Pebrel: GPU-accelerated terminal and SSH workspace for AI CLI work

Pebrel is a GPU-accelerated terminal, SSH workspace, and home for AI CLI sessions. Built with Rust and GPUI for Windows, macOS, and Linux, it combines split terminals, SSH/SFTP, Claude Code and Codex workflows, and native document reading.

Overview

Pebrel (formerly Nebula) is a native desktop workspace that brings local shells, remote hosts, files, and AI command-line tools together. It is built with Rust and GPUI for Windows, macOS, and Linux and arranges terminals in tabs and splits so users can follow agent activity and read output without leaving the application.

Key Features

Terminal tabs and draggable split panes with per-pane working directories and saved workspace layouts.
SSH host management with saved hosts, SSH config aliases, proxy and jump-host options, private-key and keyboard-interactive authentication, host-key verification, and SFTP transfers.
AI CLI workflow support for Claude Code, Codex, and other recognized CLIs, with activity states, notifications tied to source panes, and captured answer reading.
Intelligent completion from Git repositories, project scripts, SSH config, and the filesystem, plus registered WSL distributions on Windows.
GPU-accelerated GPUI interface with light and dark themes, opacity controls, eleven UI language choices, searchable settings, a command palette, and Lua configuration with validation and live reload.
Native Markdown document tabs and mathematical typesetting without a WebView.

Use Cases

Managing local shells and remote SSH/SFTP sessions in one desktop workspace.
Running and monitoring Claude Code, Codex, or other AI CLIs in split panes with notifications and answer reading.
Using intelligent completions for Git branches, npm scripts, SSH aliases, WSL distributions, and filenames.
Reading Markdown documents and formulas natively alongside terminal work.

Getting Started

Choose a package from the latest release.
On Windows, run the installer or extract the ZIP and launch pebrel.exe while keeping the bundled directories together.
On Linux, install the DEB or make the AppImage executable. On macOS, open the matching DMG and drag Pebrel into Applications.
For configuration, run pebrel config init --language en-US and pebrel config check.

Deployment & Requirements

Windows 10 1809+ or 11 on x64; installer .exe and portable .zip packages are provided.
Linux Preview on x64 with glibc 2.35+; AppImage, .deb, and portable .tar.gz packages are provided.
macOS Preview with deployment target 14+ on Apple Silicon/arm64 or Intel/x64; .dmg packages are provided.

Before You Adopt

License: GPL-3.0. Review its terms before using, modifying, or distributing the project.
Restoring an AI conversation after the process exits depends on a supported CLI and a usable session identity.
Image attachment previews for AI CLIs depend on the CLI itself.
