10 Best AI Coding Assistants of 2026

By the KeenVerdict research desk · Updated November 9, 2026 · Next review December 24, 2026 · 10 products scored

Our pickGitHub CopilotDevelopers and teams who want AI in the editor they already use and on github.com, at a low per-seat price.9.2

Our verdict

Pick GitHub Copilot if you want one assistant that works in almost every editor and on github.com, at the lowest per-seat price for a full feature set. Choose Claude Code if you prefer to describe a task and review the result, since it runs the same agent in the terminal, IDE, Slack and web. Codex is the natural choice if you already pay for ChatGPT, and Cursor fits developers who want an AI-first editor with cloud agents. Antigravity and Devin Desktop are worth a look for agent-heavy work, Kiro for credit-based team budgets, JetBrains AI for IntelliJ users, Zed for a fast open-source editor and Amp for agents that run in cloud machines. Most have a free tier, so test two on a real repository before you buy seats.

The short answer

GitHub Copilot is the best AI coding assistant for most developers and engineering teams in 2026, with a free plan and Pro at $10 per month; Claude Code suits developers who hand whole tasks to an agent in the terminal, from $17 per month billed annually; Cursor Plus and ChatGPT Go, which includes Codex, are the cheapest paid plans at $8 per month.

This list is for developers and engineering teams adding AI code completion, chat and agents to an editor or terminal. It covers editor add-ons such as GitHub Copilot and JetBrains AI, AI-first editors such as Cursor, Devin Desktop, Kiro, Zed and Google Antigravity, and terminal or cloud agents such as Claude Code, OpenAI Codex and Amp. We compared documented features and published prices from each vendor's own pages; we did not run hands-on tests. Scores weigh features at 40 percent, ease of use at 30 and value at 30. Tabnine was left out because its website now redirects to Tricentis, and Gemini Code Assist because Google stopped selling new Standard and Enterprise subscriptions on October 9, 2026 and points users to Antigravity. Amazon Q Developer, still sold at $19 per user per month, and Replit, which is built for creating whole apps from prompts, narrowly missed the cut.

    GitHub Copilot

    GitHub's AI pair programmer with completions, chat, agent mode, code review and a cloud agent that opens pull requests.

    Price

    Free plan; Pro $10, Pro+ $39 and Max $100 per user per month

    Quoted from the GitHub Copilot pricing page on November 9, 2026: $ 10 USD per user / month

    GitHub Copilot earns the top spot because it gives the most developers the most for the least money. The Free plan includes 2,000 completions a month, agent mode, the Copilot CLI and MCP support, which is enough to judge it on real work. Pro at $10 per user per month removes the completion cap and adds the cloud agent, which takes an issue and opens a pull request, plus code review on GitHub and in the editor. Pro+ at $39 adds premium models such as Opus and can hand tasks to third-party agents from Anthropic and OpenAI. Editor coverage is the widest we found: VS Code, Visual Studio, Xcode, JetBrains IDEs, Neovim, Eclipse and Zed. The catch is metering. Agent mode, code review, the cloud agent and the CLI all spend GitHub AI Credits, and Pro includes $15 of them a month, so teams running agents all day will want Pro+ or Max.

    What works

    • +Pro at $10 per user per month is the lowest full-featured price here
    • +Works in more editors than any rival, from Xcode to Neovim
    • +Pro+ can delegate tasks to the Claude and Codex agents

    What does not

    • −Free plan caps completions at 2,000 per month
    • −Premium models such as Opus need Pro+ at $39 per month
    • −Agent work draws from monthly AI credits that heavy users can exhaust

    Claude Code

    Anthropic's coding agent that reads a codebase, edits files and runs commands from the terminal, IDE, Slack, web or phone.

    Price

    Included in Claude Pro at $17 per month billed annually or $20 monthly; Max from $100 per month; Team $20 per seat per month billed annually

    Quoted from the Claude Code pricing page on November 9, 2026: $17 Per month with annual subscription discount

    Claude Code is the strongest agent-first option we compared. Instead of suggesting the next line, it takes a task such as a bug fix, a test suite or a multi-day migration, reads the relevant files, edits code and runs commands while you steer and review. Anthropic lists the same agent in the terminal, VS Code, JetBrains, Slack, the web, iOS, Android and GitHub, plus a desktop app for macOS, Linux and Windows, so you can start a task at a desk and check it from a phone. It comes with Claude Pro at $17 per month billed annually or $20 monthly, which also covers the Claude chat app. Max at $100 per month gives five times Pro usage. For companies, Team costs $20 per seat billed annually for 2 to 150 people and includes up to $500 a month in pooled API credits. The trade-offs are limits that reset every five hours and every week, and no free tier for Claude Code itself.

