Start with 500 monthly submissions, file uploads, and a signed webhook without paying. Form Plume bundles the production essentials earlier, then gives growing forms 10,000 monthly submissions and two years of history on Pro.
Side by side
ServerForm and Form Plume both accept standard browser posts and framework requests. The practical difference is packaging: ServerForm offers a lower first paid price and extra frontend analytics, while Form Plume puts more volume, storage, retention, and signed delivery into its core plans.

Where Form Plume pulls ahead
ServerForm covers the endpoint basics well. Form Plume pulls ahead when the same project needs attachments, authenticated delivery, more free traffic, and a longer searchable record without an immediate upgrade.
ServerForm's free allowance stops at 100 submissions in a rolling 30-day window. Form Plume provides 500 every month, so portfolios, launch pages, and early products have five times the breathing room before billing becomes a concern.
ServerForm reserves attachments and HMAC-signed webhooks for Pro. Form Plume includes 100 MB of file storage and one signed webhook on Free, making applications, support requests, and lead routing production-capable from the first plan.
ServerForm publishes 30-day Free retention and one year on Pro. Form Plume keeps Free submissions for 60 days and Pro submissions for two years, giving teams more time to audit conversations, exports, and delivery history.

FAQ
Choose Form Plume when included capacity matters more than ServerForm's hosted-page and analytics extras. Form Plume Free provides 500 monthly submissions, 100 MB of file storage, 60-day retention, and one signed webhook; Pro expands that package to 10,000 submissions, 10 GB, two-year retention, API access, and unlimited signed webhooks.
ServerForm has the lower first paid price at $9 per month for 3,000 submissions. Form Plume Pro costs $12 monthly but includes 10,000 submissions, 10 GB of files, two-year retention, and unlimited signed webhooks, so it offers substantially more capacity for the additional three dollars. Form Plume Free also includes features ServerForm places on Pro.
Usually. Both services accept ordinary HTML form posts and JavaScript requests. Create a Form Plume endpoint, replace ServerForm's action URL and access key, then test the success state, notification routing, attachments, spam behavior, and integrations before removing the old endpoint.
Form Plume Free handles 500 submissions each month, five times ServerForm's published allowance of 100. Both permit unlimited forms and include an inbox plus email notifications, but Form Plume also provides twice the retention, file storage, and one authenticated webhook destination on Free.
Yes. Form Plume includes 100 MB on Free and 10 GB on Pro. ServerForm starts attachments on its $9 Pro plan and publishes a 10 MB per-file limit there, although its feature copy also describes configurable limits from 1 to 25 MB. Confirm the applicable ServerForm limit for your account before migrating a large-file workflow.
Both cover the major CAPTCHA providers, honeypots, domain restrictions, blocklists, and scoring. ServerForm documents hCaptcha, reCAPTCHA v2 and v3, Turnstile, keyword and link rules, plus a dashboard spam score. Form Plume adds time traps, rate limits, email hygiene, adaptive filtering, and a recoverable quarantine for reviewing uncertain submissions.
ServerForm lists 12 destinations, including direct Slack, Discord, Telegram, Sheets, Teams, Notion, Airtable, and HubSpot routes alongside Zapier, n8n, and signed webhooks. Form Plume combines native integrations with Zapier, Make, MindCloud, and arbitrary signed webhook targets, making it the broader choice when long-tail app connectivity matters.
ServerForm publishes hosted shareable forms, QR codes, per-form brand kits, and analytics for field fill rates, referrer sources, weekly trends, and spam catch rates. Those are meaningful advantages when the backend must also provide a ready-made form page or client-facing reporting. Form Plume is optimized for teams keeping the frontend in their own website or application.
ServerForm says hosted submissions use EU data residency and row-level-secured Postgres. Its privacy policy describes TLS, access controls, monitoring, deletion requests, portability rights, and third-party infrastructure, payment, analytics, email, and support providers. The public pricing table defines plan retention, but the policy itself does not identify every processor or publish a detailed security certification list.
Use the Form Plume alternatives hub to review more hosted form backends with the same comparison structure. Before switching, shortlist the requirements that actually affect your workflow—monthly volume, file limits, searchable retention, spam review, authenticated delivery, API access, and the integrations your team already uses.
One line. Zero backend.
