How to Run Claude Code in Parallel (with Tembo)

Claude Code is powerful but also painfully single-threaded. One task at a time means while it's fixing auth, nothing else moves. No docs. No tests. No feedback loop.

That doesn't fly in real product teams.

Parallelism is the baseline

Your CI doesn't run one test at a time. Your engineers don't wait their turn to code. So why are your agents stuck in a queue?

Claude Code was built as a CLI. It doesn't manage compute. It doesn't scale. And it definitely wasn't designed to coordinate multiple agents at once.

That's where Tembo comes in.

Tembo: The missing runtime for Claude Code

Tembo turns Claude Code into a team, not a solo act. Instead of hacking around with tmux or containers, you use app.tembo.io to spin up cloud tasks with full context and proper isolation.

Here's what you get out of the box:

• Run any number of Claude agents in parallel
• Each agent gets its own CPU, memory, file system, and git state
• Integrations (like Linear, Jira, GitHub, Slack) feed data into the context window before the agent runs
• MCP (multi-context processor) stitches together relevant history, state, and metadata so Claude always knows what it's working on
• Track agent output, progress, and status live from a single dashboard

This isn't just automation. It's orchestration.

How it works

Step 1: Connect your tools Start at app.tembo.io and connect your stack:

• GitHub or GitLab for code
• Linear or Jira for task management
• Sentry, Datadog, or your favorite monitoring tool
• Slack, Discord, or email for notifications

Tembo uses these integrations to pull in tasks, issues, and alerts before execution so it's never guessing.

Step 2: Assign tasks to Tembo

If you're using a third-party tracker like Linear or Jira, you assign the issue to Tembo. It picks up the context and starts working.

If you're creating the task directly in app.tembo.io, you don't need to assign anything. Tembo will spin up the environment and kick off work automatically.

Either way: every task runs in parallel.

Step 3: Watch it ship

Tembo handles the entire flow:

• Spins up isolated environments
• Runs Claude with the right context
• Opens a pull request for each task
• Sends results back to your tools or dashboard

PRs like any other engineer would write

Each task Tembo runs results in a pull request. You review it like you would from any dev.

Leave comments? Tembo automatically spins up Claude Code again in the background to address your feedback and re-commit to the same PR.

And with support for AI reviewers, the entire cycle (task → PR → review → merge) can be fully automated.

Why this matters

Claude Code alone is useful. Claude Code in parallel, with full context, running in the cloud, backed by Tembo - that's the real unlock.

You go from:

"Can Claude help?"

to:

"There's already a PR waiting on your review."

Try it now

Claude wasn't built to scale alone. Tembo gives it structure, context, and the ability to ship real work—at real speed.
