LinkFlow - QR + Short Links with Predictive Click Insights

Every time you share a link (Slack, email, social, SMS), get a private analytics dashboard showing who clicked, when, where, and a prediction of how many more clicks you'll get in the next 24h based on historical patterns.

Difficulty

beginner

Overview

Content creators, marketers, and sales teams share links constantly but have zero visibility into which ones convert until days later. They use Bitly for shortening and Mixpanel for analytics, but the two don't talk to each other, and neither predicts future engagement. LinkFlow solves this: create a short link or QR code, share it, and instantly see a live dashboard with clicks, geography, devices, and a real-time prediction ('This link will get 347 more clicks in the next 24h based on current pattern'). The prediction engine uses simple exponential moving average (no ML required) to forecast engagement without being creepy. Why 100% buildable right now: tinyurl API handles shortening, QR code generation is a library (qrcode.react), analytics is just database queries on timestamps, and prediction is basic time-series math. Stripe billing, Supabase postgres for click logs, Resend for emails when a campaign hits milestones. Ship in 12 days.

Business Model

SaaS subscription with monthly plans

Required Skills

Basic Next.js, SQL queries for analytics, time-series math.

Resources

Supabase docs, qrcode.react docs, Stripe billing docs.

Monetization Path

Free tier: 5 links, 30-day history. Starter: $19/month (unlimited links, 90-day history). Pro: $49/month (team access, custom domain, webhook integrations).

Competition Level

High

Estimated Monthly Cost

Supabase: $25, Vercel: $20, Stripe fees: ~$120 (at $2k MRR), Resend: $20. Total: ~$185/month at launch.

Revenue Potential

$19/month × 150 users = $2,850 MRR at month 3. $49/month × 300 users = $14,700 MRR at month 6.

Build It Right

Core User Journey

Sign up -> paste URL -> get short link and QR code -> share -> check dashboard in 1 hour -> see prediction -> upgrade to monthly.

Success Definition

A paying user creates 10 links, receives accurate predictions for 8 of them, uses one prediction to optimize a campaign, and renews the subscription.

Architecture Pattern

User creates link -> short code generated -> stored in Postgres -> user shares link -> click received at API -> click logged with timestamp, geo, device -> prediction recalculated every 30 minutes -> email sent on milestone.

Integration Points

Supabase for link/click storage, Stripe for payments, Resend for milestone emails, QR code library (qrcode.react), optional Slack bot for alerts.

Data Model

User has many Links. Link has many Clicks. Click has timestamp, geo, device, referrer. User has one Subscription (start_date, plan_type).

Avoid These Pitfalls

Do not build complex predictive models — EMA works fine. Do not track IP addresses (GDPR violation) — use geolocation API. Do not store raw click data forever; prune after 90 days on free tier. Do not over-feature on day 1 — just get the prediction right.

V1 Scope Boundaries

V1 excludes: team collaboration, team accounts, API access, Slack bot, custom domain support, advanced segmentation.

Example Use Case

Jamie, a YouTuber, shares 3 links in a video description. Within 5 minutes, LinkFlow shows 45 clicks on link A, 12 on B, 3 on C. The dashboard predicts A will hit 500 clicks by tomorrow morning. Jamie reprioritizes and features A in the video thumbnail next upload. By isolating high-engagement links early, she increases conversion by 40%.

Challenges

Prediction accuracy depends on click velocity — new links with 2 clicks can't predict reliably. Need conservative confidence intervals.

Success Metrics

Week 1: 300 signups. Week 2: 40 paying users. Month 2: 50k links created, 2M clicks tracked.

MVP Scope

Landing page, link creation form, analytics dashboard with live click counter, prediction calculation (simple exponential MA), QR code display, Stripe checkout, Supabase schema for links and clicks. 6 core pages.

Launch & Validation Plan

Survey 30 content creators and marketers about link sharing pain. Build landing page. Recruit 10 beta testers who share 20+ links/month. Validate pricing by asking if they'd pay $19/month for predictions.

Customer Acquisition Strategy

First customer: Post in r/content_creators, r/marketing, and r/Entrepreneur with free beta access offer ('Create 50 links, no credit card'). DM 20 creators on Twitter/X who post affiliate links with personalized demo. Ongoing: ProductHunt, LinkedIn content about affiliate link optimization, TikTok/YouTube shorts about hidden link insights.

Competitive Advantage

Built-in prediction (Bitly doesn't have this), QR code generation native, simple UI, real-time analytics.
