discord.py-self
A fork of the popular discord.py for user accounts
discord.py-self is a Python API wrapper forked from discord.py and adapted for Discord user-account APIs. It provides an async-ready Python interface with familiar patterns for developers who know the original discord.py ecosystem. The library includes rate limit handling, performance-oriented implementation choices, upstream compatibility goals, and coverage for many user-specific Discord systems. It supports areas such as sessions, read states, relationships, connections, interactions, application management, and other account-level features. The project clearly warns that automating user accounts violates Discord’s Terms of Service and is not recommended. It is best viewed as a proof-of-concept or research-oriented fork rather than a safe replacement for official Discord bot libraries. -

Some advanced areas, such as threads, forums, reactions, and AI summaries, are only partially supported.

OpenCord
An open-source Material You implementation of the Discord Android app
OpenCord is an archived open-source Android client project that aimed to recreate Discord with a Material You interface. It was built in Kotlin and focused on bringing a more native Android design language to a Discord-style mobile experience. The project was still a work in progress and prioritized implementing stock client behavior before adding custom features. Its README clearly warns that the project is discontinued and that downloading the release APK may create Discord Terms of Service risk. OpenCord is best understood as a historical or experimental client implementation rather than a recommended daily-use app. It remains useful for developers studying Android, Jetpack Compose, Discord-like interfaces, and unofficial client architecture.
