GitHub CopilotBest overall for most developers
Works in VS Code, Visual Studio, JetBrains, Xcode and Eclipse, has a free plan with agent mode, and costs $10 for Pro; individual plans now train on your data unless you opt out.
An AI coding tool is software that writes, edits and reviews code from natural-language instructions. These AI coding tools reviews compare nine of them, from GitHub Copilot at $10 a month to app builders such as Lovable, on models, agent features, editors, usage limits and what happens to your code.
Works in VS Code, Visual Studio, JetBrains, Xcode and Eclipse, has a free plan with agent mode, and costs $10 for Pro; individual plans now train on your data unless you opt out.
Included in every ChatGPT plan from Free to Enterprise, with published 5-hour limits, an open-source CLI and network-off sandbox defaults; OpenAI models only.
Runs Claude Opus 5.5, 1st on LMArena WebDev, with subagents, hooks and cloud routines; needs at least Claude Pro and states limits as multiples.
Models from seven makers plus Composer 2.5, Tab, parallel and cloud agents and Bugbot, with SOC 2 and ISO 27001; included usage is not published.
AI Assistant and the Junie agent with BYOK and local models, opt-in data sharing on paid licences, and AI Pro included in the All Products Pack.
Windsurf, renamed Devin Desktop in June 2026, hands tasks from the editor to Devin's cloud agent; its current docs publish no training or retention terms.
Chat-to-app building with Lovable Cloud, security scans on every publish, and SSO plus default training exclusion on Business; credit use per message varies.
Replit Agent builds inside a full coding workspace with hosting, 15 collaborators and 28-day database rollback on Pro; effort-based billing is hard to predict.
1 million free tokens a month and $25 Pro with 10 million tokens, running entirely in the browser; models and training policy are not disclosed.

There are two kinds, built for two different people. Assistants for developers, such as GitHub Copilot, Cursor, Claude Code and OpenAI Codex, work inside your editor or terminal. They complete code as you type, answer questions about the repository and run agents that edit many files, run tests and open pull requests. App builders for non-developers, such as Lovable, Replit and Bolt.new, turn a chat description into a hosted web app with a database.
The line keeps blurring. Every developer tool now ships an agent, and every builder lets you see the code. What still differs is the model, the usage you get for the money, and who can read your code.
The default for working developers is GitHub Copilot. It runs in VS Code, Visual Studio, JetBrains, Xcode and Eclipse, has a free plan with agent mode, and Pro costs $10 a month. Switch when one of these is true:
| Tool | Cheapest paid plan | Where it runs | Training on your code |
|---|---|---|---|
| GitHub Copilot | Pro $10/mo | VS Code, Visual Studio, JetBrains, Xcode, Eclipse, CLI | On by default for individuals since April 24, 2026 |
| OpenAI Codex | ChatGPT Go $8/mo | CLI, VS Code and JetBrains extensions, ChatGPT app | Consumer plans train by default |
| Claude Code | Claude Pro $20/mo ($17 billed yearly) | CLI, VS Code, JetBrains, desktop, web | Consumer setting; never on Team or API |
| Cursor | Pro $20/mo | Cursor editor, CLI, JetBrains plugin | None with Privacy Mode on |
| Lovable | Pro $25/mo ($250/yr) | Browser | Opt-out on Free and Pro; excluded on Business |
Skip the upgrade if you code a few hours a week. Copilot Free includes agent mode, and Codex already sits inside ChatGPT Free. Don’t use an app builder for a product that will handle payments or personal data unless a developer reviews the code. Builders produce working apps quickly. Nobody guarantees they are secure.
Most people miss the billing change. Three shifts matter.
Every score is a research score. We use official pricing and docs, independent leaderboards and security advisories, and we label vendor benchmarks as vendor claims. We don’t present a vendor’s numbers as our own findings.
Three tools sit within 0.1 of each other: OpenAI Codex and Claude Code at 8.7, Cursor at 8.6. In practice, the per-criterion lines decide between them. Claude Code scores 9.3 for models but 7.5 for price and limits, because Anthropic states limits as multiples rather than numbers. Codex has a full home in our ChatGPT review. For chat-first help, see AI assistants, part of our AI tools section. Anthropic documents what Claude Code keeps in its data usage policy.
Every product here is scored 0 to 10 on the same criteria, using published evidence. The overall score is the weighted average.
GitHub Copilot, on our evidence. It scores 8.8, works in five major editor families plus the command line, includes agent mode on its free plan and costs $10 a month for Pro. If you've already paid for ChatGPT, try Codex first, since it is included with every ChatGPT plan.
Yes, several. GitHub Copilot Free includes agent mode, Codex works on ChatGPT Free, and JetBrains has an AI Free tier. Bolt.new gives 1 million free tokens a month for browser prototypes. Free plans cap usage. When you run long agent sessions, expect to hit those caps.
Some do unless you opt out. GitHub Copilot's individual plans have trained on your data by default since April 24, 2026. Claude Code follows your consumer privacy setting but never trains on Team, Enterprise or API use, and Cursor trains on nothing with Privacy Mode on. Business plans usually exclude your code by default.
Yes, with app builders such as Lovable, Replit and Bolt.new, which turn a chat description into a hosted web app. They work well for prototypes and internal tools. For anything that takes payments or stores personal data, have a developer review the code and security settings before launch.
