What it is
Card Codex is a web-platform and database tool focused on the Pokémon Trading Card Game (TCG). It acts as a card tracker, price guide, and collection manager all in one. 

What it does / Key features

• Lets users catalog their Pokémon card collections, track what they own, and see which cards are missing (i.e. “wishlists”) 

• Provides real-time (or near current) market pricing by aggregating marketplace data, so collectors can see estimated values of cards in their collections 

• Offers a comprehensive set database, covering old and new expansions, to help users explore, compare, and track sets across the history of the Pokémon TCG 

• Publishes a blog / insights section with articles on trends, card evaluation, market dynamics, and more (e.g. comparing Japanese vs. English cards, TCG news) 

• Includes disclaimers that pricing is for informational purposes and that accuracy or future results are not guaranteed — it isn’t financial advice 

Opinion / Usefulness (short take)
Card Codex offers a strong and user-friendly toolset for Pokémon card collectors, whether they’re hobbyists, serious investors, or somewhere in between. Its combination of collection management and market insights makes it particularly useful for keeping track of collection value and spotting gaps in sets. The blog adds educational depth, making it more than just a database.
