Show HN: Meltbox – where your agents send you briefs
meltbox.ai
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 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.
