Comparison

Inlet vs Formspree

Formspree is a popular hosted form endpoint for static sites. Inlet solves the same problem — forms without a backend — but self-hosted, multi-tenant, and white-label.

Fair note: Formspree is great for a single site with a single form and zero infrastructure.

The verdict

If you run one site, Formspree is a fine default. If you build and manage many sites — agencies, freelancers, studios — Inlet centralizes every lead in one dashboard you own, with each client seeing their own brand.
