Visibility in this ranking can be paid for. Payment gives a vendor more visibility, higher up on the review pages; it never adds a vendor, and it never changes a word of the review. The largest vendors in AI coding assistants
cannot hold places 1 to 3. Places 1 to 3 go to challengers, vendors outside the best-known brands in a category,
wherever the category has them; the established names follow from place 4 in their ranked order. How it works: placement disclosure ·

The 12 tools, reviewed
#1 Zed
A fast code editor with agents, built by its own team · United States · zed.dev
Own-key friendly Editor first Low entry price
Zed takes first place because it is the cheapest way to try AI-assisted coding without handing a vendor your workflow. The pricing page lets a developer run the editor free, plug in keys from Anthropic, OpenAI, Mistral, Ollama or others, and pay Zed nothing for that traffic.
- Pricing: Per seat / month. Personal is free with 2,000 accepted edit predictions. Free plan: free plan.
- Best for: Developers who want their own keys
- Strengths: Edit predictions; Agent panel; Bring your own API keys.
Where it falls short
Zed is an editor first, so a team standardized on a JetBrains IDE or Visual Studio gets nothing from it. The $5 monthly token credit is small and usage beyond it is billed separately.
Wrong for
Teams that live inside IntelliJ-family IDEs, or buyers who want one flat seat price covering heavy agent usage.

#2 Cline
Open source coding agent that uses your own model keys · United States · cline.bot
Apache 2.0 Bring your own key VPC and air-gapped
Cline ranks second because it separates the agent from the model bill more cleanly than anything else on this list. The repository carries an Apache 2.0 license, the pricing page says individuals pay only for inference, and the keys come from Anthropic, OpenAI, Google, Bedrock, Vertex or others.
- Pricing: Open source + paid tiers. Free for individual developers, who pay only for model inference by usage; Enterprise is quote only. Free plan: open source.
- Best for: Teams that want open code and own keys
- Strengths: Plan and Act modes; Terminal command execution; MCP server support.
Where it falls short
There is no flat monthly price, so a heavy agent session can produce a surprising API invoice and nobody at Cline caps it for you.
Wrong for
Finance-led buyers who need predictable per-seat spend, and developers who want autocomplete without managing keys.

#3 Augment Code
Coding agents with a codebase context engine · United States · augmentcode.com
Context engine Pooled credits SOC 2 Type II
Augment Code is third: its pricing is the most unusual here and rewards teams that read it carefully. Usage is pooled across a team and billed in dollars as model inference at provider list price, a flat 40% service fee on that inference, and compute time.
- Pricing: Flat monthly + usage. Standard is $20 per month flat with $20 of usage, Business $100 with $100 of usage, both up to 50 seats. Free plan: none.
- Best for: Mid-sized teams with large codebases
- Strengths: Context engine; VS Code and JetBrains; Auggie CLI.
Where it falls short
The 40% fee on top of model cost is a real surcharge that grows with use. Unused monthly credits do not roll over, though top-ups last twelve months.
Wrong for
Solo developers who want a free tier, and teams that can run their own keys more cheaply.

#4 JetBrains AI Assistant
AI chat and agents inside JetBrains IDEs · Czech Republic · jetbrains.com
JetBrains IDEs Credit tiers Czech vendor
JetBrains AI Assistant earns its place because for a Java, Kotlin or Python shop already paying for IntelliJ or PyCharm it adds AI without a second editor. The documentation says it can be activated through a JetBrains subscription, personal API keys, a provider account or external agents, so the model choice is not locked to one maker.
- Pricing: Credits / month. AI Free gives 3 credits per 30 days. Free plan: free plan.
- Best for: Teams already on IntelliJ-family IDEs
- Strengths: Context-aware AI chat; Coding agents; In-editor generation.
Where it falls short
Credits are opaque: one credit buys roughly ten chat generations or forty editor generations, so a month of agent work can drain 20 credits quickly. The free tier of 3 credits per 30 days is a sampler.
Wrong for
Developers who work in VS Code or a terminal, and teams that want unlimited autocomplete for a fixed fee.

