Who each one suits
Agent Zero
- Developers who want an agent whose prompts and tools they can inspect and change
- Keeping an agent sandboxed in Docker instead of running it on the host

Hermes Agent
- Developers who want an agent on their own machine, server or VPS
- Reaching one agent from Telegram, Discord, Slack or WhatsApp
- Unattended scheduled jobs such as reports and briefings
Worth knowing
Agent Zero
- The site lists no hosted version: you install it with the Launcher, a terminal installer or Docker on a machine you provide.
- Model access is not included. You connect a cloud provider, an AI account such as ChatGPT or GitHub Copilot, or a local model server.
- The Launcher is offered for macOS, Windows and Linux; the installation page lists no iOS or Android app.
- The project funds itself through its A0T crypto token, not paid plans; a beta LLM API with a daily quota is open only to people who stake A0T.
Hermes Agent
- The agent is free, but paid models cost extra: your own provider's rates, or Nous Portal tiers from $20 a month.
- Desktop apps are offered for macOS and Windows; on Linux the install is through the terminal.
- The platform support page lists no iOS version, and Android runs only through a prerelease Termux package.
- Hermes Cloud needs $2 of Nous credit or an active subscription to deploy, and bills inference separately from the instance.
Key features
Agent Zero
- Linux desktop in a container
- The agent gets an XFCE desktop session inside its Docker container, where it runs terminals, file tools and GUI software. You see each action and share the same mouse and keyboard.
- Browser with annotation
- A built-in browser opens pages, clicks, types, uploads files and takes screenshots. In Annotate mode you click a page element to have it changed, inspected, copied or commented on.
- Document cowork
- A Markdown editor and LibreOffice Writer, Calc and Impress are built into the workspace, so you and the agent edit the same document, spreadsheet or slide deck.
- Projects, memory and secrets
- Projects keep files, instructions, memory, secrets, Git repositories and model presets separate per workspace. A Memory Dashboard is used to review and manage what is stored.
- A0 CLI Connector
- An optional command-line bridge lets a sandboxed instance request access to files, a terminal and a Chromium-based browser on your own computer.
- Plugin Hub, MCP and A2A
- More than 100 community plugins install from the Web UI, each scanned for risks first. The agent also connects to MCP servers and Agent-to-Agent flows.
Hermes Agent
- Messaging gateway
- One gateway connects the agent to Telegram, Discord, Slack, WhatsApp, Signal, Matrix, email, Microsoft Teams and other platforms, more than 20 in all, sharing a single memory.
- Memory and self-written skills
- The agent keeps memory across sessions, creates reusable skills from work it has done and revises them in use. Skills follow the open agentskills.io format.
- Scheduled automations
- Built-in cron accepts natural-language schedules for reports, backups and briefings and delivers the results to any connected platform.
- Subagents
- Isolated subagents with their own conversations and terminals handle parallel workstreams without filling the main agent's context.
- Terminal backends and sandboxing
- Commands run locally or in Docker, over SSH, or on Daytona, Singularity, Modal or Vercel Sandbox, with command approval and container isolation.
- Nous Portal and Hermes Cloud
- A Portal subscription supplies credits for 200+ models and hosted web search, image generation, text-to-speech and browser tools. Hermes Cloud hosts an always-on agent, billed daily.
