Collect 500 submissions every month with uploads and a signed webhook on Free, then scale to 10,000 monthly submissions for $12. Form Plume gives busy custom forms predictable recurring capacity instead of drawing down a lifetime credit balance.
Side by side
These products price the same job in fundamentally different ways. Form-Data sells non-expiring credits for valid submissions and optional workspace add-ons; Form Plume renews a monthly allowance and bundles more operational capacity into Free and Pro.
| Decision point | Form Plume | Form-Data |
|---|---|---|
| Free usage model | 500 submissions every month Unlimited forms with the allowance renewing monthly | 100 lifetime credits One valid submission uses one non-expiring credit; forms are unlimited. |
| Paid submission capacity | 10,000 / month for $12 / month A recurring production allowance with unlimited forms. | $9.50 per 1,000 lifetime credits No recurring subscription; larger credit bundles can receive discounts. |
| Submission retention | 60 days on Free · 2 years on Pro Pro retains a complete two-year working history. | Up to 3 months included Extended retention is sold as a workspace add-on. |
| File uploads | Included on Free 100 MB on Free and 10 GB on Pro | $4 per workspace each month The upload add-on includes 1 GB; its widget defaults to 10 MB per file. |
| Webhook automation | 1 signed webhook on Free Pro includes unlimited signed webhooks and API access. | Signed and transformable webhooks Add headers or parameters and reshape JSON with JSONata. |
| Integration reach | Native destinations plus automation ecosystems Slack, Discord, Sheets, ActiveCampaign, Mailchimp, Zapier, Make, MindCloud, and signed webhooks | Zapier and webhooks Official examples include Sheets, Airtable, Slack, HubSpot, Trello, and more through those routes. |
| Spam protection | Layered controls with recoverable quarantine Four CAPTCHA choices, honeypots, domain controls, rate limits, blocklists, adaptive scoring, and email hygiene | Automatic filtering without credit charges Six-layer protection, honeypots, referrer checks, country and content filters. |
| Form creation workflow | Bring your own HTML or framework UI Keep the frontend in your design system and connect it to a focused backend. | AI Studio, hosted embeds, and forms as code Generate from text, deploy .fd files with a CLI, or connect an existing custom form. |
Where Form Plume pulls ahead
Lifetime credits are elegant for occasional traffic. When submissions arrive every week, Form Plume combines renewable capacity, file storage, longer paid retention, and signed delivery in a simpler production bundle.
Form-Data's free credits remain available until used, which suits a quiet project but provides a fixed lifetime pool. Form Plume refreshes 500 submissions every month, giving an active contact form room to keep operating without repeatedly topping up credits.
Form-Data sells file upload capacity as a $4 monthly add-on for each workspace. Form Plume includes 100 MB on Free and 10 GB on Pro, so applications, briefs, and support attachments can be part of the initial workflow.
Form-Data combines Zapier with capable signed webhooks. Form Plume adds native business destinations, Make, MindCloud, Zapier, and arbitrary signed webhook targets, giving teams more ways to route submissions without centering every workflow on one connector.

FAQ
Choose Form Plume when your custom forms receive submissions continuously and you want the allowance to renew each month. Free includes 500 monthly submissions, uploads, 60-day history, and one signed webhook; Pro combines 10,000 submissions, 10 GB of files, two-year retention, API access, and broader integrations.
Form-Data gives each account 100 free lifetime credits and charges from $9.50 for another 1,000. One valid submission consumes one credit, credits do not expire, and detected spam does not count. That model can be excellent for sporadic traffic; Form Plume's renewable monthly plans fit consistently active forms better.
Yes for a normal custom HTML or JavaScript form. Create a Form Plume endpoint, replace the form action URL or fetch destination, then test redirects, notification emails, spam handling, files, and downstream automation before retiring the previous handler.
Form Plume does. Its Free plan includes 100 MB of storage and Pro includes 10 GB. Form-Data currently prices uploads as a $4-per-workspace monthly add-on with 1 GB, although its polished upload widget offers controls for file size, count, type, camera capture, and retention.
Yes if you need Form-Data's AI Studio or hosted frontend. It can generate forms from text, publish standalone pages, embed forms in several modes, and deploy .fd definitions through a CLI. Form Plume is a focused backend for teams that prefer to own the visible form in HTML, React, or another framework.
Both can authenticate webhook deliveries. Form Plume includes one signed destination on Free and unlimited signed webhooks on Pro. Form-Data's webhooks are particularly flexible: they can add headers or body parameters and transform payloads with JSONata before delivery.
Form Plume offers the broader mix of direct and ecosystem routes, including native destinations, Zapier, Make, MindCloud, and signed webhooks. Form-Data connects through Zapier and webhooks, with official examples spanning Google Sheets, Airtable, Mailchimp, Slack, HubSpot, Trello, Zendesk, Monday, and Pipedrive.
Both provide serious automatic filtering. Form-Data advertises six layers and supports honeypots, field-aware detection, referrer validation, plus country and content rules without charging credits for spam. Form Plume adds four CAPTCHA choices, rate limits, domain controls, blocklists, email hygiene, adaptive scoring, and a recoverable quarantine for reviewing uncertain submissions.
Form-Data is the better fit when submissions are infrequent enough that non-expiring credits minimize cost, when its AI Studio replaces the need to build a frontend, or when JSONata webhook transformation removes custom middleware. Form Plume is better suited to recurring volume, included uploads, longer paid retention, and multi-route automation.
