AGPL-3.0-only Eligibility checked macOS Windows Linux v0.14.0 · 279 ★ · pushed Aug 18, 2026

Native, open-source SSH client with a local vault

Metadata checked Aug 18, 2026

Why this pick

Closest functional match to Core Shell: it is a dedicated SSH client with vault storage, host organization, forwarding, SFTP, and native macOS packaging. Recent releases are strong, though its community and maturity are smaller than the established alternatives.

A native Rust desktop SSH client combining host management, encrypted credential storage, jump chains, forwarding, SFTP, and split terminal sessions. Current macOS downloads target Apple Silicon.

Key capabilities
  • 01 Native Rust SSH client with encrypted local vault
  • 02 Multi-hop SSH, proxy support, agent forwarding, and port forwarding
  • 03 Built-in dual-pane SFTP, host groups, split panes, and session layouts
  • 04 Imports existing SSH configuration and provides a free macOS Apple Silicon download
Caveats
  • The listed macOS binary is for Apple Silicon; no Intel macOS artifact was found.
  • Younger project with a smaller community and shorter production track record.
  • Optional AI and cloud integrations may involve third-party services; the core SSH client is free under AGPL.

Configurable terminal with an integrated SSH manager

Metadata checked Aug 18, 2026

Why this pick

Best established open-source SSH manager in this set: it covers host profiles, forwarding, jump hosts, SFTP, panes, and plugins, with a large contributor and user community. Its Electron footprint and less Mac-native feel keep it below Oryxis.

Full review — capabilities, 3 caveats, evidence

A cross-platform terminal that includes an SSH connection manager, SFTP, Telnet and serial support, forwarding, jump hosts, panes, plugins, and encrypted configuration storage.

Key capabilities
  • 01 Integrated SSH2 client and connection manager
  • 02 Jump hosts, X11 and port forwarding, agent forwarding, and login scripts
  • 03 Tabs, split panes, serial and Telnet sessions, and SFTP workflows
  • 04 MIT-licensed public releases for Windows, macOS, and Linux
Caveats
  • Electron-based and comparatively resource-heavy.
  • Some useful workflows, including sync and extra SFTP capabilities, are plugin-based.
  • Use the current macOS asset from the latest GitHub release rather than assuming a particular architecture.

Mature macOS terminal for OpenSSH workflows

Metadata checked Aug 18, 2026

Why this pick

Strongest choice for macOS-native polish, long-term maintenance, and community trust. It provides excellent OpenSSH, profiles, Keychain, and session features, but is a terminal replacement rather than a full dedicated SSH connection manager.

Full review — capabilities, 3 caveats, evidence

A long-established macOS-native terminal replacement that wraps OpenSSH with searchable tagged profiles, Keychain integration, split panes, tmux session control, shell integration, and SCP-friendly features.

Key capabilities
  • 01 Native macOS terminal with OpenSSH and profile-based host workflows
  • 02 Taggable, searchable profiles and automatic profile switching by host
  • 03 Password manager backed by macOS Keychain
  • 04 Split panes, tmux integration, session restoration, shell integration, and SCP support
Caveats
  • macOS-only.
  • Current builds require macOS 12.4 or newer.
  • Host organization is profile-based and less specialized than Core Shell's dedicated connection database.
