Practical approaches that scale from 5 servers to 500.
When you manage a handful of servers, remembering hostnames works. When you hit 20, 50, or more, you need a system. The right approach depends on your scale, your team, and whether you work alone or share access.
SSH connections accumulate. A staging server here, a production database there, a jump host, a few developer VMs. Before long you are juggling hostnames, ports, usernames, and key files. The knowledge lives in your head, in scattered notes, or in a config file that has grown unwieldy.
The real cost is not just finding the right connection - it is the context around it. Which server runs which service? What is the database URL on staging vs production? What was that one-liner you ran last month to check disk space on the app servers?
The simplest approach. Define host aliases in your SSH config file:
Host staging-app
HostName 10.0.1.42
User deploy
IdentityFile ~/.ssh/staging_key
Port 22
Then connect with ssh staging-app. This works well for small setups. You can version-control the config file (minus sensitive values) and share it with teammates.
Scales to: ~30-50 hosts before the file becomes hard to navigate. You can use wildcards and includes to organize, but there is no search, no tagging, and no GUI.
Tools like Termius, Royal TS, or MobaXterm provide a GUI for managing connections. You organize them into folders or groups, store credentials, and connect with a click. Termius adds cloud sync and mobile apps.
The trade-off is running a separate application alongside your terminal. You manage connections in one tool and work in another. Some people prefer this separation; others find the context switching costly.
Scales to: Hundreds of connections. Team sharing via the tool's built-in sync.
This is the approach yaw takes. Your server list lives inside the terminal itself - no external app, no browser tab, no separate credentials vault. Save each connection with a name and tags, pull it up from the command palette, and stored credentials stay on your machine behind AES-256-GCM encryption.
For fleet work, a few features matter: broadcast mode types into every open pane at once (rolling restarts, log checks); saved commands with {{variable}} placeholders reuse workflows across environments; color-coded profiles separate prod from staging visually. Tailscale nodes are auto-detected so you connect by hostname. SSH and five database engines (Postgres, MySQL, SQL Server, Mongo, Redis) share the same connection manager, and yaw connect <name> gives you CLI access without opening the GUI.
For large-scale infrastructure, tools like Ansible, Terraform, or AWS SSM Session Manager handle SSH access programmatically. Connections are defined in inventories or infrastructure-as-code, and access is managed through IAM roles or bastion hosts.
This is the right approach for large teams with dedicated DevOps. But it does not replace the need for quick, interactive SSH access when debugging or exploring.
Individual SSH management is one problem. Team SSH management is another. How do you share connection definitions without sharing credentials?
