Which AI development tool or plugin should you use?
Compare Codex, Claude Code, Cursor, GitHub Copilot and development plugins by workflow, purpose and setup requirements. These guides use public documentation rather than installation-test scores.
Choose a development assistant, then add plugins for the task
For understanding code, making project changes or running checks, compare assistant entry points and account access first. Skills and MCP extend compatible assistants with task guidance and tool connections; they are not replacements for an assistant.
Operate a page, or investigate a page problem?
Playwright MCP focuses on navigating pages and operating controls and forms. Chrome DevTools MCP also exposes Chrome debugging and performance inspection. Both can operate browsers, so start with the task.
Task instructions, or a tool connection?
Skills supply task guidance, while MCP connects external tools. Identify whether you need a method or access to a tool before choosing.
Look up library docs, or understand existing code?
Context7 supplies library and framework documentation. Serena locates project code through functions, classes and references. They provide different context and can serve different parts of a task.
Before getting started
- Write down one concrete task rather than installing every popular plugin.
- Check your AI assistant, runtime and required permissions.
- Follow project setup guidance, then check the connection with a small task whose result you can verify.
