When Figma raised their prices 60% overnight in 2024, the design community erupted. But Sketch's product team didn't find out for 3 days — by then, dozens of Figma users had already switched. In a market where pricing changes can shift customer behavior overnight, most companies still track competitor prices by... manually checking websites once a quarter.
Prisync ($99-399/mo) serves e-commerce with automated price monitoring and has grown to $2M+ ARR. But they focus exclusively on e-commerce product prices. For SaaS, there's almost nothing. A product manager at a 100-person SaaS company admitted to maintaining a Google Sheet with 15 competitor pricing URLs that she checks 'whenever she remembers' — usually after a prospect says 'your competitor just lowered their price.'
The gap is a horizontal price monitoring tool that works for both SaaS pricing pages and e-commerce products. Scrape daily, detect changes with visual diffing, alert via Slack, and maintain a historical price database. At $19-49/mo (10x cheaper than Prisync), it's an easy expense for any product or pricing team.
💰 Revenue Blueprint
Three-tier value ladder to monetize from day one
Monitor 3 competitor URLs, weekly checks, email alerts only
25 URLs, daily checks, Slack + email alerts, price history charts, visual diff screenshots
Unlimited URLs, hourly checks, API access, CSV/PDF reports, team dashboard, custom alert rules
Why Now?
SaaS companies changing pricing more frequently (usage-based, PLG experiments). E-commerce price wars intensifying. AI makes web scraping more reliable (handles dynamic pricing pages).
📊 Market Evidence
The Market Gap
Prisync ($99+/mo) is e-commerce only. Competitors.app ($19/mo) tracks website changes but not pricing specifically. No tool focuses on SaaS pricing intelligence at affordable rates.

Build a SaaS product called "Competitor Price Monitor". ## Product Overview Track competitor pricing changes automatically and get alerts when they adjust. $19-49/mo. ## Problem SaaS companies change pricing frequently but there's no automated way to track it. Product managers manually screenshot competitor pricing pages quarterly. E-commerce brands need to track hundreds of competitor prices daily. By the time you notice a competitor dropped prices, you've already lost deals. ## Solution Automated price monitoring that scrapes competitor websites daily, detects changes, and sends Slack/email alerts. Historical pricing data, trend charts, and comparison views. ## Target Audience Product managers, pricing teams, e-commerce brands, market researchers ## Tech Stack - Next.js 15 (App Router) with TypeScript - Tailwind CSS v4 for styling - Supabase for auth, database, and storage - Vercel for deployment - shadcn/ui for UI components - Framer Motion for animations ## MVP Features to Build 1. Landing page with clear value proposition 2. User authentication (sign up, sign in, forgot password) 3. Core product functionality based on the solution above 4. Dashboard for users to manage their data 5. Pricing page with at least 2 tiers (free + paid) 6. Basic settings/profile page ## Known Competitors Prisync, Competitors.app, Visualping ## Key Risks to Address Web scraping can be fragile and get blocked Pricing pages vary wildly in structure Prisync could expand beyond e-commerce ## Deployment 1. Set up Supabase project and configure environment variables 2. Deploy to Vercel with `npx vercel --prod` 3. Set up custom domain 4. Configure Supabase RLS policies for security ## Instructions Start by creating the project structure, then build the landing page first. Use server components where possible. Make it mobile-responsive from the start. Focus on getting the core value loop working before adding polish.
