Why Choose Spike

​
Unlimited Submissions

Web3Forms caps free submissions at 250/month. Spike has no limits.

​
Full Dashboard

Web3Forms sends submissions to your email — there’s no dashboard to view or search past submissions. Spike gives you a full dashboard with search, filtering, and export.

​
Webhooks on Free

Spike includes webhooks on the free plan. Web3Forms requires a paid plan.

​
21+ Integrations

Spike connects to Slack, Discord, Google Sheets, Notion, Airtable, HubSpot, and more. Web3Forms has no native integrations.

​
API Access

Spike provides a full REST API for managing forms and submissions. Web3Forms has no API.

​
More Spam Protection

Both support honeypot and hCaptcha. Spike also supports reCAPTCHA v2/v3, Cloudflare Turnstile, ML-based filtering, email/domain/IP blocklists, and work email validation.

​
When Web3Forms Might Be Better

  • If you want a no-account setup (Web3Forms uses an access key instead of an account)
  • If 250 submissions/month is enough and you only need email delivery

​
Setup Comparison

Spike: 
<form action="https://api.spike.ac/f/YOUR_FORM_SLUG" method="POST">
  <input type="text" name="_gotcha" style="display:none">
  <input type="email" name="email" required>
  <textarea name="message" required></textarea>
  <button type="submit">Send</button>
</form>
Web3Forms: 
<form action="https://api.web3forms.com/submit" method="POST">
  <input type="hidden" name="access_key" value="YOUR_ACCESS_KEY">
  <input type="checkbox" name="botcheck" style="display:none">
  <input type="email" name="email" required>
  <textarea name="message" required></textarea>
  <button type="submit">Send</button>
</form>
Both are simple to set up. The difference is what you get after — Spike gives you a dashboard, webhooks, integrations, and an API. Web3Forms gives you email delivery.
