Your team is already building with AI.

The hard part is everything after: where it lives, who can open it, whether it's safe.

So we built the place that was missing. 👻 #buildinpublic

That's who we build White Ghost for → https://t.co/y4CYCgHEfB

AI made building cheap. It didn't make taste cheap.

Every vibe-coded app now looks the same: the same gradient, the same cards, the same "Get started" button.

The person who knows the problem still has to decide what good looks like. That part doesn't automate. 👻

Most AI-built apps have the same security model: whoever has the link.

That's fine for a demo. It's not fine for your sales numbers.

On White Ghost, you decide who gets in: your workspace, the people you invite, or anyone. 👻 #ClaudeCode

[Daniel Castrillon @DanielCastri1]

At Melonn, everyone started building their own tools with AI.

Quote calculators. Dashboards. A contract reviewer.

Then every tool ended up somewhere different. Passwords everywhere.

So we built the place that was missing. 👻 #buildinpublic

Pushing AI adoption inside a company is the easy part.

The hard part comes a few months later: dozens of apps, workflows and dashboards spread across different services, passwords pasted everywhere, and nobody sure what's running where.

That mess is why we built White Ghost. 👻

@denicmarko Express and Flask... Cause they are light and easy to use in a lambda function for example...

[Daniel Castrillon @DanielCastri1]

@hussain_thaj Damn... I've been using the same. Cool!
