Paid plans, billed yearly, are Starter at $12.50/month (250 submissions, 3 forms), Growth at $24.17 (1,000, unlimited forms, webhooks), Pro at $40.83 (5,000) and Agency at $108.33 (25,000).

How much does each Basin plan cost?
Basin has a Free plan and four paid tiers. Webhooks start on Growth, the pricing page lists retention as unlimited from Growth up (see the note below on Basin's 48-month deletion policy), and every plan, Free included, comes with file upload storage.
| Plan | Price (billed yearly) | Billed monthly | Submissions/month | Forms | Retention | Storage | Webhooks |
|---|---|---|---|---|---|---|---|
| Free | $0 | $0 | 50 | 1 | 30 days | 100 MB | No |
| Starter | $12.50/mo ($150/yr) | $15 | 250 | 3 | 365 days | 500 MB | No |

Checked October 10, 2026 on usebasin.com/pricing. *Prices shown are list prices. Basin's new-customer coupon (50% off for six months) shows Pro as $30.62/mo ($367 for the first year) and Agency as $81.25/mo ($975) on yearly billing. †Basin's pricing page and docs list retention as unlimited on Growth and above, but its GDPR page says submissions are deleted automatically after 48 months, so treat four years as the practical ceiling and confirm with Basin if you need longer. Extra submissions are billed monthly, from $5.25 per 1,000 down to $2.00 per 1,000 at the highest volumes.
Basin pricing vs splitforms: how do the free plans compare?
Basin's published Free tier is built around one low-volume endpoint. splitforms removes that ceiling: 500 free submissions total spread across as many forms as you create, with owner email notifications included on every plan — not gated behind a paid tier.
| Limit | Basin Free | splitforms Free |
|---|---|---|
| Free submissions | 50/month | 500 total |
| Free form endpoints | 1 endpoint | Unlimited forms |
| Retention | 30 days on Free, 365 on Starter, listed as unlimited from Growth (the GDPR page says 48 months) | No automatic expiry on any plan |
| File uploads | Free includes 100 MB uploads | Paid plans only: 500 MB on Pro, 5 GB on Annual |
| Webhooks | From Growth ($24.17/mo billed yearly) | HMAC-signed, on Pro ($5/mo) and Annual ($49/yr) |
| Spam protection | SpamCheck.ai content analysis, CAPTCHA choice and honeypot on every plan | Honeypot, time-trap field, rate limits, spam heuristics, optional reCAPTCHA v2 |
| Developer workflow | Hosted form endpoint and dashboard | POST endpoint, REST API, signed webhooks (paid plans), MCP, dashboard |
| Best fit | Low-volume forms that fit Basin's free cap | Developer sites, agencies, and static sites with room to grow |

When is Basin's free plan enough?
Basin and splitforms solve the same problem at different traffic levels. Use the checklist below to see which one fits the site you're building today.
- Your website has one low-volume form and 50/month is enough.
- You like Basin's dashboard and do not need a larger free tier.
- Your team already uses Basin and switching would not save meaningful time.
- You want 500 free submissions total before upgrading.
- You manage multiple forms, client sites, frameworks, or environments.
- You want signed webhooks, a REST API, built-in spam filtering, and a developer-first dashboard.
How do you move a Basin form to splitforms?
You don't need to rebuild the form. Basin and splitforms both accept a standard HTML POST, so switching is a one-line endpoint change plus a hidden field.
- 01
Get a free access key. Sign in to splitforms and copy the access key for your form. The Free plan needs no credit card.
- 02
Swap the endpoint. Change the form’s action from Basin’s URL to https://splitforms.com/api/submit and keep method="POST". Every other field stays the same.
- 03
Keep the honeypot field. Leave the hidden botcheck input empty so real submissions pass spam filtering.
- 04
Send a test submission. Submit the form once, confirm it lands in your splitforms dashboard and inbox, then retire the old Basin form ID.
