Best AI Coding Assistants Compared (2026): Copilot, Cursor, Windsurf, Tabnine & Amazon Q Developer

Five well-known AI coding tools compared on the things that decide a purchase: whether the AI lives in your current editor or replaces it, free tiers, what the paid plans really include, privacy and deployment options — and, new in 2026, whether you can still sign up at all.

Last updated: November 2026 · Prices in USD, checked against vendor pricing information in November 2026 · How we compare: this guide is based on publicly available vendor specifications and pricing. We do not claim hands-on testing we haven't done, we publish no benchmark scores, and there are no paid placements.

Affiliate Disclosure: Some links on this page may become affiliate links in the future. If you sign up through an affiliate link, we may earn a commission from the vendor at no extra cost to you. At the time of writing, the outbound links on this page are placeholders and none of the vendors below runs a public affiliate program we could verify — see our plan notes. Either way, commissions never change which products we include or the facts we publish: every price, limit and availability note below is taken from the vendors' own public pages.
Availability check first (November 2026): Two of the five tools in this comparison cannot be bought by new users right now. Tabnine was acquired by Tricentis in July 2026 and no longer offers self-serve sign-up or a public pricing page. Amazon Q Developer closed to new sign-ups in May 2026, and AWS plans to end support for its IDE plugins on April 30, 2027, pointing users to its newer Kiro product instead. Both are included below for existing users weighing their options — not as things you can newly buy. GitHub Copilot, Cursor and Windsurf (now Devin Desktop) are on sale and accepting new users.

The five tools in detail

GitHub Copilot — AI help inside the editor you already useOn sale

Copilot is not an editor: it is an extension that adds completions, chat, agent mode and code review to VS Code, JetBrains IDEs, Visual Studio, Neovim, Xcode and others, with deep ties to GitHub itself. The plan ladder is the widest here: a free tier with limited completions and chat, Pro ($10/mo) for individuals, Pro+ ($39/mo) and Max ($100/mo) with larger allowances, and Business ($19/user/mo) / Enterprise ($39/user/mo) for organizations. Since June 2026 the paid plans include a monthly allowance of "AI Credits" (Pro includes 1,500), and heavier agent or premium-model use consumes more — so the subscription price is a floor, not a guaranteed total.

STRENGTHS (per published specs)

  • Works inside the widest range of existing editors — no migration needed
  • Lowest paid entry price ($10/mo) among the tools on sale, plus a usable free tier
  • Team controls, policy management and IP indemnity on Business and up

TRADE-OFFS

  • Usage-based AI Credits make heavy agent users' monthly cost less predictable than the sticker suggests
  • The experience depends on your host editor — it does not redesign the editor around AI the way Cursor or Devin Desktop do
  • Model choice and limits differ by plan, so the plan page needs a careful read
See Copilot plans

Cursor — the editor built around AI agentsOn sale

Cursor is a standalone editor based on VS Code, designed around chat, an agent that edits multiple files, inline edits and codebase-aware answers. Its pricing changed substantially in 2026: in October 2026 Cursor moved new customers to plans sold as part of "The X Subscription" — Free, Plus ($8/mo), Premium ($30/mo), Super ($100/mo) and Ultra ($200/mo) — while existing customers were told their previous plans (Hobby free, Pro $20/mo, Pro+ $60/mo, Ultra $200/mo) continue. One detail matters more than the tier names: the included usage pool now covers Cursor's own models (Grok and Composer), and third-party models such as Claude, GPT and Gemini are billed separately at API list price on Premium and above. Budget for both parts.

STRENGTHS (per published specs)

  • Editor, agent and chat designed as one product rather than an add-on
  • Free plan, and a low $8/mo entry tier if its own models are enough for you
  • Cloud agents, automations and code-review features on Premium and up

TRADE-OFFS

  • Requires switching editors (familiar if you come from VS Code, still a switch)
  • Total cost is genuinely two-part: subscription plus API-priced third-party model usage
  • Plan names and structure changed in 2026 — older reviews describe plans that are no longer sold to new users
See Cursor plans

Windsurf, now Devin Desktop — agent-led editor with a generous free tierOn sale

This tool has had three names: it began as the Codeium completion plugin, became the Windsurf editor in 2024, and was renamed Devin Desktop in June 2026 after Cognition (the company behind the Devin agent) acquired it. windsurf.com now redirects to Devin's site, and Cognition says existing plans, settings and extensions carry over. The editor keeps its VS Code-based layout and pairs a local agent with cloud agents managed from a command center. Current pricing on Devin's site: Free with unlimited Tab completions and a light agent quota, Pro ($20/mo) with full model availability and higher quotas, Max ($200/mo) for heavy use, and Teams ($80/mo base plus $40 per developer seat). Allowances refresh daily and weekly rather than monthly.

STRENGTHS (per published specs)

  • Unlimited Tab completions on the free plan — the most generous completion tier here
  • Local and cloud agents in one product, if you run longer tasks
  • Pro at $20/mo includes access to OpenAI, Anthropic and Google frontier models per the vendor's pricing page

TRADE-OFFS

  • Two rebrands in two years — documentation, invoices and old tutorials use different product names
  • Quota system (daily/weekly refresh) is harder to compare directly with monthly credit pools
  • Requires switching editors, like Cursor
See Devin Desktop plans

Tabnine — the privacy-first option, now enterprise sales onlyNo new self-serve sign-up

Tabnine was one of the earliest AI code assistants (launched in 2018) and built its reputation on privacy: completions and chat inside major IDEs, a public commitment to zero code retention, and deployment choices no other tool here matches — SaaS, VPC, on-premises, or fully air-gapped. That made it the default candidate for regulated industries. The situation changed in 2026: the earlier free and low-cost individual plans were discontinued, the last published pricing was Code Assistant ($39/user/mo, annual) and Agentic Platform ($59/user/mo, annual), and after Tricentis acquired Tabnine on July 30, 2026, its site moved under Tricentis with no public pricing page and no self-serve checkout — new business is handled through sales, and existing customers continue to be supported. If you are an enterprise evaluating private deployment, it remains a legitimate conversation to have with their sales team; if you are an individual developer, there is currently nothing to sign up for.

