Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.4
GPA, above 24 of the 60 other form and survey tools we grade
Basin is a hosted form backend: an HTML form's action URL points at a Basin endpoint, and submissions arrive by email, in a dashboard and through webhooks and integrations. It also offers a form generator and AI-generated sites with hosting, and plans are limited by monthly submissions and storage.
To get you started, here are 9 things to know about Basin, taken from its own pages and our grades.
You paste an endpoint into your own form's HTML, which suits developers more than anyone else.
- 1
Best for a form endpoint for a static site
Basin is a hosted form backend: you point a form at its URL and submissions arrive by email, in a dashboard and through integrations.
- 2
Paid plans start at $12.50 a month
As its pricing page puts it: $12.50 per month for 250 submissions, billed yearly ($15 billed monthly).
- 3
There is a free plan

- 4
It runs on Web
Web.
- 5
Point any form at Basin
Set a form's action URL to a Basin endpoint; it works with plain HTML, React, Vue, Webflow, WordPress and other front ends.
- 6
Spam filtering
Basic filtering is on every plan, and spam does not count toward the submission limit. Pro adds advanced, location, language and content filters.
- 7
Notifications and auto-responses
Submissions trigger notification emails, and Growth and above add auto-responses. Pro adds custom email templates and domains.
- 8
A 2.4 GPA, above 24 of 60
That is against the other form and survey tools we grade, on value, the free plan, features, ease of use and platforms.
- 9
Keep it
To replace Basin you would be making connections to other products, each kept working as those products change. That is not a weekend's work, with an AI app builder or without one.

The report card
Best for a form endpoint for a static site
Basin is a hosted form backend: you point a form at its URL and submissions arrive by email, in a dashboard and through integrations. The free plan is 1 endpoint and 50 submissions a month, and webhooks, the API and auto-responses all wait on Growth at $24.17 a month.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | B | Starter is $12.50 a month billed yearly, inside the cheapest quarter of form tools at $14. It allows 250 submissions and 3 forms. |
| Free plan and trial | C | Free gives 1 form endpoint, 50 submissions a month and 30 days of stored data. |
| Features | C | It receives and routes submissions well enough, but it is a backend rather than a form builder, and the page says overage submissions are billed at tier rates. |
| Ease of use | C | No store rating on record. You paste an endpoint into your own form's HTML, which suits developers more than anyone else. |
| Platforms and integrations | B | Web only, with Zapier on every plan and Slack, Sheets, webhooks and an API from Growth. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Basin is for
- Fits if you run a static site and need submissions emailed without writing server code
- Works for freelancers and agencies handling several client forms
Who it is not for
- Tight if you stay on Free, with one form endpoint and 50 submissions a month
- Watch out: webhooks, API access and auto-responses need Growth, and custom email domains need Pro
- Skip it if you want a visual form builder as the main thing, because this is a backend first
- Pricey if your traffic grows, since plans are capped by submissions and extras are billed monthly
Good to know
Good for
- Static and JAMstack sites that need a form endpoint without server code
- Freelancers and agencies running many client forms
- Teams that want submissions sent to Slack, Sheets or webhooks
Worth knowing
- Plans are capped by submissions per month; the page says extra submissions are available at rates made for each tier, billed monthly.
- The Free plan has one form endpoint and keeps data for 30 days.
- Auto-responses, webhooks and API access need Growth; custom email domains need Pro.
- Coupon-code discounts for new customers are shown on some plans and are not counted in these prices.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Basin you would be making connections to other products, each kept working as those products change. That is not a weekend's work, with an AI app builder or without one.
It costs $150 a year.
What you could make
- Forms: an app builder makes this well.
What you could not
- Connections to other products, each kept working as those products change.
- Mail servers with a good name among inbox providers.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. Basin’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
