Which VS Code agent fits you?
Pick what matters most to see the right starting choice.
Both are open source and free. You add your own API key and pay only for model usage. GitHub Copilot’s free tier is another no-cost way to try agent mode inside VS Code.
Claude Code is the most installed agent here and the one we reach for on hard, multi-file work. Pair it with AI agent developers who ship with it daily.
Augment’s context engine maps your whole repo, so its agent pulls only the slice a task needs. That is the edge on large, legacy codebases where other agents lose the thread.
The tool is easy. The judgment to drive it well is not. We match you with AI and machine learning engineers in about 24 hours. Tell us what you need.
1. GitHub Copilot
GitHub Copilot is the most widely used AI developer tool, and it lives right inside VS Code through the Copilot Chat extension. Its agent mode turned Copilot from autocomplete into a real agent. It reads your codebase, edits multiple files, runs terminal commands and tests, and fixes its own mistakes in a loop until the task is done.
At GitHub Universe in late 2025, GitHub launched Agent HQ. It adds Mission Control, a single place to assign and track many agents working in parallel. It adds Plan Mode, where the agent asks questions and writes a plan before it codes. It also opens the door to coding agents from Anthropic, OpenAI, Google, and others, all running inside your subscription. You set lasting rules for the agent in a source-controlled AGENTS.md file.
Pricing starts free, with 2,000 completions a month and limited agent use. Pro is $10 a month, Pro+ is $39, and Business is $19 per seat. One note for 2026. GitHub paused new sign-ups for individual paid plans in April and moved everyone to usage-based billing with monthly AI credits in June. The free tier and business plans still onboard new users.
- Install the GitHub Copilot Chat extension from the VS Code Marketplace.
- Sign in with your GitHub account and start on the free tier.
- Open the Chat panel and switch the mode dropdown to Agent.
- Give it a task, then review and approve its file edits and commands.
2. Claude Code
Claude Code is Anthropic’s agentic coding tool. Its VS Code extension is the most installed agent on this list at 17.7 million installs. It runs as a panel you dock in the sidebar. It shows every file edit as a side-by-side diff you approve before it applies. The extension and the terminal share the same history, so you can move between them on one task.
Two features make it strong on hard work. Plan mode opens the agent’s plan as a markdown document, and you add inline comments before any edit happens. It also supports MCP and subagents, so it can pull in outside tools and split a big task into parts. We reach for Claude Code on large refactors and multi-file changes where a smaller agent loses the thread.
Access comes with a Claude plan or the API. Claude Pro is $20 a month, Max is $100 or $200, and the API is pay as you go. You sign in with your subscription, so no API key is needed for the extension. For more on the model tiers, see our breakdown of Claude Fable vs Opus vs Sonnet.
- Install Claude Code for VS Code from the Marketplace (publisher Anthropic).
- Sign in with a Claude Pro, Max, Team, or Console account.
- Open the panel, type a task, and use Plan mode for anything large.
- Review each diff and approve, reject, or edit before it applies.
3. Cline
Cline is an open-source autonomous agent that runs in VS Code, with 4.3 million installs. It is free under the Apache license. The big draw is control. You bring your own API key from any major provider, including Claude, GPT, Gemini, and local models, so you see and own every cost.
Cline’s Plan and Act modes are the model many other agents copied. In Plan mode it reads and reasons without touching files. In Act mode it executes, and you approve each step or flip on auto-approve for autopilot. It supports MCP, so you can connect databases, APIs, and custom tools. There is no lock-in and no markup. You can also buy inference credits through Cline at cost if you prefer not to manage a key.
- Install Cline from the VS Code Marketplace (publisher saoudrizwan).
- Add an API key from your provider, or buy Cline credits at cost.
- Start in Plan mode to agree on an approach, then switch to Act.
- Approve each step, or enable auto-approve once you trust the task.
4. Kilo Code
Kilo Code is an open-source agent for VS Code and JetBrains, with 1.2 million installs. It started as a superset of Cline and Roo Code and pulls the best of both into one tool. It gives you access to more than 500 models, including the latest from Anthropic, OpenAI, and Google, all from one open-source agent.
The standout feature is automatic model routing. Kilo sends planning, coding, and debugging to the right model for each step, based on a tier you choose, so you control spend without micromanaging it. It has specialized modes like Architect, Code, and Debug, plus an MCP marketplace to add tools. You pay with your own key at no markup, use the pay-as-you-go Kilo Gateway, or take a Kilo Pass from $19 a month.
