Open Source Testing & Quality Assurance Software
Testing & Quality Assurance software provides environments for verifying code stability and detecting regressions in user interfaces and APIs. These tools automate the process of checking for visual changes and validating response data from backend services. This type of software is for developers and QA engineers who need to track performance metrics and manage test collections. Using self-hostable options allows you to store API requests on local filesystems for version control and run benchmarks on your own hardware without relying on external cloud services.
This page lists 5 open source tools in the Testing & Quality Assurance category. The most popular are Bruno, LostPixel and Hercules. Most use the MIT or AGPL-3.0 license, and 5 offer an official Docker image.
Bruno
An offline API client that stores collections on the local filesystem for version control via Git.
LostPixel
Detects UI changes through visual regression testing for Storybook, Ladle, Histoire, and modern frontend application pages.
Hercules
An AI testing agent that converts Gherkin steps into automated end to end web and API tests.
Bencher
Continuous benchmarking platform that tracks performance metrics on bare metal hardware locally and in CI.
Argos
A visual testing platform that automates UI regression detection to maintain consistent interfaces across engineering teams.
