WListDB VS Diffyn

WListDB's answer

WListDB combines the two things gamers usually need separate tools for: HowLongToBeat-style playtime data (Main Story / Main + Extras / Completionist) and a full backlog tracker with statuses, ranked lists and reviews. Entry is automated — import your whole Steam library in one click instead of adding games one by one — and a free desktop app detects running games and tracks your play sessions automatically, split by phase and compared against community averages. At the end of the year you get a shareable recap of everything you played.

Diffyn's answer:

Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.

WListDB's answer

Less manual work: one-click Steam import instead of typing in hundreds of games, and automatic session tracking through the desktop app instead of manual timers. Deeper playtime tracking than catalog-style trackers (per-run hours split by Main / Extra / Completionist phases), and personal tracking that pure playtime databases don't offer. Core features are free with no ads, and the app is available in 5 languages.

Diffyn's answer:

Diffyn is the platform that specializes on both change management and multi-model analysis.

WListDB's answer

Next.js and React on the frontend, NestJS with PostgreSQL on the API, and an Electron desktop app for automatic play session tracking. All TypeScript.

Diffyn's answer:

React, Next.js, POSTGRESQL

WListDB's answer

Gamers with large backlogs — the "patient gamer" type with a 100+ game Steam library who wants to know what they actually finished, how long games take to beat, and what to play next. Also players who enjoy ranking and sharing their collections through public lists and year-in-review recaps.

Diffyn's answer:

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.

WListDB's answer

The founder has been a patient gamer for years. His Steam library hit 300+ games and he had no idea what he'd actually completed — spreadsheets didn't stick. So he built WListDB: connect Steam once, sync your library, mark status as you play, and get a recap at the end of the year with games finished, hours played and top genres. It's the tool he wanted for himself, kept free with no ads on the core features.

Diffyn's answer:

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.

WListDB's answer

WListDB is a free consumer app for individual gamers, not a B2B product — it has no corporate customers.
