Respan is an engineering platform for teams building and deploying AI agents. It provides observability tools that capture prompts, tool calls, and responses from production traffic to help developers visualize execution paths for debugging.
The platform is designed for engineers and product teams who need to manage AI behavior as models update or prompts change. It includes a unified gateway that supports over 500 models, which may help reduce the complexity of managing multiple LLM providers.
Users can run evaluation workflows that combine human review, code checks, and LLM judges. The platform also provides version control for prompts and workflows, allowing teams to test changes against baselines before deploying to production.
Buyers should confirm their expected volume of logs and scores, as the free Pro tier has specific limits and the Team tier is billed annually.
Key Features
Captures prompts, tool calls, and responses from production traffic to trace execution paths.
Supports combining human review, code checks, and LLM judges to measure quality against defined metrics.
Provides a single endpoint to route and deploy across more than 500 models.
Includes version control and a playground to test and compare prompt versions against product data.
Includes custom dashboards with over 80 graph types and alerts via Slack, email, or text.
Allows users to open production traces in a playground to replay behavior and test fixes.
Use Cases
Searching and filtering execution traces to identify where an agent's behavior shifted in production.
Running evaluation flows using human and AI judges to validate response quality.
Tracking changes to prompts and tools and comparing new versions against prior baselines.
Using a single gateway to manage routing and provider abstraction for various LLMs.