    What works

    • +Strong fit for multi-file tasks you can describe and then review
    • +One subscription covers Claude chat and Claude Code
    • +Team plan is $20 per seat billed annually for 2 to 150 people

    What does not

    • −Not included on the free Claude plan
    • −Usage limits reset every 5 hours and every week
    • −No classic inline autocomplete, since it works as an agent

    OpenAI Codex

    OpenAI's coding agent on the web, in the CLI, in an IDE extension and on iOS, included with ChatGPT plans.

    Price

    Free plan; Go $8 per month; Plus $20 per month; Pro at $100, $200 or $500 per month

    Quoted from the OpenAI Codex pricing page on November 9, 2026: Use Codex for lightweight coding tasks. $8 /month

    Codex makes the most sense for the many developers who already have a ChatGPT subscription. OpenAI sells it inside ChatGPT plans: Free and Go at $8 per month run GPT-6 Luna at standard speed in the desktop app, subject to rollout, while Plus at $20 per month opens Codex on the web, in the CLI, in the IDE extension and on iOS, with GPT-6.1 Sol, automatic code review and a Slack integration. Pro comes in $100, $200 and $500 monthly sizes, and the top size adds an ultrafast mode. Teams can also run Codex with an API key for CI jobs, though that path drops the cloud features such as GitHub review. The main limit is that Codex shares its usage pool with ChatGPT Work, so heavy chat users and heavy coders on one account compete for the same allowance. For a developer who wants agent help and chat on one bill, it is good value.

    What works

    • +Comes with ChatGPT, so many developers already have access
    • +Go at $8 per month is one of the cheapest paid entries
    • +Pro is sold in three sizes, so heavy users can scale up

    What does not

    • −Free and Go are limited to GPT-6 Luna in the desktop app
    • −Cloud features such as GitHub code review need Plus or higher
    • −Codex shares usage limits with ChatGPT Work

    Cursor

    An AI-first code editor from Anysphere with agents, cloud agents, a CLI, Slack integration and AI code review.

    Free plan; Plus $8 per month with Grok models only; Premium $30 per month; Teams from $30 per user per month

    Quoted from the Cursor pricing page on November 9, 2026: Plus $8 /month

    Cursor remains one of the most capable AI editors, with agents that can run on their own cloud machines to build, test and demo features, plus a CLI, a Slack bot and Bugbot reviews on pull requests. Its pricing has changed shape, though. Plans are now sold through X Subscription Corp and share one AI usage pool across Cursor and Grok, and the page lists X perks such as a premium checkmark next to the coding features. Plus at $8 per month is cheap but limited to Grok models. Premium at $30 adds four times the usage, cloud agents, automations and code review, and opens third-party models such as Claude and GPT, billed at API list price on top of the plan. Super and Ultra raise usage to 15 and 50 times Plus. Teams start at $30 per user with SSO and privacy controls. Strong product, but the real monthly cost depends on which models you use.

    What works

    • +Editor and agents are designed together
    • +Usage allowance refreshes weekly
    • +Teams plan adds SAML and OIDC SSO and usage analytics

    What does not

    • −Plus at $8 includes Grok models only
    • −Third-party models are billed separately at API list price
    • −Plans now bundle X and Grok features that many developers will not use

    Quoted from the Devin Desktop pricing page on November 9, 2026: $20 per month Select plan

    Devin Desktop is the new name for Windsurf, and Cognition says plans, pricing, extensions and settings carried over in a standard update. The editor keeps unlimited Tab completions and inline edits on every plan, Free included, which makes the free tier useful for daily typing help. Pro at $20 per month raises agent quotas, opens frontier models from OpenAI, Claude, Gemini and SpaceXAI, adds free use of the in-house SWE-2 model and connects to Devin Cloud, so a session can move from a laptop to the cloud and keep running. Agents from other vendors plug in through the Agent Client Protocol. Usage refreshes daily and weekly, and extra usage is sold at API pricing. Teams costs $80 per month plus $40 per full developer seat, for up to 200 users, with an admin dashboard and analytics. The gap between Pro and the $200 Max tier is the main weakness for power users.

