Basin vs Fillout (2026): which should you pick?

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 Fillout if

• Fits if your whole team needs to edit forms and you don't want to pay per seat
• Works for intake forms that send answers to Airtable, Notion or Google Sheets

Look elsewhere if

• Tight if you stay free: 1,000 responses a month, and every form shows a Fillout badge
• Pricey if you want no branding ($40 Pro) or your own domain, analytics and partial submissions ($75 Business)
• Watch out: uploaded files stop at 20 MB each below Business, and paying monthly lifts Starter from $180 to $228 a year
• Not for you if you need SSO or audit logs (Enterprise) or granular permissions, which come with the $300-a-month Team bundle
• Skip it if you want a phone or desktop app, as Fillout runs on the web only
