What is the best AI coding assistant in November 2026?

What an AI coding assistant is now

An AI coding assistant is a per-seat subscription that puts a model inside your editor, terminal or repository and meters how much of it you may use each month. The five products that matter for most buyers in late 2026 are GitHub Copilot, Cursor, Claude Code, OpenAI Codex and the Windsurf editor now sold under Devin.

All five converged on the same commercial shape: a free tier, a $10 to $30 entry tier, a $100 to $200 ceiling for heavy agent use, and a per-seat business plan. What separates them is not the model list, which now overlaps almost completely, but three things a pricing page will tell you if you read it closely: how much metered usage the entry tier includes, whether the advertised monthly price requires an annual commitment, and whether the allowance is stated in units you can compare with a competitor.

That last point is where most buying decisions go wrong. Two vendors can both charge $20 and mean completely different things by it.

Best AI coding assistant prices, verified 1 November 2026

The table below was read off each vendor's own pricing page on 1 November 2026. Figures are per seat, in US dollars, monthly billing unless the cell says otherwise, and exclude tax. Where a vendor publishes usage in multiples rather than absolute units, the multiple is reproduced as published rather than converted.

Two structural notes before the numbers. Cursor's entry plan is now Plus at $8, not the $20 Pro tier that most comparison posts still quote. And the Windsurf brand has folded into Devin: windsurf.com/pricing returns a 308 redirect to devin.ai/pricing, which carries the editor plans alongside Devin cloud agents.

Copilot: a flat $10 per 1,000 credits, at every tier

GitHub is the only vendor here that publishes an absolute allowance, and its documentation makes the internal economics visible. Copilot Pro is $10 per month for 1,000 base GitHub AI Credits. Pro+ is $39 for 3,900. Max is $100 for 10,000. Copilot Business is $19 per granted seat for 1,900 credits per user, and Enterprise is $39 per seat for 3,900.

Divide each price by its credits and every tier lands on exactly $10.00 per 1,000 credits. Upgrading is not a volume discount, then. It is prepaying credits at a fixed unit price, with the higher tiers bundling model access on top: Pro gets a selection of models, Pro+ and Max get access to premium models, and Max adds priority access. Copilot CLI and the Copilot app are included on all plans, including Free.

That flat curve makes the decision simple. If you do not exhaust 1,000 credits in a month, Pro is the right buy and Pro+ is a $29 monthly donation. If you blow through 1,000 in the first week of agent work, Max at $100 is cheaper than two Pro+ seats and saves you the second invoice.

Cursor: an $8 entry, but usage is quoted only in multiples

Cursor's own page lists five individual tiers: Free at $0, Plus at $8, Premium at $30, Super at $100 and Ultra at $200, plus Teams at $30+ per user per month. Usage is expressed relative to Plus: Premium gets 4x, Super 15x, Ultra 50x.

Convert those multiples back into money and the curve is steeper than Copilot's. At Plus you pay $8.00 per Plus-equivalent unit of usage. At Premium it falls to $7.50, at Super $6.67, and only at Ultra does it drop to $4.00. So Premium buys 4x the usage for 3.75x the price, a real but modest step, while Ultra halves the unit cost of a Plus unit. If you are trying to decide between Super and Ultra, that is the number that matters.

There is a catch the multiples hide. Cursor states that third-party models are billed separately at standard model rates and don't draw from your plan's usage pool. A plan can look generous and still produce an extra invoice in the month you point your agent at a frontier model that is not in Cursor's own pool.

And because Cursor never publishes how many credits a Plus unit equals, you cannot honestly compare a $30 Cursor plan with a $39 Copilot plan. Any article that puts them in one column as if the units were the same is guessing.

Claude, Codex and Devin: three $20 plans, three different traps

Claude. Anthropic's page prices Pro at $20 per month, or $17 per month if you pay $200 up front for a year. That annual figure saves $40 over twelve monthly payments, so the $17 headline is a year's commitment, not a discount you can try for a month. Max is $100 and the new Ultra tier is $200, which adds a $200 monthly API credit allowance on top of 10x Pro weekly usage. Claude Code is included from Pro upward and is explicitly not part of the Free plan. Team seats are $25 per seat monthly for standard and $125 for premium, or $20 and $100 if billed annually.

Codex. OpenAI sells Codex inside ChatGPT plans: Free, Go at $8, Plus at $20, Pro from $100 with plans at $100, $200 and $500, and Business at $25 per user per month billed monthly or $20 billed annually for two or more users. Plus is the tier that unlocks Codex in the CLI, the IDE extension, the web app and on iOS. The trap is on the same page: ChatGPT Work and Codex share usage. A team that runs ChatGPT Work all day on the same $20 subscription is quietly drawing down the coding allowance.

