tabby-ssh-keymap

A Tabby plugin that lets your SSH profiles reference private keys by name instead of by absolute file path — so the same synced Tabby config works on every machine, and moving a key is a one-line edit.

Why

Tabby's SSH profiles store private keys as absolute local URIs:

privateKeys:
  - file:///home/alice/.ssh/id_work

This creates two problems:

• Sync across machines breaks. /home/alice/.ssh/id_work doesn't exist on your macOS laptop or your Windows desktop. Every profile referencing that path fails when you sync the config.
• No single source of truth locally. Rotating a key, renaming a file, or reorganizing ~/.ssh/ means editing every profile that points to it.

How it works

Profiles store a logical name that is safe to sync:

privateKeys:
  - sshkey://work

Each machine keeps its own local keymap file (never synced) that resolves work to the actual path on that machine:

// Linux
{ "keymap": [{ "name": "work", "path": "/home/alice/.ssh/id_work" }] }

// Windows
{ "keymap": [{ "name": "work", "path": "C:\\Users\\Alice\\.ssh\\id_work" }] }

Same sshkey://work in the synced config; each machine maps it to its own layout. Rotate a key or move a file? Edit one line in the keymap — every profile referencing that name follows automatically.

Install

From Tabby: Settings → Plugins → Available, search ssh-keymap, click Get, restart Tabby.

Or manually:

cd ~/.config/tabby/plugins   # %APPDATA%\tabby\plugins on Windows
npm install tabby-ssh-keymap

Use

1. Open Settings → SSH Keymap
2. Add an entry: logical name + path to the private key (paths starting with ~/ are expanded)
3. Edit an SSH profile, click Add a private key, pick SSH Keymap in the selector, pick your entry
4. Your profile now references sshkey://<name> and will resolve it locally at connection time

Key features

• Scan profiles: one-click migration of all existing file:// entries in your current SSH profiles to sshkey://
• Cascade rename: rename a key; all referencing profiles are updated automatically
• Key validation: test button that parses each key with russh to verify its format
• Home expansion: paths like ~/.ssh/id_work expand to $HOME/.ssh/id_work at resolution time
• Search & usage count: filter entries and see how many profiles reference each key
• Backward compatible: existing file:// paths in profiles keep working unchanged

Storage

The keymap is stored as ssh-keymap.json alongside Tabby's config.yaml:

• Linux/macOS: ~/.config/tabby/ssh-keymap.json
• Windows: %APPDATA%\tabby\ssh-keymap.json

When Tabby's config sync is enabled, this file is never included in the sync.

Development

git clone https://github.com/mathys-lopinto/tabby-ssh-keymap.git
cd tabby-ssh-keymap
yarn install
yarn watch

In a second terminal, with your Tabby source checkout:

TABBY_PLUGINS=/path/to/tabby-ssh-keymap yarn start
