Show HN: The Box – Run multiple Claude CLI agents in parallel in the cloud
the-box.devHey HN,
I'm a solo developer and kept running into the same problem: I'd want Claude CLI to work on multiple tasks at once, but locally I could only run one instance at a time. So I built The Box.
It lets you spin up isolated sandbox environments in the cloud and run Claude CLI agents in parallel. You write the prompt, pick a GitHub repo, and it handles the rest – creates a branch, does the work, and opens a PR.
The core workflow: - Connect your GitHub repos - Create tasks with prompts - Claude CLI runs in isolated sandboxes - Get notified when done (browser push or Telegram) - Review and merge PRs
Tech stack: Go (Fiber) for backend services, Next.js for frontend, PostgreSQL, Redis for signaling, RabbitMQ for task queue. Workers run Claude CLI in Docker containers.
Currently free to use (with limits) while I finish payment integration. Would love feedback from anyone who's tried to scale their AI coding workflow.
What is the technology you're using for the sandboxing?
Looks pretty! But how is this any different from claude.ai/code (web)?
cheaper?
imo this tool should sell as software runnable in corp's own cloud account
