Stably

Stably is a cutting-edge, AI-powered testing platform designed to revolutionize the quality assurance (QA) process for modern web applications. It empowers engineering and development teams to ship products faster and with greater confidence by automating the detection of bugs. Stably's core innovation lies in its use of sophisticated AI agents that can navigate and test applications just like a human user would, but with the speed and scalability of a machine. This approach significantly reduces the time and engineering resources traditionally spent on writing and maintaining brittle test scripts.

The platform is built for speed and efficiency, allowing teams to create robust tests 5-10x faster than with conventional methods. It caters to both technical and non-technical users by offering multiple ways to generate tests: writing instructions in plain English, recording user actions in a virtual machine, or for advanced cases, writing custom code. This flexibility ensures that everyone, from product managers to senior engineers, can contribute to a comprehensive testing strategy.

How to use Stably

Getting started with Stably is designed to be a straightforward process that integrates smoothly into existing development workflows. Users can have their first test running in under five minutes.

1. Create Tests with Ease: The primary method is to describe the test you want to run in plain English. For example, you could instruct the AI to "Fill the onboard form for my tech startup" and provide the necessary details. Alternatively, you can use the browser extension to record a user flow, and Stably will automatically convert it into an editable test.

2. Run Tests on Demand or in CI/CD: Once created, tests can be executed on a schedule, triggered manually, or, most powerfully, integrated directly into your CI/CD pipeline (e.g., GitHub Actions). This ensures that every new code commit is automatically vetted for regressions and bugs before it reaches production. Stably is built to scale, supporting thousands of parallel test executions.

3. Leverage AI Auto-Maintenance: One of Stably's standout features is its self-healing capability. When your application's UI changes (e.g., button text, element IDs), traditional tests break. Stably's AI understands the context and intent of the test, automatically adapting to these changes and updating the test steps, saving teams countless hours of maintenance work.

4. Integrate and Collaborate: Stably tests can be version-controlled with Git, syncing them with your feature branches. This keeps your tests aligned with your codebase, making collaboration seamless for the entire team.

Core Features of Stably

• AI-Powered Test Generation: Create tests using natural language commands, screen recording, or code.
• Self-Healing Tests: AI automatically maintains and updates tests when your UI changes, dramatically reducing flakiness and maintenance overhead.
• Complex Action Handling: Effortlessly tests tricky functionalities like drag-and-drop, file uploads, iframes, multi-tab workflows, and email verification.
• Comprehensive Verification: The AI can verify any element on the page, including text, images, tables, dynamic content, and form states.
• Human-Level Reasoning: Trained on vast datasets of edge cases and complex user flows, the AI can handle scenarios that are difficult for traditional automation.
• App-Specific Learning: Stably learns from your app's documentation, past tests, and code to become progressively smarter and more accurate at testing your specific product.
• Seamless CI/CD and Git Integration: Integrates with GitHub Actions and other CI/CD tools, with full support for version control via Git.
• High Scalability and Reliability: Engineered to scale from a single test to over 10,000 concurrent tests without compromising performance or reliability.

Use Cases for Stably

Stably is ideal for fast-moving companies that prioritize both development speed and application quality.

• End-to-End (E2E) Testing: Automate complete user journeys, such as user registration, onboarding, shopping cart and checkout processes, and profile management.
• Regression Testing: Run a comprehensive suite of tests with every new release to ensure that new features haven't broken existing functionality.
• CI/CD Automation: Embed automated QA directly into the development pipeline to catch bugs early and prevent them from ever reaching production users.
• No-Code/Low-Code Testing: Empower non-developers, like product managers and manual QA testers, to create and manage automated tests without writing a single line of code.
• Testing Complex Web Apps: Perfect for applications with dynamic content, third-party integrations (like Google OAuth), and security measures like Cloudflare bot detection.

Advantages of Stably

Stably offers a significant competitive edge over traditional testing tools and general-purpose AI models.

• Accelerated Development Cycles: By automating the QA bottleneck, teams can release features and fixes much faster.
• Reduced Costs: Frees up expensive engineering resources from the tedious task of test maintenance.
• Superior Reliability: AI-driven self-healing eliminates the flaky tests that plague traditional automation frameworks.
• Democratized Testing: The intuitive, plain-English interface makes it possible for the entire team to contribute to quality assurance.
• Specialized AI: Stably's AI is specifically trained on proprietary QA datasets, allowing it to outperform generic models in browsing, extraction, and assertion tasks.

Pricing and Plans

Stably offers flexible, usage-based pricing designed to scale with your needs, along with a 14-day free trial to get started.

• Starter Plan: $39/month. Ideal for startups and small teams to cover core user flows. Includes up to 8 parallel test executions, 40,000 cached Playwright actions, and 2,000 AI actions.
• Growth Plan: $249/month. Designed for growing companies with expanding features. Includes everything in Starter, plus unlimited parallel test executions, 200,000 cached Playwright actions, 20,000 AI actions, and dedicated Slack support.
