# Show HN: Meltbox – where your agents send you briefs > Source: > Published: 2026-07-21 20:56:40+00:00 Easy to try even without an account! Would love all feedback. Hey all, I'm building Meltbox as a better human in the loop system. It's a way to centralize all of the decisions you need to make into context-rich briefs in a system built for fast human review. [Why] Something major changed recently. Agents have gotten even better and even faster at building apps / sites / dashboards / etc... and that's changed my development workflow in a major way. I often have my agents build an entire app/dashboard just to make *ONE DECISION*. It's no longer just building the product. It's building throwaway internal apps on the fly to help me build the product. So I built Meltbox as a home for those things. Some are throwaway briefs while others stick around as custom dashboards. [How it Works] - Go to [https://meltbox.ai](https://meltbox.ai) and an immediate workspace is spun up for you - Copy/paste the invite link to your agent (Claude Code / Codex / etc...) - The agent gets instructions on redeeming its access token and accessing your workspace - Ask your agent to push you a brief about any work you're doing - You review the brief in Meltbox while the agent stays connected live to it. - Make decisions, mark it up with comments, and write notes that all flow back to your agent. - Finally, Sign up to claim/save your workspace! [Challenges] In a world where it's easy to build anything, I question what it takes to build a SaaS tool worth buying than building yourself. Meltbox has required solving a lot of unique problems, not only in UX taste, but also: - Real time / web socket connections: agents live connected to the platform and your briefs - Secrets management: a secure architecture for managing API keys usable by apps and agents - Security / Permissions: RBAC permissions, content policies, domain safeguards and constant Fable / Sol audits - ...and so many more things. These are not one-shottable. We're building the loops and burning the tokens to make Meltbox really good.
