Basin alternatives in 2026, compared by free tier and price

How do the Basin alternatives compare?

Basin is the baseline row; the nine alternatives that follow are alphabetical. Free tiers are monthly unless marked total. Plans change, so confirm on the vendor's page before you sign up.

splitforms' free allowance is 500 submissions in total rather than per month; Formspark's is 250 in total; the others are monthly. Basin's own spam submissions do not count toward its limits, which none of the other free tiers advertise.

Where do these numbers come from?

splitforms is a competitor; prices were checked on each vendor's public pricing page on September 27, 2026 to October 14, 2026 (date per row). Archive dates come from web.archive.org snapshots: a “Seen” change happened between the linked snapshot and the one before it.

Which Basin alternative is best for each use case?

Each row names the option whose published plan wins that use case on the numbers above. Basin wins several of them.

Basin: spam toolkit and uploads on Free

Basin (usebasin.com) is the baseline here. Free is 50 submissions a month on 1 form with 30-day retention and 100 MB of file storage. Reliable, host-independent, and strong on spam: reCAPTCHA, hCaptcha and Turnstile are on every plan, and spam never counts toward your limit. Paid plans keep accepting submissions past the cap and bill overage.

Paid plans are quoted billed yearly: Starter is $12.50/month ($15 monthly) for 250 submissions on 3 forms, and Growth, the first plan with webhooks, API and Slack, is $24.17/month for 1,000. The trade-off is the small Free plan and that webhooks sit on the second paid tier. Every tier is on our Basin pricing page, and the head-to-head is splitforms vs Basin.

Formcake: a low-cost plan for light volume

Formcake's pricing page links to a free plan without stating its limit. The cheapest paid plan, Personal, is $25/year for 5 forms and 100 submissions a month, with 90 days of retention and one action per form. It suits a small site that needs little volume; the trade-off is that 100 a month is the lowest paid allowance on this page.

Forminit (formerly Getform): free uploads and EU hosting

Getform rebranded to Forminit in January 2026. Free is 100 submissions a month on 1 form, with file uploads on every plan (100 MB of storage on Free, 25 MB per submission). Pro is $19/month, or $190/year, for 5,000 submissions a month and 15 forms, with signed webhooks from there. Its security page says submissions and files are hosted on AWS in Ireland. The trade-off is the single form on Free and a higher paid entry price. See our Getform alternatives comparison.

Formspark: prepaid bundle, no subscription

Formspark sells prepaid submission bundles that do not expire. Free is 250 submissions in total on up to 10 forms; the paid bundle is a one-time $25 (marked down from $50) for 50,000 submissions. Its webhooks are unsigned, per its docs, and there is no monthly replenishing allowance. At full use the bundle works out cheaper than splitforms Annual below roughly 8,000 submissions a month; above that, Annual's $49/year for 15,000 a month costs less per submission. See splitforms vs Formspark.

Formspree: mature, with webhooks on a higher tier

Formspree is the oldest name on this list and well documented. Free is 50 submissions a month with 30 days of history. Personal is $15/month ($10/month billed yearly) for 200, and Professional is $30/month ($20 billed yearly) for 2,000 with webhooks. It includes spam filtering on every plan plus reCAPTCHA and honeypot support. The trade-offs are the same 50-a-month free cap as Basin and webhooks on the second paid tier. See splitforms vs Formspree and the migration guide.

FormSubmit: free email forwarding with no signup

FormSubmit has no account and no API key. Set your form's action to https://formsubmit.co/your@email.com, confirm the first submission from the activation email, and every later submission lands in your inbox. It is free and unlimited, with no paid plans, and supports a _webhook field, reCAPTCHA by default and a _honey field. What you give up is everything beyond email: no dashboard, submissions kept for 30 days and readable through its API 5 times a day, and attachments emailed (10 MB total per submission) but not stored. More in our FormSubmit alternative guide.

