AI coding tools

How to choose

Who this is for. Developers and engineering leads choosing an assistant for writing, reviewing, or shipping code — from inline autocomplete in an existing editor to agentic tools that open pull requests on your behalf.

Who this is not for. Non-developers wanting a general-purpose chatbot, or teams needing only documentation search or code hosting. If code must stay on your machines, consider only products with documented local or self-hosted model support; deployment differs by tool.

• Start from where the work happens: a plugin inside your current IDE, an AI-native editor, a terminal agent, or a browser-based app builder.
• Check whether the tool can work on a local repository with diffs, tests, and version control, or only inside a cloud sandbox.
• Note the model policy: some tools lock to one vendor, while others let you bring your own API key or run a local model.
• Confirm licensing, data retention, and whether your private code can be used for training before you adopt a tool for team work.

IDE assistants and autocomplete

Plugins for VS Code, JetBrains, and similar editors that mainly offer completion, chat, and inline edits. Unlike the AI-native editors next, they extend an editor you already use instead of replacing it.

AI-native editors

Editors built around an agent that can edit many files and run project-level tasks. Unlike the plugins above, they replace the editor itself; unlike the terminal tools below, you still work mainly through a graphical editor.

Agentic and command-line tools

Coding agents that edit repositories, run commands or tests, and iterate on tasks through terminal, desktop, IDE-extension or hosted surfaces. Provider and permission options differ. This group describes task-capable workflows rather than ranking interfaces or measuring code quality.

Code quality and AI review

Tools that analyze code — including AI-generated code — for quality, security, and review before merge. Unlike the agentic tools above, they inspect and comment rather than author code; unlike the CI section below, they focus on findings, not on running or fixing the build.

CI/CD and build automation

Continuous-integration and build tooling that adds AI build fixes and review. Unlike the code-quality reviewers above, it sits in the pipeline that runs your builds and tests; unlike the prompt-to-app builders below, it serves existing projects rather than creating new ones.

Prompt-to-app builders

Browser-based tools that turn a description into a working web app, then let you refine it in the same editor. Unlike the pipeline tools above, they generate a new application from scratch, so the starting point is a prompt rather than an existing repository.
