Fiberplane

Tooling for operating and observing agent systems, from a team that previously built collaborative incident notebooks.

Control plane thinking, applied to agents.

What it is sold for

Building and observing agent-driven software work.

The rest of testing and code quality, alphabetically. Sharing a category is a filing decision, not a relationship.

AICodeSlopMonitor

Scans public repositories and reports how much of the code looks machine-generated.
Amazon CodeGuru Reviewer

Amazon's automated review service. The address now serves CodeGuru Profiler, which is about runtime cost rather than review.
Applitools

Visual regression testing. Compares rendered screenshots rather than the DOM, so a layout that moves is caught even when the markup did not change.
Autify

Test automation aimed at quality teams rather than at engineers, with tests authored and maintained without code.
Beeceptor

Mock API endpoints created in seconds, generated from a prompt or from captured traffic, across REST, GraphQL and gRPC.
BitDive

Records real Java runtime behaviour and turns it into regression tests and review verdicts.
Blackfire.io

Continuous profiling for PHP and other runtimes, aimed at finding the slow function rather than the slow request.
Checksum AI

Generates, runs and maintains end-to-end tests automatically, and claims to resolve most of its own failures.
