I’ve been building an /*arr stack of apps to automate manga and comics. Together, they allow you (and ur users) to request media, then automate and organize it for you.
- Edit: This was made with AI! My apologies for forgetting to state that. I spent a lot of time testing and iterating these apps, but they are very much built with Claude and Codex!
Mangarr — manga library automation
Mangarr helps you keep a manga library current and tidy.
- Search for series with cover art, descriptions, and up-to-date chapter lists.
- Choose which series and chapters you want to follow, then have new chapters added to your library automatically.
- See a clear “wanted” view so you know exactly what is missing.
- Browse your collection in a poster-style library and see each series’ chapter progress at a glance.
- Works alongside an existing collection: it can recognize what you already have, so it focuses on the gaps instead of starting over.
- Scan your folders for newly added files, review anything it could not identify, and match it manually when needed.
- Preview and apply consistent filenames without overwriting or deleting your existing files.
- Keeps each chapter neatly organized and ready for a separate reader such as Komga or Kavita.
Pullarr — comics library automation
Pullarr is the western-comics counterpart to Mangarr.
- Search comics by series, with cover art, publisher details, issue lists, and release dates.
- Follow the issues you care about and have newly released issues added to your library automatically.
- See missing issues in one place instead of manually checking long-running series.
- Keep your comics in a clean, consistent folder structure, ready for Komga or Kavita.
- Bring an existing library with you: Pullarr can scan your folders, recognize files you already own, and avoid downloading them again.
- Preview renames before making any changes, find duplicate files, and clean up mismatched items.
- Manually match collected editions or trade paperbacks to the issues they contain, so your library progress stays accurate.
- Offers more detailed creator, story, and collection information when available.
NextPanel — a request app for your library
NextPanel gives other people an easy, friendly way to discover and request manga or comics from the library.
- One place to search across both manga and western comics.
- A Discover page with trending manga, seasonal picks, favorites, newly released comics, and new comic series.
- One-tap requests for titles that are not already in the library.
- A simple approval queue, so the library owner can approve or decline requests with a reason.
- Clear request progress: people can see when a title is being processed, partly available, or fully available.
- Notifications when a new request needs approval, or when a requested title becomes available.
- Separate accounts so people see their own requests while admins can manage everything.
- Installable on a phone like an app, with a layout designed to feel comfortable on mobile.
I built these because I wanted the convenience of a well-organized media library for manga and comics. Feedback, feature ideas, and bug reports are very welcome.
AI Project Disclosure [AIP]
AI was used in the development of these projects as follows:
- Design — Assisted: I drew up the designs and used AI to help turn those designs into the applications.
- Implementation — Generated: I defined features, tested the apps myself, and identified bugs, while AI produced most of the production code.
- Testing — Generated: AI generated much of the testing work. I also tested each app myself, identified issues, and guided what needed improvement.
- Review — Generated: AI handled most code review, while I provided direction based on the features and issues I found.
- Documentation — Pair: AI generated the initial documentation, and I refined it for accuracy and clarity.
- Deployment — Pair: AI drafted the Compose files and helped set up the automated image builds and Docker Hub publishing; I worked with it to configure and validate that setup.
I remain responsible for the projects’ direction, feature decisions, testing, and final validation.


I’ll check it out in the future if it looks like it’ll be maintained long term.
