Run custom forms on a managed backend with 500 free submissions, included uploads and a signed webhook, then scale to 10,000 submissions for $12 per month. Form Plume keeps the frontend yours while removing server and deliverability work.
Side by side
Formgrid spans three jobs: visual form building, hosted form processing, and basic lead follow-up. Form Plume concentrates on a production-grade managed backend for forms you already control. This comparison uses Formgrid's current official pages; where those pages publish different Business caps, it relies on the consistent Free and Premium figures instead.
| Decision point | Form Plume | Formgrid |
|---|---|---|
| Hosted plan capacity | 500 free · 10,000 on Pro Pro costs $12 per month and keeps unlimited form endpoints. | 25 free · 1,000 on Premium Formgrid Premium also costs $12 per month; its published Business allowance varies between current official pages. |
| Form creation model | Backend for forms you design and own Use custom HTML, React, Astro, Webflow, or another frontend while Form Plume handles submissions. | Hosted builder and bring-your-own-form endpoint Formgrid can create conversational forms with shareable links or receive posts from an existing HTML form. |
| File uploads | 100 MB included on Free 10 GB on Pro, with uploads available before a paid upgrade. | Paid uploads up to 1 GB per file Formgrid Free lists no file uploads; Premium adds uploads and CSV export. |
| Webhooks and automation | 1 signed webhook on Free Pro includes unlimited signed webhooks alongside API access and external app integrations. | Webhook automation on Business Formgrid promotes webhooks for Zapier, Make, Slack, Notion, Airtable, and other destinations. |
| Google Sheets and integrations | Native destinations plus broad automation routes Sheets, Slack, Discord, ActiveCampaign, Mailchimp, Zapier, Make, MindCloud, and signed webhooks | First-party Google Sheets sync Free includes a small one-time sync, Premium includes 500 rows monthly, and Business advertises unlimited rows. |
| Spam protection | Layered, reviewable defenses CAPTCHA choices, origin restrictions, rate limits, blocklists, email hygiene, adaptive scoring, and recoverable quarantine | Honeypot, CAPTCHA, rate limiting, and filters Formgrid documents automatic bot controls and its repository includes reCAPTCHA support and manual spam management. |
| Lead follow-up workflow | Purpose-built submission operations Search, delivery status, exports, autoresponders, integrations, and recoverable spam in one inbox | Built-in lead pipeline and reminders New, Contacted, and Converted stages, private notes, follow-up emails, and conversion tracking |
| Hosting and source access | Fully managed SaaS Form Plume operates the backend, storage, updates, and deliverability; it is not offered for self-hosting. | Managed cloud or MIT-licensed self-hosting Run Formgrid with Docker, audit its TypeScript code, and choose local, MinIO, S3, or Google Cloud Storage. |
Where Form Plume pulls ahead
Formgrid is unusually flexible for an open-source newcomer. Form Plume pulls ahead when the priority is managed capacity, included production features, signed delivery, and a wider operational safety net rather than running Docker or using the built-in lead board.
Formgrid Premium publishes 1,000 monthly submissions for $12. Form Plume Pro includes 10,000 at the same monthly price, along with 10 GB of file storage, unlimited signed webhooks, API access, exports, autoresponders, and external integrations.
Formgrid's managed Free plan is a useful 25-submission trial, but uploads are paid and its richer automation sits higher in the plan ladder. Form Plume Free includes 500 submissions, 100 MB of uploads, 60-day retention, spam controls, notifications, and one signed webhook.
Formgrid's builder and New-to-Converted lead board are valuable when one tool must also create forms and mimic a small CRM. Form Plume instead invests in submission search, signed delivery, integration breadth, retention, spam recovery, exports, and predictable scaling behind your own interface.

Formgrid
Its visual builder, lead stages, notes, follow-up reminders, and conversion rate can replace separate form and lightweight CRM tools.
Agency standardizing managed client endpoints
Form Plume
Unlimited forms, broader routing, explicit storage and retention, and deeper spam operations reduce the work around bespoke client frontends.
Technical team requiring source access or private hosting
Formgrid
Its MIT-licensed repository and Docker deployment are the appropriate choice when auditing or operating the application yourself is mandatory.
FAQ
Form Plume is a strong Formgrid alternative when you want the vendor to operate the backend and need more hosted capacity. Its Free plan includes 500 monthly submissions and Pro includes 10,000 for $12 per month, while preserving your existing HTML or framework form.
Their first hosted paid plans both cost $12 per month, but Form Plume Pro includes 10,000 monthly submissions versus Formgrid Premium's published 1,000. Formgrid can cost less when you self-host its MIT-licensed software, although infrastructure, upgrades, email delivery, storage, backups, and incident response then become your responsibility.
Usually. For a normal HTML post, create a Form Plume form, replace the Formgrid action URL, and test fields, redirects, notifications, files, spam handling, and downstream delivery. Recreate any Formgrid-specific lead stages or follow-up reminders in your sales workflow before retiring the old endpoint.
Yes. Form Plume Free includes file uploads with 100 MB of storage, and Pro increases storage to 10 GB. Formgrid's current application pricing says its managed Free plan has no uploads and Premium adds files up to 1 GB each.
Form Plume is stronger when signed webhook delivery must start early: Free includes one signed webhook and Pro includes unlimited signed webhooks. Formgrid advertises webhook-driven Zapier-style automations on Business and also exposes webhook support in its open-source codebase.
Yes. Form Plume supports Google Sheets alongside native destinations, Zapier, Make, MindCloud, and signed webhooks. Formgrid's first-party Sheets sync is one of its clearest strengths, particularly for small teams that want each lead copied directly into a shared spreadsheet.
Not directly. Formgrid includes New, Contacted, and Converted stages, notes, follow-up reminders, and conversion tracking. Form Plume provides a submission operations inbox and routes data into dedicated sales and automation tools, which is better when your team already has a CRM or wants a more flexible integration stack.
No. Form Plume is a managed SaaS and does not market a self-hosted edition. Formgrid is the better fit when an MIT-licensed codebase, Docker deployment, private infrastructure, or selectable local and object-storage adapters are requirements.
Both provide bot defenses. Formgrid documents honeypots, CAPTCHA, rate limiting, automated filters, and manual spam management. Form Plume layers CAPTCHA options, origin restrictions, rate limits, blocklists, email hygiene, adaptive scoring, and a recoverable quarantine so legitimate submissions can be reviewed instead of disappearing permanently.
Compare Form Plume with other endpoint-first services in the alternatives hub, then evaluate each option against the same requirements: submission capacity, uploads, retention, spam recovery, signed delivery, integrations, builder needs, and whether your team wants to operate the backend itself.
One line. Zero backend.
