Keep the same 500-submission free allowance while adding file uploads, 60-day history, and a cryptographically signed webhook before you pay. Form Plume makes a small form production-ready earlier.
Side by side
Static Forms is not a barebones email forwarder: it has a dashboard, a visual builder, extensive CAPTCHA support, native destinations, and an ambitious paid tier. The meaningful differences are where uploads and webhooks begin, whether webhook payloads can be authenticated, how long free submissions remain available, and whether AI replies matter. Static Forms annual prices are shown as published.

Where Form Plume pulls ahead
The free limits look identical at first glance. Form Plume creates separation by including the operational features that turn a contact form into a dependable workflow instead of reserving them for a trial or annual plan.
Static Forms reserves file uploads for paid plans. Form Plume Free includes managed upload storage, so a portfolio brief, support screenshot, or small application can reach your workflow without starting a subscription.
Static Forms documents retry behavior and useful delivery metadata, but its published webhook headers do not include a verification signature. Form Plume signs its included Free webhook, letting the receiver reject forged requests before acting on form data.
Both services advertise 500 monthly submissions on Free. Form Plume retains them for 60 days instead of 30, giving a small team more time to review leads, recover context, and investigate delivery without exporting on a tight schedule.

FAQ
Choose Form Plume when the free workflow needs more than email forwarding. It includes managed file uploads, 60-day submission retention, and a signed webhook alongside the same 500-submission monthly allowance published for Static Forms Free.
The free plans are both $0 and allow 500 monthly submissions. On paid volume alone, Static Forms is cheaper: its current annual Pro offer is $7.50 per month for 25,000 emails, while Form Plume Pro is $12 monthly for 10,000 submissions. Form Plume's advantage is getting uploads and verified automation before that upgrade, plus a broader operational feature set.
Usually. Static Forms and Form Plume both receive ordinary browser POST requests. Create a Form Plume endpoint, replace the action URL and Static Forms API-key field, then test the redirect, notification, CAPTCHA, attachments, and any downstream delivery before changing production traffic.
Form Plume does. Its Free plan includes 100 MB of managed file storage. Static Forms lists upload support on Pro and Agency, caps each file at 4.5 MB, and provides 2 GB or 10 GB of persistent storage depending on the paid tier.
Static Forms' current webhook preview documents content type, user agent, and event headers, but no cryptographic signature header. It retries failed deliveries up to three times. Form Plume includes a signed webhook on Free so your receiver can verify the source before processing the event.
Form Plume is designed for wider routing through native integrations, Zapier, Make, MindCloud, and arbitrary signed webhook destinations. Static Forms has a capable paid catalog of messaging, database, email, and automation targets. Choose Static Forms when one of its direct connections is exactly what you need; choose Form Plume when breadth and verifiable custom delivery matter more.
Static Forms has a solid stack: an automatic honeypot plus reCAPTCHA v2 and v3, Turnstile, hCaptcha, ALTCHA, domain restriction, and a reviewable spam inbox. Form Plume supports the same major CAPTCHA families while adding adaptive filtering, rate controls, email hygiene, manual blocklists, origin rules, and recoverable quarantine.
Not currently. Form Plume Pro provides customizable autoresponders for predictable confirmations, while Static Forms offers standard autoresponders and an optional pay-as-you-go AI Reply that can reference an uploaded knowledge base. Static Forms is the better fit when generated responses are a core requirement.
Yes. Form Plume accepts standard HTML submissions and fetch requests, so it works with React, Next.js, Astro, Vue, Hugo, Jekyll, or a plain static page. You can keep control of the frontend instead of adopting a required SDK or generated form component.
The Form Plume alternatives hub compares hosted form backends using the same practical criteria: submission limits, uploads, webhooks, spam controls, retention, integrations, and the real point where a growing form must pay.
One line. Zero backend.
