Frequently asked questions

No. Use either or both. The script covers traffic and browser errors; a metrics endpoint adds your app's own numbers. Uptime checks work with neither.

The script doesn't run on localhost, 127.* or .local pages, so test on the real domain. Also check that the domain is in the site's hostname list, and that an ad blocker isn't blocking the script. The first-party proxy helps with ad blockers.

Yes. Add every hostname (for example with and without www) to the project's settings. Events from hostnames no project lists are dropped, and the Connections tab tells you about them.

Yes. Add it as its own project with its staging hostname. Its events count there even when the staging build carries your production tag, as long as both projects are in the same workspace and no other project lists that hostname.

Yes. Add an API's address and it gets uptime checks, on its health check when it has one. A cron job, backup or worker without an address is added as a scheduled job: it requests a secret ping URL after each run, and you're alerted when a run fails or doesn't arrive. See APIs and scheduled jobs.

Mosaicdeck generates it from what the site actually sends: traffic, your app metrics grouped as you grouped them, custom events and health. When AI is available it may arrange it more specifically. You can edit it any time, and your edits are never overwritten.

The script masks them in the visitor's browser, before anything is sent. Many sites serve their app for any URL, so a visitor who pastes an address into the address bar would otherwise send it as the page's path; instead /alice@example.com arrives as /:email. This is always on, and email addresses in error messages are masked too. IDs in paths, such as UUIDs, arrive as :id, you can hide short codes with the tag's data-mask attribute, and the query string is never sent.

The script sets no cookies and stores nothing in the browser, and IP addresses aren't stored. Whether you need any notice depends on the laws that apply to you, so check with your own adviser.

Page views and events are counted as received. Visitors are counted per day with a hash that changes daily, so the same person on two days counts twice, and ad blockers or disabled JavaScript hide some visits.

Members of your workspace, the AI apps you connect (read-only, and only the workspaces you pick), and anyone you share a report page link with.

Claude (web, desktop, mobile and Claude Code) and any MCP client that supports remote servers over Streamable HTTP with OAuth sign-in.

No. Mosaicdeck computes every number; the AI only reads and reports them. The server tells the AI to report numbers as given.

Each workspace has an hourly limit on tool calls: 60 on Free, 600 on Pro and 2,000 on Agency. One question often uses a few calls.

Your first workspace gets a 14-day Pro trial with no card required. After it ends, the workspace moves to Free unless you subscribe.

You're emailed at 80% and 100%. Collection continues to 120%, then page views and custom events are dropped until the month ends or you upgrade. Errors, uptime and app metrics keep working. There are no surprise charges.

On the Agency plan: 5 members are included, and you can add more seats. Members can be owners, admins or viewers.
