Web3Forms

Role

Backs the <ContactForm> component on every site. The access key is domain-bound so it can ship in client JS without leaking server credentials.

Free tier

• Unlimited submissions
• Unlimited domains per access key
• Email forwarding included
• Spam protection (hCaptcha optional)

Card / subscription required?

NO. Sign-up is email-only — Web3Forms emails the access key after verifying the address. No payment method requested.

Alternatives

• Formspree — fallback
• Formspark
• FormKeep
• Pageclip

Swap cost

Low — same form-POST shape, swap the action URL and the key field name. Wrapped behind @chirag127/contact-form.

Why this is our pick

Truly free, browser-only, domain-binding means no server token to leak, and the spam protection is good enough out of the box.

Cross-refs

• Formspree — fallback
• No card-on-file rule
