GitHub Copilot

GitHub Copilot is one of the most popular AI coding assistants, developed by GitHub. It integrates directly into editors such as Visual Studio Code, Visual Studio and several JetBrains IDEs, offering real-time code suggestions as you type.

Pros: natural code suggestions, smooth integration into existing workflows, support for many languages and a tight link to the GitHub ecosystem. Cons: compared with AI-centered tools, its grasp of the full context of a large project still has a gap, and suggestion quality depends on how clear the surrounding code is.

Cursor

Cursor is a code editor built with AI at its core, developed by Anysphere. Rather than simply adding suggestion features to an existing editor, Cursor redesigns the experience so developers can instruct the AI to edit multiple files at once, explore the codebase and make changes across a broad context. Cursor keeps its name and domain, now under new ownership: SpaceX announced a 60 billion USD acquisition of Anysphere on 16 June 2026 and the deal closed on 14 August 2026. The Pro plan costs 20 USD per month.

Pros: the ability to work across an entire project, multi-file editing and conversational interaction inside the editor. Cons: because it is a separate IDE, users need time to migrate from familiar tools and learn its way of working, and the pending change of ownership is worth watching if you are planning a long-term commitment.

Devin Desktop (formerly Windsurf)

Devin Desktop is the AI-integrated development environment that was known as Windsurf until 2 June 2026. Cognition acquired the product on 14 July 2025 and folded it into the Devin brand; windsurf.com now redirects to devin.ai/desktop, and the tool itself continues to operate. It is notable for its agentic approach, allowing the AI to autonomously carry out a sequence of steps to complete a request, which reduces the number of manual interventions during code generation and editing. The Pro plan is 20 USD per month, an increase from the 15 USD charged under the old name.

One naming quirk survives the rebrand: the JetBrains plugin is still published as “Windsurf for JetBrains”. If you search for the tool and land on old Windsurf documentation, tutorials or forum threads, they generally describe the same product under its previous name.

Pros: highly automated workflows suited to tasks that require several consecutive steps. Cons: the rename is recent, so third-party guides, screenshots and community answers still refer to Windsurf, which makes searching for help more confusing than it should be.

Claude

Claude is an AI model developed by Anthropic, well regarded for its ability to reason over long stretches of code and explain logic clearly. Many developers use Claude to analyze architecture, refactor code, review for bugs and write technical documentation.

Pros: strong long-context handling, thorough explanations and a safety-oriented approach when working with complex code. Cons: to use it directly inside an editor, users typically go through integration tools or an API rather than a ready-made editor.

ChatGPT (GPT)

ChatGPT, based on OpenAI’s GPT models, is a versatile conversational AI tool widely used by the developer community. Users can ask questions, request code generation, debug, or learn a new concept through natural conversation.

Pros: high flexibility, a large community, support for many programming languages and suitability for learning. Cons: because it is not tightly bound to the editor, users must copy code back and forth between the chat window and their project, which can interrupt the workflow.

Gemini

Gemini is Google’s family of AI models, integrated across many services and development tools within the Google ecosystem. Gemini’s strengths lie in handling large context and connecting with familiar cloud services.

Pros: convenient integration with Google products and the ability to work with large amounts of context. Cons: its dedicated coding experience is still maturing compared with some earlier tools.

How far can you get for free?

Every tool here offers a free tier, and for occasional work a free plan often covers the job. GitHub Copilot’s free plan allows 2,000 code completions per month and 50 chat requests per month, running on smaller models. Cursor, Devin Desktop, ChatGPT, Claude and Gemini also offer free access with usage limits — check their official pricing pages for the current allowances.

In practice, the free tier is enough when AI is an occasional helper: a question here, a snippet there, a block of unfamiliar code to explain. Two patterns push you toward a paid plan. The first is when completions become part of your daily typing rhythm — 2,000 a month sounds generous until suggestions start firing on every line you write. The second is when you lean on agents for multi-step work, since a single agent run works through many steps and consumes a free allowance far faster than one question does.

Which tool should you choose?

No single tool fits every situation. If you want a coding assistant built into a familiar workflow, GitHub Copilot is a sensible choice. If you are ready to move to an AI-centered environment, Cursor and Devin Desktop offer whole-project capabilities. For analysis, refactoring and reviewing complex code, Claude stands out for its reasoning. Meanwhile, ChatGPT and Gemini suit lookups, learning and conversational problem solving. In practice, many development teams combine several tools to take advantage of each solution’s particular strengths.

Frequently asked questions

Is Windsurf still available?

Yes. Windsurf was not discontinued — it was renamed. Cognition acquired the product on 14 July 2025 and rebranded it as Devin Desktop on 2 June 2026, and windsurf.com now redirects to devin.ai/desktop. The JetBrains plugin is the one exception and still uses the “Windsurf for JetBrains” name.

Do AI coding tools replace developers?

These tools are designed to assist rather than replace developers. They speed up writing and reviewing code, but people still make the decisions about architecture, business logic and quality control.

Should I use one tool or several at once?

It depends on your needs and budget. Many developers combine a coding assistant inside the editor with a conversational model for analysis, using each tool’s strengths for different kinds of tasks.

How much do these tools cost?

Each tool has its own pricing model, usually including a limited free tier and paid monthly plans. Among the AI-first editors, Cursor Pro and Devin Desktop Pro both cost 20 USD per month; Devin Desktop is up from the 15 USD charged when the product was called Windsurf.

Are AI coding tools safe for proprietary or sensitive code?

It depends on each tool’s data handling and settings. Review the provider’s privacy terms, enterprise options and any code-retention policies before using them on confidential projects, and follow your organization’s own security guidelines.

Do I need prior experience to use AI coding tools?

Not strictly, though a background helps. Beginners can use them to learn and generate examples, while experienced developers use them to speed up routine work. In every case, understanding the output remains important for quality and safety.

Can these tools understand an entire large project?

Whole-project understanding varies. AI-first editors like Cursor and Devin Desktop (formerly Windsurf) are designed to work across a codebase, while editor assistants focus more on local context. Results still improve with clear structure and well-described requests.

Features, pricing and free-tier limits change frequently; verify against each product’s official page before making a decision.
