Quick answer
Formlets - Formlets wins for most builders who need one or a few forms with unlimited responses, while FormKeep wins if you want a cleaner path from a tiny free tier to predictable flat-priced scaling.
How the free tiers compare
These two free tiers solve the same problem in different ways. FormKeep is the tighter starter plan: you get unlimited forms, spam protection, notifications, and a very low submission cap of 50 per month. That makes it good for prototypes or low-volume contact forms, but you will outgrow it fast. Formlets is more generous on raw usage because the free plan allows one published form with unlimited responses and access to 2,000+ integrations, but it is more restrictive on structure since you only get one form. The paid paths diverge too. FormKeep uses simple flat monthly pricing with clear jumps in submission limits. Formlets is billed annually and its pricing is framed around plan tiers tied to form counts, storage, and team accounts, so the monthly numbers are less straightforward even though the free tier is stronger for ongoing response volume.

After you outgrow the free tier
FormKeep uses flat monthly pricing with clear submission tiers, starting at $4.99/month. Formlets uses annual billing with per-unit styled plan tiers, starting at exVat $15/month billed annually. For small teams, FormKeep is cheaper and simpler to budget because the first paid step is low and monthly. Formlets is more generous on the free tier, but once you pay, annual billing and larger plan jumps make costs less flexible as you scale. No usage-rate table was provided, so exact usage-based scenarios cannot be calculated beyond the fixed plan limits.
When to pick each one
Pick FormKeep when…
- You need unlimited forms for a tiny site or several landing pages, even if total submissions stay under 50 per month.
- You want a cheap, predictable upgrade path with flat monthly pricing starting at $4.99/month.
- You care about spam protection, daily notifications, and a hosted form backend more than response volume.
- You expect to scale submissions in clean steps from 1k to 10k to 100k without annual billing commitments.
Pick Formlets when…
- You need one public form that can collect unlimited responses without paying immediately.
- You want access to 2,000+ integrations on the free plan.
- You are building a contact form, survey, or order form and only need one published form at first.
- You prefer a free plan that is more generous on usage but can live with branding and a one-form limit.
- You are comfortable with annual billing once you move up to a paid plan.
Bottom line
For most builders, Formlets is the better free tier if you only need one form and want unlimited responses right away. FormKeep is the better choice if you expect multiple small forms, want a simple monthly upgrade path, or care about keeping the paid jump very low. The key tradeoff is volume versus structure: Formlets gives you more response capacity for free, while FormKeep gives you more form count and a cleaner path once you start paying.
