Depends on your volume, your need for an API, and whether you care how the form looks.
Google Forms is free. Always will be. Unlimited responses. But there's no real API for form creation, no embed control, no webhooks, no custom styling. For internal surveys where appearance doesn't matter, it's hard to beat. But if you need to embed in your product or create forms programmatically, it falls short.
Sutrena's Free plan costs nothing and never expires. Sign up with GitHub or Google. 10 projects (forms, pages, analytics, webhooks, and automations combined), 100 submissions per form, 1 webhook. Everything except CSV export and upsert.
Sutrena Pro is $29/month. 100 projects, unlimited submissions, unlimited webhooks, 5 custom domains, CSV export. No per-response fees. This is the cheapest paid option with a real API, CSV export, and upsert.
Typeform Basic is $25/month for 100 responses. At 1,000 submissions, you're at their $50/month Plus plan. Tally Pro is $29/month. JotForm Bronze is $34/month for 100 monthly submissions.
So for any serious use, Sutrena Pro at $29/month with unlimited submissions is significantly cheaper than any of these.
The cheapest production setup? Sutrena Free ($0) plus Cloudflare Pages (free). Unlimited bandwidth, automatic SSL, global CDN. Total: $0/month for forms, analytics, and a webhook. No server, no database, no Docker. Scale to Pro ($29/month) when you need more.
Scale at $99/month removes all limits. Still cheaper than most competitors' mid-tier plans.
The bottom line: if you need an API, webhooks, and CSV export, Sutrena Pro at $29/month. If you just need a free survey tool and don't care about APIs or embedding, Google Forms costs nothing.
