Beyond the Demo. Into Production.

Vibe Coding Gets You
a Demo. We Get You to Production.

Lovable, Bolt, and Cursor are powerful tools — until real users show up. 47% of apps built on these platforms ship with at least one critical security vulnerability.

We build what comes after the prototype: hardened, tested, scalable software that passes investor due diligence and handles production traffic.

The Vibe Coding Problem

AI Writes Working Code.
Not Production-Ready Code.

Tools like Lovable, Bolt.new, and Cursor are genuinely impressive for prototyping. But they optimize for speed and demonstration — not security, scalability, or correctness under load. The gap between "it works on my screen" and "it handles 10,000 real users" is where startups get burned.

/// Platform-Specific Failure Modes

Lovable
CRITICALDatabase authorization gaps

10.3% of deployed apps had missing Row Level Security — any user could read others' data. Highest critical vuln rate: 58%.

Bolt.new
CRITICALHardcoded secrets in frontend

Stripe live keys, DB credentials, and service tokens baked into public JavaScript bundles. 49% critical vuln rate.

Cursor (solo)
HIGHBroken authorization logic

Custom API authorization frequently missing ownership checks — users could access other accounts via BOLA attacks.

Replit
HIGHExposed infrastructure configs

44% critical vulnerability rate. Environment variables and connection strings often accessible in production builds.

V0 / Similar
MEDIUMNo production hardening

UI-first tools generate demos, not deployable services. Error handling, rate limiting, and monitoring absent by default.

How We Ship Differently

Security. Analysis. Testing.
Then We Launch.

Every SandBox Union engagement ships with a production checklist that covers what vibe coding tools skip entirely. Not as an afterthought — as a standard part of the build.

Security Hardening

  • OWASP Top 10 threat modeling on every build
  • Row Level Security on all database tables
  • Secrets managed via environment vaults — never in code
  • Auth flows with token rotation, rate limiting, and brute-force protection
  • Dependency audit (npm audit, Snyk) before every release

Code Analysis

  • Static analysis on every pull request (ESLint, TypeScript strict mode)
  • Security-focused code review by senior engineers
  • Cyclomatic complexity checks — no spaghetti by default
  • Architecture review against your growth roadmap
  • SQL injection, XSS, and CSRF review before each release

QA & Testing

  • Unit + integration test suites with >80% coverage targets
  • End-to-end testing with Playwright for critical user flows
  • Load testing before launch (we find your breaking point first)
  • Regression testing on every deploy — no silent regressions
  • Edge case and error boundary coverage — not just happy paths

Production Prep

  • CI/CD pipelines with automated test gates — bad code can't ship
  • Observability: structured logging, error tracking, uptime monitoring
  • Database migration strategies with rollback plans
  • Environment parity: dev, staging, and production match
  • Runbooks and incident playbooks before you flip the switch

Technical Specifications

/// SYSTEM_CAPABILITIES

Clean Architecture

Modular, typed, and documented. Built to be handed over to your internal team when you scale.

True Scalability

Architected for millions of requests, not just your first 100 users. AWS/GCP ready.

Day 1 Security

SOC 2 ready infrastructure, encryption at rest, and enterprise-grade auth flows.

100% IP Ownership

No vendor lock-in. You own the repo, the CI/CD pipelines, and every line of code.

High Performance

Sub-100ms latency targets. Optimized databases and edge caching standard.

Investor-Ready Stack

React, Node, Python, Postgres. The modern stack that passes technical due diligence.

How We Actually Ship

/// DEPLOYMENT_SEQUENCE

PHASE 01

Architecture

System design, threat modeling, and schema planning before a line is written

PHASE 02

Secure Build

Backend, API, and auth implementation — with OWASP and security review baked in

PHASE 03

Test & QA

Automated test suites, load testing, and end-to-end coverage before staging

PHASE 04

Production Launch

CI/CD gates, monitoring, observability, and runbooks — then we ship

Already Have a Vibe-Coded App?

We offer production readiness audits — we'll assess your existing codebase for security gaps, scalability risks, and what it would take to make it investor and enterprise ready.

Or start fresh. We'll build it right the first time.
