Code Collaboration Tools: VS Code, Visual Studio and More

To collaborate on code in Visual Studio Code or Visual Studio, you combine two things: Live Share for real-time co-editing and debugging (free, built into Visual Studio 2022 and available as an extension for VS Code), and Git with pull requests on GitHub or Azure DevOps for everything asynchronous. If teammates also need the same running environment, add GitHub Codespaces or Dev Containers. One caveat as of October 2026: Microsoft has put Live Share into maintenance mode, so it still works and is supported but gets no new features.

Which code collaboration tool do you need?

Need	Tool	Works in	Cost (as of Oct 2026)
Pair program or debug together in real time	Visual Studio Live Share	VS Code, Visual Studio 2019 16.9+, browser	Free
Review and merge changes	Git + GitHub or Azure DevOps pull requests	VS Code, Visual Studio	Free tiers; paid plans for larger teams
Same dev environment for everyone	Dev Containers / GitHub Codespaces	VS Code, browser	Dev Containers free; Codespaces free quota then pay-as-you-go
Reach your own machine from anywhere	VS Code Remote Tunnels	VS Code, vscode.dev	Free, single user
Built-in multiplayer editor instead of VS Code	Zed	Zed	See vendor

Most teams use the first two together: Live Share for the hour you spend stuck on a bug with a colleague, pull requests for the code that ships.

How to collaborate in VS Code with Live Share

These steps follow Microsoft's Live Share docs for VS Code.

1. Install the extension. Open the Extensions view (Ctrl+Shift+X / Cmd+Shift+X), search for Live Share (publisher Microsoft, ID MS-vsliveshare.vsliveshare) and install it. VS Code 1.72 or later is required.
2. Sign in. Click Live Share in the status bar, or run Live Share: Sign In from the Command Palette (Ctrl+Shift+P / Cmd+Shift+P). You can use a GitHub account, a personal Microsoft account, or a work/school (Microsoft Entra ID) account.
3. Open the folder you want to share.
4. Start a session. Run Live Share: Start collaboration session (Share). The invitation link is copied to your clipboard.
5. Optional: make it read-only. Click Make read-only in the notification if guests should only watch.
6. Send the link to your teammate over Slack, Teams or email. Only share with people you trust: guests can see your project files and, if you allow it, use your terminals.
7. Guests join by opening the link. They can join in VS Code, Visual Studio, or directly in the browser without installing anything.

What you can do in a session: edit the same files with separate cursors, follow each other, debug together (the guest sees your breakpoints and call stack), share a terminal, and share a local server (for example localhost:3000) so the guest can open your running app.

Two settings worth knowing:

{
  "liveshare.guestApprovalRequired": true
}

This makes you approve each guest before they join. To hide or exclude files from guests (for example .env), add a .vsls.json file to the project root. By default Live Share already hides files listed in .gitignore.

{
  "$schema": "http://json.schemastore.org/vsls",
  "gitignore": "exclude",
  "excludeFiles": ["*.env", "secrets/**"]
}

How to collaborate in Visual Studio

Microsoft's Live Share docs are written for Visual Studio 2022 (minimum: Visual Studio 2019 16.9). Live Share is installed with any workload; you will see the Live Share button in the top-right corner of the IDE (install guide).

1. Sign in to Visual Studio with your Microsoft account, or pick a GitHub account under Tools > Options > Live Share > General > User account.
2. Open your solution and click Live Share. The invite link is copied.
3. Your colleague opens the link in Visual Studio, VS Code, or a browser.

Visual Studio guests get co-editing and co-debugging for C#, C++, Python, JavaScript/TypeScript and more; project-wide IntelliSense for guests is strongest for C#, C++ and JS/TS, according to Microsoft's platform support table. Live Share does not share your screen or desktop windows, so for UI work in WinForms or WPF apps you still need a screen share.

Asynchronous collaboration: Git and pull requests in the editor

Real-time sessions are the exception. Day-to-day collaboration happens through branches and pull requests.

In VS Code

• The built-in Source Control view (Ctrl+Shift+G) handles branches, staging, commits and sync.
• Install GitHub Pull Requests (GitHub.vscode-pull-request-github) to create, review and comment on PRs and issues without leaving the editor. Azure Repos users can use Git in the same Source Control view and review PRs on the web.

In Visual Studio

• The Git menu and the Git Changes window cover branching, commits, push/pull and merge conflicts.
• Visual Studio connects to GitHub and Azure DevOps accounts, so you can clone, push and work with pull requests from the IDE.

A minimal team workflow that works for most teams:

git switch -c fix/login-timeout
# ...edit, test...
git commit -am "Fix login timeout on slow networks"
git push -u origin fix/login-timeout
# open a pull request, request a reviewer, merge after CI passes

Protect main with required reviews and status checks so nothing lands without a second pair of eyes. New to Git? Start with open source version control for beginners.

