Plugins & Marketplace

Lumide supports third-party extensions running in isolated subprocesses.

Process-Isolated Architecture#

Plugins run out-of-process and communicate with Lumide over JSON-RPC 2.0:

  • Zero Input Lag: Background computations and network calls in plugins cannot freeze the editor or degrade typing responsiveness.
  • Fault Tolerance: A crashed plugin process terminates cleanly without crashing the IDE.

The Marketplace Panel#

Plugin manager on the Marketplace tab, with the plugin list and the selected plugin README
  • Shortcut: Cmd + Shift + X (macOS) / Ctrl + Shift + X (Windows/Linux).
  • Click the + (Add Pane) button on any dock group header and select Plugins.
  • Or run Plugins: Open Marketplace from the Command Palette.

Browsing & Installing#

  • Search: Filter extensions by keyword, author, or language tag.
  • Inspect: Review README, version changelogs, and requested permissions.
  • Install: Click Install to download and launch the extension.

Open a file that an official plugin supports, such as a .php file or Cargo.toml, and Lumide offers that plugin in a notification at the bottom right. Some plugins are offered by what a file holds rather than its name: Flutter for Dart code that imports Flutter or a pubspec.yaml that depends on it, and Tailwind CSS for stylesheets using its directives, a package.json listing it, or a page loading it from its CDN. The notification stays until you answer:

  • Install: installs the plugin, as the marketplace does, starts it for the files already open and says when it's done.
  • Don't ask again: never offers that plugin again.
  • ×: not now; it isn't offered again until you restart Lumide.

Lumide doesn't offer a plugin you've already installed, even one you've disabled. Turn the offers off with Plugin Recommendations (general.plugin_recommendations) in Settings → Plugins.

Managing Plugins#

Inside the Installed tab:

  • Toggle: Temporarily enable or disable a plugin.
  • Settings (⚙): Configure plugin-specific options.
  • Uninstall: Remove the plugin package and delete its cached assets.

Security & Permissions#

When a plugin requests access outside its sandbox (e.g. arbitrary filesystem access, external network connections, or shell commands), Lumide displays a security prompt requiring explicit user authorization. Permissions can be reviewed and revoked at any time under Settings -> Plugins -> Permissions.

Built-In Plugins#

Some of Lumide's own features are built-in plugins. Turn any of them off in the Plugins pane's Installed tab to hide its commands, panes and settings.

  • Vim Mode (vim): Edit with Vim's modes, motions, operators, registers and : commands.
  • Git (git): Branches, changes, diffs and blame in the editor, file tree and status bar, plus the C.O.R.G.I. Git client.
  • Terminal (terminal): Shells in the bottom pane, restored when you reopen the workspace.
  • Project Search (project_search): Find and replace text across every file in the workspace.
  • Remote SSH (remote_ssh): Open folders on other machines over SSH. Files, terminals, Git and language servers run there.
  • Sharing (collaboration): Edit together with people on your network, or anywhere through a relay. Share terminals and follow each other.
