The best AI coding tools, reviewed and compared
AI coding assistants now range from inline autocomplete to agents that can read your whole repo, open a pull request, and explain their own reasoning. The right pick depends less on raw capability — most of these tools are good — and more on where you want the help: inside your existing editor, in a dedicated AI-first IDE, or as an autonomous agent you hand a task to and walk away from. Below are eight tools we'd actually recommend trying, what each is built for, and how the top picks stack up on price and integration.
GitHub Copilot
Editor pluginInline code completion and chat built into VS Code, JetBrains IDEs, and others. Suggests whole functions based on surrounding context, with a "agent mode" for multi-file edits.
Best for: teams already standardized on a mainstream editor who want AI help without switching tools.
Visit site →Cursor
AI-first IDEA fork of VS Code rebuilt around AI from the ground up — multi-file edits, a built-in agent that can run commands, and codebase-aware chat as the default experience rather than an add-on.
Best for: developers willing to switch editors for a more integrated AI workflow.
Visit site →Claude Code
Terminal agentAnthropic's command-line agent that works directly in your terminal — reads your codebase, makes edits, runs tests, and commits changes, with a Claude in Chrome / desktop app option for non-developers.
Best for: developers who want an agent that lives in the terminal rather than a separate IDE.
Visit site →Sourcegraph Cody
Editor pluginCode assistant built on top of Sourcegraph's code search, so its context window can span an entire large, multi-repo codebase rather than just open files.
Best for: larger engineering orgs with sprawling codebases across many repos.
Visit site →Replit Agent
Cloud IDEDescribe an app in plain language and Replit's agent scaffolds, writes, and deploys it inside the browser — no local setup, hosting included.
Best for: beginners or non-developers building a first project without setting up a local environment.
Visit site →Tabnine
Editor pluginCode completion with a strong focus on privacy — offers fully private, on-prem/VPC deployment options for orgs that can't send code to a third-party cloud.
Best for: regulated industries or companies with strict code-privacy requirements.
Visit site →Windsurf
AI-first IDEAnother from-scratch AI IDE (formerly Codeium), built around a "flows" model that keeps an agent and a human developer working in the same session without losing context.
Best for: developers who want agentic, multi-step coding with more human checkpoints along the way.
Visit site →Amazon Q Developer
Editor pluginAWS's coding assistant, with the deepest native integration for anyone already building on AWS services — including automated upgrades for legacy codebases.
Best for: teams heavily invested in the AWS ecosystem.
