TLDR
A fake door test needs three things: a pricing section with real CTAs, click-level tracking (not just page views), and a waitlist redirect. No single commercial tool is purpose-built for this. Validea includes it as a first-class feature. The DIY path is any landing page builder plus a custom click handler writing to a database. The Stripe route (pre-orders) is the strongest signal but adds legal obligations. Choose based on how much signal you need and what you're willing to build.
Validea
Built-in FakeDoorPricing component tied to Cloudflare D1. Shows three pricing tiers, tracks clicks with tier name and timestamp to the database, redirects to a waitlist page.
Pros
- ✓ Click tracking to D1 database built in — no custom code required
- ✓ Tracks tier name, page source, and timestamp per click automatically
- ✓ Redirects to waitlist page after click, configured in site.ts
- ✓ Deployed to Cloudflare free tier, no tracking cost at validation stage
Cons
- × Tied to the Validea scaffold — not a standalone embeddable widget
- × Early access, not yet production-stable
Pricing: $9/mo Starter, $29/mo Pro, $79/mo Agency
Verdict: Best if you want fake-door pricing tracking without building it yourself. Deploy the scaffold, configure your tiers, and the tracking is wired automatically.
Stripe Checkout (Pre-Orders)
Collect real payment as the ultimate fake door signal. Set up a product with a pre-order price, embed a Stripe checkout link, and see who actually pays.
Pros
- ✓ Payment is the strongest possible demand signal — harder to game than a click
- ✓ Stripe handles payment processing, tax, and receipts
- ✓ Free to set up; Stripe takes 2.9% + $0.30 per transaction
- ✓ Works as a button on any landing page (Carrd, Webflow, custom site)
Cons
- × Legal obligation to deliver or refund — creates real accountability
- × Most visitors won't pre-pay without significant social proof and polish
- × Stripe is a payment processor, not a validation analytics tool — you need to track click-through rates separately
Pricing: Free setup, 2.9% + $0.30 per transaction
Verdict: Best for the hardest possible validation signal on a polished product with a clear value proposition. Combine with a real landing page. Not the right first step for a rough idea test.
Tally.so (Embedded Form as Fake Door)
Free form builder. Can be used as a lightweight fake door: 'Get Early Access' button opens a Tally form that collects intent and email.
Pros
- ✓ Free tier with unlimited forms and responses
- ✓ Embeds cleanly into Webflow, Carrd, or custom sites
- ✓ No-code setup, form live in minutes
- ✓ Can add a pricing question to the form to gauge willingness to pay
Cons
- × A form is not the same as a fake pricing tier click — lower commitment signal
- × No click tracking per pricing tier, just form submissions
- × No automatic redirect flow after form submission without paid plan
Pricing: Free, $29/mo Pro
Verdict: Useful for collecting qualified intent when you don't have a pricing page yet. The 'what would you pay?' question in a form is lower-signal than a pricing tier click but better than nothing.
PostHog (Click Tracking + Custom Pricing Page)
Open-source product analytics. Track custom events on your pricing page manually — requires a developer to instrument the click handlers.
Pros
- ✓ Free tier with 1M events/month
- ✓ Custom event tracking gives you per-tier click data
- ✓ Session replay shows how visitors interact with the pricing section
- ✓ Works on any custom landing page
Cons
- × Requires a developer to add event tracking code to the pricing page
- × No built-in pricing tier component or waitlist redirect — must build both
- × More setup than a purpose-built solution
Pricing: Free up to 1M events/month, then usage-based
Verdict: Best for indie hackers who want analytics depth on a custom pricing page and are comfortable adding a few lines of JavaScript. Pairs well with any landing page that has a custom pricing section.
Hotjar (Heatmaps + Click Tracking)
Session recording and heatmap tool. Can track clicks on pricing CTAs via click maps without custom event code.
Pros
- ✓ Heatmaps show exactly where visitors click on the pricing section
- ✓ Free tier available (35 daily sessions)
- ✓ Session recordings let you watch real visitors interact with your fake door
Cons
- × No per-tier click database — heatmaps are visual, not structured data
- × Can't distinguish which tier someone clicked in raw data exports easily
- × Free tier (35 sessions/day) may not capture enough volume early on
Pricing: Free (35 sessions/day), $32/mo Plus
Verdict: Useful as a complement to structured click tracking. Heatmaps tell you whether visitors are reaching the pricing section at all. Use alongside PostHog or Validea's D1 tracking for full picture.
Q&A
What is the best tool for fake door testing?
Depends on what you can build and what signal you need. For no-code, zero-build fake door pricing with automatic D1 tracking: Validea. For the strongest possible signal (real payment): Stripe pre-orders on any landing page. For tracking clicks on a custom pricing page without a backend: PostHog free tier. For a quick intent form without building a pricing page: Tally.so.
Q&A
How do you track pricing tier clicks without a backend?
PostHog's free tier lets you track custom events with two lines of JavaScript: posthog.capture('pricing_click', {tier: 'pro'}) on each button click. You get structured event data without running your own database. The trade-off is you're trusting PostHog's event capture (which samples at scale) and the per-tier breakdown requires setting up a funnel in PostHog's UI.
What Makes a Good Fake Door Test
A fake door test puts a pricing page in front of potential customers before the product exists. The visitor sees real pricing tiers, clicks a plan, and lands on a waitlist instead of a checkout flow. The click is the signal. If nobody clicks the paid tier, the idea has a demand problem.
The tools below range from zero-code solutions to custom instrumentation. The right choice depends on how much you can build and what level of signal you need.
The Trade-Off: Signal Strength vs. Setup Effort
Stripe pre-orders give the strongest signal (someone actually paid), but create legal obligations and require a polished page. Click tracking on a fake pricing page is the sweet spot for early validation: low friction to set up, structured data to analyze, and no refund obligations. Form-based approaches (Tally) are the fastest to deploy but produce weaker signal since filling out a form is lower commitment than clicking a specific pricing tier.
When to Graduate From Fake Door Testing
Once you have 100+ pricing section visitors and a tier click rate above 5%, the fake door has done its job. The next step is discovery interviews with the people who clicked. If you are below 2% after 200+ visitors, the positioning or pricing needs work before you build anything.
