It combines an **SSH terminal**, **SFTP file browser**, **server monitoring**, **SSH tunnels**, a **multi-engine database client**, an **encrypted password vault** and a **secure [MCP](docs/ai-agents.md) bridge for Claude Code, Claude Desktop, Codex and other AI agents** in a single window — with no account, no telemetry and no subscription. **What makes it different** isn't any one of those — MobaXterm, Termius and the rest each do some of this. It's that they're all in the same place, sharing the same credential store, and that credential store is now also what stands *between* an AI agent and your infrastructure, not something an agent ever has to be handed directly. ## Why OpsMaxx Most terminal tools do one thing. A typical DevOps task needs four: open a shell through a jump host, tail a file, poke a database that is only reachable from inside the network, and look up a credential. OpsMaxx puts those in one place, keeps them organised per project, and stores every secret in your operating system's keychain rather than a plaintext config file. - **No lock-in** — connections import from your existing `~/.ssh/config` - **No account** — nothing about you or your estate is uploaded; the one connection OpsMaxx makes on its own is the update check, on by default and switchable off - **No cost** — MIT licensed, free forever, contributions welcome - **No exposed credentials, even to AI** — Claude Code, Claude Desktop and Codex can run commands and read files through it, but never see a password, private key, IP or username — see [AI Agent Access](docs/ai-agents.md) ## What's in it | | | |---|---| | **SSH terminal** | xterm with GPU rendering, split panes, search, and unlimited chained jump hosts per server | | **Local terminal** | Your own zsh, bash, PowerShell, Git Bash, MSYS2 or WSL in a tab beside the SSH ones — and reachable by no AI agent | | **SFTP browser** | Browse, edit, upload and delete over the same connection | | **Cloud servers** | Google Cloud, AWS and Azure machines through the `gcloud`, `aws` or `az` already on your machine — no cloud credential is stored, and the result is a real SSH session, so files and monitoring work against it too | | **Remote desktop** | RDP to a Windows host, through a bastion when it needs one — with its own account, and no SSH required | | **Monitoring** | Live CPU, memory, disk and network per server, a fleet wall, background checking and webhook alerts | | **Service checks** | HTTP checks against anything you can reach, running whether or not the window is open, with ping and traceroute beside them | | **Tunnels & VPN** | Local, remote and SOCKS5 forwards; userspace WireGuard with no administrator rights; OpenVPN, frp, and **Tailscale and ngrok embedded** — no client to install | | **Databases** | PostgreSQL, MySQL, SQL Server, MongoDB and Redis, direct or through a bastion | | **Containers** | Docker and Kubernetes on a server or on this machine — containers, images, logs and a shell inside one | | **CI/CD** | Jenkins, GitLab and GitHub Actions read beside the server a run changed — pipelines, run history, and the log of the step that failed. Reading only, and off until you turn it on: enabling it polls somebody else's API on a timer with a token you supply | | **Vault** | AES-256-GCM secrets store, with credentials in your OS keychain rather than a config file | | **AI agent gateway** | Claude Code, Claude Desktop and Codex can work through it without ever seeing a password, key, IP or username | → **[The full feature list, what it replaces, and the work it was built for](docs/features.md)** ## Install ```bash brew install --cask opsmaxx/tap/opsmaxx # macOS ``` The tap is third-party, so Homebrew asks you to `brew tap opsmaxx/tap` and trust it first. **Windows** is a direct download for now: the winget manifest is [in review](https://github.com/microsoft/winget-pkgs/pulls?q=OpsMaxx) and community submissions wait on a volunteer moderator, so `winget install OpsMaxx.OpsMaxx` does not work yet. This line will say otherwise the day it does. Download an installer from the **[latest release](https://github.com/OpsMaxx/OpsMaxx/releases/latest)** — `.exe` for Windows, `.dmg` for macOS, `.AppImage` or `.deb` for Linux. → **[Every install route, checksums, and the first-run warning](docs/install.md)** ## Quick start 1. **Add a server** — click **+** in the Connections sidebar, or press Ctrl+N. Authenticate with a password, a private key, an SSH agent or a certificate. 2. **Add jump hosts in the same dialog** — click **Add jump host**; hops connect in order, and each can borrow a saved server's credentials. 3. **Open a session** — click a server. Double-click for a second session in its own tab. Already keep hosts in `~/.ssh/config`? Import them instead of retyping — `ProxyJump` comes across too. → **[The longer walkthrough, with screenshots](docs/install.md)** ## Documentation | | | |---|---| | **[Features](docs/features.md)** | The full list, the comparison with MobaXterm, PuTTY, Termius and SecureCRT, and real-world use cases | | **[Install](docs/install.md)** | Every route for Windows, macOS and Linux, plus the first-run security warning | | **[AI agent access](docs/ai-agents.md)** | How MCP clients reach your infrastructure without seeing a credential | | **[Workspaces](docs/workspaces.md)** | Keeping clients, environments and projects apart, and locking them | | **[Terminal](docs/terminal.md)** | The terminal, the local shell, the command palette and every shortcut | | **[Cloud servers](docs/cloud.md)** | Google Cloud, AWS and Azure through the CLI you already have — and why it brokers rather than wraps | | **[Monitoring](docs/monitoring.md)** | Watching a fleet, and running one change across all of it | | **[Databases](docs/databases.md)** | Five engines, direct or through a bastion | | **[Tunnels and VPN](docs/tunnels.md)** | Forwards, SOCKS5, WireGuard, OpenVPN and frp | | **[Vault and settings](docs/vault.md)** | The secrets store, backups, and the settings worth knowing | | **[Security](docs/security.md)** | How credentials are stored and kept out of plaintext on disk | | **[FAQ](docs/faq.md)** | The questions that come up most | ## Security - Credentials are stored with **Electron `safeStorage`**, backed by DPAPI on Windows, Keychain on macOS and libsecret on Linux — never in plaintext - The vault and backups use **AES-256-GCM** with **scrypt** key derivation - Workspace passwords are stored as **scrypt verifiers** compared in constant time - **Host keys are verified**: unknown servers prompt with a SHA-256 fingerprint, and a changed key is refused outright - **Remote desktop certificates are pinned** the same way — RDP servers are self-signed by default, so a first sighting asks and a change is refused - Shell input is **parsed, never evaluated** — no `eval` on anything you type - The renderer runs with `contextIsolation` on and `nodeIntegration` off, behind a strict Content-Security-Policy Found a vulnerability?
