Run unlimited forms and collect 500 submissions on Free, then move to 10,000 submissions for $12 per month. Form Plume keeps the form backend focused, generous, and ready for automation without charging for a visual builder you may not need.
Side by side
Basin has grown into a broad forms and lead-management platform. This comparison separates that breadth from the everyday endpoint economics: how many forms and submissions you receive, how long data stays available, and when automation unlocks.
| Decision point | Form Plume | Basin |
|---|---|---|
| Free forms and submissions | Unlimited forms · 500 submissions / month Room to run several real forms without splitting accounts. | 1 form · 50 submissions / month Basin describes Free as suitable for testing and light use. |
| Submission retention | 60 days on Free 2 years on Pro | 30 days on Free Starter retains data for 365 days; Growth and above are unlimited. |
| Production capacity | 10,000 submissions for $12 / month Unlimited forms, 10 GB of files, and two years of retention. | 250 submissions from $12.50 / month Starter's published price is billed yearly; overages are billed separately. |
| File uploads | Included on Free 100 MB on Free and 10 GB on Pro | Included on Free 100 MB of storage; individual submissions may upload up to 100 MB. |
| Signed webhooks and API | 1 signed webhook on Free Pro adds unlimited signed webhooks, API access, and CSV export. | Growth and above Signed, retrying webhooks and REST API access are paid-plan features. |
| Integration routes | Native apps plus broad automation paths Slack, Discord, Sheets, ActiveCampaign, Mailchimp, Zapier, Make, MindCloud, and signed webhooks | Direct apps, automation hubs, and webhooks Zapier starts on Starter; Slack, Sheets, API access, and webhooks begin on Growth. |
| Spam and lead quality | Layered protection with recoverable quarantine Four CAPTCHA choices, origin controls, adaptive scoring, rate limits, blocklists, and email hygiene | Deep location, content, and attachment controls CAPTCHA options, SpamCheck.ai, validation, geo filters, custom rules, and virus scanning by plan |
| Visual building and analytics | Bring your own frontend A focused endpoint, searchable inbox, exports, and delivery analytics. | Form Studio plus conversion analytics Drag-and-drop hosted forms, conditional logic, GTM events, funnels, and multi-step tracking |
Where Form Plume pulls ahead
Basin's builder, funnel analytics, validation credits, and AI features can be valuable. Form Plume makes a different trade: more forms and far more submission capacity at the tiers most custom-form teams actually start with.
Basin Free permits one form endpoint and 50 legitimate submissions per month. Form Plume Free supports unlimited forms and 500 submissions, so a portfolio, newsletter, client microsite, and application form can share one organized account.
Basin includes Zapier on Starter, but signed webhooks and API access begin on Growth. Form Plume includes one signed webhook on Free and unlocks unlimited signed webhooks, external integrations, and API access on its $12 Pro plan.
Form Studio, hosted Basin Sites, and conversion funnels add breadth to Basin. When your forms already live in React, Webflow, static HTML, or a design system, Form Plume directs more of the plan value toward collection volume, retention, and routing.

FAQ
Form Plume is a strong Basin alternative when you design the frontend yourself and want the subscription focused on processing, storage, and delivery. Free includes unlimited endpoints, 500 monthly submissions, uploads, and one signed webhook.
Basin Free lists one endpoint, 50 monthly submissions, 30-day retention, 100 MB of files, basic analytics, and Zapier. Form Plume Free provides unlimited forms, 500 monthly submissions, 60-day retention, 100 MB of storage, and a signed webhook.
Usually the visible form can stay exactly as it is. Create a Form Plume endpoint, replace the Basin URL in the action attribute, review any hidden redirect fields, and test notifications, files, spam behavior, and downstream delivery before retiring the old endpoint.
Yes. Basin Form Studio can design hosted or embedded forms with conditional logic, validation, themes, and multi-page flows. Form Plume is designed to receive forms you build with HTML, a website platform, or a frontend framework, keeping control of markup and styling in your codebase.
Form Plume makes automation available earlier: one signed webhook is included on Free, and Pro includes unlimited signed webhooks plus API access. Basin's capable signed webhooks, retry controls, custom payload templates, and REST API begin on Growth according to its current plan table.
Form Plume covers the core layers with reCAPTCHA v2 and v3, hCaptcha, Turnstile, honeypots, domain controls, adaptive scoring, rate limits, blocklists, email hygiene, and recoverable quarantine. Basin remains particularly strong for plan-gated country, radius, language, content, phone-validation, and attachment-virus controls.
Both cover important form workflows. Basin documents Zapier, Make, Integrately, Google Sheets, Mailchimp, Slack, Asana, Teams, and custom webhooks. Form Plume combines native destinations with Zapier, Make, MindCloud, and arbitrary signed webhook targets, making it especially flexible for long-tail app routing.
For submission volume, Form Plume is materially better value. Pro costs $12 monthly and includes 10,000 submissions. Basin Starter publishes an annual-billing price of $12.50 per month for 250 submissions, while Growth publishes $24.17 per month billed yearly for 1,000. Basin may justify that premium when its broader builder and lead tooling replace other products.
Choose Basin when its drag-and-drop Studio, hosted sites, conversion and funnel analytics, incomplete-submission capture, AI lead agent, or granular geographic filters are requirements. Choose Form Plume when you already own the form UI and want more endpoints, volume, and early automation for less.
The Form Plume alternatives hub compares hosted form backends with the same criteria, including submission allowances, storage, retention, spam controls, integrations, and automation. You can also review the full Form Plume feature set before changing an endpoint.
