10 Best AI Coding Assistants of 2026

This list is for developers choosing a coding assistant on price, usage limits and free plans. We compared documented features and published prices on each vendor's own pages and scored value at 40%, features at 35% and ease of use at 25%. Starting prices are the cheapest paid plan in USD per month. JetBrains showed only euro prices from our location, so its price is marked pending. Gemini Code Assist and Amazon Q Developer are not listed separately: Google moved consumer users to Antigravity, and AWS points Q Developer IDE users to Kiro.

   Best forDevelopers who want the cheapest full-featured paid plan and support in almost every editor.

   GitHub Copilot ranks first because its $10 Pro plan buys more than any rival at that price. Pro unlocks unlimited code completions and next edit suggestions, pull request reviews, Copilot in the cloud for assigning issues that come back as pull requests, model selection, and access to Claude Code and Codex as third-party agents. GitHub states usage as AI credits: Pro includes $15 of credits a month, built from a $10 base plus a $5 flex allotment that GitHub says may change. Pro+ costs $39 with $70 of credits and premium models including Opus, and Max costs $100 with $200 of credits. The free plan is a real starting point with 2,000 completions a month, Copilot CLI and limited agent mode, and no credit card. Copilot works in VS Code, Visual Studio, Xcode, JetBrains IDEs, Neovim, Eclipse, Zed and on GitHub itself. The weak spot is the shared credit pool: heavy agent or review use spends the same budget, so power users may need extra credits or a higher tier.

   • ✓Pro at $10 a month includes $15 of monthly AI credits
   • ✓Widest editor support on this list
   • ✓Pro can use Claude Code and Codex as third-party agents

   • ✕Free plan caps completions at 2,000 a month
   • ✕Agent mode, code review and the CLI all draw from one credit pool
   • ✕Delegating tasks to Claude and Codex in the cloud needs Pro+ at $39

   Free plan:

   $0, 2,000 completions per month, limited chat and agent usage

   Pro:

   $10 per user per month, $15 monthly AI credits

   Pro+:

   $39 per user per month, $70 monthly AI credits

   Max:

   $100 per user per month, $200 monthly AI credits

   Students:

   Verified students get the Copilot Student plan

   Bottom line: Copilot is the default pick for most developers: the free plan is usable and Pro at $10 is the cheapest full agent plan here. Step up to Pro+ only if you want premium models or cloud delegation to Claude and Codex.

   8.8

   Best forChatGPT users who want a coding agent bundled with their existing plan, starting at $8 a month.

   Codex is bundled into every ChatGPT plan, which makes it easy to try. Free and Go ($8 a month) run GPT-6 Luna at standard speed in the desktop app, which suits small scripts and quick fixes. Plus at $20 is the plan most developers will want: it adds Codex on the web, in the CLI, the IDE extension and on iOS, cloud code review, the Slack integration and the GPT-6.1 Sol model. OpenAI is more open about limits than most vendors. It estimates 15 to 160 local GPT-6.1 Sol messages and 350 to 3,000 GPT-6 Luna messages per five hours on Plus, while noting weekly limits may also apply and cloud tasks cost more. Pro plans at $100, $200 or $500 currently have no five-hour limit. For CI there is an API key mode billed at API prices, without cloud features. The catch is that usage is shared with ChatGPT work, so heavy chat use eats into coding time.

   • ✓Free and $8 Go plans for light use
   • ✓OpenAI publishes estimated message ranges per five hours
   • ✓Usage is shared with ChatGPT, so one subscription covers both

   • ✕Free and Go are limited to GPT-6 Luna in the desktop app
   • ✕Cloud features such as GitHub code review start on Plus at $20
   • ✕Weekly limits may apply on top of the five-hour window

   Free plan:

   $0, GPT-6 Luna in the desktop app

   Go:

   $8 per month

   Plus:

   $20 per month, 15 to 160 local GPT-6.1 Sol messages per five hours

   Pro:

   $100, $200 or $500 per month

   Business:

   $20 per user per month billed annually, $25 monthly

   Bottom line: Codex is the best value if you already pay for ChatGPT, and Go at $8 is one of the two cheapest paid plans here. Choose Plus at $20 for the CLI, IDE extension and code review.

   8.6

   Best forDevelopers who hand off long, multi-file tasks and want Anthropic's Opus and Sonnet models.

