NewtArr's Lidarr support differentiates it from Cleanuparr's Seeker

This review examines NewtArr, a Huntarr fork, focusing on its media management capabilities, particularly Lidarr integration, and contrasts it with Cleanuparr's Seeker functionality.

TL;DR

Best for: Users managing music libraries with Lidarr who need a dedicated tool for searching missing media and upgrades. Skip if: Your media stack does not include Lidarr, or if you prioritize a single-tool solution like Cleanuparr for all media types. Bottom line: NewtArr offers a specific advantage for Lidarr users, while Cleanuparr's Seeker provides similar core functionality for other "Arr" applications.

METHODOLOGY

This v0 review draws on a user's published claims and questions on Reddit, specifically a post by DissonantGuile on r/selfhosted from May 19, 2026. The review covers the stated functional difference between NewtArr (a Huntarr fork) and Cleanuparr's "Seeker functionality," primarily focusing on Lidarr support. We examine the implications of this claimed difference for media management workflows. What is not covered includes independent performance benchmarks, long-term workflow integration, resource consumption, or a comprehensive feature comparison beyond the "Seeker" aspect. We also do not cover the full feature sets of either tool, nor their respective development roadmaps or community support. Update cadence: This review will be re-evaluated if more detailed information, official documentation, or independent benchmarks become available, or if user claims diverge from observed behavior.

WHAT IT DOES

NewtArr: Lidarr integration for music

NewtArr is presented as a fork of Huntarr, a tool designed for managing media libraries within the "Arr" ecosystem (Radarr for movies, Sonarr for TV shows, Lidarr for music). Its primary function, as described by the Reddit user, is "Seeker functionality" for "searching missing media & upgrades." This implies a capability to identify gaps in a user's media collection and locate higher-quality versions of existing media, then potentially initiate downloads or updates through the respective "Arr" application. The key differentiator highlighted is NewtArr's explicit support for Lidarr, extending its search and upgrade capabilities to music libraries. This positions NewtArr as a specialized solution for users who want to apply the "Seeker" paradigm to their music collections, mirroring the functionality available for video content.

Cleanuparr: General media seeker

Cleanuparr is another tool in the self-hosted media management space, also offering "Seeker functionality." The Reddit post suggests that Cleanuparr provides similar core capabilities for searching missing media and upgrades. However, it explicitly states that Cleanuparr "does not" allow for Lidarr integration. This implies Cleanuparr's Seeker functionality is geared towards other "Arr" applications, likely Radarr and Sonarr, but lacks the specific hooks or architecture to manage music libraries effectively. For users whose primary need is to manage movies and TV shows, Cleanuparr's Seeker might offer comparable performance and features to NewtArr's non-Lidarr capabilities.

WHAT'S INTERESTING / WHAT'S NOT

What's interesting about NewtArr is its specific focus on filling a perceived gap in the "Arr" ecosystem. The existence of a Huntarr fork that explicitly adds Lidarr support suggests a demand for comprehensive "Seeker" functionality across all media types, including music. This specialization indicates a developer or community response to a specific user need, rather than a broad, undifferentiated tool. The "fork" aspect itself is interesting; it implies either a divergence in development philosophy from the original Huntarr or an attempt to revive or extend a project that might have stalled or lacked specific features. For users heavily invested in Lidarr, NewtArr represents a targeted solution that Cleanuparr, as described, does not offer.

What's not interesting, or rather, what is unclear from the available information, is the depth of "Seeker functionality" beyond the high-level description. Without specific feature lists, performance claims, or user interface details, it is difficult to assess the quality or robustness of the search and upgrade mechanisms in either NewtArr or Cleanuparr. The Reddit post suggests that, outside of Lidarr support, the functionality "seem[s] to have the same functionality." This lack of differentiation in core search logic, if true, means the choice between the two tools hinges almost entirely on the presence or absence of Lidarr in a user's stack. Furthermore, the absence of publicly available, detailed documentation or a clear project homepage for NewtArr makes a deeper technical assessment challenging.

PRICING

Both NewtArr and Cleanuparr are self-hosted tools, typically implying an open-source model with no direct monetary cost for the software itself. The source signal does not mention any pricing tiers, subscription models, or commercial versions for either tool. Users should expect to incur costs related to hardware, network bandwidth, and electricity for running these applications on their own servers or cloud instances. This pricing snapshot is based on information available as of May 19, 2026.

VERDICT

NewtArr is the clear choice for users who actively manage a music library using Lidarr and require a dedicated "Seeker functionality" to identify missing tracks or upgrade existing ones. Its origin as a Huntarr fork with explicit Lidarr support addresses a specific need within the comprehensive "Arr" media management stack. Conversely, if your self-hosted media setup does not include Lidarr, or if your primary focus is on movies (Radarr) and TV shows (Sonarr), Cleanuparr's Seeker functionality appears to offer a comparable experience based on the available information. The decision depends directly on whether Lidarr integration is a requirement for your media management workflow.

WHAT WE'D TEST NEXT

Our next steps would involve a direct, side-by-side benchmark of NewtArr and Cleanuparr's "Seeker functionality." We would establish a standardized test library for both movies/TV shows and music, varying in size and complexity. Specific tests would include: search speed for missing items across different library sizes, accuracy of upgrade suggestions (e.g., identifying true quality improvements), resource utilization (CPU, RAM, network) during scan operations, and the robustness of integration with their respective "Arr" applications. We would also investigate the ease of setup, configuration options, and the maturity of their respective communities and documentation. Finally, we would explore the underlying search algorithms and data sources each tool uses to determine if there are fundamental differences in how they identify media.
