Can You Run Multiple Claude Chats at Once?

Short answer: yes, both ways

There are two things people mean by "running multiple Claude chats at once", and both are possible.

• The claude.ai web app: open multiple conversations in separate browser tabs, or use Projects to keep each chat tied to its own files and instructions. Each conversation is independent.
• Claude Code in the terminal: each session is its own process with its own conversation and context, so you can run several side by side on one machine and have them work in parallel.

The rest of this page splits by audience. If you are working in the browser, the next section is for you. If you are coding in the terminal, skip ahead to the developer section, where parallel sessions actually start to pay off.

If you mean the claude.ai web app

On claude.ai, every conversation is independent, so running several at once is just a matter of opening more of them.

Use separate browser tabs

The simplest way is to open claude.ai in a second tab and start a new chat there. Each tab holds its own conversation with its own context, and they do not share memory. You can have one tab drafting an email while another helps you plan a trip, switching between them like any other browser tabs.

Use Projects to keep chats organized

If you keep coming back to the same topic, Projects are a better fit than loose tabs. A Project groups related conversations and lets you attach files and custom instructions that every chat in that Project can see. You can run several Projects at once, each its own workspace, so a chat about your finances does not bleed into a chat about your novel.

That is really all there is to the web app. Multiple chats at once means multiple tabs or multiple Projects. If that answers your question, you are done. If you are actually here about coding in the terminal, keep reading.

If you mean Claude Code in the terminal

This is where parallel sessions get genuinely powerful. Claude Code is the command-line coding agent, and each session you start with claude is its own independent process. It has its own conversation thread, its own context window, and its own working state. Nothing is shared between sessions.

That means you can open a second terminal, run claude again, and now have two completely separate Claude Code sessions running at the same time. One can refactor your auth module while the other writes tests for your API layer. They do not know about each other, and that is exactly what makes parallel work possible.

# Terminal tab 1
cd ~/my-project
claude

# Terminal tab 2 (a second, independent session)
cd ~/my-project
claude

For just two sessions, plain terminal tabs work fine. The friction shows up once you run three or more: you lose track of which tab is doing what, you have to click into each one to check progress, there are no notifications when a session finishes or needs input, and overlapping edits to the same file can catch you off guard. The full breakdown of the free options versus a dedicated tool is in the multiple Claude Code sessions guide.

Where CodeAgentSwarm fits

CodeAgentSwarm is a desktop app built specifically for running parallel AI coding sessions with real visibility. It gives you up to six terminals in one workspace, and it runs on top of your existing subscription, so it is not a model provider. Here is what it adds over a pile of terminal tabs.

• Up to 6 terminals in parallel: run several Claude Code sessions at once, and pick a different agent per terminal if you want to mix in Codex CLI or Gemini CLI.
• Dynamic titles: each terminal shows what its session is doing right now, like "Refactoring Auth" or "Writing API Tests", instead of six identical tabs.
• Desktop notifications: when a session finishes or stops to ask you something, you get a native notification, so you can focus on one terminal and let the rest call you.
• Searchable history: every conversation across all terminals is saved and searchable, so you can trace what a session did yesterday or resume it later.
• Live file diffs: watch the changes each session is making in real time, per terminal and at project level, so overlapping edits are visible before they become a merge problem.

Because every conversation is saved, you can step away from a session and pick it back up later, or go digging through what an earlier chat actually did. The conversation history guide goes deeper on how that history works across parallel sessions. And if you want to run a mixed setup with Claude Code, Codex and Gemini together rather than just multiple Claude Code sessions, the AI CLI agent swarm guide covers that cross-vendor workflow in detail.
