Pre-launch waitlist tools in 2026, compared

I make Waitlister, one of the tools below. Read this with that in mind.

I wrote it anyway because the roundups I found disagreed with each other on basic facts. Three of them listed three different starting prices for the same product. So where I could check something myself I did, and where I couldn't I say so.

Short version

• Hate subscriptions, fixed launch window: LaunchList
• Want a real free plan, referrals, email tools: Waitlister
• Minimal widget, live in ten minutes, have a budget: GetWaitlist
• Running a contest or sweepstakes: KickoffLabs

The rest is why.

The table

Alphabetical, so the running order isn't an opinion.

Tool	Starting price	Free tier	Referrals	Public API	First-party SDK
GetWaitlist	$15/mo	Closed to new accounts	Yes, $15 plan	Yes, unauthenticated	None found
GrowSurf	$125/mo	14-day trial	Yes, core product	Yes	npm + PyPI
KickoffLabs	$19/mo	Yes, 100 uniques/mo	Yes, plus contests	Yes	None found
LaunchList	$19 one-time	Yes, 100 submissions	Yes, on free tier	None found	None found
Prefinery	$49/mo	14-day trial	Yes	Yes	None found
Viral Loops	$49/mo	14-day trial	Yes, core feature	Yes, 16 endpoints	Unverifiable
Waitlister	$19/mo	Yes, 100 subscribers	Yes, $19 plan	Yes	npm

One note on that free-tier column. Three of these have a free plan rather than a trial: KickoffLabs, LaunchList and Waitlister. The rest give you 14 days and then stop, and GetWaitlist's free tier is closed to accounts created after June 12, 2025. When you're still validating, that difference matters more than the headline price.

The tools

GetWaitlist

The pitch is fast setup. Embed a widget, collect emails, track referrals.

• Pricing: $15/mo Basic, $50/mo Advanced, $250/mo Pro. No free tier for accounts created after June 12, 2025.
• Strongest: simplicity, and an unusual developer surface. The documented API needs no authentication at all. I fetched a live waitlist as JSON with no credentials. Their docs say a much larger authenticated API exists, mostly undocumented, and to ask if you need it.
• Honest weakness: the free tier is closed to new accounts, so the cheapest way in is $15/mo. Sending from your own domain is gated to the $250 plan.

GrowSurf

A referral program tool that people sometimes use as a waitlist.

• Pricing: $125/mo Startup, $314/mo Business, custom above. 14-day trial.
• Strongest: the in-product referral experience. A user's share link is generated the moment they log in, with no separate signup. It also has the most complete developer surface in this list, mine included: an OpenAPI 3.1 spec, official SDKs on npm and PyPI, seven documented webhook events, and an MCP server.
• Honest weakness: it isn't built for pre-launch. No landing page builder, no queue position, no move-up-by-referring mechanic. If you want a viral waitlist for an unlaunched product this is the wrong shape of tool, and the entry plan is several times the cost of the pre-launch options.

KickoffLabs

The contest and sweepstakes specialist. Refer-five-friends-to-win mechanics, points leaderboards, compliant giveaways.

• Pricing: free plan (100 uniques/mo, branded). Hobby $19, Premium $69, Business $145, Enterprise $289, roughly 30% less annually.
• Strongest: contest mechanics and fraud detection. If you want to run a sweepstakes, this is the one. Twelve documented outbound webhook events, with per-plan rate limits published.
• Honest weakness: heavier than a plain waitlist tool. Multi-language means duplicating a campaign per language and translating the strings yourself. Its llms.txt doesn't mention the API, so an agent reading that file first won't find it, though the API itself is documented.

LaunchList

The pitch is the pricing model: pay once, no subscription. For a two or three month launch window that's a better deal than paying monthly forever.

• Pricing: free tier (100 submissions, referrals, fraud detection). One-time per campaign: $19 for 500 submissions, $79 for 10,000, custom above 100,000.
• Strongest: one-time pricing, and a free tier that includes referrals and fraud detection. Embeddable widget for the no-code platforms.
• Honest weakness: fewer features than the subscription tools. No email broadcast system, so bring your own ESP. Simpler hosted pages. And if you want to drive it from code, I could not find an API: their docs sitemap lists thirty-six pages and none of them is an API page. Webhooks exist through a plugin on the Grow plan.

Prefinery

Running since 2007, longer than most of this category has existed. Enterprise SLAs, deep API, many custom fields per subscriber, staged beta rollouts.

• Pricing: $49/mo Lite, $249/mo Essentials, $499/mo Pro month-to-month; $39/$199/$399 billed semiannually. 14-day trial, no free plan.
• Strongest: maturity and flexibility. If you can describe a waitlist mechanic you can probably build it here. Eighteen documented webhook events covering the full tester lifecycle, the most of anyone in this list. Its pricing table is also unusually explicit that API and webhooks are excluded from the entry plan.
• Honest weakness: the interface shows its age and setup is slow. For a founder who wants a good-looking waitlist page and a leaderboard by tonight, it's overkill, and $49 is a steep entry for validating an idea.

Viral Loops

The referral-template platform. Pick a template modeled on a famous launch, add your copy, run it.

• Pricing: billed annually, $35/mo Start-up through $279/mo Power. Month-to-month is higher. 14-day trial, no free plan.
• Strongest: the template library. You start from a mechanic that already worked rather than from zero. Sixteen documented API endpoints with per-endpoint rate limits.
• Honest weakness: no free plan. I also could not verify what's gated to which plan: their pricing page returns 403 to automated requests, and their openapi.json returns 403 rather than 404. There's a @viral-loops/widgets package on npm last published in 2022 with no repository or homepage, and I found no vendor page linking to it, so I won't call it first-party.

Waitlister

Hosted landing pages, embeddable forms, referral program, email broadcasts, custom domains, webhooks and a REST API, plus native embeds for Framer, Webflow, WordPress, Shopify, Squarespace and Bubble among others.

• Pricing: Free (100 subscribers, 1 waitlist). $19 Launch (unlimited subscribers, referrals, 2,500 emails/mo). $29 Pro (custom domain, advanced analytics). $49 Growth (custom email domain, 30+ translations, referral fraud detection). $129 Business (team seats).
• Strongest: the free tier is a plan rather than a trial, and $19 gets you unlimited subscribers, referrals and email broadcasts in one place. Several tools here expect you to bring your own ESP for that last part. On the developer side there's an OpenAPI 3.0.3 spec at waitlister.me/openapi.json, an npm SDK, and an MCP server listed in the official MCP registry. Appending .md to any docs URL returns raw markdown, which is useful if you point an agent at it.
• Honest weakness: It's much younger than some other options. And for a referral program that lives inside your product for years, GrowSurf is the right shape.

How to pick

Start with whether you're validating or launching. If you're validating, pick something with a real free plan so you don't pay for a test that may go nowhere. If you're launching and budget isn't the constraint, the question becomes campaign shape instead.

Then the shape. A pre-launch queue with referrals, a contest, and an ongoing in-product referral program are three different products, and forcing one tool into another's job is what makes people hate their tooling.

Solo founder or small team: start free somewhere and pay when you hit the thing you actually need, whether that's referrals, a custom domain, your own sending domain, or translations. Enterprise, contests, or a long-term referral engine inside your app: pick the specialist.

Everything above is checkable, and some of it will be wrong within a month. If you find something that already is, say so and I'll correct it.
