Questions
Frequently asked questions
Straight answers about what SPARK is, what the dashboard includes—embeds, email workflows, analytics, APIs—and how it fits your launch.
What is SPARK?
SPARK is a pre-launch waitlist product for solofounders and vibecoders. You get a hosted signup page per project so you can measure interest before you commit to a long build.
Who is SPARK for?
Solo founders and vibecoders shipping fast: people validating a concept, collecting signups, and deciding what to build next.
How does a waitlist help before I build?
Signups are a lightweight signal that your pitch resonates. Pair them with dashboard analytics, optional HTTPS webhooks, and welcome email workflows so you can respond to interest without guessing.
What do I get after I sign up?
A dashboard to run one or more apps, each with its own public URL (/app/your-slug). Customize branding and copy—themes, typography, built-in color palettes, corner radii, optional Terms and Privacy links, and social icons—then embed the same waitlist on your site from Branding → Widget. See analytics, filter subscribers by time, export CSV, and use Workflows → Email to welcome new signups via SPARK (SMTP) or Resend (HTML or templates). API keys and signed webhooks connect SPARK to the rest of your stack.
Can I embed the waitlist on my website?
Yes. Branding → Widget provides an iframe snippet you can paste into your landing page, docs, or CMS so visitors sign up without leaving your brand experience.
Do new subscribers get email automatically?
You can turn that on under Workflows → Email: choose SPARK (SMTP) or Resend, write HTML in the dashboard or use a Resend template, send yourself a test email, and new signups receive your message when they join.
Can I connect SPARK to other tools?
Yes. Waitlist API keys power the subscribers API; optional HTTPS webhooks fire when someone joins, with optional HMAC signatures and a delivery log in the dashboard.
Who runs SPARK?
SPARK is operated by Nomadis as part of its product suite. The Terms and Privacy linked in the footer apply.
