In 2026, four approaches will dominate comics collection management: Excel (free but limited), CLZ Comics (complete but expensive), CovrPrice (valuation-focused), and My Comics Collection (GCD catalog, French interface, CGC monitoring and valuation). The best choice depends on the size of your collection and your priorities.
The best applications for managing your comic collection in 2026
When you start accumulating hundreds of comics, the question always ends up being: which application should you use to manage all of that? The market today offers several serious options, each with its strengths and limitations. This honest comparison reviews the main solutions available in 2026 to help you choose the one that suits your way of collecting.
The criteria that really matter
Before comparing the applications, let's define what a comic collector really expects from a management tool. After years of feedback from collectors, five criteria come up systematically.
The database.The app must know the comics. If you have to enter everything manually (title, number, date, creators), you might as well stick to Excel. A good app has an exhaustive catalog where you just have to search and check.
Valuation.Knowing the rating of each issue and the total value of your collection has become a fundamental need, whether you collect for pleasure or for investment.
Tracking missing items.Being able to automatically identify holes in a run is what differentiates a collector tool from a simple spreadsheet.
Mobility.Viewing your collection from your phone at a convention or in store is not a luxury — that's what stops you from buying duplicates.
The interface and language.A tool that you don't use because it is poorly designed or only in English is of no use, even if it is technically efficient.
Excel / Google Sheets: the starting point
The advantages
Excel is free (or almost), you already know it, and it is completely customizable. You create your columns as you want: series, number, condition, purchase price, estimated rating, location in your longboxes. For a small collection of 50 to 200 comics,This is a perfectly viable solution..
Google Sheets adds the benefit of sharing and mobile access. You can view your spreadsheet from your phone, although the small-screen experience is far from pleasant.
The limits
No integrated database: each comic is entered by hand. No covers, no automatic valuation, no detection of missing items. Beyond 500 numbers, file maintenance becomes a job in itself. And entry errors (typos, incorrectly referenced numbers) accumulate without you seeing them.
Verdict: perfect for beginners, insufficient for a serious collection.
CLZ Comics: The Veteran
The advantages
CLZ Comics (from Collectorz.com) is one of the oldest apps on the market. Its Core database is vast and covers the vast majority of American series. The mobile interface is functional, barcode scanning is integrated, and the application allows you to manage very large collections.
The limits
The pricing model is one of the highest on the market: substantial annual subscription for full access.The interface is dated and mostly in English, which may put off French-speaking collectors. The valuation is available but is based on the partnership with CovrPrice (additional subscription). The catalog, although extensive, is proprietary and sometimes incomplete on non-American editions.
Verdict: a proven solution for English speakers with a comfortable budget, but expensive and not well suited to the French-speaking market.
CovrPrice: focused on value
The advantages
CovrPrice has positioned itself in a specific niche: the promotion of comics. The tool aggregates actual sales prices (primarily eBay) to provide fairly reliable value estimates. If your top priority is knowing the price of every issue in your collection, CovrPrice is serious about this.
The limits
CovrPrice is above all a valuation tool, not a complete collection management tool.Tracking missing items, cataloging by series, and day-to-day management experience are secondary.The interface is exclusively in English. The economic model is based on a fairly high subscription. And the coverage of non-American editions is almost non-existent.
Verdict: excellent complement for valorization, but insufficient as a main collection management tool.
My Comics Collection: the GCD catalog in French
The advantages
My Comics Collection was designed based on the real needs of French-speaking collectors. The application integrates theGrand Comics Database (GCD), the largest comics database in the world, with more than 2 million issues referenced. This means that the catalog covers not only American series, but also French (Héritage, Panini, Semic, Lug) and international editions.
Tracking is done number by issue: for each comic, you can record the condition, the CGC/CBCS grade, the purchase price, and consult the estimated valuation. Missing detection is automatic — the app displays holes in your runs without you having to search.
The interface isentirely in French(as well as in English, German and Dutch), which is a major advantage for collectors who are not comfortable with Anglo-Saxon tools. Collection sharing is integrated: a link is enough to show your collection to a friend or a potential buyer.
The limits
My Comics Collection is a relatively young app compared to CLZ. Barcode scanning is not yet integrated (cataloging is done via search in the GCD catalog). The valuation base is in continuous development and may be less exhaustive than CovrPrice on certain very specific numbers in the American market.
Verdict: the best option for French-speaking collectors who want a complete tool (catalogue, missing items, valuation, CGC) with a modern interface and an affordable price.
Tableau comparatif synthétique
Here is a summary of the key differences between the four solutions:
Base de données : Excel n'en a pas. CLZ utilise sa base propriétaire Core. CovrPrice a sa propre base centrée valorisation. My Comics Collection utilise le GCD (2M+ de numéros).
Valorisation : Excel requiert une saisie manuelle. CLZ nécessite l'addon CovrPrice. CovrPrice excelle sur ce point. My Comics Collection intègre la valorisation nativement.
Tracking missing items:non-existent on Excel, available on CLZ and My Comics Collection, limited on CovrPrice.
Interface française :Excel is in French. CLZ and CovrPrice are in English only. My Comics Collection offers a complete interface in French.
Prix :Excel is free. CLZ costs around $25-30/year. CovrPrice around $60/year. My Comics Collection offers a 14-day free trial with accessible plans.
Suivi CGC/CBCS :absent on Excel and CovrPrice, basic on CLZ, detailed on My Comics Collection (grade, certification, slab photos).
Comment choisir : la grille de décision
Le meilleur outil dépend de votre profil de collectionneur.
You start with less than 100 comics: Excel or Google Sheets is enough. But create your file correctly from the start (one line per number, clean columns) to facilitate future import into a dedicated app.
You have 200 to 500 comics and you buy regularly: it's time to upgrade to an app. My Comics Collection or CLZ will save you considerable time and avoid duplication at conventions.
You have 500+ comics and you want to know the value of your collection: an app with integrated valuation is essential. My Comics Collection combines the GCD catalog and promotion in the same tool.
You collect primarily for investment: CovrPrice in addition to your main management tool will give you the most detailed market data.
You are French-speaking and tools in English put you off: My Comics Collection is currently the only complete application with a native interface in French.
Questions fréquentes
Technically yes, but it is not recommended. Maintaining two inventories in parallel creates inconsistencies (a comic added in one app but not the other). Choose a main tool for your catalog and possibly use a complementary tool only for promotion if your main app does not offer it.
Serious applications (CLZ, My Comics Collection) store your data on secure servers with regular backups. This is also an advantage compared to Excel: if your hard drive fails, you lose your Excel file, but not your collection in a cloud app. Check that the application offers an export function (CSV or other) to keep a local copy of your data.
The Grand Comics Database, used by My Comics Collection, is the most exhaustive database for French-speaking editions (Héritage, Panini, Semic, Lug, Arédit). CLZ also covers certain international editions via its Core database, but in a less systematic manner. CovrPrice and most other tools focus almost exclusively on the US market.
Prices vary considerably. Excel is free. CLZ Comics costs around $25-30 per year for mobile + desktop access. CovrPrice is around $60 per year for full access to valuation data. My Comics Collection offers a 14-day free trial and then accessible subscription plans. Most collectors consider the cost of an annual subscription to be far outweighed by avoided duplication and better buying/selling decisions.
Yes, provided that your current application allows export (CSV, XML). Most serious tools offer this functionality. Importing into the new application may require some formatting adjustments, but is generally a manageable process. My Comics Collection offers an import wizard to make the transition from Excel or other applications easier.
