Haystack by deepset vs. Progress Telerik Fiddler

Haystack is deepset's open-source Python AI orchestration framework for building customizable, production-grade AI agents and workflows. Connect components like language models, vector databases, and file converters into pipelines and agents that retrieve, reason, and act on your own data; use hooks to control the agent loop: enforce a token budget before the next LLM call, incorporate human approval before a risky tool call, or use compaction to keep context small.

Fiddler, backed by Progress, gives you a trusted and secure family of web debugging proxy tools and troubleshooting solutions to address your entire software engineering team's HTTP(s) debugging pain points without any sacrifice. From Fiddler Classic to Fiddler Everywhere, you can quickly get to the root cause of HTTP(S) traffic and network problems and effectively fix them. Easily.