   Claude Code is the strongest option on features: it gets Anthropic's Opus, Sonnet and Haiku models, with context windows of up to 1M tokens depending on the model. It drops to third on value because there is no free route in: Claude Free does not include Claude Code, so the entry point is Pro at $17 a month billed annually ($200 up front) or $20 monthly. Limits reset every five hours and every week, and Anthropic says how fast you hit them depends on the model, chat length and file size rather than giving message counts. Max at $100 gives 5x Pro usage plus $100 a month in API credits. Ultra at $200 gives 10x Pro weekly usage, $200 in API credits and no five-hour limit for verified accounts. Teams of 2 to 150 can buy standard seats at $20 a month billed annually, or premium seats with 5x the usage at $100. Usage is shared with Claude chat, so one subscription covers both.

   • ✓Strong model lineup for complex coding work
   • ✓Pro at $17 a month on annual billing
   • ✓Ultra removes the five-hour limit for verified accounts

   • ✕The free Claude plan does not include Claude Code
   • ✕Anthropic does not publish fixed message counts
   • ✕Usage is shared with Claude chat and other Claude features

   Free plan:

   Claude Free exists but does not include Claude Code

   Pro:

   $17 per month billed annually, $20 monthly

   Max:

   $100 per month, 5x Pro usage

   Ultra:

   $200 per month, 10x Pro weekly usage, no five-hour limit

   Team standard seat:

   $20 per seat per month billed annually, $25 monthly

   Bottom line: Claude Code is the pick for developers who give an agent large tasks and want top Anthropic models. Budget at least $17 a month, as there is no free tier for it.

   Best forDevelopers who want a free editor that runs Claude Agent or Codex CLI on their own subscription.

   Zed is an editor first, and its pricing reflects that. The Personal plan is free forever and allows unlimited use with your own API keys or external agents such as Claude Agent and Codex CLI, so developers who already pay for Claude or ChatGPT can get an agent-driven editor for nothing extra. Pro at $10 a month, with a free trial, adds Zed-hosted models, unlimited edit predictions and $5 of tokens, with usage-based billing beyond that. Business at $30 per seat a month adds org-wide AI model policies, data governance controls, role-based access and unified spend visibility, and is self-serve with no seat minimum. Zed is clear that Business seats do not include a fixed credit allotment: teams pay standard rates or bring their own keys. The trade-off is that the $5 token allowance on Pro is small, so heavy hosted-model users will see usage charges. Zed also covers fewer cloud agent features than Copilot or Codex.

   • ✓Personal plan is free forever, including AI with your own keys
   • ✓Pro costs $10 a month
   • ✓Clear usage-based billing beyond the included $5

   • ✕Pro includes only $5 of tokens before usage billing
   • ✕Business seats include no fixed AI credit allotment
   • ✕No free trial on Business

   Personal:

   $0 forever, unlimited use with your API keys or external agents

   Pro:

   $10 per month, unlimited edit predictions, $5 of tokens

   Business:

   $30 per seat per month

   Order forms:

   Available at 25 or more seats

   Bottom line: Zed is the best free option if you already have an AI subscription or API key. Pro at $10 suits developers who mainly want edit predictions.

   Best forDevelopers who want an agent-first editor and are happy to use Grok models or pay API rates for others.

   Cursor's plans have changed shape. Usage is now a pool shared across Cursor and Grok, and the $8 Plus plan, which Cursor calls its introductory plan, covers Grok models only. Premium at $30 a month is the plan Cursor recommends for new AI users: 4x the Plus usage, the latest Grok models, cloud agents and automations, code hosting, AI code reviews through Bugbot, and access to third-party models at API list price. That last point matters: models from other providers are not included in any plan allowance and are billed by usage, though you can set spending caps. Super ($100, 15x Plus) and Ultra ($200, 50x Plus) add priority access. The allowance refreshes weekly, which smooths out heavy days. Teams from $30 per user adds SSO, privacy settings and centralized billing. The editor remains one of the most capable agent environments, but if you want Claude or GPT models, the real cost is the plan plus API usage.

   • ✓Plus at $8 a month is one of the cheapest paid plans here
   • ✓Weekly refresh means one heavy day does not use up the month
   • ✓Teams plan adds SSO, privacy controls and usage analytics

   • ✕Plus includes Grok models only
   • ✕Third-party models are billed separately at API list price
   • ✕Cloud agents, Bugbot and third-party models need Premium at $30

   Free plan:

   $0, limited agent and chat requests

   Plus:

   $8 per month, Grok models only

   Premium:

   $30 per month, 4x Plus usage

   Super and Ultra:

   $100 per month (15x Plus) and $200 per month (50x Plus)

   Teams:

   From $30 per user per month

   Bottom line: Cursor is a capable agent editor with an $8 entry plan, but that plan is Grok only. Developers who rely on Claude or GPT models will pay API rates on top.

