UpgradeWall: SaaS Plan Comparison Page A/B Test Recorder

The Problem

A persistent pain point on r/indiehackers and HN is that founders iterate their pricing page constantly but have no persistent record of what they changed, when, and what the conversion outcome was — so they end up re-testing the same failed ideas months later. UpgradeWall automatically screenshots and diffs a founder's pricing/upgrade page on every deploy, links each version to a date range of Stripe upgrade events, and produces a visual 'what we tried and what happened' audit log. It closes the loop between pricing page experiments and actual revenue outcomes without requiring a full A/B testing platform.

Target Audience

Solo SaaS founders and small teams who iterate their pricing page manually without a formal experimentation stack

Monetization Angle

$12/mo per site; free tier stores last 3 versions, paid stores unlimited history with Stripe correlation

Recommended Tech Stack

Why Now

Stripe's new revenue reporting and the proliferation of no-code pricing page builders mean founders are changing prices more often than ever but have no institutional memory of what they tried.

MVP Scope

A webhook that triggers a Puppeteer screenshot of a URL on each Vercel deploy, stores diffs in a timeline, and shows a side-by-side view of 'before' and 'after' with the date range's upgrade count from Stripe.

AI Angle

AI reads the visual diff between two pricing page versions and writes a one-sentence plain-English summary of what changed (e.g., 'You removed the free tier and added an annual discount badge') to make the audit log scannable.

Primary Risk

Founders may not connect pricing page changes to Stripe data accurately if they use manual coupon codes or sales-assisted upgrades — correlation without causation is a trust risk.

Validation Checklist

• Ask in r/indiehackers: 'Do you keep a changelog of your pricing page changes and their revenue outcomes?' — expect 'no' to dominate
• Search HN for 'pricing page experiment' and count how many threads express regret about not tracking what they changed
• Offer to manually audit 5 founders' Wayback Machine pricing history vs. their MRR chart for free in exchange for feedback
• Build a landing page with a waitlist and post it as a 'Show HN' to gauge developer interest before building the screenshot infrastructure

Who Would Pay For This

Likely buyers are engineering teams, platform leads, developer-experience teams, and technical founders. Start with Solo SaaS founders and small teams who iterate their pricing page manually without a formal experimentation stack and look for teams already spending time or money on this workflow.
