Basin pricing and free plan limits, compared to splitforms.
Short answer: Basin's listed Free plan gives you 1 form endpoint, 50 submissions per month, and 30-day retention before a paid tier kicks in. splitforms turns that into a single POST endpoint — https://splitforms.com/api/submit — that any HTML or JSON form can call, with 500 free submissions a month across unlimited forms, dashboard storage, and built-in spam filtering. Starter adds signed webhooks.
Basin pricing vs splitforms pricing: the free-plan gap
Basin's published Free tier is built around one low-volume endpoint. splitforms removes that ceiling: 500 free submissions per month 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/month |
| Free form endpoints | 1 endpoint | Unlimited forms |
| Free retention | 30 days | Dashboard storage on Free |
| Spam protection | Basic spam protection | Honeypot, time-trap field, rate limits, spam heuristics, optional reCAPTCHA v2 |
| Developer workflow | Hosted form endpoint and dashboard | POST endpoint, REST API, signed webhooks (Starter+), MCP, dashboard |
| Best fit | Low-volume forms that fit Basin's free cap | Developer sites, agencies, and static sites with room to grow |

When Basin's free plan is enough — and when it isn't
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 per month 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 to 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.
<form action="https://splitforms.com/api/submit" method="POST">
<input type="hidden" name="access_key" value="YOUR_ACCESS_KEY" />
<input type="checkbox" name="botcheck" style="display:none" tabindex="-1" />
<input name="name" required />
<input name="email" type="email" required />
<textarea name="message" required></textarea>
<button type="submit">Send</button>

When is Basin a good fit?
Basin can be a good fit when you like its dashboard and only need one low-volume endpoint. It is also established and has a polished form-submission workflow.
When is splitforms a better Basin alternative?
splitforms is better when you want more free submission headroom, unlimited forms on every plan, signed webhooks and native integrations on Starter, built-in spam protection (honeypot, time-trap field, rate limits), developer-first API docs, and a $5/month Pro plan with CC/BCC.
How do I connect my form to splitforms instead of Basin?
Point your form’s action at https://splitforms.com/api/submit with method="POST" and a hidden access_key input that identifies your form. Multipart submissions and file fields are supported, and you can also submit as fetch/JSON from React, Next.js, or any frontend.
Does splitforms support webhooks and Zapier like Basin?
Basin's documented Free plan includes Zapier integration. splitforms's Starter plan ($1/month) adds HMAC-SHA256 signed webhooks (single delivery attempt, 8-second timeout, no automatic retries), plus native 1-click integrations for Google Sheets, Notion, Airtable, Slack, Discord, Telegram, WhatsApp, and Mailchimp. Zapier, Make, and n8n connect through a generic webhook.
What does splitforms cost after the free plan?
Starter is $1/month for 1,000 submissions with CSV/XML/PDF export, webhooks, integrations, and an auto-responder. Pro is $5/month for 5,000 submissions with CC/BCC and priority support. A 3-Year plan is $59 billed every 3 years for 15,000 submissions/month. Business (unlimited) is available by emailing hello@splitforms.com.
Can I read submissions with code instead of Basin's dashboard?
Yes. splitforms has a REST API at GET https://splitforms.com/api/submissions, authenticated with a bearer token from Dashboard → MCP, and a free MCP server (6 tools, including create_form and list_submissions) so AI agents can build and read forms directly.
