What is Basin?

Basin is a form backend that competes on what happens to a submission after it arrives rather than on price. Your HTML posts to a Basin endpoint, and from there it runs the submission through a spam stack and optional email and phone validation - each paid plan includes a monthly allowance of validation credits, from 100 to 3,000 - before storing it and notifying you. Retention is a first-class setting rather than an afterthought: 30 days on the free plan, a year on Starter, unlimited from Growth upward, which is unusual in a category where archives are usually the first thing cut. Zapier is available even on the free plan, but the direct destinations most people actually want - Google Sheets, Slack, Discord and webhooks - do not appear until the Growth tier.

Key features

Where it saves to

Email inbox and dashboard · Google Sheets (Growth+) · Slack and Discord (Growth+) · Webhooks (Growth+) · Zapier (all tiers)

Pricing

Free covers one form, 50 submissions a month and a 30-day archive. Billed yearly, Starter is $12.50/mo for 3 forms and 250 submissions with a 365-day archive; Growth is $24.17/mo for unlimited forms, 1,000 submissions, unlimited retention and the direct integrations; Pro is $30.62/mo for 5,000 submissions; and Agency is $81.25/mo for 25,000. Every plan carries a 14-day trial and a 30-day money-back guarantee.

Best for

Agencies and freelancers running client forms where a bad address costs a lead - the built-in email and phone validation is the reason to pick Basin over a cheaper endpoint. Less compelling if you only need submissions in a spreadsheet.

Pros

  • Email and phone validation built in, with credits included on every paid plan
  • Unlimited retention from the Growth tier - most rivals cap the archive
  • Zapier works on the free plan, unlike most competitors
  • 14-day trial plus a 30-day money-back guarantee on every tier

Cons

  • Google Sheets, Slack and webhooks are locked until the $24.17/mo Growth tier
  • Free plan allows only one form and 50 submissions a month
  • No Notion destination, unlike Formspark, Web3Forms and Formcarry

FAQ

What does Basin do that other form backends do not?

Validation. Every paid plan includes a monthly allowance of email and phone verification credits, from 100 on Starter to 3,000 on Agency, so a mistyped or disposable address is caught as the submission arrives rather than when a reply bounces.

Does Basin integrate with Google Sheets?

Yes, but from the Growth tier at $24.17/mo billed yearly. Slack, Discord and webhooks unlock at the same point. Zapier is the exception - it works on every plan, including free, so a Sheets route is possible earlier via Zapier.

How long does Basin keep submissions?

Thirty days on the free plan, 365 days on Starter, and unlimited from Growth upward. Unlimited retention this far down the price list is rare - most competitors cap the archive on every tier.

Is there a free version of Basin?

Yes: one form, 50 submissions a month, and a 30-day archive, with spam filtering and Zapier included. It is enough to run a single low-traffic contact form.
