Start scanning

You can use Snyk to scan your code manually and automatically using the Snyk CLI, the Snyk Web UI, the Snyk API, and by running PR Checks.

Scans (tests) may be limited on your account, depending on your pricing plan. For more information, see What counts as a test?

Scan using the CLI

See Getting started with the CLI for more details.

Use the following Snyk CLI commands for specific scanning methods:

Command	Function	More details
snyk test	Scan open-source code	Use Snyk Open Source from the CLI
snyk code test	Scan application code	Use Snyk Code from the CLI
snyk container test	Scan container images	Use Snyk Container from the CLI
snyk iac test	Scan infrastructure as code (IaC) files	Snyk CLI for IaC
snyk monitor and snyk container monitor	Continually monitor a Project for new vulnerabilities.	Monitor your projects at regular intervals

Scan using the Web UI

A scan runs when you import a Snyk Project (see Import a Project to scan and identify issues or click the Retest now button on a Project. Snyk then automatically runs periodic scans on that imported Project, to see if your code is affected by newly disclosed vulnerabilities.

See Explore Snyk through the Web UI.

The default scanning frequency and available frequencies vary depending on the type of Project: for more information, see Usage settings. You can also set the frequency in the Project Settings (see View and edit Project settings) or use the API Endpont Updates project by project ID.

Scan using the API

The Snyk API offers a set of endpoints to test your code. Scans are counted when calls are made to the test endpoint.

For details, see the API Test endpoint documentation.

Using PR Checks

Snyk can scan every new Pull Request (PR) submitted on your monitored repositories to help prevent new vulnerabilities from being added to your codebase.

See Pull Request Checks for details.
