Read the verdictTypeform
Typeform's signature conversational interface genuinely outperforms traditional multi-field forms on engagement, but you pay for it: the free plan caps at just 10 responses per month, and the entry paid tier costs $28/month (billed annually) for 100 responses. Response limits are hard walls—when you hit your cap, the form closes and turns visitors away. For solo founders running lean, that's expensive per-lead pricing unless conversion quality justifies the premium.
Tally
Tally's free tier is legitimately generous: unlimited responses, conditional logic, Stripe payments, signatures, and file uploads are all included within fair-use guidelines. The Notion-like block editor is fast for simple forms but offers less visual layout control. Pro at $29/month (month-to-month) adds branding removal and custom domains. If you're pre-revenue or testing product-market fit, Tally removes the financial friction entirely.
Fillout
Fillout positions between Tally's unlimited-free model and Typeform's premium pricing. The free plan includes 1,000 responses per month with unlimited forms—enough runway for most early-stage founders. Where it shines is workflow automation: native Airtable/Notion syncing, scheduling, payment collection, and multi-step logic without needing Zapier. Starter at $15/month (annual) is the cheapest path to branding removal and custom domains among the three.
