AI coding tools split into two genuinely different products that get reviewed as if they were one. The first finishes the line you are typing. The second takes a description of a task, edits a dozen files, runs your test suite, reads what broke and tries again. Almost all the progress since 2024 has been in the second kind, and almost all the disappointment comes from expecting the first kind to behave like it.
The agents are now good enough that the interesting question is no longer whether they work but what they cost, and the answers differ wildly. A flat $20 hides the model bill inside a subscription. Cline shows it to you and caps nothing. Claude Code is the most capable of the lot and the only one you cannot try without paying, because Anthropic’s free plan excludes it outright.
One constant across all of them: point these tools at a repository under version control and read the diff before you merge. That single habit is what separates teams who find agents transformative from teams who find them dangerous.
Once you have picked a tool, the practical workflows are how to use Claude Code, Claude Code pricing, how to use Cursor AI, how to use GitHub Copilot, how to use Devin Desktop (ex-Windsurf), Devin AI review, Cline AI guide, and how to use Replit Agent. Assistant-first (autocomplete vs agents): best AI coding assistants. New to agents entirely? Start with how to build your first AI agent. If connectors beyond the repo are on the table, read What is MCP? before granting tool access.
If you have already narrowed it to two, we have written the head-to-heads: Claude Code vs Cursor, GitHub Copilot vs Claude Code, Cursor vs GitHub Copilot, Cursor vs Windsurf — the last of which also explains what the Windsurf rename did and did not change — and OpenAI Codex vs Claude Code for the ChatGPT-bundled agent against Anthropic’s. For prompt-to-app prototypes rather than IDE agents, see Lovable AI app builder and Replit vs Lovable.
The ranking
The most capable agentic tool here: it edits across the codebase, runs your tests, reads the failures and tries again. Ranked first on capability despite being the only one with no free tier at all.
The best balance of agent and editor. If you want one tool that is excellent at both completing your line and completing your task, and you would rather not think about model billing, this is the safe choice.
The most conservative pick and still the best value inside an existing GitHub workflow. Less ambitious than the agents above, which for a lot of teams is the point.
The best value if you already hold API keys: the extension is free and open source, and you pay model providers directly with no markup. The trade is that nothing caps your spend.
The one to use when the constraint is that you have no development environment. Everything runs in the browser, which makes it the most practical option for learners and quick prototypes.
Renamed Devin Desktop in June 2026 and repositioned around orchestrating agents — including other vendors' agents, via the open Agent Client Protocol, which nothing else here does. The most generous free tier of the six. The churn is real: three product names in three years, and two overlapping local agents shipping side by side.
Side by side
| Tool | Rating | Pricing | Best for |
|---|---|---|---|
| Claude Code | 5/5 | From $20/mo with Claude Pro · or API pay-per-token | Working developers who want an assistant that finishes a task — writes the tests, runs them, fixes what fails — rather than suggesting the next line. |
| Cursor | 5/5 | Free · Pro $20/mo | Developers who want AI woven into their editor, not bolted on. |
| GitHub Copilot | 5/5 | Free tier · from $10/mo | Developers who want AI autocomplete and help inside their editor. |
| Cline | 4/5 | Free and open source · you pay your own model costs | Developers who want an agentic assistant without a subscription, and who would rather see the model bill itself than have it hidden inside a monthly fee. |
| Replit | 4/5 | Free · from $20/mo | Building and shipping working apps from plain English, no setup. |
| Devin Desktop | 4/5 | Free tier · Pro $20/mo · Max $200/mo | Developers who want a full IDE that treats coding agents as the main event, and who are comfortable being on a product mid-transition. |

Head to head
- Claude Code vs CursorCursor if you want one tool that is both your editor and your agent, with a predictable bill. Claude Code if the agent is the point and you are happy to keep your own editor — it goes further on hard, multi-file work, and it is the only one of the two you cannot try for free.
- Cline vs Claude CodeCline if you already hold API keys and want to see exactly what every task costs, with no subscription and no vendor lock — accepting that nothing caps the spend. Claude Code if you want the most polished agent on a predictable monthly bill, and can accept that there is no free tier at all and that heavy days eat the same budget as your Claude chats.
- Cursor vs GitHub CopilotGitHub Copilot if you want strong AI assistance without changing anything about how you work, at half the price. Cursor if you want an agent that takes on whole tasks and you are willing to switch editors to get it.
