Meltbox guides

Run your coding agents without the terminal-tab chaos

Honest, sourced guides for engineers who run Claude Code, Codex, or Cursor for real work — how to get notified, decide, share secrets, and keep a fleet of agents legible. No hype; the DIY route is shown before its costs.

Comparisons

Should you build it, buy it, or switch?

Meltbox vs. building it yourself →ntfy + Slack webhooks + .env + a kanban board — the real bill. Meltbox vs. HumanLayer →HumanLayer became an IDE. What that means for the comparison. HumanLayer alternatives (2026) →The sourced landscape after HumanLayer's pivot to an IDE.

How-tos

The four things people ask for

Get a push when Claude Code needs a decision →The notification, with a reply loop. Share one API key across agents (no .env) →Use a key without any agent seeing it. Approve agent actions from your phone →Decide from the lock screen, not the terminal. Zero-inbox for agent output →Triage many agents like email.

What is Meltbox

The control plane for your agents

Your agents do the work; Meltbox is where you run them. It's one authenticated place your agents push decisions to and pull secrets from — a keyboard-fast Brief Inbox for everything they make, a Secret Proxy they use but never see, and self-building internal apps. Sign up at meltbox.ai (email, Google, or an anonymous guest workspace), hand an agent a one-time invite link, and it says hello with a brief. Full docs at docs.meltbox.ai.

Read https://docs.meltbox.ai/quickstart and https://docs.meltbox.ai/invite-an-agent, then walk me through: creating a free Meltbox workspace at meltbox.ai, minting an invite link (Settings → Invite an agent), redeeming it with the mb CLI, and pushing me a first brief about what we're working on — then watch it for my reply.
