What is SnapOtter?​

SnapOtter is an open-source, self-hosted file-processing platform for images, video, audio, PDFs, and documents. It provides a web interface, REST API, and pipelines for tasks such as conversion, compression, optical character recognition, transcription, and local AI processing.

This documentation lists only the settings that you need to change from their default values. Be aware that any changes other than those explicitly mentioned in this guide could cause issues accessing your application.

authentik configuration​

Redirect URI changes in authentik 2026.5

In authentik versions earlier than 2026.5, all Redirect URIs are automatically treated as Authorization type. If you are using one of these older authentik versions, add only the Authorization URL to your Redirect URIs and do not configure a Post Logout URI.

To support the integration of SnapOtter with authentik, you need to create an application/provider pair in authentik.

Create an application and provider​

  1. Log in to authentik as an administrator and open the authentik Admin interface.

  2. Navigate to Applications > Applications and click New Application to create an application and provider pair. (Alternatively you can first create a provider separately, then create the application and connect it with the provider.)

    • Application: provide a descriptive name, an optional group for the type of application, the policy engine mode, and optional UI settings. Note the application Slug because it will be required later.
    • Choose a Provider type: select OAuth2/OpenID Connect as the provider type.
    • Configure the Provider: provide a name (or accept the auto-provided name), the authorization flow to use for this provider, and the following required configurations.
      • Note the Client ID and Client Secret values because they will be required later.
      • Add a Redirect URI of type Strict Authorization as https://snapotter.company/api/auth/oidc/callback.
      • Select any available signing key.
    • Configure Bindings (optional): you can create a binding (policy, group, or user) to manage the listing and access to applications on a user's Application Dashboard page.

  3. Click Submit to save the new application and provider.

SnapOtter configuration​

Add the following required variables to the environment file for your SnapOtter installation:

.env
EXTERNAL_URL=https://snapotter.company
OIDC_ENABLED=true
OIDC_ISSUER_URL=https://authentik.company/application/o/<application_slug>/
OIDC_CLIENT_ID=<Client ID from authentik>
OIDC_CLIENT_SECRET=<Client Secret from authentik>

Keep the trailing slash in OIDC_ISSUER_URL, then restart SnapOtter to apply the configuration.

Configuration verification​

To confirm that authentik is properly configured with SnapOtter, log out of SnapOtter and open the integration. Click Sign in with SSO and complete the authentik flow. SnapOtter creates a local user account during the first OIDC login.
