Side-by-side rows for the things developers ask about when evaluating FormBackend.
Long-form prose for the developer who wants the substance behind the table — what each platform is actually good at, and what they're not.
FormBackend is a stable, multi-year form-to-email service. If you're already using it and it works, there's no urgent reason to switch.
splitforms is the better starting point for a new project: larger free tier, cheaper paid tier ($5/mo vs $8/mo), AI spam classification, signed webhooks on free, an open API on every plan, and a $59 one-time 4-Year plan if you want to avoid recurring billing.
The most common trigger is the modernization gap. FormBackend's feature set was strong in 2017–2019 but hasn't evolved at the same rate as the developer-first form backends that emerged after it. splitforms ships an AI spam classifier, MCP server for AI agents, and signed webhooks on free — features that match a 2026-vintage development workflow.
The second trigger is pricing. FormBackend's $8/mo Basic vs splitforms's $5/mo Pro at higher volume is a clear cost delta at any team size.
The third trigger is the one-time payment option. splitforms's $59 4-Year plan covers 15,000 submissions/month for 48 months; FormBackend is recurring-only.
Free tier: splitforms 1,000/month, unlimited forms. FormBackend small free tier with branded messages.
Cheapest paid: splitforms $5/mo. FormBackend $8/mo.
Spam: splitforms AI classifier + honeypot. FormBackend traditional filters.
Webhooks: splitforms signed with retries on free. FormBackend has webhooks; retry/signing behavior is thinner.
API: splitforms open REST + MCP. FormBackend functional API, no MCP.
One-time pricing: splitforms $59 4-year plan. FormBackend recurring only.
"I'm paying $8/mo for features I could get for $5." splitforms's Pro plan is $5/mo for 5,000 submissions.
"My spam filter misses AI-written submissions." splitforms's classifier is trained on modern form spam.
"I want signed webhooks on the free tier." splitforms ships them.
"I want an MCP server for my AI agent." splitforms ships one.
