Building a ai wrapper / llm app with Railway? Let us review it.
Expert code review for ai wrapper / llm apps built with Railway. We fix Railway-specific security gaps, optimize performance, and handle deployment. From $19.
Common Railway issues we find
Real problems from Railway codebases we've reviewed.
Missing health check endpoint
No health check configured, so Railway can't detect when the service is unhealthy and restart it automatically.
Incorrect start command
Running the development server (npm run dev) in production instead of a proper production build and start command.
No persistent storage for databases
SQLite or file-based storage that gets wiped on every deployment because Railway containers are ephemeral.
Missing environment variable configuration
Required environment variables not set in Railway, or development values used in production causing connection failures and API errors.
AI Wrapper / LLM App challenges to solve
Key ai wrapper / llm app concerns that AI-generated code often misses.
API cost management
LLM API calls are expensive. A single unoptimized prompt can cost cents per request — which adds up fast with real users. You need token counting, cost tracking, usage limits per user, and prompt optimization to stay profitable.
Response time variability
LLM responses take 1-30 seconds depending on prompt complexity, model load, and output length. Your UI needs streaming responses, loading states, and timeout handling. Users abandon apps that feel slow.
Error handling for AI responses
The AI model might: return an error, time out, return malformed output, refuse to answer, or hallucinate. Each case needs specific handling. AI tools build the happy path but not the many failure modes.
Prompt injection and security
Users can manipulate your AI's behavior through carefully crafted inputs — making it ignore instructions, reveal system prompts, or produce harmful output. Input sanitization and output validation are essential.
What we check
Key areas we review for Railway ai wrapper / llm app projects.
API key security — LLM API keys stored server-side, never exposed to client
Cost controls — per-user limits, token counting, usage monitoring
Streaming implementation — proper SSE/streaming for LLM responses
Error handling — timeouts, rate limits, model errors, malformed output
