Splitforms is the newest entrant in this hub and the one competing hardest on generosity: 500 free submissions a month, unlimited forms, $5/month intro pricing — and, notably, a free MCP server on every tier that can create forms. The comparison below looks at how deep each agent surface actually goes, and what delivery guarantees back it.
The short answer
Furrow Forms is the better choice when agents need the full lifecycle — account registration, whole-site provisioning, settings updates, and webhook delivery they can verify. Splitforms is the better choice for a generous free tier and the cheapest paid entry, with a lighter MCP that can create (but not update) forms.
Furrow Forms — best for
Full agent lifecycle, agencies, settings cascade, signed webhooks with retries and logs
Splitforms — best for
Free volume (500/mo), lowest-price paid plans, hobby and side projects
Feature by feature
| Capability | Furrow Forms | Splitforms |
|---|---|---|
| Create & configure forms via API | yes Full CRUD over REST + MCP; bootstrap_site provisions a whole site’s forms in one call | no REST covers submit + read submissions only; creation exists solely inside the MCP, and nothing can be updated or deleted programmatically |
| MCP server | yes 26 tools over streamable HTTP or stdio — full lifecycle, from account registration to reading submissions and Stripe billing links | partial Real and free on all tiers, but a local npx process with 7 read-heavy tools; create_form is the only write |
| Agent cold-start (account via API) | yes Agents register accounts via GET/POST /api/register; the human reads one email code | no A human signs up and copies an sk_mcp token from the dashboard first |
| Site-level settings, inherited by forms | yes Security and routing configured once per website; every form inherits | no Per-form configuration |
| Signed webhooks with retries + log | yes HMAC-SHA256 signed, retried with backoff, logged, testable — all tiers | partial HMAC-signed (Pro+), but explicitly no automatic retries — a missed delivery is gone |
| Spam protection | yes Honeypot + timing field + Turnstile + domain allowlist + rate limits + server-side filtering, on by default; spam never counts toward quota | yes Honeypot, time-trap, AI content scoring, rate limits, optional reCAPTCHA — and spam never counts toward quota |
| API access on the free tier | yes The whole product on the free tier, volume-capped | partial MCP is free on all tiers; webhooks, exports, and integrations are paid |
| File uploads | yes Opt-in per website, inherited by every form; files land in a private per-site inbox (PDF, JPEG, PNG, WebP by default) — emails and webhooks link to it, never to raw file URLs | partial 5 files × 5 MB per submission, paid plans with storage integration |
| Native integrations | no Signed webhooks are the integration story | partial Sheets, Notion, Airtable, Slack, Discord, Telegram, Zapier — paid plans |
| Whole-site provisioning in one call | yes bootstrap_site: client + website + all forms, idempotent | no One form at a time via create_form |
Pricing
| Furrow Forms | Splitforms | |
|---|---|---|
| Free tier | $0 — 100 subs/mo, full API + MCP | $0 — 500 subs/mo, unlimited forms, MCP included |
| First paid tier | $199/yr flat per workspace — 10k subs/mo, unlimited forms & sites | Pro $5/mo intro (list $15/mo) — 5,000 subs/mo |
| Long-term deal | One flat $199/yr | 3-Year plan $59 one payment (intro; list $99) — 15,000 subs/mo |
Splitforms wins on sticker price, with intro-pricing asterisks. Furrow’s $199/yr buys the deeper control plane: full CRUD, cold-start, cascade, and webhook delivery with retries and a log — none of which Splitforms offers at any tier.

Honest trade-offs
FAQ
Yes when you need the full agent lifecycle and delivery guarantees: Furrow Forms supports account cold-start, form updates, settings inheritance, and signed webhooks with automatic retries. Splitforms is a strong budget pick with a generous free tier and a create-only MCP.
Splitforms’ MCP is free and real, but it runs as a local npx process, requires a dashboard-copied token, and its only write tool is create_form — forms cannot be updated or deleted programmatically. Furrow Forms offers hosted MCP with full CRUD, agent account registration, and one-call whole-site provisioning.
Splitforms: 500 submissions/month, unlimited forms, MCP included, webhooks and integrations paid. Furrow Forms: 100 submissions/month, unlimited forms, and the entire product — management API, MCP, signed webhooks with retries, Turnstile — with no feature gates.
No — Splitforms documents that webhooks are attempted once with an 8-second timeout and are not retried. Furrow Forms retries failed deliveries with backoff up to 8 attempts over ~24 hours and keeps a per-project delivery log.
