Keep the form your team already built. Form Plume adds a live free endpoint, uploads, signed automation, layered spam controls, and an operational inbox without turning your frontend into a builder project.
Side by side
Reform and Form Plume overlap in headless form handling, but start from different assumptions. Reform leads with a conversion-oriented builder; Form Plume leads with an endpoint for your existing HTML. Prices below are monthly list prices.
| Decision point | Form Plume | Reform |
|---|---|---|
| Live free forms | 500 submissions / month Publish a real form with no card and no monthly charge. | Builder access only Reform Free forms cannot be published, shared, or used live. |
| First paid plan | $12 / month 10,000 submissions with backend workflow features | $15 / month Basic includes unlimited responses and live publishing. |
| Using your own HTML | Direct standard form endpoint Point your existing action at Form Plume without recreating fields. | Headless mapping on paid plans Inputs map to Reform block IDs; some integrations and custom code are incompatible. |
| File uploads | Included on Free 100 MB of storage for custom HTML forms | Pro only ($35 / month) The file-upload block is not supported in headless mode. |
| Signed webhooks | 1 on Free Unlimited on Pro with delivery visibility | Pro only ($35 / month) Multiple endpoints can verify payloads with an HMAC signature. |
| Form-building experience | Bring your existing frontend Best when you already control the HTML, styling, and interaction. | Conversion-focused visual builder Hosted and iframe forms, multi-step flows, logic, partial responses, and custom code. |
| Integration reach | Native routes plus three automation ecosystems Zapier, Make, MindCloud, and arbitrary signed webhook destinations. | Basic and Pro integration tiers Basic lists Sheets, Notion, and Zapier; CRM connections and webhooks require Pro. |
| Spam protection | Layered filtering with recoverable quarantine Four CAPTCHA choices, domain controls, rate limits, blocklists, and adaptive scoring. | reCAPTCHA on Basic and Pro A configured Google reCAPTCHA blocks submissions that fail its check. |
Where Form Plume pulls ahead
Reform is thoughtfully designed for teams creating lead funnels inside its editor. Form Plume removes extra mapping and paid-tier gates when your site already supplies the fields, layout, and experience.
Reform Free is a workspace for building and testing, but its forms cannot be published or shared publicly. Form Plume Free handles 500 live submissions per month, so a small production site can launch before choosing a subscription.
Reform headless forms require each HTML input to reference a matching builder block ID. They also exclude file uploads and are incompatible with some integrations and custom-code features. Form Plume accepts the fields already present in a normal HTML form.
Reform reserves file uploads and signed webhooks for its $35 Pro plan. Form Plume puts both on Free, alongside layered filtering and a recoverable spam inbox, then expands capacity and automation on its $12 Pro plan.

FAQ
Form Plume is a strong Reform alternative when your form is already built. Change the form action to a Form Plume endpoint and keep your current names, markup, validation, and styling. Reform's headless mode instead maps inputs to block IDs created in its builder.
No. Reform says its Free plan lets you build and test workflows, but forms cannot be published, shared, or used live. Form Plume Free is production-ready for up to 500 submissions each month.
Form Plume can be used live for free and Pro costs $12 per month. Reform requires its $15 Basic plan to publish a live form and $35 Pro for uploads, webhooks, conditional logic, team access, partial responses, and custom code. Reform does include unlimited responses on both paid plans, which can matter at high volume.
Yes. Reform Basic and Pro include a headless option for using your own HTML. Each input must reference a corresponding Reform block ID, and its documentation notes that headless forms do not support file-upload blocks and are incompatible with certain integrations and custom-code features.
Reform has the advantage when marketers want to build the complete lead experience without code. Its Pro plan includes conditional paths, partial submissions, save-and-return, team collaboration, custom CSS and JavaScript, and CRM integrations. Form Plume is better when your website or application already owns that experience and only needs the form backend.
Yes. Reform signs webhook payloads with a per-webhook HMAC secret, but webhooks require its $35 Pro plan. Form Plume includes one signed webhook on Free and ten on Pro, making authenticated event delivery available earlier.
No. Reform's file-upload block is a Pro feature, and its headless guide explicitly says file uploads are unsupported in headless mode. Form Plume accepts uploads from custom HTML forms on Free and stores them outside email attachments.
Reform includes Google reCAPTCHA on its paid plans. Form Plume combines reCAPTCHA v2 and v3, Turnstile, and hCaptcha with honeypots, time traps, adaptive scoring, rate limits, domain controls, blocklists, email hygiene, and a recoverable quarantine.
Reform offers useful basic destinations such as Google Sheets, Notion, and Zapier, with webhooks and CRM connections in Pro. Form Plume combines native integrations with Zapier, Make, MindCloud, and any signed webhook target, making it the broader routing layer for custom forms.
Keep Reform when its builder, unlimited paid responses, multi-step logic, incomplete-submission visibility, enrichment, or direct CRM workflow is central to how your team improves conversion. Choose Form Plume when preserving your existing frontend, launching free, or unlocking uploads and signed automation at a lower tier matters more.
One line. Zero backend.
