Your vibe project deserves
to be built for scale.
We don't just review your landing page. We audit your design, architecture, security, GitHub repo, and tell you exactly when your platform will break — before your users find out.

Not a summary. A full senior engineer review.
Not ChatGPT with your URL pasted in. This fetches your live site, reads your GitHub repo, and runs 10 specialist modules — things you cannot prompt your way to.
The Roast
BRUTALLY HONESTComedically savage, evidence-backed feedback on every element. The kind of feedback a senior engineer gives after their 4th coffee.
Category Scorecard
EVIDENCE-BASEDHero Clarity · Trust Signals · Visual Design · Mobile UX · CTA Strength · SEO — each scored 1–10 with specific evidence pulled from your actual page.
Security & Exposed Keys
LAUNCH BLOCKERWe scan your repo for hardcoded API keys, leaked secrets, auth vulnerabilities, SSRF vectors, and OWASP Top 10 issues. If your Stripe key is in a public commit, we’ll find it.
Architecture Review
BUILT TO SCALEWe tell you exactly at what user count your platform breaks — database bottlenecks, API limits, infra ceilings — plus a migration path to 10K users.
Customer Flow
CONVERSION LEAKSSignup friction, time-to-value, empty states, onboarding drop-offs, and pricing page abandonment. We map every place you’re losing users.
Copy-Paste Fix Plan
HIGHEST ROI FIRSTRanked fixes with the exact code or copy change to make. No vague advice. Paste it in. Ship it.
AI Fix Prompts
UNIQUE TO USReady-to-run Claude/Cursor prompts. Drop into your IDE and watch it auto-fix your hero, CTAs, and conversion flows.
90-Day Founder Roadmap
STRATEGICKill switches (stop this now). Growth unlockers (highest-leverage moves you’re ignoring). Competitor teardown vs your top 3 rivals across 5 dimensions.
Competitor Intelligence
HEAD-TO-HEADWe identify your top rivals, fetch their sites, and compare you head-to-head across 7 dimensions. See exactly where you win and where you’re getting beat.
Vibe Score
THE BOTTOM LINEOne weighted score (0–100) combining architecture, landing page, growth, design, security, and customer flow. Your startup’s launch-readiness in a single number.
From vibe-coded
to production-ready.
Cursor, Bolt, Lovable, Claude — you built something real. Now make it worthy of the users coming your way. We bridge the gap between “it works on my machine” and “it handles 100k concurrent users without breaking a sweat.”
- Landing page that actually converts
- Architecture that doesn’t collapse at scale
- Security posture that survives a launch
- GitHub repo a senior engineer would respect
- Clear 90-day path to growth
At how many users will your
platform break?
Most founders find out the hard way. We tell you before your launch goes viral and takes down your server.
We've analyzed 2,400+ projects. Average scale ceiling: 1,247 users.
Under 100 users
SQLite without WAL mode. You're one concurrent write from a locked database.
1,000 – 10,000 users
No connection pooling. Your API server drowns in idle Postgres connections at scale.
10,000 – 100,000 users
No CDN, no edge caching, no rate limiting. One Hacker News post ends your uptime streak.
Most founders discover this the day their server goes down.

“'Manage your tasks better' — wow, groundbreaking. That's the headline equivalent of a restaurant sign that says 'We Serve Food.' Your hero section is working overtime to say absolutely nothing. Meanwhile, social proof is hiding below three scrolls like it's embarrassed to show its face.”
