Bash Automated Testing System

MockServer is an HTTP(S) mock server and proxy for testing that lets you mock APIs, inspect and modify live traffic, and inject failures. It supports HTTP/1.1, HTTP/2, gRPC, WebSockets, TCP and more on a single port, with additional support for HTTP/3, message brokers, and AI/LLM APIs.

QA Wolf from anywhere — your terminal, your CI, your AI agent.

My own notes (drafts mostly) about software quality

open source test management system with over 2 million downloads!

Hercules is the world’s first open-source testing agent, enabling UI, API, Security, Accessibility, and Visual validations – all without code or maintenance. Automate testing effortlessly and let Hercules handle the heavy lifting! ⚡

Self-hosted iOS & Android simulator streaming for the whole team

BDD testing with Playwright runner

DeepfakeHTTP is a web server that uses HTTP dumps as a source for responses.

High-performance, multi-protocol mock server. HTTP, WebSocket, gRPC, MQTT, SSE, GraphQL, SOAP in one binary.

🤖 Repeat tests. Repeat tests. Repeat tests.

Model-driven synthetic test data for CI/CD and analytics - deterministic, privacy-preserving, and domain-aware. Includes Python APIs, XML pipelines, and MCP/IDE integration to orchestrate realistic datasets for finance, healthcare, and other regulated environments.

An agent-native QA CLI for web pages. Deterministic, no tests to write, no LLM.

Interview Test using a To Do List

Test harness for voice agents. Import from Retell, VAPI, Bland, LiveKit. Run autonomous simulations. Evaluate with LLM judges.

AI-Drived end-to-end test platform

The Swagger Coverage Tool is designed to measure API test coverage based on Swagger documentation. It provides automated tracking and reporting of test coverage for APIs, helping ensure that your endpoints and services are well-tested.

Ultimate tool to measure gRPC service coverage from tests

UI Coverage Tool is an innovative, no-overhead solution for tracking and visualizing UI test coverage — directly on your actual application, not static snapshots.

An open-source mobile app explicitly designed as a QA automation training playground.

Standalone MCP tools for browser scanning, page inspection, and Playwright reproduction. Local workflow with no QualityMax account required.

Assertions for non-deterministic AI text. Drop into pytest, get a Trust Score + HTML report. Free-first: rules, local embeddings, then your own LLM judge.

Vision-enabled AI steps for Playwright tests. Bring your own LLM: OpenAI, Claude, Gemini or TestChimp.
