Built a ai wrapper / llm app with Manus?
We'll make it production-ready.
AI wrapper apps — products built on top of OpenAI, Anthropic, or other LLM APIs — have unique production challenges. The AI model is a black box that's slow, expensive, and unpredictable. Your app needs to handle variable response times, API failures, cost management, and output quality control in ways that standard web apps don't.
AI Wrapper / LLM App challenges in Manus apps
Building a ai wrapper / llm app with Manus is a great start — but these challenges need attention before launch.
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.
Rate limiting and queuing
LLM APIs have rate limits. When many users make requests simultaneously, you need a queue system to manage the flow and provide feedback to waiting users. Without this, users get API errors during peak usage.
Output quality control
LLM responses aren't deterministic — the same prompt can produce different quality results. You need output validation, retry logic for poor responses, and potentially human review for critical outputs.
What we check in your Manus ai wrapper / llm app
Common Manus issues we fix
Beyond ai wrapper / llm app-specific issues, these are Manus patterns we commonly fix.
Autonomous security decisions without human review
Manus configures authentication, sets file permissions, and chooses security-sensitive patterns autonomously. These decisions are made without context about your threat model and may be inadequate for your use case.
Unknown packages installed without vulnerability audit
Manus installs dependencies autonomously from web research and may choose packages with known CVEs, low maintenance status, or malicious forks. There is no automatic supply chain security check.
Outdated patterns sourced from web research
Manus browses the web to inform implementation decisions. It can pull code patterns, library versions, and architectural approaches from outdated blog posts or Stack Overflow answers.
Compounding errors from autonomous iteration
When Manus encounters errors, it iterates autonomously to fix them. Early wrong decisions get built upon, embedding architectural mistakes that become expensive to unwind.

Frequently asked questions
Can I build a ai wrapper / llm app with Manus?
Manus is a great starting point for a ai wrapper / llm app. It handles the initial scaffolding well, but ai wrapper / llm apps have specific requirements — api cost management and response time variability — that need professional attention before launch.
What issues does Manus leave in ai wrapper / llm apps?
Common issues include: autonomous security decisions without human review, unknown packages installed without vulnerability audit, outdated patterns sourced from web research. For a ai wrapper / llm app specifically, these issues are compounded by the need for api cost management.
How do I make my Manus ai wrapper / llm app production-ready?
Start with our code audit ($19) to get a clear picture of what needs fixing. For most Manus-built ai wrapper / llm apps, the critical path is: security review, then fixing core flow reliability, then deployment. We provide a fixed quote after the audit.
How much does it cost to fix a Manus-built ai wrapper / llm app?
Our code audit is $19 and gives you a complete report of issues. Fixes start at $199 with our Fix & Ship plan. For larger ai wrapper / llm app projects, we provide a custom fixed quote after the audit — no hourly billing.
