Basin vs Web3Forms (2026): which should you pick?

Pick Basin if

• Fits if you run a static site and need submissions emailed without writing server code
• Works for freelancers and agencies handling several client forms

Look elsewhere if

• Tight if you stay on Free, with one form endpoint and 50 submissions a month
• Watch out: webhooks, API access and auto-responses need Growth, and custom email domains need Pro
• Skip it if you want a visual form builder as the main thing, because this is a backend first
• Pricey if your traffic grows, since plans are capped by submissions and extras are billed monthly

Pick Web3Forms if

• Fits if you have a static site and want form entries in your inbox without a server
• Works for developers happy to paste an access key into HTML

Look elsewhere if

• Skip it if you want to know the free plan's limits first, since we couldn't read the pricing page
• Tight if you need autoresponders, webhooks or attachments, which need a paid subscription
• Watch out: submissions are forwarded, not stored, so there's no archive to go back to
• Watch out: the docs put its servers in the US East region
• Too light for anyone who wants a form builder, as the listing shows none

Basin

• Plans are capped by submissions per month; the page says extra submissions are available at rates made for each tier, billed monthly.
• The Free plan has one form endpoint and keeps data for 30 days.
• Auto-responses, webhooks and API access need Growth; custom email domains need Pro.
• Coupon-code discounts for new customers are shown on some plans and are not counted in these prices.

Web3Forms

• The pricing page returned a bot check, so plan prices and limits were not verified.
• Reply-to domain restriction, reCAPTCHA, Turnstile, autoresponder, webhooks and attachments need a paid subscription.
• The docs say submissions are forwarded rather than stored, and servers are in the US East region.
