Flare

Flare is an open-source, privacy-first social client that brings Mastodon, Misskey, Bluesky, X, Nostr, and RSS into one unified timeline. It supports cross-posting, lists, feeds, DMs, RSS management, and AI-powered features such as translation and summaries. Built with Kotlin Multiplatform, Flare shares its core logic across Android, iOS, macOS, Windows, and Linux, turning fragmented social feeds into a personal information hub.

Features

• Unified social inbox: Flare brings Mastodon, Misskey, Bluesky, X, and RSS together in one place, so users can follow fragmented communities through a single timeline.
• Mixed timeline experience: It merges content from multiple accounts and platforms into a coherent feed, reducing context switching between apps.
• Cross-platform by design: Built with Kotlin Multiplatform, Flare shares core logic across Android, iOS, macOS, Windows, and Linux.
• Rich platform support: Beyond basic timelines, it supports features such as polls, lists, bookmarks/favorites, Misskey antennas, Bluesky feeds and DMs, and RSS management.
• Cross-posting workflow: Users can publish to multiple platforms at once, making it practical for creators and heavy social media users.
• AI-assisted reading: Flare includes AI-powered capabilities such as translation and summaries to help users catch up on content faster.
• Privacy-first approach: As a FOSS client, it emphasizes user control with features like anonymous mode, local filtering, local history, and transparent data handling.
