About Replay

Replay is a deterministic browser that records end-to-end tests, allowing developers to reproduce and inspect bugs with perfect accuracy without needing to replicate them locally. This technology eliminates the time-consuming process of debugging flaky tests, significantly improving development efficiency and increasing test pass rates.

Company Description

Problem

Debugging flaky end-to-end tests and reproducing bugs in web applications can be time-consuming and difficult, often requiring developers to replicate the environment and application state locally. The "works on my machine" phenomenon further complicates debugging, as issues may only appear in specific environments or CI/CD pipelines.

Solution

Replay provides a deterministic browser that records end-to-end tests, enabling developers to reproduce and inspect bugs with complete accuracy without local replication. By capturing a comprehensive record of the browser's behavior, including network requests, console logs, and component states, Replay allows developers to "time-travel" and examine the application state at any point during the recording. This eliminates the guesswork involved in debugging flaky tests and facilitates seamless collaboration across engineering teams by providing a shared, reproducible environment. Replay also offers a no-code tool, Nut.new, that integrates with AI code writers to help them debug code by providing clear explanations of the underlying issues.

Features

Deterministic browser environment ensures consistent bug reproduction across different machines and environments.

Built-in test timeline allows developers to step through test executions and inspect application state at each step.

React panel enables inspection of component props and state at any point in time.

Network monitor facilitates identification and analysis of problematic network requests.

Collaborative DevTools enable team members to share recordings and add in-context comments.

Support for Cypress and Playwright test frameworks, as well as other browser automation tools.

Integrations with GitHub, Linear, Loom, and Slack for streamlined workflows.

Source map support ensures accurate debugging of production code.

Target Audience

Replay is designed for software engineers, QA engineers, and front-end developers who need a reliable and efficient way to debug flaky tests, reproduce bugs, and collaborate on complex web applications.