Devin (formerly Windsurf). Devin Pro is $20 per month with full model availability, free use of the SWE-2 model and access to cloud agents, with extra usage purchasable at API pricing. Max is $200. Team plans are $80 per month for the plan plus $40 per full developer seat, capped at 200 users, and Enterprise is quoted on request. Anyone comparing Windsurf quotes from 2025 is comparing a product that no longer has its own pricing page.

What five seats actually cost

Individual pricing hides the number a business actually signs. Take five developers, all on monthly billing, and multiply out the published team rates. Copilot Business comes to $95 a month at $19 per seat. Claude Team standard is $125 at $25 per seat. ChatGPT Business with Codex is $125 at $25 per user. Cursor Teams lands at $150 or more, since the page quotes $30+ per user. Devin Teams is the outlier at $280: an $80 platform fee plus $40 per full developer seat.

That is a spread of nearly 3x for five people, and the gap is not model quality. Copilot and Cursor sell a seat with a usage allowance attached. Devin sells a seat plus access to autonomous cloud agents, which is a different product with a different cost base. If your team wants a coding assistant and not an agent that runs its own tickets, the $185 monthly difference buys a lot of credits elsewhere.

Annual billing is the other lever. Claude Team standard drops from $25 to $20 per seat, and ChatGPT Business from $25 to $20 per user. On five seats that is $300 a year each, roughly two months free, in exchange for paying up front.

The install channel is now part of the buying decision

On 29 October 2026, Cursor published a security notice confirming that versions 2.1.312 and 2.1.313 of Anthropic.claude-code in the Cursor VS Code Extension Marketplace were malicious. Cursor says the modified build was available from about 2:27am to 1:35pm PT, that it was not developed by Anthropic, and that it has been removed.

What it did, per the notice: collected hostname, username, operating system, architecture, home directory, environment variable names, working directories, configured Git email and public IP, then appended an attacker-controlled key to ~/.ssh/authorized_keys, tried to enable the local SSH service and open a reverse tunnel, and installed persistence through a macOS LaunchAgent or a scheduled task.

Phorion's technical advisory adds two details worth knowing. The payload sat in an injected function at the top of extension.js and ran when Node loaded the file, before the extension's own activate callback, so opening the editor was enough. And on macOS the SSH enablement step fails for a standard user, because systemsetup -getremotelogin returns an administrator-access error rather than "Off"; the key and persistence still land, but the inbound path breaks on a Mac that was not already running SSH.

Cursor's remediation advice matters for buyers: uninstalling the extension may not be enough, because the payload drops standalone persistence scripts. Check for the key with grep -qs svc-telemetry ~/.ssh/authorized_keys on macOS, look at the key fingerprint rather than the comment string, and rotate credentials reachable from the host.

The purchasing lesson is unglamorous. An extension listed in a marketplace as "official" is not a security control. When two assistants are within $10 of each other on price, the one you can install from a vendor-signed channel, into an environment where extension versions are logged and pinned, is the cheaper product.

Which one to buy

• Solo developer, predictable budget: Copilot Pro at $10. It is the only entry tier with a published allowance, so the bill cannot surprise you.
• Agent-heavy work, several parallel tasks: Cursor Premium at $30 or Super at $100. The 4x and 15x steps are real, but budget for third-party model charges on top.
• You want Claude Code plus chat in one subscription: Claude Pro at $20 monthly, or $17 if you are willing to commit $200 for the year.
• You already pay for ChatGPT: Plus at $20, with the caveat that Work and Codex draw from one pool.
• Team of 5 to 20 with SSO: Copilot Business at $19 per seat is the cheapest per head and the only one of the three that publishes a per-seat credit allowance. Claude Team at $25 and ChatGPT Business at $25 are the alternatives if you are tied to those models.

FAQ

Is Cursor cheaper than GitHub Copilot?

Cursor Plus is $8 per month against Copilot Pro at $10, so yes on sticker price. The allowances are not comparable: GitHub publishes 1,000 AI credits for Pro, while Cursor only says Premium includes 4x the usage of Plus. Without an absolute figure from Cursor, the two cannot be lined up honestly.

Does Claude Pro include Claude Code?

Yes. Anthropic's comparison table marks Claude Code as included on Pro, Max and Ultra and not included on Free. Pro is $20 per month, or $17 per month if you pay $200 for a year up front.

Can you still buy Windsurf?

The windsurf.com pricing URL now redirects to devin.ai/pricing, where the editor is sold as Devin: Free, Pro at $20 per month, Max at $200, and Teams at $80 per month plus $40 per full developer seat.
