Overview
- Ship AI-built apps with real test coverage by giving Replay QA a URL to autonomously explore the app, write Playwright tests, and record every session with deterministic recording.
- Eliminate manual bug triage when Replay QA files detailed bug reports that include a root cause diagnosis, a specific suggested fix, and a full time-travel debugging recording with runtime evidence.
- Unblock pull requests instantly as Replay QA posts root cause analysis, failure traces, and suggested fixes directly on GitHub PRs, so teams resolve issues without lengthy debugging.
- Integrate autonomous QA into existing workflows by pushing bug reports from Replay QA into Linear or Clickup via the API and MCP, keeping your team aligned without context switching.
- Enable coding agents to fix bugs autonomously by invoking Replay QA through its REST API, which delivers the full content needed for the agent to apply the suggested fix.
- Catch bugs before users do with time-travel debugging data that traces every function call, DOM mutation, network request, and state change, providing an evidence trail for every failure.

❓ Frequently Asked Questions
Replay CI Agent is an AI tool designed to identify and analyze end-to-end (E2E) automated test failures. Upon a test failure, the agent records the entire test run, uses time-travel debugging data to examine the failure, and subsequently posts an insightful analysis on your GitHub Pull Request (PR), including the root cause of the failure, a failure trace, and a suggested fix.
Replay CI Agent uses time-travel debugging data to analyze E2E test failures. It records the entire test run upon a failure, traces the exact sequence of events that led to the failure, provides a root cause analysis, a failure trace and a suggested fix which is then posted on the GitHub PR.
Time-travel debugging data in Replay CI Agent is the recorded data capturing the entire sequence of events during a test run. This data allows the agent to trace the precise sequence of events that led to a test failure. It's an integral part of the tool's mechanism, enabling it to conduct a detailed examination of failures and offer insightful fixes.
The purpose of deterministic recordings in Replay CI Agent is to capture the actual execution of the program which includes render chains, state flow, network timing, JavaScript execution, and DOM mutations. This allows the agent to inspect the full range of components in a web application, enabling it to thoroughly understand the sequence of events leading to a test failure.
Individuals can use Replay CI Agent via Replay MCP by leveraging its time-travel data in their Integrated Development Environment (IDE). This aids in their bug fixing efforts, providing them with detailed failure sequences, an evidence trail citing runtime data, and possible solutions, enhancing their debugging proficiency.
Replay CI Agent helps reduce time spent troubleshooting by providing accurate, AI-driven analyses of test failures, root causes, failure traces, and suggested fixes. By posting detailed analyses directly on GitHub Pull Requests, it eliminates hours usually spent by developers on debugging, thus unblocking PRs and expediting the overall software development process.
Replay CI Agent can inspect a comprehensive range of web application components. These include render chains, state flow, network timings, JavaScript executions, and Document Object Model (DOM) mutations. This extensive insight enables a thorough understanding of the event sequences leading up to a failure.
Replay CI Agent has unique features that include deterministic recordings of the actual program execution, not merely screenshots or logs. This enables it to trace the exact sequence of events that led to a failure. Additionally, it posts an analysis containing the root cause, failure trace, and a suggested fix directly onto a GitHub PR, thereby aiding immediate attention and resolution.
Replay CI Agent provides detailed root cause analysis reports by conducting an exhaustive examination of test failures using time-travel debugging data. It identifies the exact sequence of events that led to the problem, offers a comprehensive failure trace, and provides a suggested solution. These details are then posted on the GitHub PR for immediate action.
Yes, Replay CI Agent can work directly on your GitHub PR. Upon identifying and analyzing a test failure, it posts a detailed examination, including the root cause, a failure trace, and a suggested fix directly on the respective PR. This enables your team to address and resolve the issues promptly.
Replay CI Agent uses recorded data extensively in its analysis. The tool records every function call, DOM mutation, network request, and state change during each test run. This deterministic recording of events forms the bedrock for the AI's ability to conduct in-depth diagnostic analyses, produce a detailed root cause, and suggest corrective measures.
Replay CI Agent reads the actual execution of the program. This includes not merely the error messages, but every component of the program execution like render chains, state flow, network timings, JavaScript executions, and Document Object Model (DOM) mutations.
Replay CI Agent ensures deterministic recordings by capturing every detail of each test run. Rather than relying on screenshots or logs, it records the actual execution of the program.
