TUI Health Monitor for AI Agents: Real-Time Cost & Performance Dashboard¶

AI agent developers burn thousands of dollars on LLM costs without realizing it, lacking real-time visibility into token usage, latency, and spending across multiple providers—leading to budget overruns and performance issues.
App Concept¶
- A beautiful TUI (Terminal User Interface) dashboard inspired by btop/htop for AI agent monitoring
- Real-time tracking of token usage, costs, latency, error rates across OpenAI, Anthropic, Gemini, etc.
- Live graphs showing request patterns, token consumption trends, and cost projections
- Agent-level spend tracking with profit margin calculations for AI SaaS products
- Alerts for cost spikes, budget limits, and performance anomalies
- Works locally with integrations for AgentOps, Langfuse, and custom agents
Core Mechanism¶
- Lightweight SDK integration: 2 lines of code to start monitoring any AI agent
- Real-time metrics collection: captures reasoning traces, tool calls, session state, caching
- Interactive TUI with keyboard shortcuts: navigate between agents, filter by time range, zoom graphs
- Cost attribution: breaks down spending by model, operation type, and agent task
- Performance profiling: latency percentiles (p50, p95, p99), error rate tracking
- Budget enforcement: soft/hard limits with automatic throttling or alerts
- Trace viewer: inspect individual LLM calls with full request/response details
- Export capabilities: CSV, JSON, or direct integration with Grafana/Datadog
- Offline mode: continues monitoring with local SQLite storage when cloud unavailable
Monetization Strategy¶
- Free tier: Single agent monitoring, 7-day data retention, basic metrics
- Pro tier ($19/month): Unlimited agents, 90-day retention, advanced analytics, custom alerts
- Team tier ($79/month): Shared dashboards, team collaboration, role-based access, Slack/Discord alerts
- Enterprise tier ($299/month): On-premise deployment, SSO, custom integrations, dedicated support
- Cloud sync service: Optional paid tier for multi-machine dashboard access
- White-label licensing: Embed monitoring in your AI product ($499/month)
Viral Growth Angle¶
- Shocking cost revelation posts: "Discovered I was spending $847/day on Claude API"
- Beautiful terminal UI screenshots on Twitter/Reddit (aesthetic appeal)
- Cost optimization success stories: "Reduced AI costs by 73% using TUI Health Monitor"
- Integration with popular agent frameworks (CrewAI, AutoGen, LangChain) for automatic discovery
- Live streaming coding sessions showing the dashboard in action
- Open-source repository with "awesome-tui" list inclusion
- Conference demos at AI Engineer Summit, AGI House events
Existing projects¶
- AgentOps - Python SDK for AI agent monitoring with dashboard, 2-line integration
- Langfuse - Open-source LLM observability with latency, cost, and error tracking
- Coralogix AI Cost Tracking - Real-time AI spending visibility
- Paid.ai - Real-time agent spend and profit margin tracking
- Grafana AI Monitoring - Dashboard for agent framework performance
- Helicone - LLM observability platform (web-based, not TUI)
Evaluation Criteria¶
- Emotional Trigger: Limit risk, be prescient (prevent financial disaster, catch problems early)
- Idea Quality: Rank: 7/10 - Growing need as AI agents proliferate + beautiful UX differentiator
- Need Category: Stability & Performance Needs (cost management, reliability monitoring)
- Market Size: 5M+ AI developers/companies using LLMs, estimated $150M+ observability market
- Build Complexity: Medium-High (requires TUI framework, multi-provider API integration, real-time data visualization)
- Time to MVP: 5-6 weeks with AI agents (basic TUI + single provider + cost tracking + alerts)
- Key Differentiator: Only terminal-native AI monitoring tool combining beautiful TUI with comprehensive multi-provider cost and performance tracking
