Libretto is an open-source debugging tool that integrates with your Playwright test suite to automatically diagnose failures and propose code fixes. When a test breaks, its AI agent investigates the live page state and opens a GitHub pull request with a concrete solution. It works with any browser provider and leaves your existing test infrastructure unchanged.
Autoblocks AI is a development platform for teams building chatbots and agents who need confidence their AI systems work reliably. It automates test case generation from real user interactions, evaluates AI responses against expert-defined standards, and monitors production systems to catch failures early. Built for regulated industries where AI quality directly impacts trust and compliance.
Escape uses AI agents to discover vulnerabilities, test applications across complex workflows, identify multi-step attack chains, and generate framework-specific fixes. It replaces manual pentesting and legacy security scanners with automated processes, reducing testing from days to hours while handling OAuth, SSO, and multi-tenant scenarios.
Augment Code (Cosmos) deploys specialized AI agents across your software development lifecycle—from deep code reviews and test generation to security vulnerability remediation and incident response. It intelligently routes tasks to optimal models and provides agents only relevant codebase context, reducing token usage and costs. Designed for engineering teams looking to scale productivity without manual review bottlenecks.
Smodin integrates multiple AI writing tools into one workspace: detect AI-generated text, humanize AI output to pass detection systems, check plagiarism, and draft content with AI assistance. Supports over 100 languages and handles text via paste or file upload, serving students and professionals who need to verify, improve, and ensure authenticity in their writing.
Virtuoso QA is an enterprise test automation platform built on AI-first foundations, letting teams write test cases in natural language that execute immediately. The platform features self-healing test locators (95% accuracy) that reduce maintenance overhead, plus multi-platform coverage across web, API, and cross-browser scenarios. Designed for QA teams seeking to accelerate testing cycles while cutting down on flaky test maintenance.
Bugasura is a QA platform built for development teams using AI tools but unwilling to sacrifice quality standards. It ingests requirements and defect histories to build context, deploys specialized testing agents to execute carefully designed cases rather than automating rote checks, and runs them across browsers, APIs, and mobile apps. A free forever plan works for most teams, with optional Testpert AI and enterprise features available.
AskUI automates testing through an AI agent that observes screen content and reasons about actions to execute. Rather than relying on brittle selectors or element IDs, it adapts to UI changes and works across desktop, web, mobile, and embedded interfaces—even systems traditional automation tools cannot reach.