   Best forDevelopers who want a free agent IDE with Gemini models, or who already pay for Google AI Pro.

   Antigravity is now Google's route for individual developers: Google says Gemini Code Assist IDE extensions stopped serving consumer tiers on June 18, 2026, and points users to the Antigravity family. That family covers a desktop app, an IDE, a CLI, editor extensions and an SDK. The free plan needs no subscription and includes a variety of agent models, unlimited tab completions, unlimited command requests and basic weekly rate limits. Paid access comes through Google AI plans: Google AI Pro at $19.99 a month adds entry rate limits to the agent model and a flexible AI credit pool, and also bundles Gemini 4 Argon in the Gemini app and 5 TB of storage. Google AI Ultra starts at $99.99 with 5x higher limits, and a $199.99 tier offers 20x. Organizations can buy via Google Cloud, with Gemini Enterprise plans from $30 per seat. The weakness is vague limits: Google describes tiers as entry, higher and highest rather than giving request counts.

   • ✓Free plan includes a variety of agent models
   • ✓Google AI Pro bundles Gemini 4 Argon and 5 TB of storage
   • ✓Replaces Gemini Code Assist for consumer accounts

   • ✕Free tier has basic weekly rate limits
   • ✕Google AI Pro gives only entry rate limits to the agent model
   • ✕Limits are described as tiers rather than fixed counts

   Free plan:

   $0, unlimited tab completions and command requests, basic weekly rate limits

   Google AI Pro:

   $19.99 per month, entry rate limits to the Antigravity agent model

   Google AI Ultra:

   From $99.99 per month, 5x or 20x higher Antigravity limits

   Gemini Enterprise:

   Standard and Plus plans from $30 per seat per month

   Gemini Code Assist:

   Consumer tiers stopped serving requests on June 18, 2026

   Bottom line: Antigravity is a strong free agent IDE and good value if you already pay for Google AI Pro. Developers who need predictable limits should compare Kiro or Codex first.

   Best forDevelopers who want one desktop app to manage several agents and models, plus cloud agents on Pro.

   windsurf.com now serves Devin Desktop from Cognition, positioned as a command center for running agents locally or in the cloud. Through the Agent Client Protocol it can manage other agents and models in one place. The free plan keeps unlimited tab completions and inline edits, with a light agent quota and limited models. Pro at $20 a month adds frontier models from OpenAI, Anthropic, Google and SpaceXAI, leading open source models, free use of Cognition's SWE-2 model and Devin Cloud agents. Max at $200 offers significantly higher quotas. Allowances refresh daily and weekly, and Cognition says most users will not hit them; beyond that you buy extra usage at API pricing. Teams costs $80 a month for the plan plus $40 per full developer seat, for up to 200 users, with centralized billing, analytics and priority support. The downside is opacity: quotas are described as light, increased or significantly higher rather than as numbers.

   • ✓Free plan keeps unlimited tab completions
   • ✓Allowance refreshes daily and weekly
   • ✓Pro includes cloud agents

   • ✕Free plan has only a light agent quota and limited models
   • ✕Extra usage beyond the allowance is billed at API pricing
   • ✕Teams costs $80 a month before per-seat fees

   Free plan:

   $0, light agent quota, unlimited inline edits and tab completions

   Pro:

   Max:

   $200 per month, significantly higher quotas

   Teams:

   $80 per month plus $40 per full dev seat, up to 200 users

   Concurrent sessions:

   Up to 10 on Free and Pro

   Bottom line: Devin Desktop suits developers who juggle several agents and want cloud agents at $20. Kiro or Codex give clearer limits at a similar price.

   Best forDevelopers who want predictable, published credit limits and AWS's replacement for Amazon Q Developer in the IDE.

   Kiro has the clearest limits on this list. Every plan states a monthly credit count: 50 on Free, 1,000 on Pro at $20, 2,000 on Pro+ at $40, 5,000 on Pro Max at $100 and 10,000 on Power at $200, with add-on credits at $0.04 each. A simple prompt can cost under one credit, while spec tasks usually cost more, and Kiro says picking Sonnet 4.6 directly costs 1.3x what Auto would. The free tier includes open weight models and Claude Sonnet 4.5. The first upgrade to Pro gives the rest of the month free plus 500 trial credits valid for 12 months. Paid tiers can choose GPT-5.6, Claude Opus 5, Sonnet 5 and open weight models such as DeepSeek 3.2. Kiro also matters for AWS users: AWS says it will end support for Amazon Q Developer IDE plugins on April 30, 2027 and points developers to Kiro. Teams can pool credits at $20 per seat with 500 credits each.

