B4cklog is a cross-platform game library, backlog, discovery, and community application. The project is currently in Early Alpha.

The public web app is available at https://b4cklog.rarmash.ru.

• Personal game library with backlog/status tracking, favorites, completion and mastery state.
• Playthroughs, play sessions, private notes, journal timeline, and calendar history.
• Game search, discovery, platform catalogs, detailed Game Hub pages, screenshots, trailers, series, editions, companies, and related games.
• Ratings and reviews, review likes and comments, activity feeds, notifications, profiles, followers, and following.
• Public and private custom lists with notes, ordering, reordering, discovery, and profile integration.
• Connected accounts and imports, including official Steam account linking, library synchronization, pending-match resolution, exclusions, playtime tracking, and Backloggd imports.
• English and Russian interfaces with light, dark, and system themes.
• Shared product behavior across the React web client and Flutter mobile client.

• B4cklog — superproject that pins the components and owns shared development, CI, Docker Compose, and deployment configuration.
• B4cklog-Server — Kotlin / Spring Boot backend API.
• B4cklog-Web — React / TypeScript web application.
• B4cklog-Mobile — primary Flutter mobile client for Android and iOS; the previous native Android client is retained as legacy code.
• B4cklog-Docs — product, architecture, development, deployment, and feature documentation.

• Backend: Kotlin, Spring Boot, JDK 21, PostgreSQL, Flyway, Spring Security, JWT.
• Web: React, TypeScript, Vite.
• Mobile: Flutter / Dart, targeting Android and iOS.
• Game metadata: IGDB.
• Infrastructure: Docker, Docker Compose, Caddy, GitHub Actions, GHCR.

The superproject is the easiest way to work with the full stack:

git clone --recurse-submodules https://github.com/B4cklog/B4cklog.git
cd B4cklog
cp .env.example .env
docker compose -f compose.dev.yaml up --build

Component repositories also contain their own setup instructions. Project documentation lives in B4cklog-Docs.

B4cklog is being built as its own product while using established backlog applications such as Backloggd as a reference for expected workflows. Current work is focused on finishing and polishing the Early Alpha experience across web and mobile before the later Open Beta and 1.0 stages.
