plume is better when designers and developers already control the markup and want the backend handled for them.
Yes. HeyForm publishes an AGPL-3.0 community edition and Docker instructions using a Node service, MongoDB, KeyDB or Redis, persistent uploads, and a reverse proxy for HTTPS. That is a genuine advantage for teams that require source and infrastructure control. Form Plume is a managed cloud service and does not promise a self-hosted edition.
HeyForm is more complete out of the box. Its builder includes conditional logic, answer piping, calculations, quiz outcomes, and custom ending screens. With Form Plume, those interactions remain frontend code, which provides full control but expects your team to implement the experience in its own application.
Both support uploaded files. HeyForm lists file collection across hosted plans, with a 10MB upload figure on Basic and Premium and no size limit on Business. Form Plume includes managed file uploads on Free for forms you host, making it convenient when the existing website needs an upload backend rather than a new form builder.
Yes. HeyForm documents JSON webhooks and integrations including Zapier, Sheets, Airtable, HubSpot, Mailchimp, Salesforce, and Slack. Form Plume combines native destinations with signed webhooks, Zapier, Make, MindCloud, and broader app routing. Form Plume is the stronger fit when verified delivery from an existing custom form is the priority.
HeyForm lists spam prevention, separates suspected responses into a spam inbox, and exposes reCAPTCHA and Akismet configuration for self-hosters. Form Plume uses a layered system with adaptive filtering, several CAPTCHA choices, honeypots, time traps, origin controls, rate limits, email hygiene, blocklists, and a recoverable quarantine for public forms.
Choose HeyForm when you want non-developers to build conversational surveys, quizzes, polls, payment forms, and branded embeds, or when an AGPL self-hosted builder is a firm requirement. Choose Form Plume when the frontend already exists and you want a smaller managed surface for submissions, uploads, notifications, spam protection, and integrations.
One line. Zero backend.
