Best AI tools for coding
AI coding tools range from autocomplete inside your editor to agents that plan changes across a whole repository and run tests on their own. Pick by where you work (IDE, terminal or browser), how much autonomy you want, and whether you need to use your own model keys.
Claude Code is Anthropic's AI coding agent, currently at CLI version 2.1.314 (October 2026), with Claude Opus 5.5 as the default model. It runs across the terminal, VS Code, JetBrains, a desktop app and the web, and can drive cloud agents, subagents and computer use.
GitHub Copilot is an agentic, multi-model coding assistant that goes beyond autocomplete, offering chat, an agent mode, cloud agents, code review and a CLI, with models available from vendors including Anthropic, OpenAI, Google, xAI, Microsoft and Moonshot. It bills usage through GitHub AI Credits, with tiers running from a free plan up to individual and organization plans.
OpenAI Codex is OpenAI's coding agent that writes, fixes, refactors and reviews code from the ChatGPT apps, the open-source Codex CLI, an IDE extension and Codex cloud. It is included in ChatGPT plans, with full access starting at Plus for $20 a month.
Cursor is an AI-first code editor built on VS Code with agentic coding, multi-repo support, parallel agents, and automated PR review. New customers now sign up through The X Subscription, a bundle that pairs Cursor with Grok from xAI and X Premium, while other third-party models are billed separately at API price.
Replit Agent 4 runs parallel agents that build authentication, database, backend, and frontend components simultaneously, and includes a Security Agent that scans codebases for vulnerabilities. A newer Monitoring Agent can investigate production issues from app logs and metrics and attempt validated fixes.
OpenCode
Open-source coding agent from Anomaly, available as a terminal interface, desktop app, and IDE extension, supporting 75+ LLM providers via Models.dev — the core agent is free to use with your own API keys or a supported subscription login.
AI coding IDE formerly known as Windsurf, rebranded to Devin Desktop on June 2, 2026 after Cognition and Windsurf came together. Its agent picker includes Devin Local, Codex, Claude Agent, OpenCode and Cascade, with SWE-2 as the current in-house model.
Cline
Open-source autonomous coding agent, available as a VS Code extension, JetBrains plugin, CLI, and native desktop app, that creates files, runs terminal commands, and controls browsers — all with step-by-step user approval. Works with any LLM via your own API key or Cline's own inference provider.
Kiro is AWS's agentic development platform built around spec-driven development, producing structured requirements, design and task specs before writing code. It now spans an IDE (a VS Code fork), a CLI, a web app, and a mobile app, and supports multiple model providers including Anthropic, OpenAI, DeepSeek, and Qwen with an Auto mode that picks a model per task.
Bolt builds full-stack web apps from a prompt — bundled database, auth, storage, edge functions and hosting, no third-party services. It automatically routes each generation task to the right underlying AI model.
v0 by Vercel is an AI-driven, full-stack development platform. After its February 2026 relaunch it moved beyond generating React/Tailwind UI components to building, running, and deploying complete apps, with Git integration and an in-browser editor.
Open-source terminal AI pair programmer that auto-commits every change to git, builds a repo map of large codebases, and supports any LLM. 44,000+ GitHub stars and 6.8 million PyPI installs.
Zed is a code editor built in Rust; its 1.0 release (April 29, 2026) introduced Parallel Agents, letting multiple AI agents work on different parts of a codebase at once. It offers a capped free Personal plan alongside paid Pro and Business tiers.
