About Logs in Studio Two

Logs show what your site's code does while it runs. Your code writes log entries with the Wix monitoring client, and you read them on the Logs page in the site dashboard. Use log entries to see what your backend did for a request, check values while you debug, and find errors that visitors hit.

What gets logged

Your site's logs contain:

• Entries your code writes. Your code writes log entries with the monitoring client. An entry can be a message at a severity level, such as a warning, or an error your code caught. Either kind can include extra details, such as an order ID.
• Uncaught backend errors. When backend code throws an error that it doesn't catch, Wix logs the error automatically.

Nothing else is logged. Wix doesn't capture console output, or uncaught errors in code that runs in the browser. To record a browser error, your code needs to catch it and log it. console output from code in the browser appears in the browser's developer tools. console output from backend code isn't shown anywhere.

Because Wix logs nothing else, your logs don't fill up with output you didn't mean to record.

Which code can write logs

You can write log entries with the monitoring client, not with console, from:

• Backend code, such as HTTP endpoints, event handlers, and service plugins.
• Code in site extensions that runs in the visitor's browser, such as an Editor React Component (ERC).

Code in dashboard pages can't write log entries.

Backend code writes log entries both in Preview and on the live site. Code that runs in the visitor's browser writes log entries only on the live site. Entries from Preview and from the live site appear together on the Logs page. Nothing in an entry shows whether it came from Preview or the live site.

Where to view logs

The Logs page is in the site dashboard under Developer Tools > Logs. You can also open it from the Studio Two editor. Open the Code tab, click Developer Tools on the left edge, and select Logs.

On the Logs page, you can watch entries arrive live or review earlier entries, filter by severity, search, and open an entry's full details as JSON. See View Logs in Studio Two.

How long logs are kept

Wix keeps log entries for 24 hours, and doesn't sample or limit them. To keep them longer, or to analyze them in another tool, forward them to an OpenTelemetry endpoint.

Who can view logs

A Wix user can view a site's logs if they own the site, or if their collaborator role includes access to developer tools.

Logs and related tools

The following table compares Logs with the other tools that show or send data about your site's code:

Tool	Where	What it shows
Logs	Site dashboard, Developer Tools > Logs	Entries your site's code writes while it runs, plus uncaught backend errors
Monitoring	Site dashboard, Developer Tools > Monitoring	Request counts, error rates, and response times for your backend endpoints
Signal Forwarding	Site dashboard, Developer Tools > Signal Forwarding	Endpoints that receive copies of your logs and traces. Traces record your backend requests and how long each one took.
WIX LOGS panel	Bottom of the Code tab	Messages from the development environment, such as build and sync activity. Doesn't show your site's runtime logs or console output.
