Rally
Waitlists that actually convert.
Rally is a waitlist management service for teams who want to gauge interest before they ship. One API call to collect a signup, one dashboard to see who's waiting, and webhooks to act on it instantly.
No more Google Forms dumped into a spreadsheet you forget to check. Rally is the waitlist tool we built for ourselves and decided to productise — because every product launch starts with the same question: is anyone actually interested?
What you get
Everything in the box
A focused first cut, in production today.
Waitlist API
A single POST endpoint to collect signups. Validates emails, deduplicates entries, and returns structured responses.
OpenAPI-documented
Every endpoint is fully documented with OpenAPI. Generate client SDKs in any language, or just read the interactive docs.
Analytics and export
See how many people signed up, which products they care about, and where they came from. Export to CSV when you need it.
Webhook notifications
Get notified in real time when someone joins. Push new signups to Slack, email, or any endpoint you control.
Bring your own UI
Render the signup form however you like — your brand, your interaction model, your stack. Submit entries with one POST and Rally handles dedup, validation, referral codes, and approval workflows behind it.
Auth-ready via Heimdall
When you’re ready to go public, add tenant-scoped auth with Heimdall. The API surface stays the same.
Spin up your first waitlist
Open Rally in the console, give it a name, then POST entries from your own signup form. Five minutes from idea to inbox.