Netlify Forms: best if your site stays on Netlify

If your site deploys to Netlify, add a data-netlify="true" attribute and Netlify detects the form at deploy time. Submissions appear in the same dashboard as deploys, with email and outgoing webhook notifications built in. On credit-based plans, which every account created since September 4, 2025 uses, form submissions are free and unlimited; legacy plans keep the older limit of 100 submissions per site per month. The catch is portability: it only works on Netlify-hosted sites, so changing hosts means replacing the form handler. See splitforms vs Netlify Forms.

splitforms: host-independent endpoint, Pro at $5/month

splitforms (the publisher of this page) uses the same contract as Basin: an HTML <form> with an action URL plus one hidden access_key field, so it works on any host. Free includes 500 submissions total, one-time, with no card and no expiry, unlimited forms and email notifications. Spam filtering is rule-based on every plan (honeypot, time trap, rate limits and content scoring) with a spam folder you can review.

Paid plans start with Pro at $5/month for 5,000 submissions a month with HMAC-signed webhooks and file uploads (up to 5 files of 5 MB each per submission). Annual is $49/year for 15,000 a month. A hosted MCP server with 12 tools is on every plan, so AI agents can create forms and read submissions. The trade-offs: no EU data residency, no hosted form pages (splitforms is HTML-first, with a builder that produces a snippet for your own site), and uploads are paid. If you want a hosted survey link, look at Tally or Typeform instead.

Sign up at splitforms.com/login, copy the access key and change one form attribute. More context: best free form backend services.

Static Forms: a bigger monthly free tier

Static Forms is a simple endpoint for static sites. Free is 250 submissions a month with automatic spam filtering, reCAPTCHA v2, email notifications and a 30-day inbox view. Starter is $6/month, or $48/year, for 3,000 a month, and adds unlimited forms, file uploads and webhooks. Pro is $90/year for 25,000 a month. The trade-offs are that uploads, webhooks and extra CAPTCHAs need Starter, uploads are capped at 4.5 MB per file, and new submissions are turned away at the monthly quota. See splitforms vs Static Forms.

Web3Forms: the largest metered monthly free tier

Web3Forms is an access-key endpoint for static sites and landing pages. Free covers 250 submissions a month, unlimited forms and domains, hCaptcha and 30 days of history. Pro is $15/month or $149/year for 10,000. Webhooks, file uploads, the Submissions API and integrations are paid, and a $49/year plan exists only for students, startups and nonprofits. The side-by-side is splitforms vs Web3Forms.

When is splitforms not the right choice?

• You need EU data residency. splitforms hosts data in the US under Standard Contractual Clauses (see the DPA); Forminit says it hosts in Ireland.
• You want a choice of CAPTCHA on every plan. Basin lists reCAPTCHA, hCaptcha and Turnstile on all plans, including Free, and does not count spam toward your limit.
• You need file uploads on a free plan. splitforms uploads are paid; Basin and Forminit each include 100 MB on Free.
• You want a free allowance that resets monthly. splitforms Free is 500 once; Web3Forms and Static Forms give 250 every month.
• Your site is staying on Netlify. Netlify Forms is one attribute and unlimited on credit-based plans.
• You want to pay once and never renew. Formspark's bundle is a one-time purchase.

How do you migrate from Basin?

Moving off Basin is usually a two-line change per form:

1. Sign up at splitforms.com/login and copy your access key.
2. Find your Basin form HTML. The action URL looks like https://usebasin.com/f/abc123.
3. Replace the action URL and add an access_key hidden input.

<form action="https://splitforms.com/api/submit" method="POST">
  <input type="hidden" name="access_key" value="YOUR_ACCESS_KEY" />
  <input type="text"  name="name"    required />
  <input type="email" name="email"   required />
  <textarea           name="message" required></textarea>
  <input type="checkbox" name="botcheck" style="display:none" tabindex="-1" />
  <button type="submit">Send</button>
</form>

Field names carry over unchanged, and Basin's _redirect becomes a hidden redirect field. The request contract is in /docs. Test on staging, deploy, and keep the Basin account for a while as a safety net before cancelling. For a ready-made form, grab the free contact form template, or browse more guides on the blog.
