Essential tools for localhost development and troubleshooting
Enter a port number to get OS-specific commands for checking and resolving port conflicts.
Generate customized commands for your development environment based on your OS, framework, and requirements.
Managing local development environments can be challenging, especially when dealing with multiple projects, frameworks, and services running simultaneously. Our suite of developer tools is designed to simplify common tasks and troubleshoot issues that interrupt your workflow.
One of the most frequent errors developers encounter is EADDRINUSE or "Port already in use". This happens when you try to start a server on a port (like 3000 or 8080) that is already occupied by another process. Our Port Conflict Quick Check tool instantly generates the exact command you need for your operating system (Windows, macOS, or Linux) to identify and terminate the conflicting process. Instead of memorizing complex netstat or lsof flags, you can simply enter the port number and get the solution.
Different frameworks require different commands to start servers, run tests, or build projects. The Development Command Generator helps you standardize your workflow across React, Vue, Angular, Spring Boot, Django, and more. Whether you need to start a server on a specific port, run a production build, or debug a connection, this tool provides the correct syntax for your specific environment.
Development teams often work across different operating systems. A command that works on macOS might fail on Windows Command Prompt or PowerShell. Our tools automatically detect your OS and provide the appropriate commands, ensuring that you can troubleshoot issues regardless of your platform. We support Windows (CMD/PowerShell), macOS (Terminal/Zsh), and Linux (Bash).
