What is it?

Flare is a social media client that combines Mastodon, Misskey, Bluesky, X, Pixiv, Fanbox, Nostr and RSS feeds into a single unified timeline. Users can follow content from several accounts and platforms without switching between apps.

Beyond reading, it supports cross-posting to multiple platforms at once, along with lists, polls, bookmarks, Misskey antennas, Bluesky feeds and DMs, and RSS subscription management. An optional built-in AI agent can use an OpenAI-compatible endpoint or on-device models for summaries, post and profile insights, and queries over local cache and history. An anonymous mode and local filtering are also included.

The app is built with Kotlin Multiplatform and runs on Android, iOS, macOS, Windows, Linux (AppImage) and in the browser through a Svelte web client.