- Cursor vs Devin DesktopCursor if you want the most polished single-vendor experience and a cheaper team price at $40 a seat. Devin Desktop — the product formerly called Windsurf — if you want one editor that can run other companies' agents, including Codex and Claude Agent, through the open Agent Client Protocol. Your Windsurf plan and settings carried over untouched in the rename.
- GitHub Copilot vs Claude CodeGitHub Copilot if you want predictable cost and unlimited in-editor completions for $10 a month. Claude Code if you want an agent that takes on whole tasks across files — accepting $20 a month minimum, no free tier, and a usage budget you share with your Claude chats.
- Replit vs CursorReplit if you want to describe an app and have it built, hosted and deployed without setting anything up on your machine. Cursor if you already have a development environment and want to write code faster inside it. They both cost $20, but Replit's $20 is a credit wallet you can spend in a week, while Cursor's is an allowance you would have to work hard to exhaust.
How to choose
- Decide whether you want an agent or an assistant
- These tools split into two jobs. Autocomplete-style assistants finish the line you are typing and never surprise you. Agents take a task, change many files, run commands and hand you a diff. The second kind saves far more time and requires you to review its work like a colleague's pull request.
- Fixed price hides the cost; usage price shows it
- Cursor, Copilot and Claude Code charge a flat fee and absorb the model cost, which is predictable. Cline charges nothing and passes the provider bill straight through, which is transparent and uncapped. Neither is wrong, but pick deliberately — and if you pick usage-based, set a spending limit before your first real task.
- Free tiers vary more than anywhere else in our catalogue
- Cline is free and open source. Devin Desktop, Cursor, Copilot and Replit all have usable free tiers. Claude Code has none whatsoever — the free Claude plan explicitly excludes it. That makes it the only tool here you cannot evaluate without paying.
- Team pricing is not the individual price times seats
- Checked 2 August 2026: Cursor is $40 per user per month for Teams, double its $20 individual rate. Devin Desktop charges an $80 monthly team fee plus $40 per full dev seat, so a five-developer team pays roughly $280 against Cursor's $200 — and the base fee hurts smallest teams most. GitHub Copilot Business is $19 per seat, the cheapest of the three, and includes having your code excluded from training. Work this out before you standardise, because it is the number that scales.
- An agent needs a repository it can safely break
- Anything on this list that edits files should be pointed at a project under version control, with a clean git status when you start. This is not a formality: the difference between an agent being an asset and a liability is almost entirely whether you can review and revert what it did.
Coding FAQ
- What is the best AI coding tool in 2026?
- Claude Code, if you want an agent that finishes whole tasks and you can afford $20 a month minimum. Cursor if you want one tool that is strong at both autocomplete and agentic work with predictable billing. GitHub Copilot if you want the least disruptive option inside an existing workflow.
- Is there a free AI coding assistant?
- Cline is free and open source, though you pay your own model costs. Devin Desktop, Cursor, GitHub Copilot and Replit all have free tiers with limits. Claude Code is the exception — there is no free access to it at all.
- What happened to Windsurf?
- Cognition renamed it Devin Desktop on 2 June 2026 and pushed the change as an automatic update. Plans, pricing, extensions and settings all carried over — the vendor's FAQ says only the name and branding changed, and windsurf.com now redirects to devin.ai/desktop. We previously said Cascade had been discontinued; that was wrong and we corrected it on 2 August 2026 after checking the official docs, where Cascade still has a full section. What actually changed is emphasis: the product now leads with managing coding agents rather than being an AI-assisted IDE. Full detail in our [Cursor vs Windsurf comparison](/compare/cursor-vs-windsurf/).
- Will these tools write code I can actually ship?
- For well-scoped, conventional work — tests, refactors, boilerplate, bug fixes with a clear reproduction — routinely yes. For novel architecture or anything subtle, they produce a confident draft that needs a real review. The teams getting value from these tools are the ones reviewing every diff.
- How much should I budget per month?
- Around $20 covers Cursor, Copilot or Claude Code at the entry tier. Heavy agentic use pushes Claude Code towards $100 or more, and Cline's bring-your-own-key model commonly lands between $20 and $70 depending entirely on which model you point it at.
