Basin alternative: 4 form backends compared

Basin is a solid form backend with strong spam filtering on its higher tiers. People look for a Basin alternative mostly because of the free plan (one form, 50 submissions a month, 30-day retention) and because Sheets, Slack, webhooks and the API sit on the Growth tier and up. We build Formgong, so it is listed first and compared plainly; the others are described from their own public pages, including where they win.

Short answer: The usual reason to leave Basin is the free tier: one form, 50 submissions a month, 30-day data retention, with most integrations starting on paid plans. Formgong's free plan takes 1,000 submissions a month with unlimited forms, email, Telegram and EU storage. Web3Forms offers 250 a month with one access key. Formspree is the pick when its plugin catalogue matters. Stay with Basin for its advanced spam filtering and agency features.

Why people look for a Basin alternative

  • The free plan is a trial in practice. One form endpoint, 50 submissions a month, data kept 30 days, 100MB of file uploads.
  • Integrations are tiered. Zapier is on every plan, but Google Sheets, Slack, webhooks, auto-responses and API access start at Growth, and advanced spam filtering, custom domains and custom SMTP at Pro.
  • Overage is billed. Submissions past the monthly cap are delivered and charged as overage, which is kinder than losing them and still a bill you did not plan.

None of this makes Basin a bad service; its paid tiers are genuinely capable. The question is whether you need them for a contact form.

Where Basin is the better choice

  • Serious spam tooling. Pro adds advanced filtering with location, language and custom content filters, and spam does not count against your quota.
  • Agency features. The Agency tier has multi-step forms, saved incomplete submissions and enhanced deliverability.
  • Virus scanning for uploads on Pro, which few form backends offer at all.

If those map to your needs, Basin earns its tier. The head-to-head with Formgong alone is on Formgong vs Basin.

Switching a Basin form to Formgong

  1. Create a free Formgong account and copy the form's access key.
  2. Change the form's action to https://formgong.com/submit and put the key in a hidden access_key field. Field names stay as they are.
  3. Send a test from the live site, then connect Telegram or more email recipients in the dashboard.

The HTML docs list every hidden field Formgong understands, including _redirect for a thank-you page and the botcheck honeypot.

For volume, Formgong: 1,000 submissions a month with unlimited forms, email, Telegram and CSV export on Free, against Basin's 1 form and 50 submissions with 30-day retention. Web3Forms gives 250 a month with one access key and no dashboard work.

Does Basin delete form submissions?

On the free plan, data is retained for 30 days; the Starter tier keeps it for 365 days and higher tiers indefinitely, per Basin's pricing page. If you need a permanent archive on a free plan, pick a backend whose free tier stores submissions without a clock.

Which Basin alternative has Telegram delivery?

Formgong delivers to Telegram on every plan, including Free, with several chats per form. Formspree lists a Telegram plugin on its plans. Basin's pricing page does not list Telegram.

When should I stay with Basin?

When you use its strengths: advanced spam filtering with custom filters, virus scanning for uploads, multi-step forms and the agency features on its higher tiers. For a plain contact form, those rarely come into play.
