SplitForms vs Formspark
Formspark alternative: signed webhooks and monthly capacity
Choose SplitForms as a Formspark alternative when signed webhook deliveries, native storage-backed uploads and recurring monthly capacity matter more than prepaid billing. Pro is $5/month for 5,000 submissions/month. Formspark can cost less for a quiet site that consumes a bundle slowly; compare the complete workflow before switching.

Honest take
When should you stay with Formspark?
Stay with Formspark if one of these matters more to you than switching:
- A non-expiring balance can be economical for irregular traffic
- No recurring payment for the documented upgrade bundle
- Free integrations and exports documented in its plan guide
Leave Formspark in about 10 minutes
How switching works
Keep your HTML, field names and styles. Only the action URL changes, plus one hidden access_key field.
Swap the form action
Point your form at https://splitforms.com/api/submit and add one hidden access_key field. Field names and styling stay the same.
Test, then cut over
Send a test entry, confirm it reaches your inbox and dashboard, then remove the old endpoint.
Where submissions go
Every submission lands in your inbox and a searchable dashboard on every plan, including Free. Paid plans add webhooks and integrations:
AI agents can manage forms through the splitforms MCP server, included on every plan.

Common questions
Frequently asked questions.
View all FAQsDoes Formspark have signed webhooks?
Its current webhook documentation says it does not sign requests. SplitForms offers HMAC-SHA256 signed webhooks on paid plans.
Is Formspark only protected by a honeypot?
No. Its current documentation lists automatic filtering and several optional verification providers in addition to honeypots.
Is changing the action URL enough?
Use /f/YOUR_ACCESS_KEY for the compatibility endpoint, or add access_key when using /api/submit. Also verify special controls, notification settings, uploads, redirects and integration mappings.
Deep dive
The full picture, no fluff.
Short, honest answers on pricing, migration, and why teams move from Formspark to splitforms.
01Prepaid credits and monthly allowances solve different needs
A prepaid balance can last a long time for a brochure site, while a recurring allowance may suit a regularly active lead funnel. Calculate expected usage across the life of the project and include collaborators, storage and operational features. Do not compare 50,000 total credits with a monthly limit as if both reset.
SplitForms Free starts with 500 total submissions. Pro is $5/month for 5,000 submissions/month, and Annual is $49/year for 15,000 submissions/month. If you rarely receive forms and do not need the extra workflow features, Formspark’s billing model deserves serious consideration.
02Signed webhooks provide a concrete reason to switch
Formspark’s webhook documentation explicitly states that requests are not signed. SplitForms paid webhooks use HMAC-SHA256, so a receiver with the signing secret can verify the raw request body before processing it.
Signatures do not remove the need to validate fields or handle repeated deliveries. SplitForms uses an eight-second timeout and one automatic retry after roughly two seconds for network errors, timeouts and 5xx responses; it does not retry 4xx responses. Design the receiver around those documented constraints.
03Plan uploads as a separate migration step
Formspark’s guide uses a third-party provider to upload files and stores the resulting URL. SplitForms can store incoming multipart files through its Storage integration on paid plans. That changes the implementation and access workflow, so preserve existing file links until you have a deliberate retention plan.
SplitForms currently accepts up to five files of 5 MB each per submission. If your existing uploader accepts larger files, keep a compatible external workflow or adjust the limits openly. Never assume changing the action URL imports old attachments.
04Both products have more than a hidden spam field
Formspark documents automatic filtering plus Botpoison, reCAPTCHA, hCaptcha, Turnstile, custom spam words and honeypots. SplitForms also applies server-side controls. Evaluate false positives and review behavior instead of assuming a shorter feature description means weaker protection.
The team limits in Formspark’s pricing page and documentation differ. Confirm the applicable paid limit if collaboration affects your purchase. This comparison avoids turning that inconsistency into an unsupported unlimited-members claim.
05Migrate without changing the visitor’s form fields
Keep your visitor field names, labels and validation. Create the receiving form in SplitForms, then set action to https://splitforms.com/f/YOUR_ACCESS_KEY. Alternatively, use https://splitforms.com/api/submit and add a hidden access_key input. Copy the actual form access key from Setup; an account token is not a substitute.
Recreate notification recipients, redirects and any autoresponder in the dashboard. Check the upload plan and Storage connection. For webhooks, update payload mapping and signature verification. Test the deployed page, confirm the stored answers and attachments, then verify email and the receiving integration separately.
