Replay is an AI-native QA and time-travel debugging platform for web applications. Replay QA autonomously explores a web app, records every session in a deterministic Replay Browser, finds real bugs, and hands a coding agent the root cause and a suggested fix. The recording is a time-travel database of everything that happened in the browser — sources, console, network, DOM, React renders — inspectable after the fact without reproducing the bug locally. Replay exposes this programmatically through a GraphQL API, a WebSocket Replay Protocol, a published Model Context Protocol (MCP) server for agent debugging, a CLI (replayio), and Playwright/Cypress recording integrations. Backed by a16z and Version One Ventures.