   • ✓Plain credit counts on every plan
   • ✓First upgrade gets the rest of the month free plus 500 trial credits
   • ✓Free tier includes Claude Sonnet 4.5

   • ✕Free plan has only 50 credits a month
   • ✕Complex spec tasks can use several credits each
   • ✕Choosing a specific model can cost more credits than Auto

   Free plan:

   $0, 50 credits per month

   Pro:

   $20 per user per month, 1,000 credits

   Pro+:

   $40 per user per month, 2,000 credits

   Pro Max and Power:

   $100 (5,000 credits) and $200 (10,000 credits)

   Add-on credits:

   $0.04 per credit

   Bottom line: Kiro is the pick for developers who want to know exactly what $20 buys. It is also where Amazon Q Developer users should look next.

   Best forDevelopers who already pay for ChatGPT or Claude and want hosted agent environments without token markups.

   Amp prices differently from everyone else here: it does not sell model usage. You bring tokens from anywhere, including ChatGPT and Claude subscriptions or your own API keys, and Amp charges no token fees or limits. What you pay for is orbs, hosted environments where agents keep running after you close your laptop. The free Hobby plan covers all product features, unlimited self-hosted orbs or your own runners, and pay-as-you-go Amp-hosted orbs. The $20 Megawatt plan includes 45,000 minutes of orb time, unlimited repositories and custom domains for portals. Teams cost nothing extra on top of members' tiers and add thread sharing, multiplayer, shared plugins and skills, SAML SSO and pooled credits. Enterprise adds SCIM, audit logs and IP allowlisting. This model is good value for developers who already pay for a frontier model, but total cost is Amp plus your model provider, and newcomers must learn how orbs work.

   • ✓Free Hobby plan with your own model access
   • ✓No Amp markup on model tokens
   • ✓Teams cost no extra charge per member

   • ✕Model usage is paid separately to your provider
   • ✕The $20 plan buys orb minutes, not model usage
   • ✕Orb concept takes some learning

   Hobby:

   Free, pay as you go for Amp-hosted orbs

   Megawatt:

   $20 per month, 45,000 minutes of orb time

   Teams:

   No extra charge, members choose their own tier

   Model access:

   Bring your own subscriptions or API keys

   Bottom line: Amp is the pick for developers who want hosted, long-running agents on the model subscription they already have. If you do not have one, a bundled plan such as Copilot or Codex is simpler.

    Best forDevelopers who work in IntelliJ IDEA, PyCharm or other JetBrains IDEs and want agents without leaving them.

    JetBrains AI makes most sense if your day already runs in a JetBrains IDE. The AI Free tier gives unlimited AI completion and 3 monthly AI credits, but only for commercial IDE versions. AI Pro adds 10 monthly credits and access to Junie, Claude Agent, Codex and Gemini, with a 30-day free trial. AI Ultimate gives 35 monthly credits, 5 of them bonus credits, for frequent agent use. Top-up credits are priced at API rates and stay valid for 12 months. JetBrains also lets you sign in with existing provider accounts to run 25+ agents through the Agent Client Protocol, including Cursor, Codex and GitHub Copilot, or bring your own API keys from Anthropic, OpenAI and Google. That flexibility is the strength. The weakness is the small credit allowance on Pro for agent work, and from our location the pricing page showed euros only, so the USD price check is pending and value is scored conservatively.

    • ✓Free tier includes unlimited completion
    • ✓Use existing Copilot, Cursor or Codex subscriptions via ACP
    • ✓30-day free trial of AI Pro

    • ✕Free tier only works with commercial IDE versions
    • ✕AI Pro includes just 10 AI credits a month
    • ✕USD prices were not shown from our location

    AI Free:

    Unlimited completion, 3 monthly AI credits

    AI Pro:

    10 monthly AI credits, 30-day free trial

    35 monthly AI credits including 5 bonus

    Agents:

    Junie, Claude Agent, Codex, Gemini

    Price check:

    Pending: page showed EUR only

    Bottom line: JetBrains AI is the natural choice inside IntelliJ or PyCharm, especially if you bring another agent subscription. Expect to top up credits for regular agent use.