    What works

    • +Free plan keeps completions and inline edits unlimited
    • +Usage refreshes daily and weekly, with extra usage at API pricing
    • +Existing Windsurf plans and prices carried over unchanged

    What does not

    • −Teams pricing adds an $80 monthly base fee
    • −Max jumps from $20 to $200 per month with no middle tier
    • −The rename from Windsurf may confuse procurement and docs searches

    Price

    Free individual plan; higher limits with Google AI Pro at $19.99 per month; business plans via Google Cloud from $30 per seat

    Quoted from the Google Antigravity pricing page on November 9, 2026: $19.99 / month Get 4x higher usage access than Free

    Antigravity is now Google's main coding product. Google stopped serving Gemini Code Assist for individual users on June 18, 2026, and stopped selling new Standard and Enterprise subscriptions on October 9, pointing everyone to Antigravity. The platform has four parts: a desktop app for managing several local agents in parallel, a terminal CLI with background subagents, a full IDE with an agent manager, and extensions for VS Code and JetBrains. An SDK lets teams build custom agents on the same harness. The free individual plan includes a range of agent models, unlimited Tab completions and command requests, with basic weekly rate limits. Google AI Pro at $19.99 per month raises those limits and adds an AI credit pool, along with the wider Gemini subscription. Organizations buy through Google Cloud, where Gemini Enterprise Standard and Plus start at $30 per seat. Value is high, but the plan structure is spread across several Google pages.

    What works

    • +Free plan includes unlimited Tab completions and command requests
    • +Google AI Pro also covers the Gemini app and other Google AI features
    • +Runs on macOS, Windows and Linux

    What does not

    Free plan with 50 credits; Pro $20, Pro+ $40, Pro Max $100 and Power $200 per user per month

    Quoted from the Kiro pricing page on November 9, 2026: KIRO PRO $20 per user / month 1,000 credits

    Kiro stands out for how plainly it prices agent work. Every tier lists its credits: 50 on Free, 1,000 on Pro at $20 per user per month, 2,000 on Pro+ at $40, 5,000 on Pro Max at $100 and 10,000 on Power at $200, with add-ons at $0.04 per credit. Teams of two or more can buy $20 seats that each add 500 credits to a shared pool, and admins set limits for people and groups. The product itself is agent-first. You set intent and context, and Kiro agents plan, build, review and verify work locally or in the cloud, then wait for approval before merging. Kiro Crew adds persistent agents that watch a backlog, codebase or CI and act when work appears. Auto mode routes prompts across models, or you can pick GPT-5.6, Claude Opus 5 or open weight models. The free tier is narrow, and credit multipliers make per-task costs harder to predict.

    What works

    • +Clear credit counts on every tier, from 50 to 10,000 a month
    • +Add-on credits cost $0.04 each
    • +First upgrade includes the rest of the month free and 500 trial credits

    What does not

    • −Free tier is limited to open weight models and Claude Sonnet 4.5
    • −Credit multipliers vary by model, so costs per task differ
    • −GovCloud pricing is about 20 percent higher

    US price check pending. See the JetBrains AI pricing page.

    JetBrains AI is the natural choice for teams that live in IntelliJ IDEA, PyCharm, WebStorm or the other JetBrains IDEs. Every plan, including AI Free, gives unlimited AI completion inside the IDE, and the free tier adds 3 monthly AI credits. AI Pro raises that to 10 credits and adds coding agents: JetBrains' own Junie plus Claude Agent, Codex and Gemini. AI Ultimate includes 35 monthly credits for frequent agent use, and credits can be topped up at API rates. A big plus is openness. Through the Agent Client Protocol you can connect more than 25 outside agents, including Cursor and GitHub Copilot, or bring API keys from Anthropic, OpenAI and Google. JetBrains Air tracks parallel agent sessions and opens diffs with the IDE's own tools. The limits are small credit allowances on the lower tiers and a free tier restricted to commercial IDE versions. Prices showed in euros from our location, so the USD check is pending.

    What works

    • +Free tier includes unlimited completion in commercial IDEs
    • +Agent diffs open directly in the IDE for review
    • +Works with AI subscriptions you already pay for

    What does not

    • −AI Free is only available for commercial IDE versions

    Free Personal plan; Pro $10 per month with $5 of tokens; Business $30 per seat per month

    Quoted from the Zed pricing page on November 9, 2026: $10 per month The next-generation code editor + AI.

