From file or idea to useful app

Publish faster, then keep building with the data you already have.

Publish a page or full static project without assembling a separate hosting workflow
Turn tables and data files into reusable APIs, datasets, dashboards, maps, and portals
Add secure server-side logic for APIs or authenticated site backends with MiniUp Functions
Build authenticated apps with MiniUp members, roles, private site files, and secure Site Functions without setting up a separate backend
Find hosted data across your sites in one Data Catalog and inspect it before building
Approve multiple datasets for one app with Dataset Bundles
Use MiniUp in ChatGPT to move from an upload or hosted dataset to a published app
Control how sites and data are shared with public and protected access options

MiniUp starts with a familiar action: publish the page or upload the file. It then helps you turn that work into a lightweight app with frontend files, hosted data, login, and backend logic in one workspace.

You can build directly in MiniUp or connect it to ChatGPT. Either way, the result is a real MiniUp app that can combine site files, MiniUp Tables or hosted datasets, Site Functions, and members and roles.

Start Publishing → Read FAQs

One workspace, several ways to create

Publish a page

Start from HTML, a folder, a ZIP, or a project created with AI.

Create from a file

Turn a spreadsheet or geospatial file into a dashboard, map, API, or hosted dataset.

Connect a Data Source

Create a refreshable MiniUp snapshot from a supported web file or ArcGIS layer.

Use your Data Catalog

Find owned datasets across sites and review their fields, samples, profiles, and access status.

Approve a Dataset Bundle

Choose the datasets and roles an app is allowed to use before building it.

Build in ChatGPT

Ask for a useful dashboard, map, report, portal, or business app in plain language.

Add a MiniUp Function

Create a hosted API or link a Site Function to your app's members and roles.

Publish and manage

Share the result, update it later, and keep its access settings clear.

Apps for people and agents

Build once. Use it yourself, through an API, or with an AI agent. Enable Agent Actions to let agents safely use the same Tables and Functions with your app’s existing permissions.

Explore Agent Actions →

Build from new files and existing hosted data

MiniUp helps you reuse data instead of starting every app from an empty page.

Start with a new file

Upload a spreadsheet or geospatial file
→ inspect the data
→ publish a dashboard or map
→ keep the hosted dataset available for future apps

Useful for one-off analysis, new reporting, and turning a file into a lasting app.

Start with data you already host

Open the Data Catalog
→ review schema, sample, and profile
→ approve a Dataset Bundle
→ ask ChatGPT to build and publish the app

Useful for cross-site dashboards, linked maps, operational portals, and repeatable reporting.

MiniUp in ChatGPT

For people who already build in chat, MiniUp adds the context and publishing step needed to produce a usable app.

Without MiniUp

You still have to connect the generated idea to real data and a sharing workflow.

Generated pages often stop at a code snippet or local demo.
The AI may have too little context about existing datasets.
Uploaded files may not become reusable hosted data.
You still have to arrange hosting and sharing yourself.

With MiniUp

ChatGPT can inspect approved context and publish the result to your MiniUp account.

Start from uploads or eligible datasets already in your Data Catalog.
Use Dataset Bundles when an app needs several approved data sources.
Get a real MiniUp URL you can open, share, and keep managing later.

See MiniUp in ChatGPT for setup steps and prompt examples.

Why use MiniUp instead of assembling separate tools?

Most publishing tools stop after the first link. MiniUp is designed for the work that happens next.

Upload-only host

You get a live link. Then the stack starts to spread.

Host the page on one tool
Find another tool for discovery or branded sharing
Stand up a separate backend if the page needs focused request logic
Figure out datasets, docs, and updates somewhere else

MiniUp

One workspace can take a project from first publish to a useful data-backed app.

Publish the page instantly
Keep editing files and restoring revisions from the same dashboard
Add Gallery listing, password, QR, and custom domain when distribution matters
Add Table APIs, hosted datasets, Data Sources, and PDF Packs without leaving the workspace
Add hosted API Functions for integrations or Site Members Functions for an authenticated app
Site Functions reuse MiniUp login and roles, so browser code needs no embedded Function API key
Find and approve existing datasets before building the next app

APIs that remember each customer

Keep small JSON settings and preferences between requests, without provisioning a database.

Persistent Function Memory

Shared configuration or private preferences

Use shared memory for Function-wide data and caller memory for each authenticated API key, site member, or verified x402 payer. Preview storage stays separate from production.

Explore methods, limits, and working examples →

Customer integrations

Give each integration its own identity

Create named API keys and rotate secrets while keeping caller identity and stored memory. Site Functions also receive trusted member roles through MINIUP_USER. Organization-level permissions remain part of your application.

Understand callers, tenants, and member roles →

Turn a MiniUp site into a real authenticated app

Build real authenticated MiniUp apps without setting up a separate backend.

The pieces work together

MiniUp site files
+ MiniUp members and roles
+ Site Function
+ MiniUp Tables / private APIs
= authenticated app

HTML, CSS, JavaScript, and components stay in your MiniUp site. Site Access provides login, members, and roles; Invite-only or Private access can require membership before protected frontend files load.

Build an experience for each member

Give your team the right tools and access.

Create a dashboard, customer portal, or internal tool with member-specific navigation and protected data. Keep private credentials in Function Secrets and let your Site Function enforce permissions.

Build an authenticated app with the step-by-step guide →

A Public site stays public even when its Site Members API requires authenticated membership. See the complete member dashboard example for setup and role checks.

Best for

Teams that need dashboards, maps, reports, portals, and lightweight business apps.
People who want to turn uploaded files or hosted datasets into shareable experiences.
Organizations that want a clear catalog of data across several MiniUp sites.
ChatGPT users who want a published result instead of a local-only demo.
PDF manuals, policies, specs, and training documents that need app-ready content.

Not for

Complex back ends with heavy business logic.
Large scale analytics or streaming data.
Highly customized hosting stacks.

Use hosted spatial data to create a map with useful layers, summaries, filters, and linked details.

📦

Directory or records app