#5 Cursor
AI-native editor built around a coding agent · United States · cursor.com
AI-first editor Privacy mode Usage on top
Cursor lands in fifth place under the rule that dominant products cannot take the top three. It is the clearest example of the editor-as-product approach: the docs describe a coding agent that understands a repository, plans changes and works with rules, plugins and MCP servers, and it connects to GitHub, GitLab and Azure DevOps.
- Pricing: Per seat / month + usage. Free has limited agent requests. Free plan: free plan.
- Best for: Individual developers wanting an AI editor
- Strengths: Agent mode; Cloud agents; MCP servers.
Where it falls short
The headline price is a floor.
Wrong for
Organizations that need a fixed annual bill with no metering, or developers who want to keep their current IDE.
Visit Cursor →
#6 Claude Code
Terminal and IDE coding agent from Anthropic · United States · claude.com
Agent first Subscription or API Runs on Bedrock and Vertex
Claude Code takes sixth place. It reads a codebase, edits files, runs commands and opens pull requests, and the docs show it working from a terminal, VS Code, JetBrains, a desktop app and the web. Its configuration is plain files: a CLAUDE.md for standards, hooks that run shell commands around actions, and skills a team can share.
- Pricing: Per seat / month or API usage. Included in Claude Pro at $17 per month billed annually ($20 monthly), Max from $100, Team from $20 per seat. Free plan: none.
- Best for: Engineers delegating multi-file tasks
- Strengths: Terminal CLI; VS Code and JetBrains extensions; Desktop and web sessions.
Where it falls short
It speaks only to Anthropic models, so a team that wants to compare vendors mid-task cannot.
Wrong for
Developers who want inline autocomplete as they type, and buyers who must keep every vendor swappable.

#7 GitHub Copilot
GitHub's assistant for completion, chat and agents · United States · github.com
GitHub native IP indemnity Free tier
GitHub Copilot is seventh, a major vendor placed by the rule rather than by weakness. For a company whose code, reviews and issues already live on GitHub, the plan page shows how little there is to set up: assign a pull request to the agent, get a review, accept inline suggestions.
- Pricing: Per seat / month + credits. Free includes 2,000 inline suggestions a month. Free plan: free plan.
- Best for: Teams standardized on GitHub
- Strengths: Inline suggestions; Chat and agent mode; Pull request code review.
Where it falls short
Plans now include a dollar amount of AI credits, such as $15 on Pro, so heavy agent users can run out and need a bigger tier. Pro and Pro+ carry no IP indemnity.
Wrong for
Teams on another Git host, and individual freelancers who need legal cover for generated code.

#8 Windsurf (Devin Desktop)
Cognition's agent editor, formerly Windsurf · United States · devin.ai
Cognition product Local plus cloud agents Renamed
Devin Desktop is eighth. The windsurf.com address now redirects to Devin pages, and the product page calls it the renamed Windsurf, built by Cognition. It is a full editor with debugging, diff review and a Kanban board for supervising several agents, plus a handoff to cloud execution for heavy tasks.
- Pricing: Per seat / month + base fee. Free at $0. Free plan: free plan.
- Best for: Teams wanting local plus cloud agents
- Strengths: Agent Command Center; Kanban view of agent tasks; Supercomplete next-edit prediction.
Where it falls short
The rename and move to a new domain make old Windsurf documentation, reviews and contracts harder to match to the current product. The pages we read give no quota numbers, and no self-hosted option appeared.
Wrong for
Buyers who need a documented self-hosted deployment or a stable vendor identity for procurement.
Visit Windsurf (Devin Desktop) →
Bundled with ChatGPT Web, CLI and IDE Credit based
OpenAI Codex is ninth, partly because it is a feature of a broader subscription instead of a standalone developer product. That cuts both ways. A company already paying for ChatGPT Business at $20 per user gets Codex with SSO, MFA and no default data training, with no second vendor review.
- Pricing: Per user / month + credits. Free at $0. Free plan: free plan.
- Best for: Teams already on ChatGPT Business
- Strengths: Web, CLI and IDE extension; Cloud tasks; Code review.
Where it falls short
Usage is metered in credits that vary by model and task, and the page itself says a typical task can use anywhere from 2 to 15 credits, which makes forecasting a monthly bill difficult.
Wrong for
Teams that want a model-neutral tool or an editor-centered workflow, and buyers who dislike credit meters.

#10 Amazon Q Developer
AWS's developer assistant for IDEs and console · United States · aws.amazon.com
AWS native IP indemnity Java upgrades
Amazon Q Developer is tenth. It earns its place on two specifics: code transformation and AWS depth. The pricing page lists 1,000 lines of Java upgrade per month free, and 4,000 pooled lines per user on Pro, with extra lines at $0.003 each, which is a concrete number a platform team can budget.
- Pricing: Per user / month. Free tier with 50 agentic requests per month; Pro is $19 per user per month, adding higher limits, an admin dashboard and IP indemnity. Free plan: free plan.
- Best for: Teams building mainly on AWS
- Strengths: IDE chat and inline suggestions; Command line agent; Security scanning.
Where it falls short
Outside AWS work it has no edge over the other tools. The free tier of 50 agentic requests a month runs out within a few sessions.
Wrong for
Teams not built on AWS, and anyone who needs a generous free allowance for open-ended agent work.

