Instead of running each agent in its own terminal tab and losing track of which one needs approval or which one just finished, Panda Code puts projects, Git, a terminal, a browser, a task board, agent teams, and chat bots into one interface. It doesn’t require an account, a license key, or payment. It uses whatever coding agents and subscriptions you already have installed and logged into.\n\n## TL;DR\n\n- **Panda Code** is a free, open-source desktop GUI that wraps around coding agents you already use, rather than selling you a new model or subscription.\n- It supports **multiple agents side by side** , including Claude Code, Codex, GLM, Kimi Code, Open Code, Mimo, Grok Build, and Antigravity, each with its own model picker and permission settings.\n- The app is built to be **lightweight** , using the system’s built-in web view instead of bundling a full Chromium instance, which keeps memory use and startup time low compared to heavier alternatives.\n- Features like **work trees, agent teams, and a task board** let you run several agents on the same project in parallel without them overwriting each other’s changes.\n- A built-in **browser, terminal, file diff viewer, and mobile simulator support** mean you rarely need to leave the app to check an agent’s work.\n- **Bots** can connect agents to Telegram, Slack, Discord, or WhatsApp so you can send tasks from your phone and review results later on your desktop.\n- Usage tracking shows your **rate limits and estimated costs** across agents, which helps you see how much value you’re getting from a coding plan.\n\n## Seven tools to build an app. Or just Remy.\n\nEditor, preview, AI agents, deploy — all in one tab. Nothing to install.\n\n## How does Panda Code work with existing coding agents?\n\nPanda Code doesn’t replace Claude Code, Codex, or any other agent. It acts as a front end that launches and coordinates them. You install the agents you want to use the normal way (for example, installing Claude Code and logging in as usual), and Panda Code detects and runs them from inside its own window. For agents like GLM and Mimo, you add an API key in settings, and Panda Code uses that key only with its own provider, storing it in your computer’s keychain rather than sending it anywhere else.\n\nThis matters because it means Panda Code has no markup on model usage. If you’re already paying for a Claude plan, a ChatGPT plan, or a GLM coding plan, that’s what gets used. There’s no separate token metering or bundled model access layered on top.\n\nEach task in Panda Code remembers which agent and model you picked for it, and a new task defaults to whatever you used last. The app also shows context window size for each model directly in the picker, which helps when deciding which agent to assign to a job.\n\n## What makes it lighter than other agent GUIs?\n\nThe core design choice behind Panda Code’s speed is using the operating system’s built-in web view instead of shipping its own copy of Chrome. Many Electron-based desktop apps bundle a full browser engine, which adds significant memory overhead and slows startup. Panda Code avoids that, and also avoids running a background Node server.\n\nAccording to the developer’s own testing, the app opens in roughly a third of a second and uses about 130 to 160 MB of memory while idle. By comparison, a similar tool tested alongside it (T3 Code) took around 3 seconds to open and used close to 700 MB. These are the creator’s own benchmarks rather than independently verified figures, but the gap illustrates the architectural tradeoff: a thinner GUI shell means less overhead, at least for a tool whose main job is to orchestrate agents rather than render complex web content.\n\n## How do you install and set it up?\n\nPanda Code is distributed through its GitHub releases page, with three build types:\n\n- A DMG installer for Macs with Apple silicon\n- An installer for Windows\n- An AppImage for Linux\n\nBecause the builds aren’t code-signed yet, your OS will likely flag them on first launch. On a Mac, you need to go into System Settings, then Privacy and Security, and manually allow the app to open. On Windows, you’ll see a SmartScreen warning and need to click “More info” then “Run anyway.” On Linux, you run `chmod +x` on the AppImage before launching it.\n\n## Other agents start typing. Remy starts asking.\n\nScoping, trade-offs, edge cases — the real work. Before a line of code.\n\nAfter installing Panda Code itself, you need Git installed and at least one coding agent set up and logged in (Claude Code, Codex, etc.) before you can start a project. The app checks for its own updates in the background and installs them automatically, but only when no agent is actively running a task, so updates don’t interrupt work in progress.\n\n## What can you actually do once it’s running?\n\nOnce a project is open, Panda Code centers around a prompt box with a model picker, where you choose both the agent and specific model, and a permission mode selector with four levels: standard (asks before risky actions), accept edits (edits files automatically but still asks before running commands), plan mode (read-only, used for planning), and full access (no approval needed). These modes map to each agent’s own built-in permission system rather than adding a custom layer on top.\n\nWithin a conversation, you can reference files with ”@” to search and attach them, or use ”/” to pull up an agent’s slash commands and skills, including custom Claude Code skills. While an agent is working, you can queue up a follow-up message by pressing Enter, or interrupt and redirect it immediately with Command+Enter, a feature that currently works with Claude Code and Codex specifically.\n\nEvery turn’s file changes are tracked individually, with diff views available side by side or inline, and a Git panel lets you stage and commit directly inside the app. A built-in browser can preview local dev servers, let you screenshot a running app and send it to the agent, or display files like SVGs, images, and PDFs without needing an external viewer.\n\n## How does it handle running multiple agents at once?\n\nThis is arguably Panda Code’s biggest differentiator. Several features are built specifically for coordinating more than one agent on the same codebase:\n\n**Work trees** create a separate branch and folder copy of your project for a given task, so one agent’s changes don’t collide with another’s. When a task is done, you can merge its work tree back into your main branch in a couple of clicks, and the app halts the merge automatically if there are uncommitted changes or conflicts.\n\n**Agent teams** let you assign an “architect” model to break a task into parts and distribute them to up to three “worker” agents, which can be different models entirely (for instance, Claude Opus as architect with Codex and GLM as workers). The architect reviews the combined output and reports back with a summary of all changed files. Teams can be saved and reused, so you might keep a cheaper GLM-based team for routine work and a stronger Opus/Codex combination for harder problems.\n\n**The task board** organizes work into pending, in progress, review, and completed columns across all your projects, giving a single view of what every agent is doing.\n\n**Bots** extend this further by connecting an agent to messaging platforms like Telegram, Slack, Discord, or WhatsApp, so you can assign work from your phone and review the results later as a normal task inside the app.\n\n## Is Panda Code worth using?\n\n## Remy doesn't write the code. It manages the agents who do.\n\nRemy runs the project. The specialists do the work. You work with the PM, not the implementers.\n\nFor anyone regularly juggling more than one coding agent, the pitch is straightforward: fewer terminal windows, a shared view of file changes and approvals, and built-in tools (browser, diff viewer, mobile simulators, Git) that otherwise require switching apps. Because it’s free, open source, doesn’t collect data, and doesn’t charge for model access, the downside risk of trying it is low, aside from the usual friction of running an unsigned, early-stage desktop app.\n\nIt’s most useful if you already pay for at least one coding agent subscription and frequently run tasks in parallel or across multiple tools. If you only use a single agent occasionally, the orchestration features (work trees, teams, bots) offer less benefit, and a terminal may be simpler.\n\n## Frequently Asked Questions\n\n### What coding agents does Panda Code support?\n\nIt supports Claude Code, Codex, Kimi Code, Open Code, GLM, Mimo, Grok Build, and Antigravity, using your existing logins or API keys rather than its own backend.\n\n### Does Panda Code cost anything?\n\nNo. It’s free and open source, with no account or license key required, and it doesn’t add any markup to the coding agent plans you already pay for.\n\n### Does Panda Code collect user data?\n\nAccording to its developer, it doesn’t collect data about users, and API keys are stored locally in your system’s keychain and sent only to their respective providers.\n\n### Can Panda Code run agents in isolated environments?\n\nYes.
