10 Best AI Code Assistants in 2026
Short answer: GitHub Copilot Pro at $10 a month when the team already lives in GitHub and VS Code. Cursor Pro at $20 a month when you will switch editors for the agent. Claude Pro at $17 a month, billed annually, when the work is a terminal agent and chat can share one pool.
The sticker is the wrong number to compare, because chat, agents, and completions are metered differently. Dupple data: Toolradar, our software directory, tracks 153 AI coding tools as of September 2026. This page is the assistant you leave open while you edit, and app builders and sandboxes are in best AI for coding. Prices below were checked on each vendor's site on September 23, 2026, and the wider catalog is Toolradar's guide.
Quick comparison
| Tool | Best for | Starting price | Standout |
|---|---|---|---|
| GitHub Copilot | A GitHub org that will not change editors | $10/mo Pro | Paid plans do not bill completions |
| Cursor | An editor you will actually switch to | $20/mo Pro | Daily agent use sits on Pro+ |
| Claude Code | Multi-file work from the terminal | $17/mo annual Pro | Included on paid Claude plans |
| Devin Desktop | Tab completions plus an IDE agent | Same monthly price as Cursor Pro | Windsurf's old plan link opens Devin |
| Gemini Code Assist | A Google Cloud seat with admin controls | $22.80/user monthly | Individual IDE access ended June 18, 2026 |
| Amazon Q Developer | An AWS account, including Java upgrades | $19/user Pro | The fee starts on first use, not on login |
| JetBrains AI | Staying inside IntelliJ-family IDEs | 10 credits / 30 days on AI Pro | A credit is $1, and Free is 3 per 30 days |
| Augment Code | One flat fee for up to 50 seats | $20/mo Standard | Included usage also pays a 40% model fee |
| Tabnine | Air-gapped or private-model deployments | 39/user/mo annual | Your own model is unlimited usage |
| Cline | A VS Code agent with your own API key | No seat fee | Enterprise is a quote |
What an AI code assistant is
An AI code assistant completes, chats about, or edits code inside an IDE or a terminal, billed as a seat or a usage pool, while a person still merges the diff.
Copilot, Cursor, Devin Desktop, Gemini, Q, JetBrains, Augment, and Tabnine are that seat. Claude Code and Cline do the same job from the terminal or an extension. A pull-request bot is a different buy, in AI code review tools, and a prompt that builds an app is vibe coding.
How we chose
Toolradar's AI coding category lists 153 tools, updated September 2026, and I ranked 10 assistants you can keep open while editing. Plan names and prices come from each vendor's site on September 23, 2026. I did not run a shared benchmark, no vendor paid for a slot, and the directory's own order is a different list.
Continue is off this ranking because its site says it has joined Cursor.
GitHub Copilot, the default seat on GitHub
GitHub Copilot is the buy when the company is already on GitHub and people will stay in VS Code, Visual Studio, or JetBrains. The plans page still does not cover GitHub Enterprise Server.
Who it's for: Teams that want completions in the current editor, with a credit pool for chat, the CLI, and the cloud agent.
Free includes 2,000 completions a month and auto model selection only. Pro is the table row: 1,000 base credits plus a 500-credit flex allotment, 1,500 total. Pro+ is $39 a month with 7,000 credits, and Max is $100 a month with 20,000. Business is $19 per granted seat with 1,900 credits, and Enterprise is $39 per granted seat with 3,900, pooled across the enterprise.
The catch: On the individual billing page, one credit equals $0.01, and chat, the CLI, and agents spend credits while completions stay unlimited on paid plans. Unused credits expire monthly, a granted Business seat bills if the IDE stays closed, and usage past an org pool uses that same rate.
The first seat on GitHub, and a poor fit for Enterprise Server or a day spent in the cloud agent.
Cursor, when the editor is the product
Cursor is a separate editor, so switching is the decision. Daily-agent math is on the models doc, plan names are on the pricing page, and the terminal alternative is Claude Code vs Cursor.
Who it's for: People who will leave VS Code and can accept a bill that moves with the model.
