WEBSITE-DEVELOPMENT / FIND BY GOAL

What AI Tools Do You Actually Need for Web Development?

You can build with Codex without a pile of plugins. Get the project and tests working, then add browser, GitHub, or design access only when needed.

START WITH THE OUTCOME

Choose the outcome first

Core, optional and skip choices come from this vertical's reviewed data.

01

Write and change code

For reading a project, editing code, running commands, and reviewing diffs, Codex and a working development environment are the core setup.

Browser testing and front-end QA

Start with Playwright CLI when you need repeatable user flows, screenshots, or page checks.

GitHub issues, pull requests, and repositories

Check whether git and GitHub CLI cover the daily work before considering GitHub MCP.

Q01

Does this task need browser interaction or page verification?

A dependable project environment matters more than the number of installed tools.

The minimal setup

The core is small: Codex, a project that runs locally, a concise AGENTS.md, and working lint, test, and build commands. That is enough to begin a large share of web-development tasks.

When you need browser interaction, compare the route first. Add only when structured tool calls or a particular agent loop make it a better fit. See the minimal Codex web setup and Playwright MCP vs CLI for the full decision.

Useful combinations without duplicate layers

  • Codex + project tests: the default starting point for coding work.
  • Codex + Playwright CLI: repeatable browser checks and front-end QA.
  • Codex + Playwright MCP: structured browser tools for workflows that need them.
  • GitHub work: try git and gh before adding another GitHub connection.

Do not treat CLI and MCP as two layers that always belong together. If both reach the same system and perform the same actions, keep the simpler route that already works.

Add a tool only when the gap is clear

Consider Figma when the task must read a design file, Context7 when current library documentation is genuinely missing, and a GitHub connection when remote repository data cannot be handled well by existing commands. Read Skill vs MCP before choosing a layer, and use the Codex MCP guide only when you actually need to configure one.
