FEATURES

Tools for everyday server administration

Core features bring connections, terminal sessions, files and secure credential storage into one workflow.

SSH client

Connect to Linux and other SSH servers directly from the application. A unified environment makes working with multiple servers easier without constantly switching between separate tools.

SFTP file manager

Work with remote files over SFTP while using an SSH terminal within the same server profile.

Organized server profiles

Store servers in individual profiles and keep the required connection parameters available in one place.

Installable tools

Extend the compact Core with separate plugins for monitoring, SFTP file management, SSH keys, logs, users or NGINX without modifying the base application.

server diagnostics

Probe ICMP, traceroute, DNS, HTTP/1.1/2/3, TLS and TCP without an SSH connection. Live results, local history and JSON/CSV/TXT exports.

Server Diagnostics →

checksum verification

Calculate local file hashes with 49 algorithms, verify expected digests, compare files, and create checksum manifests. Output supports HEX and Base64; file contents and digests are never uploaded.

Guides for specific tasks

Procedures, requirements and limitations for each feature.

SSH client for Windows, macOS and Linux

Connect to a Linux server with an SSH profile, verify its host key and work in the CH-J Server Manager terminal.

SFTP file manager and remote editor

Transfer and edit remote files over SSH using File Manager with save conflict detection.

HTTP/2, HTTP/3 and TLS diagnostics

Check the actual HTTP protocol with the bundled client and inspect TLS 1.2/1.3.

SHA-512, BLAKE3 and file verification

Calculate local checksums, compare files or verify an expected SHA-512 or BLAKE3 digest.

Linux server monitoring over SSH

Inspect CPU, RAM, swap, filesystems, uptime and network interfaces with the System Monitor plugin.

Verify the GPG signature of a download

Before running an installer, check its OpenPGP signature, key fingerprint and complete SHA-512 checksum.

Install on Ubuntu through APT

Set up the signed CH-J Alpha repository on Ubuntu 24.04 amd64 and install Server Manager with APT.

View all questions →

Is CH-J Server Manager free?

Yes. Commercial and non-commercial use of releases under the CH-J Proprietary Software License 1.14 is permitted without license fees indefinitely under its terms.

Which operating systems does it support?

Current Alpha builds target Windows 11 x64, macOS on Apple Silicon (ARM64), and Ubuntu 24.04 LTS x64. Packages currently available are always listed in the Download section.

Where are connections and sensitive data stored?

Profiles, saved SSH passwords and known host keys are stored in a local encrypted vault. The master password is not stored on disk; with key authentication, the private key remains in the local file selected by the user.

How do I update the application?

The application loads an HTTPS catalog of compatible releases for the selected channel. Before using an update package, it verifies the expected size and SHA-512 checksum. Application updates also require a valid detached OpenPGP signature. License acceptance is required again for every new build.