Hobby is free, with limited Agent requests and Tab completions. Pro is the table's entry price, while Pro+ is $60 a month, Ultra is $200 a month, Teams Standard is $40 a user, and Teams Premium is $120 a user for 5x Standard agent limits. Paid individual plans include unlimited Tab and two pools: Cursor models (Grok 4.7, Grok 4.6, Grok 4.5, Composer 2.5) and other models at API price.
The catch: Daily agent users typically land between the Pro+ price and $100 a month, and heavier automation often runs past Ultra. Teams and Enterprise add $0.25 per million tokens on third-party models, including Auto routes, while Grok and Composer are exempt, and a Teams admin can force privacy mode.
Buy it if the editor switch is acceptable, and budget Pro+ when the agent runs every day.
Claude Code, included with paid Claude
Claude Code edits a repo from the terminal, the desktop app, and supported editors. The pricing page includes it on every paid plan and leaves it off Free.
Who it's for: Developers who want a terminal agent on the Anthropic bill they already expect to pay.
Pro is the annual price in the table, $200 up front, or $3 more month to month. Max starts at $100 a month, at 5x or 20x Pro usage per five-hour session. Team standard seats are $25 a month, or $5 less annually, for 2 to 150 people, and Premium seats are $125 a month, with a lower annual rate on that page. Enterprise is a per-seat annual fee plus API usage, and the seat matches Cursor's Pro price.
The catch: The terminal shares usage with chat on the web, desktop, and mobile, so a heavy coding day can lock the chatbot. Limits reset on a five-hour window, paid plans add weekly caps, and there is no fixed message count. Context goes up to 1 million tokens and varies by model, and SSO and SCIM are not on Pro or Max, so those controls mean Team or Enterprise.
The right terminal agent on one Anthropic bill, and the wrong one if that pool must stay reserved for chat.
Devin Desktop, the Windsurf pricing page now
Devin Desktop is the editor on Cognition's plan list: Tab, inline edits, agent quotas, and Devin Cloud on paid plans. Windsurf's pricing address now opens that list, and the older name still has a Toolradar entry.
Who it's for: Someone who wants uncapped Tab on a free install, then a paid quota for repo edits.
Free is a light agent quota, limited models, unlimited inline edits, and unlimited Tab. New Pro matches Cursor's Pro price, with frontier models, Devin Cloud, and extra usage at API rates. SWE-2 Free is included in the desktop app and CLI through October 10, 2026. Max is $200 a month, and Teams is $80 a month plus $40 per full developer seat, with unlimited flex seats, and SSO is Enterprise.
The catch: The quota doc grandfathers existing Pro at $15 a month, so old and new invoices differ, and quotas refresh daily and weekly. Devin Cloud is an autonomous agent beside the editor, closer to AI agents than to a completion seat.
A fair editor when free Tab is the trial, and a messy contract if the paperwork still says Windsurf.
Gemini Code Assist, after the free plugin ended
Gemini Code Assist covers VS Code, JetBrains, Cloud Workstations, and Cloud Shell, with agent mode in preview on the business page.
Who it's for: A company that wants a licensed seat and Google Cloud controls, not a personal Google account in the IDE.
Standard is the monthly figure in the table, and annual is $19 a user, paid up front. Enterprise is $54 a month, or $45 on an annual commitment. The deprecation note says that on June 18, 2026 the IDE extensions and Gemini CLI stopped serving individuals, Google AI Pro, and Google AI Ultra, while Standard and Enterprise were not cut off.
The catch: The old individual plugin is not a supported plan. Private codebase customization has no separate price line, so confirm the tier before assuming Standard includes it.
The Google Cloud seat, and a closed door on the old free plugin.
Amazon Q Developer, billed on first use
Amazon Q Developer is the IDE and CLI assistant on the pricing page. Pro also runs in the Kiro IDE, covered in best AI for coding.
Who it's for: AWS teams, especially those planning Java upgrades, who want IP indemnity and an admin dashboard.
Free is 50 agentic requests a month and 1,000 lines for Java upgrades. Pro is the table seat: a higher agentic limit, 4,000 Java lines a month per user pooled at the payer account, Identity Center, and IP indemnity. Past that pool, lines are $0.003, and the FAQ describes Pro as about 10,000 inference calls a month, roughly 1,000 user requests, and says extra agentic use waits until next month.
