Who it is for
People who produce one-off tools, dashboards, or map pages from data and need them hosted somewhere.
Overview
What MiniUp does
MiniUp publishes web apps that require no build step, whether single page or genuinely multi-page, from files produced in the conversation or from data uploaded into it. A CSV or a GeoJSON attachment can end up as a working page with its own URL.
Data hosting is a second half of the product. Datasets can be stored in queryable form, exposed through lightweight table APIs, and published at URLs that ArcGIS clients are able to consume.
After publishing, the app still has work to do. Existing sites, uploaded files, gallery listings, individual records, and datasets can all be managed from the same conversation, so maintenance falls inside the scope along with the initial launch.
What stands out
Dataset hosting with ArcGIS-compatible URLs sits next to page publishing, which is uncommon for a lightweight hosting tool.

Where MiniUp is listed
MiniUp is listed in the ChatGPT apps directory only. HNguyen has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

This is an independent catalogue entry compiled by Node8 from MiniUp's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with HNguyen, and inclusion here is not an endorsement.
