Generated from data/competitive-capabilities.json, which is gathered by
scripts/fetch_competitor_meta.py. Repository facts below were fetched 2026-09-09.
| Repository | apiaryio/dredd |

| Latest release | dredd@14.1.0 |
| Deployment | CLI (Node.js) |
| Audience | (historical) docs-driven HTTP API testing |
What Dredd is good at¶
- Simple docs-as-tests idea
That list is from the evidence file, not from this project's opinion of Dredd. A comparison page that only enumerated the other tool's gaps would be an advertisement, and this project's whole credibility rests on claims a reader can check.
Where it stops¶
- ARCHIVED (verified): no maintenance since 2024; OpenAPI 3.1 unsupported
Protocols¶
Dredd: API Blueprint, OpenAPI 2.0, Swagger
api-verity-lab: OpenAPI 3.0/3.1/3.2, Swagger 2.0, AsyncAPI 2.x/3.x, GraphQL SDL, gRPC (proto and descriptor sets), MCP tool manifests, WSDL 1.1.

The Dredd column is yes / partial / no / unknown from the evidence file,
with no recorded only where the absence is verifiable or the area is clearly
outside that product's documented scope; the legend and the evidence notes are in
the data file. The api-verity-lab column names the command that provides each one,
because that column is not in the evidence file -- it was gathered to describe other
tools -- and an unsourced yes in every row is the thing this project exists to not
do. A test asserts every command named there exists.
Using both¶
Nothing here argues for replacing Dredd. A tool that owns its lane is worth using in it; this project's claim is a different one -- one contract model and one result format across every protocol you speak, including the ones your agents speak.
The full comparison covers every tool at once, and the benchmark is reproducible, including where this project loses.