The catch: Login does not start the fee, because a completion, an agent request, or a transform does, and the first month is pro-rated while a mid-month cancel still costs the full month. Free IDE limits apply to Builder ID users, and Pro is automatically opted out of data collection. One quota page counts agentic requests as lines of code, which disagrees with the FAQ.
The AWS default, with a trigger that bills the first completion and a transform meter separate from chat.
JetBrains AI, a small credit pack
JetBrains AI sits inside JetBrains IDEs, and the license doc prices individuals and organizations apart, and a credit equals $1.
Who it's for: People who will not leave IntelliJ, PyCharm, WebStorm, GoLand, or Rider, and who use the agent only sometimes.
Free is 3 credits per 30 days, then Individual AI Pro is $10 for 10 credits per 30 days, and AI Ultimate is $30 for 35. Organization AI Pro costs twice the individual price, with 20 credits. Organization AI Ultimate is $60 for 70 credits, and Enterprise matches that Ultimate price, and the credit count is unpublished. Top-ups last 12 months, and the docs estimate about 10 chat code-generation requests per credit.
The catch: Individual Pro runs out once agent mode is the habit. AI Free is missing from Android Studio and from the Community editions of PyCharm and IntelliJ IDEA. The IDE license and the AI license are separate, except where a pack such as DataSpell already includes AI Pro.
A sensible add-on to an IDE you already pay for, and too small if the agent writes most of the code.
Augment Code, a flat fee and a thin pool
Augment Code charges the team, not the seat, and the pricing page caps Standard and Business at 50 people and meters one shared balance.
Who it's for: Under 50 people who want one invoice and no charge for idle seats.
Standard is the flat fee in the table, with the same number of dollars of included usage. Business is $100 a month with a matching balance. Enterprise is custom, and that card lists SSO, OIDC, and SCIM, while outside top-ups last 12 months. Paid plans say they do not train on your data.
The catch: The balance pays model list price, a 40% fee on LLM usage, and compute. Heavy and light users share it, and Person 51 is Enterprise, and dedicated support is Enterprise too.
A real alternative to per-seat bills for a small team, until you mistake the included dollars for raw model spend.
Tabnine, private deployment after Tricentis
Tabnine says on its pricing page that Tricentis has acquired it. You can run SaaS, VPC, on-premises, or a full air gap.
Who it's for: A review that will not accept the vendor's cloud model and can bring its own LLM.
Code Assistant is 39 per user per month, billed annually. The Agentic Platform, with the context engine, CLI, and MCP, is 59 per user per month on the same annual term. The page does not label the currency, and your own on-prem or cloud model is unlimited usage, and Tabnine-supplied models add a 5% handling fee on the provider price.
The catch: There is no monthly checkout, so a pilot is still an annual quote. Air-gap and zero retention are the point, and they leave model operations with you, and IP indemnification depends on the terms.
The privacy seat when the model stays in your network, and a slow buy if you wanted to pay by card today.
Cline, no seat fee if you bring the model
Cline is an open-source VS Code agent, plus a CLI, that spends your inference. The pricing page splits that install from an Enterprise quote.
Who it's for: Developers holding their own API keys, or a platform team that will not buy tokens from the assistant vendor.
The extension has no seat fee, and you pay the provider or Cline's usage rates. Enterprise is custom and adds JetBrains, SSO, SCIM, audit logs, VPC, centralized billing, and an SLA.
The catch: Free is the extension, not the model, and one long frontier-model session can pass a Copilot Pro afternoon, and only your own key cap stops it, while admin controls are the Enterprise quote.
The bring-your-own-key agent, and a finance problem once the API bill is open.
Pricing: what a team actually pays
Ten Copilot Business seats are $190 a month before extra credits, because the meter is granted seats. Augment Standard stays a flat fee up to its headcount cap, then the 40% model fee spends the included balance. Cursor daily agent use is the Pro+ band, and Teams Premium is the $120 seat plus the third-party token rate.
Claude's annual Pro is paid up front, and the terminal shares that plan with chat. Do not mix a new Devin Pro price with a grandfathered account. Q's per-line charge hits Java transforms past the pool, not chat. JetBrains top-ups are how a 10-credit Pro survives an agent, and Tabnine's 5% fee applies only when Tabnine supplies the model.
