Learn about using Sentry with Quart.

The Quart integration adds support for the Quart Web Framework.

Install sentry-sdk from PyPI with the quart extra:

pip install --upgrade sentry-sdk[quart]

To configure the SDK, initialize it with the integration before or after your app has been initialized:

from quart import Quart

import sentry_sdk
from sentry_sdk.integrations.quart import QuartIntegration


app = Quart(__name__)

from quart import Quart

sentry_sdk.init(...)  # same as above

app = Quart(__name__)

async def hello():
    1/0  # raises an error
    return {"hello": "world"}


When you point your browser to http://localhost:5000/ a transaction in the Performance section of sentry.io will be created. Additionally, an error event will be sent to sentry.io and will be connected to the transaction.

It takes a couple of moments for the data to appear in sentry.io.

  • The Sentry Python SDK will install the Quart integration for all of your apps.

  • All exceptions leading to an Internal Server Error, from before/after serving functions, and background tasks are reported.

  • Request data is attached to all events: HTTP method, URL, headers. Sentry also excludes personally identifiable information (such as user IDs, usernames, cookies, authorization headers, IP addresses) unless you set send_default_pii to True.

  • Each request has a separate scope. Changes to the scope within a view, for example setting a tag, will only apply to events sent as part of the request being handled.

  • Logging with any logger will create breadcrumbs when the Logging integration is enabled (done by default).

  • Quart: 0.16.1+
  • Python: 3.7+
