The best form backend services, compared on real criteria

For most websites: free tier submission limits (how many real inquiries you can receive before paying), spam filtering (so your inbox stays usable), and what happens to a submission after it arrives — does it just email you, or does it become something you can track and follow up on.

Not necessarily. A generous free submission limit with no spam filtering can mean your effective free tier is much smaller once bot traffic is accounted for. Filtering quality matters as much as the raw number.

If the visual design and interaction style of the form itself is the priority — multi-step conversational forms, heavy branding — Typeform's editor is genuinely stronger for that specific job. For a standard contact or lead form where getting organized, actionable submissions matters more than form design, a dedicated backend like FormsToDB fits better.
