Start with 500 monthly submissions, 60-day history, file uploads, and a signed webhook on Free. Form Plume removes the early feature gates that FormWit places between a basic inbox and an automated form workflow.
Side by side
FormWit and Form Plume both connect custom HTML or JavaScript forms to a hosted inbox. This comparison focuses on the limits that change how soon a form needs an upgrade and what each backend can do at that point.
| Decision point | Form Plume | FormWit |
|---|---|---|
| Free submission allowance | 500 / month Five times the monthly runway before an upgrade | 100 / month Excess submissions are held for 48 hours |
| Forms | Unlimited Included across the published plans | Unlimited Included on Free, Starter, and Pro |
| Free submission history | 60 days Useful for revisiting leads after a campaign | 7 days Unlimited retention begins on Starter |
| First paid plan | $12 monthly or $108 yearly 10,000 submissions with monthly billing available | $39 / year 10,000 submissions; annual billing only |
| File uploads | Included on Free 100 MB of storage before upgrading | Starter and Pro 1 MB files on Starter and 5 MB files on Pro |
| Webhook delivery | 1 signed webhook on Free Unlimited signed destinations on Pro | Starter and Pro Optional HMAC signature and three automatic retries |
| Spam controls | Layered filtering with recoverable quarantine Honeypot, rate limits, domain controls, four CAPTCHA choices, blocklists, and adaptive scoring | Honeypot, rate limiting, and keyword filters Official material emphasizes a CAPTCHA-free experience |
| Routing and data access | Native integrations plus broad automation Zapier, Make, MindCloud, signed webhooks, CSV export, and API access | Email, dashboard, CSV, and webhooks Search, export, and webhook routing require Starter or Pro |
Where Form Plume pulls ahead
FormWit keeps annual pricing unusually low. Form Plume puts more of the operational stack on Free, so teams can test real traffic, attachments, and downstream delivery before paying.
FormWit stores Free-plan submissions for seven days and accepts 100 each month. Form Plume keeps them for 60 days and accepts 500, giving teams time to qualify leads, compare campaign periods, and catch up after time away.
FormWit reserves uploads and webhooks for Starter and Pro. Form Plume includes file storage and one signed webhook on Free, so an application, support request, or automation prototype can be validated end to end first.
FormWit's honeypot, keyword filtering, and automatic rate limits favor a quiet CAPTCHA-free setup. Form Plume adds selectable CAPTCHA providers, domain restrictions, blocklists, email hygiene, adaptive scoring, and recoverable quarantine for more control under sustained abuse.
Choose by situation
Side project with very predictable traffic
It depends
FormWit's $39 annual Starter tier is inexpensive; Form Plume's larger Free plan may avoid billing entirely while the audience develops.
Application or support form with attachments
Form Plume
Free file storage lets the complete workflow launch before upload volume justifies a paid plan.
Agency wanting 100,000 monthly submissions
FormWit
Its published Pro plan offers that allowance for $149 per year when raw volume and low annual cost outweigh richer routing controls.
Public form feeding several business tools
Form Plume
Native destinations, multiple automation ecosystems, signed delivery, and layered abuse controls provide more routes and safeguards.
FAQ
Form Plume gives a new form five times more monthly submissions, 60-day rather than seven-day history, file storage, and a signed webhook without charging. That combination is useful when the form needs to prove a complete production workflow before the first upgrade.
Yes at the first paid tier. FormWit Starter costs $39 per year for 10,000 monthly submissions, while Form Plume Pro is $12 per month or $9 per month billed yearly for the same submission allowance. Form Plume includes more on Free and offers monthly billing; FormWit wins when annual price is the primary criterion.
Usually. Both products receive ordinary HTML posts and JavaScript requests. Create a Form Plume endpoint, replace the action URL, test the success behavior, then confirm notifications and any file or webhook deliveries before retiring the FormWit endpoint.
Form Plume Free is more complete for a working website. It includes 500 submissions, 60-day retention, 100 MB of file storage, and one signed webhook. FormWit Free includes 100 submissions, seven-day retention, one email recipient, spam filtering, and a dashboard, but not uploads or webhooks.
Yes. Both publish unlimited forms on their free and paid plans, making either service workable for a collection of small sites. The larger difference is how many submissions each endpoint collection can receive and which operational features are available before payment.
FormWit enables attachments on paid plans, with a 1 MB file limit on Starter and 5 MB on Pro. Form Plume starts with 100 MB of aggregate file storage on Free and expands storage on its paid tiers, making it easier to test an attachment-dependent form at no cost.
They can be. FormWit documents an optional HMAC secret, an X-Formwit-Signature header, and up to three retries for paid-plan webhooks. Form Plume includes one signed destination on Free and unlimited signed webhooks on Pro, so authenticated delivery can be part of the initial build.
FormWit automatically applies rate limiting and keyword filters and supports a honeypot field without showing visitors a CAPTCHA. Form Plume supports that low-friction foundation while adding Turnstile, hCaptcha, reCAPTCHA v2 and v3, domain controls, manual blocklists, adaptive filtering, and a recoverable spam inbox.
Yes, indirectly through a paid-plan webhook. FormWit names Zapier, Make, Google Sheets, and other webhook-compatible tools. Form Plume combines signed custom webhooks with native integrations and dedicated routes into Zapier, Make, and MindCloud for broader automation choices.
Choose FormWit when you are comfortable paying annually, need 10,000 submissions at the lowest published annual price, and its email, dashboard, CSV, and webhook workflow covers the job. Choose Form Plume when free runway, uploads, retention, integration breadth, or advanced spam controls matter more.
One line. Zero backend.
