Hosted Apps From AI Agents: What They Are and When You Need One

A hosted app from an AI agent is a small web tool, such as a dashboard or tracker, that the agent builds and then runs at a web address with its own storage and sign-in. It is useful when several people need something live and interactive, but for most store reporting a scheduled file or summary does the job with far less to maintain.

Concierge doesn't build or host apps. Its agents make files, such as spreadsheets, PDFs and slides, and they share them in the conversation. Here is what hosted apps are, what to check and how to tell which you need.

Viktor's Spaces are one example. Its docs describe a Space as a web app Viktor builds and hosts, such as "a dashboard, an internal tool, a tracker or a customer-facing site", with its own database, sign-in and hosting. There are production and preview versions, and it uses workspace credits based on usage. Internal apps need sign-in, while public ones can be opened without it (checked November 1, 2026).

Other AI app builders follow the same idea with their own limits. The appeal is obvious: you describe a tool in a chat and soon have a link to it.

Before you build anything, look for an existing tool. Most stores already have spreadsheets, Shopify reports and a task tracker, and adding a custom app means adding one more thing to keep working.

• Who can see it: A public link to customer or sales data is a data leak. Confirm the sign-in rules, and check them yourself in a private browser window.
• Who owns the data: It sits in a new database. Ask about backups, deletion and export, and whether it falls under your privacy commitments.
• Who keeps it working: When the person who asked for it leaves, or a data source changes, who fixes it?
• Whether the numbers are right: A polished dashboard looks trustworthy even when its formula is wrong. Check it against a report you already trust.
• What it costs to run: Ask how hosting and usage are charged, and how to turn it off.
• Customer-facing use: Payments, personal data and legal pages need much more review than an internal tracker.

• Who will open this, how often and on what device?
• Could a weekly file or a question to an agent answer the same need?
• Which data does it touch, and could that data appear in the wrong hands?
• Who owns it after launch, and what happens if it breaks?
• How do we retire it?

Say your team wants to track returns waiting on a warehouse check. A hosted app could give them a live list with a status column. A shared spreadsheet could do nearly the same in five minutes, with no new sign-in and nothing new to maintain. A scheduled report could go further in a different way, listing each morning the returns still waiting and how long they have been open.

In many stores, the spreadsheet plus the morning report wins. The hosted app starts to make sense when several people edit it all day, when the spreadsheet keeps breaking, or when you need permissions a sheet can't give. Try the simple version first. You will learn what you really need, and that makes a better brief if you do build something.

Few people plan for this, and it is why old internal tools linger with live data in them. Before launch, write down who owns the app, how to export its data and how to shut it off. Review your apps twice a year. If nobody has opened one in months, export the data and turn it off. Check that any shared links stop working as well.

Concierge has no hosted apps, app builder or public pages for agent outputs. Here is how its agents deliver work:

• Finished files: Spreadsheets, PDFs, Word documents, slides, images and more. The agent builds the file on its own computer and checks it. See files and outputs.
• Recurring results: A scheduled task delivers your report on time, or only when something significant changed.
• Answers on request: Ask in Slack, the admin or the Finn app: "How many orders are late?" You get a current answer, with its work shown.
• Limited access: Only teammates who can see the conversation can open its files.

See data analysis and the daily briefing job. If you really do need an agent to build and host internal tools, Viktor offers that, and our comparison says so. Glossary: agent sandbox.

It is a small web tool that an AI agent builds and runs for you at a web address, usually with its own database and sign-in. Examples include internal dashboards and trackers.

No. Concierge doesn't host apps or public pages. Its agents make files such as spreadsheets and PDFs, deliver them on a schedule and answer questions from your live data on request.

They can be, once you check who can reach them, where the data sits and who maintains them. Test the access rules yourself, and check the numbers against a report you trust.

Use a report unless several people need live numbers or shared editing. A scheduled report is easier to check and has nothing to keep running.