    Zed is the pick for developers who care about editor speed and want control over which AI they use. The Personal plan is free forever and allows unlimited use with your own API keys or outside agents such as Claude Agent, Codex and OpenCode through the Agent Client Protocol. Pro at $10 per month adds Zed-hosted models, unlimited edit predictions and $5 of tokens, with usage beyond that billed at API list price plus 10 percent. A 14-day Pro trial with $5 of usage needs no credit card. The agent works inside the editor, finds context, edits files and shows its changes in an editable unified diff that you accept or reject. Business at $30 per seat adds org-wide model policies, data sharing controls and unified billing, but SSO, SAML and SCIM are listed as planned rather than available. It has fewer built-in agent features than the leaders, and hosted usage costs can climb.

    Free Hobby plan with pay-as-you-go orbs; Individual from $20 per month; Teams at no extra charge

    Quoted from the Amp pricing page on November 9, 2026: Individual $20 ∕ mo.

    Amp is built for developers who want agents to run in the cloud rather than on their laptop. Each thread can get an orb, a cloud machine with your code, tools and plugins set up, so you can send a prompt, close the laptop and check progress later from the macOS, iPhone, iPad or Android apps or the terminal. It routes work across several models, including GPT-5.6 and Claude Fable 5.1. Pricing is unusual. The Hobby plan has no monthly fee: you bring a ChatGPT or Claude subscription or your own keys with no Amp token fees, and pay as you go for Amp-hosted orbs. The Individual tier starts at $20 per month and includes 45,000 minutes of orb time plus Amp credits. Team workspaces cost nothing extra and add shared threads and pooled credits. Amp's stated habit of removing features with no backward compatibility suits early adopters more than conservative teams.

    What works

    • +No Amp token fees when you use your own subscription or key
    • +Self-hosted orbs are free on Hobby, Individual and Teams
    • +Team workspaces cost nothing extra

    What does not

Before you choose

Decide between completion and agents

Inline completion suggests the next lines as you type and is unlimited on paid plans at Copilot, Devin Desktop, Antigravity, JetBrains and Zed. Agents read the codebase, edit many files and run commands. They use far more model capacity, so agent usage is what plan limits and credits are really measuring.

Read how usage is counted

Every vendor here meters agent work differently. Copilot uses monthly AI credits, Kiro sells 1,000 credits on Pro, Claude and Codex share limits with their chat apps, Devin Desktop refreshes quotas daily and weekly, and Zed bills tokens at API list price plus 10 percent after $5. Estimate a heavy week, not an average day.

Check which models you get

Cursor Plus at $8 per month includes Grok models only, and third-party models on higher Cursor plans are billed at API list price. Copilot, Devin Desktop and Kiro let you pick from several labs. If your team has a preferred model, confirm it is in the plan you are buying.

Keep your editor if you can

Switching editors costs time. Copilot supports VS Code, Visual Studio, Xcode, JetBrains IDEs, Neovim, Eclipse and Zed, and Claude Code has VS Code and JetBrains extensions. JetBrains, Zed and Devin Desktop also connect outside agents through the Agent Client Protocol.

Plan team controls early

Team features vary widely. Claude Code Team covers 2 to 150 seats, Devin Desktop Teams covers up to 200 users, Kiro pools credits across seats, and Zed lists SSO, SAML and SCIM as planned but not yet available. Ask for SSO, audit logs and data retention terms before a company rollout.

Questions readers ask

What is the best AI coding assistant in 2026?
GitHub Copilot is our top pick for most developers and teams, with a free plan, Pro at $10 per user per month and support for VS Code, Visual Studio, Xcode, JetBrains IDEs and more. Claude Code ranks second for agent-based work, from $17 per month billed annually.
Which AI coding assistant is free?
GitHub Copilot, OpenAI Codex, Cursor, Devin Desktop, Google Antigravity, Kiro, JetBrains AI, Zed and Amp all have a free tier. Devin Desktop and Antigravity include unlimited Tab completions for free, and Copilot Free includes 2,000 completions a month.
What is the cheapest paid AI coding assistant?
Cursor Plus and ChatGPT Go, which includes Codex, both cost $8 per month, but Cursor Plus is limited to Grok models. GitHub Copilot Pro and Zed Pro cost $10 per month.
Is Claude Code or GitHub Copilot better?
Copilot is better if you want inline completion in many editors and agents tied to GitHub issues, from $10 per month. Claude Code is better if you mostly delegate multi-file tasks to an agent from the terminal or IDE, and it comes with Claude Pro at $17 per month billed annually.
What happened to Windsurf and Gemini Code Assist?
Windsurf has been renamed Devin Desktop, and Cognition says existing plans and prices stay the same. Google stopped selling new Gemini Code Assist Standard and Enterprise subscriptions on October 9, 2026 and directs users to Google Antigravity.
