What live-share.nvim is
live-share.nvim is a free, GPL-3.0 Neovim plugin for real-time pair programming and collaborative editing. Participants can share buffer edits, remote cursors, selections, workspace files, and a shared terminal. Guests can browse the host’s workspace, open files, and follow another participant’s active buffer. The host approves each guest and assigns read-only or read-write access. Neovim and VS Code users can collaborate through the compatible open-pair client, with either editor hosting or joining. The default WebSocket transport uses a tunnel provider, while optional punch transport supports direct UDP connections with relay fallback. Session messages use mandatory AES-256-GCM encryption, and OpenSSL is required. Users can configure their own SSH or bore server as a tunnel. The plugin requires Neovim 0.9 or later. Concurrent edits to one line use host-ordered last-write-wins behavior, and reconnecting guests receive a fresh shared terminal buffer without earlier scrollback.
Who it suits
It suits developers doing pair programming, read-only code review, or collaboration between Neovim and VS Code. Teams wanting self-hosted tunnels can configure their own SSH or bore server.
What it does well
- Free and open source
- Read-only or read-write guest roles
- Neovim and VS Code collaboration
- AES-256-GCM session encryption
- Self-hosted tunnel option
What to know first
- Requires Neovim 0.9 or later
- No authentication beyond URL and host approval
- Same-line edits may be overwritten
- Reconnecting guests lose terminal scrollback
Verdict
live-share.nvim provides collaborative editing and terminal sharing directly around Neovim. Its transport choices and encryption are useful, while the editing, authentication, and terminal limitations should be understood first.

- Editor integration
- The project documents tested collaboration with the VS Code extension open-pair in both host and guest directions. · github.com, 9 Oct 2026
- Encryption
- Session messages use mandatory AES-256-GCM encryption, and sessions will not start if OpenSSL is unavailable. · github.com, 9 Oct 2026
- Guest roles
- The host approves each guest and assigns read-only or read-write access. · github.com, 9 Oct 2026
- Key sharing
- The session key is placed in the share URL fragment, which the project says is not sent in HTTP requests to the tunnel server. · github.com, 9 Oct 2026
- Known editing limit
- Concurrent edits to the same line are resolved by host arrival order, so one participant's edit may be silently overwritten. · github.com, 9 Oct 2026
- License
- The project is licensed under GPL-3.0. · github.com, 4 Oct 2026
- Platforms
- The default ws transport is described as tested on Linux, OpenBSD, macOS, and Windows using Git Bash; the optional punch P2P transport is tested on Linux. · github.com, 9 Oct 2026
- Platform support
- The README lists Linux, OpenBSD, macOS, and Windows with Git Bash as tested for ws transport; punch transport is tested on Linux. · github.com, 4 Oct 2026
- Privacy
- The maker says tunnel servers can see connection metadata such as guest IP addresses and timing, but cannot read encrypted session content or obtain the key from the URL fragment. · github.com, 4 Oct 2026
- Purpose
- live-share.nvim provides real-time pair programming and collaborative editing for Neovim. · github.com, 9 Oct 2026
- Requirements
- The plugin requires Neovim 0.9 or later and OpenSSL, and its default ws setup has no external plugin dependencies. · github.com, 9 Oct 2026
- Security limits
- The project states that it has no forward secrecy and that tunnel providers can see connection metadata such as guest IP addresses, timing, and traffic volume. · github.com, 9 Oct 2026

- Support
- The README directs users to troubleshooting documentation and invites issues and feedback. · github.com, 4 Oct 2026
- Sync limitation
- Concurrent edits to the same line use host-ordered last-write-wins behavior, so one edit can be silently overwritten. · github.com, 4 Oct 2026
- Terminal limitation
- A reconnecting guest starts with a fresh shared terminal buffer and does not receive previous scrollback. · github.com, 4 Oct 2026
- Transport options
- The default WebSocket transport uses a tunnel provider, while optional punch transport supports direct UDP connections and relay fallback. · github.com, 4 Oct 2026
- Tunnel providers
