Core tools and resources maintained by the Gemini CLI team.

• Gemini CLI - The official open-source AI agent that brings the power of Gemini directly into your terminal. Features context-aware coding assistance, file manipulation, and command execution capabilities.
• Gemini CLI cookbook - Official collection of examples and guides demonstrating best practices for using the Gemini API. Essential resource for developers getting started.
• Run Gemini CLI - Official GitHub Action that seamlessly integrates Gemini into your CI/CD pipeline, enabling automated code reviews, testing, and documentation generation.

Alternative user interfaces and frontends for interacting with Gemini CLI beyond the terminal.

• Gemini CLI Desktop - Beautiful desktop and web UI that makes Gemini CLI accessible to non-terminal/mobile users while preserving all its powerful features.
• AionUi - Free, local, open-source GUI app for Gemini CLI — Better Chat UI, File Management, AI image editing, multi-agent support, multi-LLMs & apikey polling, code diff view & more.
• Yaw - Cross-platform terminal that auto-detects Gemini CLI and opens a split-pane workflow with a companion terminal.
• Termly - Free native iOS and Android app to monitor and control Gemini CLI (and other CLI AI assistants) remotely. Zero-knowledge E2E encryption, pairs in under 60 seconds via QR code. No subscriptions, no usage limits.
• Agent Workbench - Local web UI for Antigravity CLI (agy), the official successor to Gemini CLI: tabs, browsable history, conversations as cards, and its status and context meter through the status line. Runs Claude Code, Codex and OpenCode side by side and hands a conversation over from one CLI to another. It doesn't drive Gemini CLI itself; the repository includes a one-off importer for old Gemini CLI chats.
• AnywhereDesign - Local-first voice cockpit and remote mobile interface for Claude Code & Antigravity/Gemini CLI. Control terminal agent sessions from your phone via local QR code, real-time voice dictation, live terminal output streaming, and zero-token mobile Git sync.
• Mobile SSH - Android and iOS (TestFlight beta) SSH client for running Gemini CLI on remote servers, with a Gemini CLI installer plugin, simultaneous terminal sessions, and tmux session management.
• Bellows - Desktop workspace that runs Gemini CLI over ACP alongside Claude and Codex, with diffs, permission prompts, team rules, a hash-linked audit trail and live session sharing. Windows, macOS and Linux.
• Alchemist Coder - Open-source desktop app for Windows, macOS and Linux that indexes your Gemini CLI chats, together with Claude Code, Codex and Grok Build sessions, into one local, read-only full-text search. Running Gemini CLI over ACP inside the app is planned for its upcoming Pro edition; the free edition runs Claude Code and Codex on local models.
• SwarmPane - Desktop app for Mac, Windows and Linux that runs Gemini CLI (with a Gemini API key) side by side with Claude Code, Codex, Cursor Agent, Copilot, Devin and more, up to 16 at once in real terminals, with a git worktree per agent, undo for every agent step and account switching when a usage limit hits. Paid, with a 7-day trial for $1.
• OpenCode Mobile - Independent, unofficial, open-source (MIT) Android app that runs Gemini CLI, with Claude Code, Codex, Qwen Code and other agents, on the phone itself in an Ubuntu environment it installs inside the app, or connects to an agent on your computer. Approve tool requests from a notification or widget, review diffs, preview the dev server. Made by its owner with substantial AI assistance.

Modified versions of Gemini CLI with enhanced features or alternative model support.

• LLxprt Code - An open-source multi-provider (including local) fork of Gemini CLI. Use whatever LLM you want to code in your terminal.
• iFlow CLI - Powerful fork that extends Gemini CLI with repository analysis, context interpretation, and complex workflow automation. Perfect for teams needing advanced orchestration capabilities.

• loopguard - Watchdog that tails Gemini CLI session transcripts and alerts when the agent loops, oscillates, or stalls — Telegram notifications, zero dependencies.
• Ralph Harness - Tiny Python scaffold for running Gemini CLI, Claude Code, Codex CLI, and similar coding agents in guarded local loops. It uses repo-local specs, fresh-context iterations, hard caps, git-hook gates, CI verification, and coverage gates.
• Bernstein - Multi-agent orchestrator that coordinates Gemini CLI alongside Claude Code and Codex CLI. Spawns parallel coding agents from a single goal, verifies with tests, auto-commits. Deterministic Python coordination, zero LLM tokens on orchestration.
• Tars - A local-first autonomous supervisor and sidekick powered by Google Gemini. Features background persistence (heartbeat), tiered local memory, multi-channel notifications (Discord/WhatsApp), and self-healing background services. Designed for reliable, long-running agentic orchestration in the terminal.

• AgentBox - Run multiple coding agents (Gemini CLI, Claude Code, Codex, OpenCode) in parallel, each teleported into its own sandboxed VM — local Docker, self-hosted, or cloud (Hetzner, Daytona, Vercel, E2B, DigitalOcean). Sub-1s checkpoint startup; git credentials stay on the host. MIT.
• DevIntern - Tool that picks up tickets from Jira, Linear, Trello, Asana, Azure DevOps, GitHub Issues, or markdown files and turns them into self-reviewed pull requests by driving Gemini CLI non-interactively (also supports Claude Code, Codex, and others). A feasibility gate flags vague tickets back to the tracker with questions; optional unattended mode schedules ticket pickup and turns PR review comments into commits. Runs on your machines with your own Google keys. FSL-1.1, free for interactive use.
• PickySteve - Skill router and context picker for coding agents: a local model (via Ollama, offline by default) routes each prompt to the right skill via hybrid BM25 + embedding retrieval, cross-encoder rerank, and an LLM judge, then assembles a minimal context bundle for the execution model. Built-in prompt-injection gate scans every retrieved document, fail-closed. Ships an MCP stdio server and an OpenAI-compatible proxy; one-command installer wires 18 coding agents including Gemini CLI. MIT.
• Agentlas OS - Local-first Agent Operation Environment (AOE) that installs into Gemini CLI and other supported hosts to build, route, and run specialist agent teams with portable packages, permissions, and verification gates.
• intentic - Self-hosted workspace that runs Gemini CLI over ACP (gemini --experimental-acp) alongside Claude Code, Codex, and OpenCode.

One list shows every session's live status, prompts go into a pane without attaching, a session can spawn into its own Git worktree, and a full-file diff review sends line comments back to the agent. Launches your installed Gemini CLI unmodified, so login, config and MCP servers carry over. macOS, Linux and Windows via WSL2. Apache-2.0.
