Handle 500 monthly submissions, retain them for 60 days, accept files, and verify a signed webhook on Free. When the form becomes a business workflow, move to 10,000 submissions across unlimited forms for $12 per month.
Side by side
FormKeep prices capacity partly through the number of forms included: one on Essential, three on Professional, and ten on Premium. This comparison looks beyond the cheapest sticker price to the submission room, storage, retention, automation, and collaboration a working collection of forms actually receives.
| Decision point | Form Plume | FormKeep |
|---|---|---|
| Free submission runway | 500 / month Ten times the allowance for launches and real website traffic | 50 / month Spam counts toward the cap, and submissions beyond it are lost |
| Free data retention | 60 days Two months to review, export, or recover an inquiry | 1 month Permanent retention is listed only on the Premium tier |
| First paid plan | $12 / month 10,000 submissions across unlimited forms | $4.99 / month Essential includes 1,000 submissions and one form |
| File uploads | 100 MB on Free 10 GB is included on Pro | Begin on Essential 10 MB per attachment; FAQ lists 2 GB on Essential and 5 GB on Professional |
| Webhook automation | Signed webhook on Free Unlimited cryptographically signed destinations on Pro | Available on Essential Official documentation describes real-time reposting but not payload signatures |
| Integration routes | Native apps plus open-ended automation Zapier, Make, MindCloud, and arbitrary signed webhook targets | 30 documented direct apps plus Zapier The built-in catalog is reserved for Professional and higher |
| Spam and CAPTCHA controls | Layered defenses with four CAPTCHA options Adaptive filtering, domain controls, rate limits, blocklists, email hygiene, and quarantine | Learned filtering, rules, honey fields, and reCAPTCHA The FAQ says hCaptcha is not supported and all spam consumes the monthly limit |
| Teams and shared ownership | $39 / month 10 members, unlimited forms, and lifetime retention | $59 / month Premium Team members, 10 forms, and permanent retention |
Where Form Plume pulls ahead
FormKeep can be economical for a single low-volume endpoint and offers a strong direct-app catalog. Form Plume becomes more compelling when several forms share meaningful traffic or automation must be secure from the beginning.
FormKeep Free accepts 50 submissions, counts spam toward that limit, and says over-limit submissions are lost. Form Plume starts at 500 and places suspicious messages in a recoverable quarantine, creating a safer runway for a launch or public contact form.
FormKeep's paid packages include one, three, or ten forms. Form Plume keeps forms unlimited on Free, Pro, and Team, so an agency, product suite, or campaign calendar can separate endpoints without using form count as a budgeting constraint.
FormKeep puts webhooks on Essential and documents reposting accepted data to a URL. Form Plume includes one signed webhook on Free and unlimited signed delivery on Pro, letting the receiver authenticate payloads before triggering downstream work.
Choose by situation
Single quiet form with a strict budget
FormKeep
Essential costs less when one endpoint, 1,000 monthly submissions, and its included feature set are all you need.
Agency portfolio or multi-site business
Form Plume
Unlimited forms at every tier avoid mapping each new client, campaign, or department to another included-form slot.
Workflow requiring a particular direct connector
It depends
FormKeep documents 30 built-in apps; Form Plume offers native destinations and broader routes through Zapier, Make, MindCloud, and signed webhooks.
Public form with unpredictable traffic and spam
Form Plume
Ten times the free allowance, more CAPTCHA choices, layered controls, and recoverable quarantine reduce the risk of losing legitimate messages.
FAQ
Choose Form Plume when your account needs several endpoints, more than 50 free submissions, uploads before paying, or a signed webhook. Its plans are designed around total workload rather than a small number of included forms.
FormKeep Essential has the lower entry price at $4.99 per month, but it includes one form and 1,000 submissions. Form Plume Pro costs $12 for unlimited forms and 10,000 submissions, so it offers stronger value once traffic or endpoint count matters.
In most cases, yes. FormKeep and Form Plume both receive ordinary HTML posts. Create the replacement endpoint, change the form action, confirm field names and redirects, then test notifications, uploads, CAPTCHA, and automations before removing the old destination.
Both allow unlimited forms, but their operating room differs. FormKeep lists 50 monthly submissions, daily notifications, and one month of retention. Form Plume includes 500 submissions, 60-day retention, 100 MB of upload storage, and one signed webhook.
Form Plume includes file uploads and 100 MB of storage on Free. FormKeep lists file attachments on Essential, caps each attachment at 10 MB, and reports 2 GB of storage on Essential and 5 GB on Professional.
FormKeep's official integration documentation says it reposts non-spam submissions to a configured URL in real time, but it does not document a payload signature. Form Plume signs deliveries so your receiver can verify their origin before processing them.
FormKeep has a substantial catalog of 30 named direct apps on Professional and higher, plus Zapier and custom webhooks. Form Plume combines native destinations with Zapier, Make, MindCloud, and arbitrary signed webhooks. The better choice depends on whether one direct connector or flexible automation breadth matters more.
FormKeep combines learned spam detection, manual feedback, field rules, honey fields, unique-value checks, and reCAPTCHA. Form Plume adds multiple CAPTCHA providers, rate limits, domain controls, blocklists, email hygiene, adaptive scoring, and a quarantine where legitimate messages can be recovered.
Yes. FormKeep documents CSV reports and a token-authenticated JSON endpoint for paginated submission retrieval. Form Plume Pro includes CSV export and API access alongside integrations and signed webhook delivery for event-driven workflows.
Keep FormKeep when its builder, mature direct connector catalog, server-side field rules, or $4.99 single-form Essential plan already matches your workflow. Consider Form Plume when free capacity, unlimited paid forms, signed automation, CAPTCHA choice, or lower-cost team ownership resolves a real constraint.
One line. Zero backend.
