Reviewing Generated Code
The AI models VULK uses, what they build best, and a review checklist for taking a generated app to production.
Reviewing Generated Code
VULK generates typed projects that follow modern patterns. Before you take an app to production, run it through the same review you would give any code your team ships.
Review checklist
- Review generated code before using it in production
- Test all functionality end to end, including forms, auth and payments
- Validate security for apps that handle sensitive data
- Check edge cases for your domain: empty states, invalid input, large data sets
- Confirm domain rules — calculations, legal and medical content — with a qualified reviewer
Available AI Models
| Model | Best For |
|---|---|
| Gemini 3.1 Pro | Default full-stack generation and design fidelity |
| Claude Opus 4.8 | Architecture and complex business logic |
| Claude Sonnet 4.6 | Careful edits and refactors |
| GPT-5.5 | Strong all-rounder |
| DeepSeek V3.2 | Cost-effective code generation |
All paid plans have access to the hosted model lineup. BYOM is available on Pro, Team, Max, and Business.
What VULK Builds Best
- Standard UI components
- Common patterns (forms, lists, cards)
- Responsive layouts
- CRUD operations
- Popular framework conventions
Getting the Most from Complex Features
For custom business logic, complex state, real-time features (WebSockets), advanced animations and niche library integrations:
- Describe the rules precisely — inputs, outputs and the cases that matter
- Build in steps — one feature per message, then test it in the preview
- Choose a model for the job — see Choosing a Model
- Ask for tests — request unit tests for calculations and business rules
Generated Code
Generated code:
- Uses TypeScript
- Follows modern patterns and framework conventions
- Is yours to optimize, extend and refactor
Using generated code is covered by the Terms of Service.
