Best Debugging Tools for Cursor

DebuggAI is an AI-powered debugging platform designed to streamline the process of identifying and resolving code issues through intelligent automation. It offers features such as text-based test requests, secure local tunneling for testing on localhost servers, and visual test reports with GIF recordings to enhance the debugging experience. The platform supports various technologies, including Node.js, Next.js, React, TypeScript, JavaScript, Python, Django, and Vite, making it versatile for different development environments. DebuggAI aims to reduce the complexity of end-to-end testing by allowing developers to generate and run tests using simple English commands, thereby improving efficiency and confidence in the development workflow.

FlowLens is an AI-native debugging and session-recording tool that captures everything needed for correct, context-aware bug diagnosis and lets AI coding agents fix bugs autonomously. With a simple browser extension and optional MCP server, FlowLens records full user sessions, including video of the UI, network-request data, console logs, user interactions (clicks, inputs, navigation), storage state (cookies, local/session storage), system info, and more, all synchronized on a unified timeline. Once a bug is reproduced, FlowLens bundles that complete context into a single “flow” that can be shared via link. AI coding agents compatible with MCP (such as those from major providers) can then load the flow, inspect network activity, error logs, UI state, and user inputs, and automatically analyze root causes and suggest or even generate code fixes. This removes the need for manual replays, copying and pasting logs, or writing verbose bug descriptions.

BugTape is a hosted error-monitoring and debugging platform for web applications. It collects user-submitted reports, uncaught browser errors, failed or stalled requests, and server-side exceptions, then groups related events into issues. Issues can include DOM-based browser replay (not video), network activity, console output, stack traces, and release context to help developers reproduce failures. Node.js and Python SDKs capture server errors. A Swift package in alpha captures handled errors on iOS and macOS. Teams can triage issues in BugTape or connect an MCP-compatible coding agent to retrieve ranked issues, inspect a reproduction bundle, and report work status with a pull-request reference. When a resolved issue reappears in a later release, BugTape can reopen it as a regression. The service helps development teams investigate problems in web apps and APIs.
