Indexers

Indexers tell Servarr where to search for media. PrepArr supports two approaches: manual indexer configuration or Prowlarr-managed sync.

Prowlarr Sync (Recommended)

When using Prowlarr to manage indexers centrally, set prowlarrSync: true in your Sonarr/Radarr config:

{
  "prowlarrSync": true
}

This tells the sidecar to skip indexer management entirely, preventing conflicts with Prowlarr’s indexer synchronization. See the Prowlarr Sync guide for the full setup.

Manual Indexer Configuration

If you’re not using Prowlarr, configure indexers directly:

Schema

{
  name: string                    // Indexer display name
  implementation: string          // Implementation type
  implementationName: string      // Human-readable name
  configContract: string          // Configuration contract
  definitionName?: string         // Cardigann definition name
  fields: ConfigField[]           // Indexer-specific settings
  enable: boolean                 // Default: true
  priority: number                // Default: 25
  appProfileId?: number           // Application profile ID
  tags: number[]                  // Tag IDs (default: [])
}

Newznab Example

{
  "indexers": [
    {
      "name": "NZBgeek",
      "implementation": "Newznab",
      "implementationName": "Newznab",
      "configContract": "NewznabSettings",
      "fields": [
        { "name": "baseUrl", "value": "https://api.nzbgeek.info" },
        { "name": "apiKey", "value": "your-api-key" },
        { "name": "categories", "value": [5000, 5040] }
      ],
      "enable": true,
      "priority": 25
    }
  ]
}

Cardigann/Torznab Example

{
  "indexers": [
    {
      "name": "My Indexer",
      "implementation": "Cardigann",
      "implementationName": "Cardigann",
      "configContract": "CardigannSettings",
      "definitionName": "myindexer",
      "fields": [
        { "name": "definitionFile", "value": "myindexer" },
        { "name": "baseUrl", "value": "https://myindexer.example.com/" }
      ],
      "enable": true,
      "priority": 25,
      "appProfileId": 1
    }
  ]
}

Important

• Do not include an indexers array when using prowlarrSync: true. The sidecar will remove manually configured indexers if they conflict with Prowlarr sync.
• If you have "indexers": [] (empty array) in your config, the sidecar will remove all existing indexers. Either omit the field entirely or set prowlarrSync: true.