How to choose
Stay on Copilot when version control is GitHub and the complaint is typing speed. Move to Cursor for multi-file edits if people will change editors. Use Claude Code when the terminal can share the Anthropic pool, and read Codex vs Claude Code before a second terminal agent.
Use Devin Desktop for a free Tab trial, Gemini or Q when that cloud is already standard, and JetBrains AI when the IDE is. Use Augment for a small team on one invoice, Tabnine when the model cannot leave the network, and Cline when an API invoice is clearer than a seat. For a coding chat, start with Claude vs ChatGPT for coding and how to use AI for coding, and the wider stack is the developer AI stack.
Common mistakes
Treating Copilot Pro as an unlimited agent fails, because completions are the unlimited part while chat and the cloud agent spend the 1,500 credits, and Business bills every granted seat.
Stopping at Cursor's entry price leaves the daily-agent bill on the Pro+ band, and Teams third-party models also pay the per-million token rate.
Buying Claude Code as a second subscription pays twice, because it is already on paid Claude plans and the terminal and the chatbot share one pool.
Quoting new Devin Pro to a grandfathered account will not match the invoice, because existing Pro stays at the $15 rate and SSO is not on the $80 base plan.
Sending someone to the free Gemini plugin points at a closed plan, because individual access has ended and Standard is the current entry.
Assuming Q starts when you assign a user misses the trigger, because the fee starts on a completion, an agent run, or a transform, and a mid-month cancel still costs the month.
Reading Augment's flat fee as unlimited use ignores the meter, because the balance also pays the 40% LLM fee, while Tabnine's 39 and 59 rates are annual and Cline moves the cost to the model key.
FAQ
What is the best AI code assistant in 2026?
GitHub Copilot, for a team already on GitHub that will keep its editors, where Pro is the $10 plan, paid plans do not bill completions, and Business is a granted seat with a shared pool. Choose Cursor if you will switch editors and budget the daily-agent tier, and choose Claude Code if a paid Claude plan should cover the terminal. The directory count is not 153 copies of this seat.
How much do AI code assistants cost in 2026?
In September 2026 the table holds Copilot Pro, Cursor Pro, Claude's annual Pro, and Gemini's monthly Standard rate. Devin Desktop Pro matches Cursor's monthly price, Q Pro is the $19 seat, and JetBrains individual AI Ultimate is the $30 pack. Cline has no seat fee, and Tabnine lists 39 and 59 per user per month on an annual subscription.
Is there a free AI code assistant in 2026?
Copilot Free includes 2,000 completions a month, and Cursor Hobby limits Agent and Tab, and Devin's free plan has unlimited Tab, with a light agent quota. JetBrains AI Free is 3 credits per 30 days, Cline has no seat fee and you still pay inference, and Gemini's individual IDE access has ended. Q's free tier is 50 agentic requests a month.
Should I use GitHub Copilot or Cursor?
Use Copilot when GitHub is the host, Enterprise Server is not, and completions are the win. Use Cursor when you will change editors for cross-file agent edits, and its models doc puts daily agent users on the Pro+ band, above the Pro toggle, and the longer write-up is Claude Code vs Cursor.
Is Claude Code a separate product I have to buy?
No, it is included on Pro, Max, Team, and Enterprise, and absent from Free. Annual Pro is the $17 rate, paid as the up-front charge in the Claude section, and usage is shared with chat. A second terminal agent is a separate invoice, compared in Codex vs Claude Code.
What happened to Windsurf and the free Gemini plugin?
Windsurf's pricing address now opens Devin's plans, and the editor there is Devin Desktop. New Pro matches Cursor's Pro price, and grandfathered Pro stays at $15 a month. Gemini's individual IDE access and Gemini CLI consumer access stopped on June 18, 2026, while Standard and Enterprise licenses stayed.
Do I still need a review tool?
Yes, when the risk is a bad merge rather than slow typing. An AI code review tool comments on the pull request, and static analysis enforces a rule the model does not know.
Bottom line
Start with Copilot when GitHub is the host, move to Cursor when the agent is worth an editor change, and use Claude Code when you already pay Anthropic and can share that pool. Match Devin, Gemini, Q, or JetBrains to the editor or cloud you already have. Use Augment, Tabnine, or Cline when the bill should not be a normal per-developer sticker.
