    Several third-party tools include Semgrep extensions.

    Official IDE extensions

    Community-contributed IDE extensions

    The LSP Command

    All of our official extensions use the Language Server Protocol to communicate with Semgrep. This allows us to focus on one codebase that can be shared across most modern editor platforms. To implement a custom extension, one can wrap semgrep lsp to start the Semgrep Language Server, which will communicate over stdio. Alternatively, this protocol is a great way to integrate Semgrep into a project, as it can perform incremental scans, and caches various computations to hugely increase performance. Please let us know on our community Slack linked below if you do, we'd be more than happy to help in anyway.


    The pre-commit framework can run semgrep at commit-time. Install pre-commit and add the following to .pre-commit-config.yaml

    - repo:
    rev: 'v1.73.0'
    - id: semgrep
    # See to select a ruleset and copy its URL
    args: ['--config', '<SEMGREP_RULESET_URL>', '--error', '--skip-unknown-extensions']

    The pre-commit can also run custom rules and rulesets from Semgrep Code, similar to running semgrep ci using the following configuration:

    - repo:
    rev: 'v1.73.0'
    - id: semgrep-ci

    Run with Semgrep Pro rules

    If you would like to run the pre-commit hook locally while using Semgrep Pro rules:

    1. Log in to your Semgrep account. Running this command launches a browser window, but you can also use the link that's returned in the CLI to proceed:
    semgrep login
    1. In the Semgrep CLI login, click Activate to proceed.

    Version management

    Semgrep as an engine

    Many other tools have functionality powered by Semgrep. Add yours with a pull request!
