Product Audit Before Rebuild: Codebase, Architecture & Cost Roadmap
Stop guessing what a rebuild will cost or whether your codebase is salvageable. We inspect your data model, performance bottlenecks, tech debt, and delivery risks — giving you an unvarnished go / no-go and a fixed-price roadmap in 10 business days.
When to Run a Product Audit Before Rebuilding
Rewriting software is expensive. Patching obsolete software is often even more expensive. An audit protects capital by diagnosing the reality of your codebase before anyone touches production.
MVP Stuck After Agency Handoff
An agency built an MVP, but the team left, documentation is non-existent, and every bug fix introduces three regressions. You need to know if the foundation is sound or a liability.
- ✓ Dependency vulnerability check
- ✓ Auth & session safety verification
- ✓ Code quality & maintainability index
Legacy Web App Slowing Down Growth
Your web app generates real revenue ($1M–$50M ARR), but new feature releases take months. Database queries time out, and customers complain about sluggish page loads.
- ✓ Relational schema & index profiling
- ✓ Latency bottleneck identification
- ✓ Zero-downtime cutover planning
Defensible Budget & Cost Estimation
Your executive team or board needs accurate figures before approving capital. You need a defensible web application rebuild cost breakdown rather than agency guesswork.
- ✓ Fixed cost and timeline bands
- ✓ Core vs deferrable scope matrix
- ✓ Executive board-ready technical deck
The 4 Core Audit Inspection Pillars
We don't just run automated linters. Senior product architects perform a hands-on forensic investigation of your full stack.
1. Architecture & Data Model Integrity
We dissect database schemas, foreign key relationships, ORM queries, API response sizes, and cache invalidation strategies to find structural breaking points.
- ✓ N+1 query patterns and missing indices
- ✓ Relational data consistency & migration feasibility
- ✓ API payload sizing and hydration latency
2. Codebase Health & Technical Debt
We measure maintainability, framework obsolescence, third-party dependency vulnerabilities, test coverage, and modularity.
- ✓ Outdated frameworks (legacy AngularJS, PHP, Vue 2, Next pages dir)
- ✓ Unhandled exceptions, dead code paths, and state leakage
- ✓ Type-safety gaps and build tooling inefficiencies
3. Infrastructure, Security & DevOps
Review of deployment pipelines, containerization, environment variable management, role-based access control, and compliance readiness (SOC2 / HIPAA).
- ✓ CI/CD reliability and automated release hygiene
- ✓ Secret management, auth tokens, and session hygiene
- ✓ Cloud hosting cost optimization and scaling ceiling
4. Feature Surface & Salvage Assessment
We separate high-value revenue workflows from dead baggage, identifying which business logic can be ported directly versus what must be rewritten.
- ✓ Core customer monetization flow mapping
- ✓ Salvageable code assets vs rewrite targets
- ✓ Third-party SaaS integration dependency audit
How the 1–2 Week Audit Runs
A low-friction, high-velocity process requiring minimal hours from your team.
Access & Profiling
NDA execution, read-only repository and database schema access, staging environment setup, and baseline telemetry extraction.
Forensic Deep-Dive
Code analysis, database query tracing, third-party dependency review, and interviewing key stakeholders on critical user paths.
Synthesis & Spec
Drafting the technical specification, modeling the build vs rebuild vs patch trade-offs, and calculating fixed-scope cost estimates.
Executive Debrief
Live 60-minute video presentation with leadership, walk-through of the architectural roadmap, and handoff of all deliverables.
What You Receive at Completion
Tangible, executive-ready artifacts that you own outright — whether you build with StillBeacon, another partner, or your internal team.
1. Executive Summary & Go / No-Go Decision
A 3-page executive document for founders, VPs of Product, and board members detailing codebase viability, security liabilities, and immediate operational risks.
2. Build vs. Rebuild vs. Patch Analysis
A transparent, numbers-backed comparison matrix showing the exact ROI, maintenance liabilities, and velocity delta of refactoring vs clean-slate rebuild.
3. Production Architecture Specification
Target tech stack design (Next.js, TypeScript, PostgreSQL, Vercel/AWS), database entity-relationship diagram (ERD), and migration protocols.
4. Fixed-Scope Rebuild Scope & Timeline
A milestone-by-milestone breakdown with cost bands for an 8–12 week production delivery sprint, leaving zero ambiguity on timeline and budget.
Paid Audit vs Traditional Agency Estimates
Traditional agencies give you a "free" quote in 24 hours — designed to win the contract, followed by months of change orders. We take a disciplined engineering approach.
| Evaluation Factor | StillBeacon Product Audit | Typical Agency "Free Estimate" |
|---|---|---|
| Codebase Inspection Depth | Line-by-line repo review, database profiling & auth tracing | Sales rep skim; automated script run at best |
| Cost Transparency | Fixed cost band with risk contingency breakdown | Artificially low bids that balloon via change requests |
| Independence of Advice | Honest go / no-go; won't sell work you don't need | Always recommends a complete rewrite to bill hours |
| Credit Toward Build | 100% of audit cost credited to 8–12 week Rebuild Sprint | No tangible deliverable if you don't hire them |
| Artifact Ownership | Full architectural spec and ERD yours to keep | Proprietary sales deck with zero actionable code spec |
