# Show HN: Reticle – Postman for AI Agents

## TL;DR

- Reticle is a local desktop tool (Tauri + React + SQLite) that consolidates the full LLM agent testing loop into one interface.

---

## Summary

- Reticle is a local desktop tool (Tauri + React + SQLite) that consolidates the full LLM agent testing loop into one interface.
- You define scenarios with prompts, variables, and tools, run them against multiple models, and see prompts, responses, tool calls, and results in one view.
- An eval mode checks whether a prompt or model change silently breaks existing behavior – essentially regression testing for AI agents.
- All data stays local: prompts, API keys, and run history are stored in SQLite on your own machine.
- A step-by-step view for agent runs shows exactly why a model made a specific decision.

## Nauti's Take

The Postman analogy is well-chosen and hits a real nerve – tooling for agent development is still lagging far behind the pace at which people are actually building agents. The fact that everything runs locally is not a limitation but a hard requirement for many companies. The interesting question is whether Reticle can evolve from a useful solo tool into something teams share – collaborative eval sets and shared scenarios would be the logical next step. For now: a solid approach worth watching.