- Install Kilo Code from the VS Code Marketplace (publisher Kilo Code).
- Connect your own API keys, or top up the Kilo Gateway.
- Pick a model tier and let auto routing place each task.
- Use Architect mode to plan, then Code mode to build.
5. Augment Code
Augment Code is an AI platform for VS Code built for large, complex codebases. It has 762,000 installs and a clear focus. Its context engine maps your whole repository by structure, not keyword search, so the agent pulls only the slice a task touches. That is the edge on big or legacy code where other agents get lost.
Augment’s agent breaks a request into a plan and builds each step, editing across the workspace and using the terminal. It also runs Remote Agents for work that continues in the background, and connects to more than 100 tools through MCP. Smart Apply lets you accept a suggested change with one click. Pricing is $100 a month for the Business plan, which pools usage across up to 50 seats, with Enterprise priced on request. There is no free tier today.
- Install the Augment extension from the VS Code Marketplace.
- Sign in and let it index your repository once.
- Open the agent with the sidebar icon or Ctrl/Cmd+L.
- Describe the change and review the plan before it runs.
6. Tabnine
Tabnine is one of the oldest names in AI coding, and in 2026 it is a full agentic platform, not just autocomplete. It runs in VS Code and has 9.6 million installs. Its focus is privacy and control, which makes it a common pick for banks, health firms, and other teams with strict rules.
Tabnine now ships an agent plus specialized agents for code review, testing, documentation, and fixes, along with a command-line tool. It offers zero code retention and can run as SaaS, in your private cloud, on-premises, or fully air-gapped. You can switch models or connect your own private model endpoint. Pricing is $39 per user a month for the Code Assistant plan and $59 for the Agentic plan. New users now sign up through these paid plans, since the old free tier is being phased out.
- Install Tabnine from the VS Code Marketplace.
- Sign in and pick a model, or connect your own endpoint.
- Choose a deployment that fits your privacy rules.
- Open the agent and assign a coding or review task.
7. Qodo Gen
Qodo Gen, formerly Codium, is an agent that pairs code generation with strong code review and testing. It runs in VS Code with 880,000 installs. Where most agents focus on writing code, Qodo also focuses on code integrity, catching bugs and breaking changes before they ship.
Qodo Gen has an agentic mode that breaks a task into steps and can run code and tests in the IDE through an MCP terminal tool. Its review agent flags bugs, breaking changes, and security issues, with one-click fixes. It also finds and runs missing tests on your changes. It supports MCP and multiple models, including Claude and GPT. Pricing is a 14-day trial, then a credit-based Teams plan around $30 a month, with Enterprise on request. Open-source projects can apply for free access.
- Install Qodo Gen from the VS Code Marketplace (publisher Codium).
- Sign in and start the 14-day trial.
- Use Agent mode to build, then run the review agent on your diff.
- Accept one-click fixes and let it generate missing tests.
The 2026 shakeout: agents that are winding down
The VS Code agent market consolidated fast this year. Several popular tools are gone or changing, so we left them off the list above. Knowing this saves you from starting on a tool with no future.
- Roo Code shut down on May 15, 2026. Its repo is archived and roocode.com now points to a new cloud project. The team said it does not believe IDEs are the future of coding.
- Continue was acquired by Cursor in mid-2026. Its open-source repo is read-only and its hub is winding down.
- Amazon Q Developer stopped taking new sign-ups in May 2026, with IDE support ending in 2027. AWS is moving users to a new tool called Kiro.
- Gemini Code Assist for individuals stops serving its VS Code extension on June 18, 2026. Google is moving people to its new Antigravity product. The paid business editions continue.
The lesson is simple. Pick an agent with clear momentum and a healthy install base. The seven above all fit that test today. For a wider look at AI editors, including separate apps like Cursor and Windsurf, see our guide to the top IDEs for AI coding.
The tools will keep changing. Four well-known agents wound down in a single year. The need for engineers who can pick the right tool, drive it well, and check its output will not change. That is the skill that turns an AI agent into shipped software.
Build with the right agent and the right team
VS Code now has seven strong AI agents to choose from. Start free with Cline or Kilo Code, use Copilot if you live in VS Code, or reach for Claude Code on the hardest jobs. The agent gets you part of the way. The team that builds with it ships the rest. We match you with pre-vetted senior engineers across Asia in about 24 hours, with no upfront cost and payroll handled.
