As answered by people managing Codekru Tools and TestAcademy.dev.
Codekru Tools's answer
CodeKru Tools brings software testing education, hands-on practice, and developer utilities together in one platform.
Unlike traditional learning websites that primarily offer tutorials, CodeKru lets users apply what they learn through interactive coding assignments, execute Selenium automation directly in their browsers, and use AI-powered tools to generate test cases and test scenarios.
The platform includes online Selenium Java and Python compilers, practical assignments for Selenium, Playwright, and API testing, and AI-powered testing utilities.
Our focus is simple: reduce the gap between learning automation and actually using it, without requiring complicated setups or switching between multiple platforms.
TestAcademy.dev's answer:
TestAcademy does more than check if your automated test passes.
You write tests using Playwright, Cypress or Selenium and run them against a working application. Then TestAcademy checks your tests against versions of the application where bugs have been added on purpose.
You can see which bugs your tests caught and which ones they missed.
This helps you understand whether your tests actually check the right behaviour, not just whether they pass.
Codekru Tools's answer
CodeKru Tools is designed for developers and QA engineers who want practical, accessible tools without unnecessary complexity. Instead of just reading tutorials, users can solve real automation challenges, run Selenium scripts directly in their browsers, and get feedback on their solutions. The platform also includes AI-powered test case and scenario generators that help streamline everyday testing activities. What sets CodeKru apart is the combination of structured learning, practical coding exercises, browser-based execution, and AI-assisted testing in one place. Whether you're learning Selenium for the first time or looking to improve your existing testing workflow, CodeKru provides a practical environment to learn, experiment, and build skills.
TestAcademy.dev's answer:
TestAcademy focuses on learning by doing.
You can write and run automated tests directly in your browser without installing anything.
The platform offers hands-on practice problems, Playwright, Cypress and Selenium lessons, QA interview questions, AI mock interviews and a free test code review tool.
You also get feedback on your code and can check whether your tests catch real problems in the practice applications.
You can start for free.
Codekru Tools's answer
CodeKru Tools is primarily built for Software Test Engineers, SDETs, QA Automation Engineers, Software Developers, and students learning test automation.
It serves both beginners who want to learn Selenium, Playwright, and API testing through practical exercises, and experienced professionals looking for convenient browser-based automation tools.
The platform is also useful for QA teams that want to generate test cases, explore testing scenarios, practice automation concepts, and improve their testing workflows.
Our goal is to make modern test automation more accessible to anyone interested in software quality and engineering.
TestAcademy.dev's answer:
TestAcademy is built for people who want to learn or improve their QA automation skills.
This includes beginners, manual testers moving into automation, QA engineers learning Playwright, Cypress or Selenium, and professionals preparing for technical interviews.
It can also help QA leads and hiring teams review how candidates write tests and which bugs their tests detect.
Codekru Tools's answer
CodeKru started from my experience working as a Software Development Engineer in Test (SDET).
After nearly six years in software testing and automation, I noticed a recurring problem: there were plenty of tutorials explaining automation concepts, but relatively few accessible places where engineers could actually practice them.
CodeKru initially started as a technical blog where I shared articles about Selenium, Java, API testing, and automation engineering.
Over time, I wanted to go beyond tutorials and create something more interactive. This led to developing coding assignments, online Selenium compilers, and eventually AI-powered tools for generating test cases and scenarios.
Today, CodeKru is evolving into a comprehensive software testing platform where engineers can learn, practice, execute automation, and access useful developer tools.
I'm building CodeKru with a long-term goal of making practical software testing education and automation tools accessible to developers worldwide.
TestAcademy.dev's answer:
The idea behind TestAcademy is simple: a passing automated test does not always mean the application has been tested properly.
A test might pass even when an important feature is broken.
TestAcademy focuses on solving this problem through hands-on practice. Instead of only teaching how to write tests, it gives learners a way to check whether their tests can catch bugs.
The goal is to help people develop practical QA automation skills they can use in real projects.
TestAcademy.dev's answer:
TestAcademy is built with Next.js, React, TypeScript and Tailwind CSS.
The platform also uses Auth.js for authentication, Upstash Redis for data storage, OpenAI for AI-powered features, Paddle for payments and Vercel for hosting.
For browser testing practice, TestAcademy supports Playwright, Cypress and Selenium.
