AI Coding Tools Compared: ChatGPT, Claude, Copilot, Cursor, Lovable and AI Agents

July 21, 2025 Alexey Grigorev
ai-tools coding-assistants comparison developer-tools ai-agents

We compare AI coding tools by asking them to help build the same small app: Snake in React. The session is a comparison, not a single production build, so the walkthrough follows the tool categories: chat applications, coding assistants and IDEs, project bootstrappers, and agents.

The comparison

The same app appears in several workflows:

flowchart LR PROMPT["Prompt implement snake in react"] CHAT["Chat apps ChatGPT, Claude, DeepSeek, Ernie, Microsoft Copilot"] IDE["Coding assistants and IDEs Claude Code, GitHub Copilot, Cursor, Pear"] BOOT["Project bootstrappers Bolt, Lovable"] AGENTS["Agents tools, file access, computer use"] CHATAPP["Local app snake-chatgpt"] CLAUDEAPP["Local app snake-claude-code"] PREVIEW["Hosted app Lovable preview"] PROMPT --> CHAT CHAT --> CHATAPP IDE --> CLAUDEAPP BOOT --> PREVIEW AGENTS --> IDE AGENTS --> BOOT

The workshop code includes two Vite React projects. snake-chatgpt keeps the game in one component and is useful for seeing what a chat app can produce from a short prompt. snake-claude-code splits the page shell from the game component, adds score, start and restart flow, WASD controls, and a walls versus pass-through mode.