STRENGTHS (per published specs)

  • Widest deployment range here, including on-premises and air-gapped
  • Zero code retention positioning and compliance certifications aimed at enterprises
  • Bring-your-own-model option made usage unlimited on the last published terms

TRADE-OFFS

  • No self-serve sign-up and no public pricing as of November 2026 — individuals and small teams are effectively excluded
  • Highest entry price of the five at its last published rates, on annual terms
  • Integration into the acquirer's platform makes the long-term product shape uncertain

Amazon Q Developer — for existing AWS customers onlyClosed to new sign-ups

Amazon Q Developer was AWS's assistant across the IDE, the command line and the AWS Console, with distinctive features such as Java application transformation (upgrades) and AWS account and diagnostics help. Its pricing was simple — a free tier with 50 agentic requests a month and Pro ($19/user/mo) with higher limits, admin controls and IP indemnity. However, AWS closed Q Developer to new sign-ups on May 15, 2026, and has announced that support for the IDE plugins ends on April 30, 2027, directing users to Kiro, its newer agentic IDE. Existing subscribers can keep using and even add seats for now, but anyone choosing a tool today should treat Q Developer as a migration source, not a destination.

STRENGTHS (per published specs)

  • Deep AWS integration — console help, diagnostics and Java upgrade tooling in one assistant
  • Simple two-tier pricing while it was on sale
  • Free tier was perpetual rather than a timed trial

TRADE-OFFS

  • Closed to new sign-ups since May 2026 — you cannot start with it today
  • IDE plugin support ends April 30, 2027, so existing users need a migration plan
  • Its strengths are AWS-specific; it was never the general-purpose pick

How to choose in four steps

STEP 1

Decide: plugin or new editor?

If you want to keep your current setup, the choice is a plugin — Copilot is the one you can still buy. If you're willing to switch editors for an agent-first workflow, compare Cursor and Devin Desktop.

STEP 2

Check you can actually buy it

In 2026 this is a real step, not a formality: Tabnine is sales-only after its acquisition, and Amazon Q Developer is closed to new users entirely. Confirm sign-up status on the vendor's site before investing evaluation time.

STEP 3

Price the whole month, not the sticker

All three buyable tools meter usage somehow: Copilot's AI Credits, Cursor's separate API-priced third-party models, Devin Desktop's quotas. Estimate your agent-heavy days, not just your completion days.

STEP 4

Run the free tier on your own code

Copilot, Cursor and Devin Desktop all have free tiers. Spend a few days with each on a real project — including one messy, multi-file change — and keep the one whose suggestions and agent behavior fit how you actually work.

FAQ

I'm learning to code. Which one should I start with?

Start with a free tier and don't pay yet. GitHub Copilot's free tier works inside editors you may already use for courses (VS Code, for example), and Copilot has historically offered free access for verified students — check GitHub's current student terms. Devin Desktop's free plan is generous if you mainly want completions while you learn. Paid agent features matter more once you're building larger projects of your own.

What is the difference between a plugin tool and an AI editor?

A plugin (Copilot, Tabnine, Amazon Q Developer) adds AI features to an editor you already have. An AI editor (Cursor, Devin Desktop) is a separate application — both are based on VS Code — where chat, agents and multi-file editing are built into the core experience. Plugins minimize disruption; dedicated editors go further in redesigning the workflow around AI.

Why do the monthly prices not tell the whole story?

Because all three tools you can buy now meter AI usage on top of the subscription: Copilot includes a monthly AI Credits allowance, Cursor bills third-party models (Claude, GPT, Gemini) at API list price outside its included pool, and Devin Desktop uses refreshing quotas with extra usage at API pricing. Light completion use fits comfortably in the base plans; daily agent use is what pushes the total up.

What happened to Windsurf and Codeium?

Same product, new owners and names. Codeium launched the Windsurf editor in 2024; Cognition acquired Windsurf in 2025 and renamed the editor Devin Desktop on June 2, 2026. windsurf.com redirects to devin.ai, and the vendor states that existing plans and settings carry over.

Can I still sign up for Tabnine or Amazon Q Developer?

Not as a new self-serve customer, as of November 2026. Tabnine (acquired by Tricentis in July 2026) is sold through its sales team with no public pricing page. Amazon Q Developer closed new sign-ups in May 2026 and its IDE plugins are scheduled to end on April 30, 2027; AWS directs users to Kiro. Existing customers of both are still supported for now.

Which tool is best if my code can't leave our network?

That requirement is exactly what Tabnine built its business on, with VPC, on-premises and air-gapped deployment options — but it is now an enterprise, sales-led purchase. If you are an individual or small team with strict privacy needs, evaluate the paid tiers' privacy modes and data policies of the buyable tools carefully, and confirm current terms with the vendor before committing.

Why are there no speed benchmarks or "best overall" scores here?

Because this guide is compiled from the vendors' published specifications, pricing and availability notices, not from paid placements or invented lab testing. AI coding tools also change models and plans frequently — several changed during the writing of this page — so we show the verifiable facts (form factor, limits, metering, sign-up status) and let you test the free tiers on your own code.
