Why Simple Signups
A signup backend you can drop into any site — no SDK, no database of your own, and anti-abuse built in.
Most marketing and docs sites need one thing from a backend: accept an email, reject junk, and store the rest somewhere you can export. Building that for every project is a tax — domain allow-lists, rate limits, double opt-in, and a place to keep the data.
Simple Signups is that slice only. One domain-locked endpoint per campaign, spam protection on by default, optional double opt-in, and a dashboard when you want to look — not a CRM you have to live in.
What we optimise for
- HTML-first embed. A plain form POST is enough. No SDK required.
- Abuse resistance. Domain gating, rate limits, and optional Turnstile before a row is written.
- Your data, exportable. Subscribers stay in your campaigns; pull them when you need a list.
Who it is for
Indie hackers and small teams shipping static or lightly dynamic sites who do not want to stand up another database and mail pipeline for a waitlist or newsletter form. If you already run a full marketing automation suite, this is not a replacement — it is the thin intake layer in front of whatever you use next.
This blog will cover product changes, integration patterns, and the anti-abuse choices behind the API as the product matures.
