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.
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
10.3% of deployed apps had missing Row Level Security — any user could read others' data. Highest critical vuln rate: 58%.
Stripe live keys, DB credentials, and service tokens baked into public JavaScript bundles. 49% critical vuln rate.
Custom API authorization frequently missing ownership checks — users could access other accounts via BOLA attacks.
44% critical vulnerability rate. Environment variables and connection strings often accessible in production builds.
UI-first tools generate demos, not deployable services. Error handling, rate limiting, and monitoring absent by default.

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
Architecture
System design, threat modeling, and schema planning before a line is written
Secure Build
Backend, API, and auth implementation — with OWASP and security review baked in
Test & QA
Automated test suites, load testing, and end-to-end coverage before staging
Production Launch
CI/CD gates, monitoring, observability, and runbooks — then we ship

Custom Engineering vs. Vibe-Coded Platforms
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.
