Respan AI
Route, track, and debug all LLM traffic.
What is Respan AI?
Respan AI is a tool for managing and monitoring large language model traffic across your applications. It sits between your application and LLM APIs, allowing you to route requests, track usage, and identify issues in real time. The tool is designed for developers and teams building with LLMs who need visibility into what's happening with their model calls. It captures request and response data, making it easier to debug problems, optimise prompts, and understand how your LLM integration is performing. Since it's available as a free tier, it's accessible for small projects, startups, and teams evaluating their LLM infrastructure.
Key Features
Request routing
Direct LLM traffic through Respan to control which models and endpoints requests go to
Request and response tracking
View logs of all LLM calls including prompts, responses, and metadata
Debugging tools
Identify errors and issues in LLM requests and responses with detailed error reporting
Usage monitoring
Track token consumption and API costs across your LLM calls
Multi-model support
Work with different LLM providers and models from a single interface
Pros & Cons
Advantages
- Free to start with, making it accessible for development and testing
- Centralised view of all LLM traffic helps identify problems quickly
- Reduces time spent debugging by showing exactly what requests and responses look like
- Useful for understanding costs and optimising which models you use
Limitations
- Requires integration into your application stack, so not zero-setup
- Limited information available about free tier limitations compared to paid options
Use Cases
Debugging LLM integration issues in development environments
Monitoring token usage and costs for cost-conscious teams
