FormBold alternative: same HTML form, one new URL

The most common trigger is the price-per-submission gap. FormBold's Starter plan is $6/mo billed yearly (or $10/mo month-to-month) for 3,000 submissions; splitforms Pro is $5/mo for 5,000 — more volume for less. Over three years, that's roughly $216 on FormBold's yearly-billed Starter plan vs $180 on splitforms Pro, or $147 on the Annual plan — meaningful savings for a side project, dramatic savings for an agency running multiple sites.

The second trigger is webhook verifiability. splitforms signs every webhook payload with HMAC-SHA256 — an `sha256=`-prefixed signature header your receiver can verify — scopes each webhook to a single form, and ships a free webhook tester at splitforms.com/webhook-tester so you can inspect the exact payload before wiring production. Each delivery has an 8-second timeout and one automatic retry on network errors, timeouts and 5xx responses, so keep your receiver fast.

The third trigger is choice of integration style. splitforms has native Notion, Airtable, Google Sheets and Slack integrations on paid plans, and a signed webhook into your own serverless function when you want a transparent contract: you see the JSON, you control the transformation, you log everything.

Free tier

splitforms 500 submissions total; FormBold 100 submissions/month.

Entry-level volume

splitforms Pro is $5/mo for 5,000 submissions; FormBold's Starter plan is $6/mo billed yearly (or $10/mo month-to-month) for 3,000. More volume for the same or less.

Webhooks

splitforms includes HMAC-SHA256 signed webhooks (one retry after ~2s on network errors, timeouts and 5xx; not on 4xx; 8-second timeout) on paid plans. FormBold's webhooks are functional but observability is thinner.

Spam protection

splitforms uses smart spam filtering plus honeypot. FormBold uses honeypot plus basic CAPTCHA.

Notion / Airtable / Telegram

FormBold has native connectors for all three. splitforms has native Notion and Airtable integrations on paid plans and reaches Telegram via webhook.

API

splitforms ships an open REST API and MCP server on every plan. FormBold's API is more limited.

Notifications

splitforms stores accepted submissions before attempting email; delivery and inbox placement depend on provider and recipient settings.

Yearly billing

splitforms Annual is $49/year for 15,000 submissions/month. FormBold's Starter is $6/month billed yearly for 3,000.

• “FormBold's Starter plan tops out at 3,000/month.”

  splitforms Pro is $5/mo for 5,000 submissions — more headroom for about the same price.

• “I can't verify a webhook actually came from my form backend.”

  splitforms signs every payload with HMAC-SHA256 (`sha256=` header prefix), and the free webhook tester at splitforms.com/webhook-tester shows the exact payload before you wire production.

• “The Notion connector failed silently and I have no audit trail.”

  A splitforms webhook into your own serverless function gives you full logs, transformations, and retry control.

• “I'm getting AI-generated spam slipping past CAPTCHA.”

  splitforms runs every submission through smart spam filtering: automatic, rule-based scoring of content signals such as links, spam phrases and disposable email addresses.

• “I want to expose form data to a Claude or Cursor agent.”

  splitforms ships an MCP server natively.

FormBold's Notion and Airtable connectors are easy to set up, and so are splitforms' native Notion and Airtable integrations on paid plans. The difference shows up when you need more than 'submission lands in a row': a native connector hides the JSON payload, so you can't transform fields before they hit Notion, add conditional logic, or debug a missing row from an audit trail.

A webhook is a transparent contract. You see exactly what JSON splitforms sends, you control the transformation in your own code, you log every attempt, and you can add any logic you want — deduplication, enrichment, conditional routing, fallback destinations. For a marketing team that just wants 'submission lands in Notion,' the connector is fine. For an engineering team that wants observability and the ability to evolve the integration, the webhook architecture is more durable — and on splitforms, both options come with the paid plans.

Five things make the difference for developers. First, the free tier gives 500 submissions up front (vs FormBold's 100/month) and includes the dashboard and email notifications, while Pro adds signed webhooks and file uploads for $5/month. Second, the Pro tier packs more volume for about the same price as FormBold's Starter plan. Third, HMAC-SHA256 signed webhooks (one retry after ~2s on network errors, timeouts and 5xx; not on 4xx; 8-second timeout) ship on paid plans. Fourth, the API is open and includes an MCP server for AI agents. Fifth, the Annual plan is $49/year for 15,000 submissions/month.

Notion and Airtable connect natively on paid plans. Telegram works via webhook: point the splitforms webhook at a tiny serverless function (Vercel, Cloudflare, AWS Lambda, anywhere) that sends the message.

Step 1: sign up at splitforms.com for a free access key (no credit card). Step 2: swap your form's action from `https://formbold.com/s/YOUR_ID` to `https://splitforms.com/api/submit`. Step 3: test a submission and confirm it lands in the dashboard.

If you're using FormBold's Notion or Airtable connector, connect the matching splitforms integration from the dashboard (paid plans). For Telegram, point the webhook at a small function that calls your bot's `sendMessage` endpoint, which gives you full control over the message format.

Is splitforms a viable FormBold alternative? Yes. Every core capability — POST endpoint, dashboard, webhooks, file uploads, spam filtering, custom redirects, CC recipients — is covered, with 500 free submissions up front and cheaper paid tiers.

What about the Notion / Airtable / Telegram integrations? Notion and Airtable are native splitforms integrations on paid plans. Telegram works through a webhook to a small function that calls your bot.

Are the webhooks verifiable? Yes — every payload is HMAC-SHA256 signed with an `sha256=`-prefixed header so your receiver can authenticate it. Each delivery has an 8-second timeout and one automatic retry on network errors, timeouts and 5xx responses; validate the payload shape first with the free tester at splitforms.com/webhook-tester.

Does splitforms support file uploads? Yes, on paid plans (Pro and Annual).

Is there a per-form limit? No. Every plan — Free, Pro and Annual — includes unlimited forms.

Is there a yearly plan? Yes. Annual is $49/year for 15,000 submissions/month with every Pro feature, about $4.08/month.
