Overview

What is Checkrr?

Checkrr is an auto-hosted media library quality control tool. It scans your library (videos, audios, images) to detect corrupted files and, if you wish, automatically replaces them via Sonarr, Radarr, or Lidarr. It targets Plex installations and the *arr ecosystem.

Detection relies on several combined methods: ffprobe analysis, magic number and MIME type verification, and file hashing. A local hash database speeds up subsequent scans by only re-analyzing new or modified files. A read-only mode allows auditing without deleting anything.

Checkrr supports multiple library paths, exports its statistics to InfluxDB 1/2 for long-term tracking, and deploys easily in a Docker container.

Host Checkrr at DINAO

No managed container for Checkrr: this application is installed on a VPS hosted in France (1 vCPU / 256 Mo / 1 Go minimum).

Checkrr needs a level of access to the machine that the managed container, shared between several customers, does not give. Two VPS hosted in France: DINAO installs and manages it for you, or you administer it yourself.

Technical reason: bind mount of a host path (named volumes only in the managed offer).

About Checkrr 6 questions

What exactly is Checkrr for?

Checkrr analyzes your media library to detect corrupted files (video, audio, image) and, if necessary, automatically replaces them via Sonarr, Radarr, or Lidarr. It targets Plex installations and the *arr ecosystem.

How does it detect a corrupted file?

Through several combined methods : ffprobe analysis, magic number and MIME type verification, and file hashing. A local hash database speeds up subsequent scans by avoiding re-analysis of unchanged files.

Can it be used without deleting anything?

Yes. A read-only mode allows auditing the library and listing problematic files without triggering any deletion or replacement.

Where does the analysis of my files take place?

On the DINAO infrastructure in France, in one of the available datacenters. Your media library analysis never leaves the territory.

Can I track results over time?

Yes. Checkrr exports its statistics to InfluxDB 1 or 2, allowing you to monitor the health status of your library via dashboards.

Is this application tested before it is offered?

This application has not yet passed our automatic deployment test. It can still be installed, but we invite you to contact us before ordering: we will then test it as a priority. The deployment template used was last updated on 3 July 2026. Each new version released by the publisher triggers this test again: the date above therefore follows the version actually offered.
