Interactive Fiction Database vs The Visual Novel Database

Interactive Fiction Database (IFDB) is a free community catalog that helps players find interactive fiction games and decide what to play. Members can add and edit listings, search by title, author, or description, and narrow results with filters for genre, language, authoring system, format, rating, and publication date. Discovery tools include personalized recommendations, lists, polls, reviews, ratings, competitions, and member profiles. For supported titles, a Play Online option opens a game in a browser without an interpreter download; IFDB catalogs game information rather than hosting the games. Developers can use HTTP APIs that return JSON to search, retrieve listings, edit tags, or publish iFiction XML. Those APIs are intended for low-volume, user-driven applications, not frequent crawling or high-load mirroring. Full SQL exports excluding personal information are available through the IF Archive and updated roughly quarterly. IFDB also has web access and supports Z-machine, TADS, Hugo, and executable applications. It is maintained by the Interactive Fiction Technology Foundation and funded by supporter donations.

The Visual Novel Database (VNDB) is a free resource for information about visual novels and eroge, available on the web and through an API. Its wiki lets people add and contribute information, including general details and practical coverage of releases, localisations and producers. Registered users can vote on visual novels and maintain lists of games they want to play or have finished. VNDB also aims to introduce visual novels to a broader audience across geographic and cultural differences. The Kana HTTPS API can query the database and manage user lists. Non-commercial API access costs nothing and is subject to limits: 200 requests per 5 minutes, one second of execution time per minute, and automatic abortion of requests exceeding three seconds. API availability is best-effort, with no guarantees about stability or applicability. It does not provide some site functions, including forums, database editing and account creation. Users can obtain API tokens from the Applications tab in My Profile, and a sandbox endpoint at beta.vndb.org/api/kana is available for testing and development. VNDB's first version went live in September 2007.
