# Powerduck vs Hoppscotch: Which API Debugging Tool?

**Short answer:** Hoppscotch is a fast, free, web-first request tool; Powerduck is a local-first studio that generates the request set from the contract and verifies the responses. The first is centered on the collection you build in the browser; the second is centered on the OpenAPI file in your repo. Choose by what should be the source of truth.

## What Hoppscotch is best at

A quick call in the browser, no install, and a genuinely free tool that can be self-hosted. It is hard to beat for speed and cost when the job is simply to send a request.

## What a contract-first studio adds

| Capability | Hoppscotch | Powerduck |
| --- | --- | --- |
| Center | Collection | OpenAPI contract |
| Requests | Authored | Generated from paths |
| Response verification | Not built in | Checked against spec |
| Offline | Web-focused | Local files |

## The drift problem

A collection is a separate artifact. When the API changes, the collection is updated by hand and can quietly diverge. A generated request set reflects the contract on every save, so it cannot drift.

## The decision rule

Use Hoppscotch for a free, fast, web or self-hosted request tool. Use Powerduck when the contract should drive the requests and the responses should be verified against it.