Share the environment, not just the code: Codespaces and Dev Containers

"Works on my machine" is a collaboration problem too. A devcontainer.json in the repo gives everyone the same tools and versions:

{
  "name": "web-app",
  "image": "mcr.microsoft.com/devcontainers/typescript-node:22",
  "forwardPorts": [3000],
  "postCreateCommand": "npm ci",
  "customizations": {
    "vscode": { "extensions": ["dbaeumer.vscode-eslint"] }
  }
}

With the Dev Containers extension, VS Code opens the project inside that container locally (Docker required). GitHub Codespaces runs the same definition in the cloud and opens in VS Code or the browser. As of October 2026, personal GitHub Free accounts include 120 core hours (60 hours on a 2-core machine) and 15 GB of storage per month; beyond that a 2-core machine costs $0.18 per hour (Codespaces billing). For self-hosted or cheaper options, see our list of free GitHub Codespaces alternatives.

Remote Tunnels is a different thing: running code tunnel on a machine lets you reach it from any VS Code or vscode.dev, but Microsoft notes a tunnel is "designed to be accessed by one user or client at a time" (Remote Tunnels docs). Use Live Share, not tunnels, for working together.

Collaboration tools for developers beyond VS Code

Not everyone on a team uses Visual Studio or VS Code, and code collaboration is more than co-editing. The tools developers actually use to work together, as of October 2026:

Tool	Type	What it's for	Status and cost (Oct 2026)
GitHub pull requests, Issues, Codespaces	Repo hosting + review	Code review, CI checks, planning, cloud dev environments	Free tier; paid plans per user
GitLab merge requests, Web IDE	Repo hosting + review	Same jobs as GitHub, with built-in CI/CD; self-hostable	Free tier; paid plans per user
JetBrains Code With Me	Real-time co-editing in IntelliJ IDEs	Pairing in IntelliJ IDEA, PyCharm, Rider etc.	Being retired: unbundled into a plugin in 2026.1, public relays shut down in Q1 2027
Zed	Editor with built-in multiplayer	Shared projects, channels with voice chat, live cursors	Actively developed
Tuple	Pair programming app	Low-latency screen sharing with remote control, any editor	$30 per user per month, 14-day trial; macOS and Windows, Linux in alpha
Slack, Microsoft Teams, Discord	Team chat	Discussion, PR and CI notifications, quick calls	Free tiers; paid plans
Jira, Linear, GitHub Projects	Issue tracking	Planning and tracking what gets built	Free tiers; paid plans

How they fit together: the Git host (GitHub or GitLab) is the source of truth, chat is where questions get answered and notifications land, an issue tracker holds the plan, and a real-time tool (Live Share, Zed or Tuple) covers the occasional pairing session. If your team pairs in JetBrains IDEs, plan your move off Code With Me before the Q1 2027 shutdown: a screen-sharing pair tool like Tuple works with any editor, and JetBrains points remote-access users to its remote development features.

Limitations to know before you rely on Live Share

• Maintenance mode: no new features are planned. Existing features are supported, but do not expect fixes for edge cases in new language extensions.
• Guests depend on the host: if the host's machine sleeps or disconnects, the session ends.
• Extension gaps: some language features and debuggers are host-only; check the platform support table for your stack.
• Security: a guest with write access can edit any shared file and run commands in a shared terminal. Use read-only mode and guest approval for anyone outside your team.

If your team wants an editor where multiplayer is a first-class, actively developed feature, Zed has built-in real-time collaboration with shared projects and channels. More editors are in our IDE directory.

FAQ

How do I collaborate on Visual Studio Code?

Install the Live Share extension, sign in with GitHub or Microsoft, open your folder and run Live Share: Start collaboration session. Send the copied link; your teammate joins from VS Code, Visual Studio or a browser. For ongoing work, use Git branches and pull requests with the GitHub Pull Requests extension.

Is Live Share still supported in 2026?

Yes. As of October 2026 Microsoft lists Live Share as in maintenance mode: existing features remain available and supported, but no new features are planned.

Is Visual Studio Live Share free?

Yes. The Live Share extension for VS Code and the Live Share feature in Visual Studio are free to use. You only need a Microsoft or GitHub account to sign in.

What are the best collaboration tools for developers?

For most teams: Live Share for real-time pairing and debugging, plus GitHub or Azure DevOps pull requests for code review. Add GitHub Codespaces or Dev Containers if onboarding and environment drift slow you down. Teams on mixed editors often add Tuple for pairing and Slack or Teams for chat.

Can two people edit the same file in VS Code at the same time?

Yes, with Live Share. Each person has their own cursor, theme and keybindings, and edits appear for everyone in real time. Without Live Share, VS Code has no built-in multi-user editing.
