Porydex is a combined Pokédex and Pokémon Showdown usage stats viewer, designed to make it easy to browse and analyze metagame trends over time.
It's also intended to be a spiritual successor to veekun.com, with all its data ripped straight from the games and fully indexed and searchable. We're not quite there yet, but we're getting close.
All the code for Porydex is available on GitHub. If you're in the tiny midsection of the [software developer/Pokémon player/stats nerd] Venn diagram, feel free to contribute.
