The three shapes of AI coding tools
Coding CLIs, AI IDEs, and app generators. Decide where you want to read code first, then pick the tool.
- Last reviewed
There are dozens of AI coding tools, but if you sort them by what sits between you and the code, there are only three shapes. Choosing the shape first is far more useful than comparing feature lists.
The three shapes
| Shape | Where you work | Our picks | Good for |
|---|---|---|---|
| Coding CLI | Your terminal and your own editor | Pi | Developers who want full control of context and read diffs |
| Coding IDE | An editor with an agent built in | Cursor, Qoder | Most people who want to collaborate while looking at code |
| App generator | A chat box in the browser | Lovable | Getting a clickable prototype first and worrying about code later |
Coding CLI: the most transparent
A CLI agent does one thing: read files, edit files, run commands. Your editor, Git, and terminal stay yours, so it fits into any workflow and it is easy to see exactly what changed. The trade-off is that there is no GUI safety net; you review changes in the terminal.
Coding IDE: the most comfortable
An IDE puts completion, chat, the agent, and your code in one window. Changes show up as diffs in the file you are already looking at, and accepting or reverting is one click. For people who code a little, this is the shape with the lowest learning curve and the fastest feedback.
App generator: the fastest to a result
Describe what you want and get a deployed web page minutes later. It makes the decisions about project structure, dependencies, and hosting for you. That is why it is fast, and also where it stops: once you need something off its default path, you export the code and continue in a CLI or IDE.
Our recommendation
- Pick one CLI or one IDE as your main tool, and learn it properly. Agent quality depends heavily on the context you give it, and knowing one tool's context features beats switching between several.
- Use generators only to validate ideas. Once you are serious, pull the code out through GitHub.
- Whatever you choose, write an AGENTS.md first. Almost every tool reads it, and you will not have to rewrite it when you switch.
