Basin vs. Slapform: What's best for me?

Great question! We obviously think we’re pretty great, but here’s an honest answer - the sticker price doesn’t always tell the whole story. To help you chose the right form backend provider, let’s look at some key similarities and differences.

Both products allow you to setup and manage HTML forms. Both give you a submission archive, file uploads, Zapier integration, data export, and white label features like custom redirects and custom email templates. Ultimately, the best product choice comes down to what’s most important for your own use case.

If you’re looking for a developer-friendly solution that makes it easy to manage forms across projects, has top notch customer support, and is affordable whether you’re just starting out or scaling your business, then we built Basin just for you.

If you don't need to organize forms by project, monitor form performance metrics, or route emails through your own domain, and just need a basic form backend, then we encourage you to give both products a try and decide for yourself!

Another thing to consider is what your needs will be a few months, or even a year from today. If you’re just starting out, both Basin's Standard plan and Slapform's Sumo plan (billed monthly) give you all the core features you need. In that case, you'll spend $1 /mo more by choosing Basin at $12 /mo and also get premium email deliverability, custom branded emails, and API access. However, if you choose Slapform, you won't have access to many of the features we provide even if you upgrade to their $29 /mo Grandmaster plan. Meanwhile, Basin's Premium plan, which includes all of our product features, costs only $36 /mo and gives you everything you need to build your forms your way for less.
