Which one is for you
Pick Basin if
- Fits if you run a static site and need submissions emailed without writing server code
- Works for freelancers and agencies handling several client forms
Look elsewhere if
- 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
Pick OpnForm if
- Fits if you want unlimited submissions with no per-response fees
- Works for developers wiring forms up with webhooks and an API, or teams self-hosting an open-source builder
Look elsewhere if
- Not for you if the branding has to go and you won't pay, since removing it and custom domains need Pro at $25 a month
- Tight if you self-host with a team: the free edition allows 2 users per instance, and more need a $1,999-a-year license
- Skip it if you want to trial the paid features first, because there's no automated trial
- Pricey if you need roles, partial submissions or HubSpot, Salesforce and Airtable, which start at Business at $67
- Watch out: e-signatures aren't on record, free uploads stop at 10 MB, and the AI form builder and analytics are paid
How we grade them

|---|---|---|
| Value for money | BStarter is $12.50 a month billed yearly, inside the cheapest quarter of form tools at $14. It allows 250 submissions and 3 forms. | C$25 a month billed yearly sits right on this category's $24 middle, and that's what removes the branding and adds custom domains, password protection and analytics.

| Free plan and trial | CFree gives 1 form endpoint, 50 submissions a month and 30 days of stored data. | ANo usage wall: unlimited forms and unlimited submissions, with logic, computed fields, webhooks, API access and basic integrations, where most of this category meters responses. The catch is OpnForm's badge, 1 workspace and 10 MB uploads. |
| Features | CIt 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. | BIt covers the whole job: classic or conversational layouts, multi-step forms, logic, validation, computed fields, pre-fills, Stripe payments, password protection, expiry and captcha. E-signatures aren't on record, which several rivals here do have. |
| Ease of use | CNo store rating on record. You paste an endpoint into your own form's HTML, which suits developers more than anyone else. | CNo store rating on record, and a form is a build: fields dragged in, logic and computed fields set up, then publishing.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