#11 Gemini Code Assist
Google Cloud's coding assistant for teams · United States · codeassist.google
Google Cloud Two editions Daily request quotas
Gemini Code Assist closes the list at eleventh with the least verified detail, which says something about how a buyer meets it. The developer documentation names two managed editions, Standard and Enterprise, and the quota page puts agent mode and the Gemini CLI under one shared daily cap of 1,500 requests per user on Standard and 2,000 on Enterprise.
- Pricing: Per user / month. Sold as Standard and Enterprise editions through Google Cloud. Free plan: none.
- Best for: Teams already on Google Cloud
- Strengths: Agent mode; Gemini CLI; Standard edition.
Where it falls short
The pages we could read did not give a list price per seat, a free plan, or data-training terms, so the buyer must get those from Google in writing.
Wrong for
Small teams that want to see a price and sign up with a card in five minutes, and companies outside Google Cloud.
Visit Gemini Code Assist →
#12 Kiro
Spec-driven agent IDE and CLI from AWS · United States · kiro.dev
Spec-driven Credit metered AWS identity
Kiro takes twelfth place because it is the newest answer to a question the other tools skip: what should the agent be told before it writes anything? Its specs turn a prompt into a requirements file, a design file and a task list, and the documentation adds property-based tests to check behavior beyond a few examples.
- Pricing: Per user / month + credits. Free is $0 with 50 credits a month. Free plan: free plan.
- Best for: Teams that want written specs before code
- Strengths: Spec-driven development; Property-based correctness tests; Steering files.
Where it falls short
Credits are the unit of cost, and a prompt can use less than one credit or many, depending on the model and the task, so a monthly bill is hard to forecast without a trial.
Wrong for
Teams that want an assistant to finish lines inside an IDE they refuse to change, and companies that need European storage on an individual plan.

Questions and answers
What is the best AI coding assistant in 2026?
Zed ranks first of 12, best for developers who want their own keys. Cline is second (teams that want open code and own keys) and Augment Code third (mid-sized teams with large codebases). Places 1 to 3 go to challengers, vendors outside the best-known brands, wherever the category has them.
Is GitHub Copilot still worth it when Cursor and Claude Code exist?
For a team whose repositories and reviews are on GitHub, yes. Its Business and Enterprise plans include IP indemnity, which GitHub says the individual plans do not, and the tool needs little setup.
Which AI coding assistant lets me use my own API keys?
Cline, Zed and JetBrains AI Assistant all document it. Cline is free for individuals and has you pay for inference by usage, with keys from OpenAI, Anthropic, Google, Bedrock and others.
Does an AI coding assistant train on my company's code?
It depends on the plan, not the product name. Anthropic says it does not train generative models on code sent to Claude Code under commercial terms, but consumer Free, Pro and Max accounts can allow training.
Is there a European AI coding assistant?
Only one in this ranking: JetBrains AI Assistant, from JetBrains s.r.o., registered in Prague. It is not European-only in practice, because its terms say instructions are sent to third-party language model providers.
How much does an AI coding assistant cost per developer?
Entry prices cluster between $10 and $40 per month. Zed Pro is $10, GitHub Copilot Pro $10, JetBrains AI Pro $20, Cursor Premium $30, Codex Plus $20, Amazon Q Developer Pro $19 and Cursor Teams from $30 per user.
What happened to Windsurf?
The windsurf.com address now redirects to Devin pages operated by Cognition, and the Devin Desktop page describes the product as the renamed Windsurf.
Can an AI coding assistant run in my own cloud or on premises?
Cline's enterprise page describes deployment in a customer VPC, on premises or air-gapped, with inference going straight to the chosen model provider.
Do I need IP indemnity for AI-generated code?
It matters if your customers or investors ask who is liable when generated code resembles licensed code. GitHub states IP indemnity for Copilot Business and Enterprise but not for individual plans, and Amazon Q Developer Pro lists it too.
Should a small team pick an editor or a plugin?
Pick a plugin or terminal agent when the team already has a standard editor, because it avoids retraining and keeps one set of extensions. Cline, GitHub Copilot, Augment and Claude Code work that way.
What should I watch for when the free tier ends?
Free tiers are small. JetBrains gives 3 credits per 30 days, Amazon Q Developer 50 agentic requests a month, and Copilot 2,000 suggestions.
