How does FormFork work without a backend server?

Point any standard HTML form action attribute or JavaScript fetch request to your unique FormFork endpoint URL (https://formfork.io/f/your-form-id). FormFork validates fields, filters spam via Honeypot and domain shields, stores the submission, sends email alerts, and triggers webhooks automatically.

Does FormFork work with React, Next.js, and WordPress?

Yes. FormFork works with plain HTML, React, Next.js, Vue, Astro, and static sites via REST/Multipart endpoints, and includes the official FormFork Connect WordPress plugin with native Elementor widget, Gutenberg block, shortcode, and in-dashboard Form Builder.

Is there a free plan available on FormFork?

Yes. FormFork offers Free ($0/mo — up to 3 forms and 100 submissions/mo), Growth ($8/mo — up to 10 forms and 10,000 submissions/mo), Agency ($39/mo — up to unlimited forms and unlimited submissions/mo) with custom branding, webhooks, and priority support.

What happens if my Google Drive disconnects during a form submission?

FormFork automatically falls back to storing the uploaded file in your workspace storage pool so you never lose a customer submission.

Architectural Breakdown · Production Capabilities

How FormFork powers file uploads & google drive sync

01.

Plan-Aware Per-File & Workspace Quotas

File fields in the Visual Studio automatically inherit your account plan limit (e.g., 5 MB, 25 MB, or 100 MB per file), validating file size and extension on both client and server.

Client + Server MIME & Size Enforcement

02.

Direct Google Drive Offloading (drive.file)

Connect your Google account with one click. FormFork creates a dedicated "FormFork Submissions" folder in your Google Drive and streams incoming attachments directly to your cloud.

Bypasses Local Quota When Drive Sync Is Active

03.

Structured files[] Array in Submission API

When your application calls GET /api/submissions, every submission includes a normalized files[] array with direct view/download URLs alongside human-readable data fields.

Ready for Custom Dashboards & AI Agents

04.

One-Click Local-to-Drive Migration

Already collected files on FormFork storage? Trigger a batch sync from your dashboard to transfer existing local attachments to Google Drive and free up workspace quota.

Zero Downtime Storage Offload

Technical FAQ · Answers for Developers & Teams

Frequently asked questions about File Uploads & Google Drive Sync

No. FormFork strictly requests the non-invasive drive.file OAuth scope, which means it can only access the specific folder and files that FormFork itself creates.
