01
It works in demos, then breaks in edge cases.
The happy path looks fine, but the real user paths still leak state, break navigation, or fail when data gets messy.
Audit-First Production Rescue
We turn vibe-coded apps into launch-ready products.
Dang Apps helps founders fix the part AI usually leaves unfinished: risky auth, brittle flows, missing tests, shaky deploys, slow backends, and handoffs another engineer can trust.
First paid step: a fixed-price finish-line audit that shows what to refactor, what to rebuild, and what blocks launch right now.
3-5 day audit
Ranked risks and a rescue recommendation.
Fixed-price sprint
Clear scope before implementation starts.
Security + testing + CI/CD
Production hardening, not cosmetic cleanup.
Chicago-based
Hands-on delivery with direct founder involvement.
Buyer Recognition
Your app is probably stuck here.
Most AI-built products are not failing because the idea is bad. They stall because nobody has done the production work that turns a clever prototype into something safe to launch and easy to own.
02
Auth and permissions feel risky.
Role handling, secret storage, and data visibility often ship as assumptions instead of systems you can trust.
03
There are no tests or deploy guardrails.
One quick fix can quietly break something else when there is no reliable way to validate changes before shipping.
04
The backend is slow, messy, or expensive.
Queries grow without discipline, API calls pile up, and the product starts costing more than the traction justifies.
05
Another engineer would struggle to inherit it.
The code may run, but not in a way that makes ownership, onboarding, or future iteration feel safe.
06
You need a decision: refactor or rebuild.
The real cost is not just fixing bugs. It is choosing the shortest path to a product that can survive real usage.
Offers
Productized rescue work, not vague cleanup.
Each engagement is built around a concrete deliverable so you know what you are buying and what changes before the next step.
Finish-Line Audit
Find the real blockers fast.
A short engagement for teams that need a direct answer on what is risky, what is brittle, and whether the app should be refactored or rebuilt.
You get
- Ranked issue list by launch risk
- Architecture and maintainability notes
- Refactor-vs-rebuild recommendation
Security & Reliability Hardening
Fix the trust layer.
For products that are close, but still need safer auth, fewer edge-case failures, and a cleaner path to production.
You get
- Auth, role, and data-safety review
- Critical path bug fixes and test coverage
- Safer deploy and rollback workflow
Performance & Cost Cleanup
Reduce drag before scale makes it worse.
For apps that technically work, but are getting slower, noisier, or more expensive than they should be.
You get
- Query and API bottleneck review
- Performance improvement implementation
- Cost-risk notes and efficiency fixes
Prototype to Production Sprint
Rebuild the parts that cannot be trusted yet.
For teams that need a stronger foundation, clearer architecture, and a codebase another engineer can safely inherit.
You get
- Defined sprint scope with implementation plan
- Production-grade fixes or rebuild work
- Launch handoff with next-step roadmap
Process
A short path from prototype chaos to launch clarity.
The process stays tight on purpose: diagnose quickly, fix the right things, then hand off a product that is easier to own.
01
Get the real diagnosis.
We review the product the way a launch blocker shows up in real life: risky access patterns, brittle flows, weak handoff quality, and gaps in the path to production.
- Ranked launch risks
- Architecture notes
- Rescue recommendation
02
Fix what matters most.
The sprint focuses on the unstable parts first, then tightens the systems that make releases safer: tests, deploy flow, monitoring, and critical-path reliability.
- Implemented fixes
- Tests on critical paths
- Deploy and monitoring upgrades
03
Leave with a product that is easier to own.
You get a clearer operating baseline, documentation for what changed, and an informed next-step plan instead of a vague “should be good now.”
- Documentation and handoff notes
- Follow-up roadmap
- Optional ongoing support
Pricing
Buy the next step, not a vague discovery process.
The first conversation is free. If there is a fit, the next step is a defined offer with clear output and pricing you can understand before the work starts.
Free
For founders who need a quick read on whether the product is a fit for an audit or a larger rescue sprint.
- 30-minute call
- Initial fit and risk read
- Recommended next step
Best First Step
$1,500
For apps that are built, but not trustworthy enough to launch without a real diagnosis and a clear rescue recommendation.
- 3-5 day review window
- Ranked blockers and risk notes
- Audit fee credited toward a rescue sprint
$7,500+
For teams ready to move straight from diagnosis into implementation, hardening, and launch handoff.
- Defined scope before work begins
- Implementation of agreed fixes
- Launch handoff and follow-up plan
What Makes Dang Apps Different
We do not sell speed theater. We sell a safer path to launch.
The point is not that AI helped produce the code quickly. The point is whether the product can survive real users, real changes, and a future engineer inheriting it without guessing.
What You Leave With
Specific outputs, not a vague sense that things got better.
- A ranked view of what actually blocks launch
- Clear guidance on refactor versus rebuild
- Implemented fixes on the highest-risk paths
- Tests, deploy discipline, and stronger production hygiene
- Handoff notes another engineer can work from
Dang Apps is Chicago-based and founder-led. The work stays hands-on, the recommendations stay direct, and the process avoids the bait-and-switch of endless discovery before anything useful gets delivered.
Start Here
Bring the app that feels close, but not safe to launch.
If the product already exists and the last mile looks messy, start with the free assessment call. If there is a fit, the finish-line audit turns the uncertainty into a concrete plan.
