Introducing WaitStack: the waitlist platform that doesn't charge you monthly to store emails

Let's be honest: most waitlist tools are glorified email collectors charging you £29/month for the privilege of storing a few thousand rows in a database. We thought that was ridiculous. So we built WaitStack.

What is WaitStack?

WaitStack is a developer-first waitlist platform designed for indie hackers, startups, and anyone launching a new product. It handles everything you need to validate ideas and build hype before launch—without the enterprise complexity or recurring fees that drain your runway.

We give you viral referral mechanics, AI-powered lead scoring, fraud protection, and a full headless API. Use our embeddable widgets or build your own UI. Your call.

Why we built it

We've launched products before. Every time, we'd cobble together some combination of Airtable, Mailchimp, and custom scripts to manage our waitlist. Or we'd pay for a SaaS tool that charged monthly for features we'd only need for a few weeks pre-launch.

Stop paying monthly for a database of emails. That's the core principle behind WaitStack. You're launching a product, not signing up for a lifetime subscription to waitlist software.

We wanted something that was simple to integrate, powerful enough to grow virally, and priced in a way that made sense for bootstrapped builders. So we made it ourselves.

Core features

Built-in referrals

Your users do the marketing. Every person who joins your waitlist gets a unique referral link. When they share it and someone signs up, they climb the queue. This isn't a gimmick—it's how Dropbox and Robinhood built massive pre-launch audiences. We've baked it into the platform from day one.

AI-powered lead scoring

Not all signups are equal. Our AI scoring analyses each lead based on engagement, referral activity, and behaviour patterns. You'll know who's genuinely interested versus who signed up and forgot about you. Prioritise the right people when you launch.

Fraud protection

Viral mechanics attract bad actors. We've built in detection for fake referrals, duplicate signups, and bot submissions. Your waitlist stays clean without you having to manually review it.

Full API

Full API. Build your own UI or use ours. WaitStack is headless by design. Embed our widgets if you want something quick, or integrate via API if you're building a custom experience. We don't lock you into our frontend.

One-time pricing

One-time pricing. Buy once, own forever. No monthly fees. No usage limits that suddenly spike your bill. Pay once, use it for as many launches as you want. We think software should work like this more often.

Who is WaitStack for?

If you're building something and want to validate interest before writing a single line of code (or after writing thousands), WaitStack is for you. Specifically:

• Indie hackers launching side projects and MVPs

• Startup founders building hype before a product launch

• Developers who want an API-first solution they can customise

• Creators launching courses, communities, or digital products

If you've ever paid £300/year to store 2,000 email addresses in someone else's database, you're exactly who we built this for.

What WaitStack isn't

We're not trying to be an all-in-one marketing suite. We don't do email campaigns, CRM, or twelve other features you'll never use. WaitStack does one thing well: helps you build and manage a waitlist that grows itself.

We're also not enterprise software. If you need SOC 2 compliance, dedicated account managers, and quarterly business reviews, we're probably not your tool. We're built for people who ship fast and don't have time for sales calls.
