As answered by people managing CatchForm.dev and Sentry.io.
CatchForm.dev's answer
CatchForm is deliberately not a form builder. Your HTML defines the fields — whatever your form posts is what gets stored — so adding a field means editing your own markup, not reconfiguring anything here.
Two defaults are unusual. Notifications only go to an address you have confirmed by clicking a link sent to it, so an endpoint cannot be pointed at a stranger's mailbox. And redirects after submit are restricted to the host you set in your form's settings, so the endpoint cannot be used to bounce visitors to somewhere else.
Submissions are stored independently of email. If a notification bounces or lands in spam, the message is still in your inbox here.
CatchForm.dev's answer
Because it is not tied to where your site is hosted. The same form works on Netlify, Vercel, Cloudflare Pages, GitHub Pages, S3 or your own server, and keeps working when you move between them.
The free plan is meant to be used on a real site rather than to expire: one form, 100 submissions a month, no card. Pro is $12/month or $120/year for 10 forms, 10,000 submissions a month, file uploads and webhooks.
It is built and supported by one developer. Support, billing and bug reports go to one address and are answered by the person who wrote the code — there is no ticket queue to navigate.
CatchForm.dev's answer
Developers and small web studios building static sites — Astro, Hugo, Eleventy, Jekyll, or hand-written HTML — where there is no server to process a contact form and adding one is out of proportion to the need.
Typically a portfolio, a landing page, documentation, or a small business site with a contact or enquiry form. People who want the form to work, not a form product to learn.
CatchForm.dev's answer
CatchForm grew out of a set of small tools built by one developer in Bishkek, Kyrgyzstan. The form backend was the one with demand that never goes away: every static site eventually needs a contact form, and every time it means either standing up a server for a single POST or pasting a mailto: link that quietly loses messages.
It launched publicly on catchform.dev in 2026. It stays deliberately small — one job, done properly, rather than a form builder that grows features until it needs a manual.
