Cloudy

Microsoft 365 and Google — OneDrive, SharePoint, mail and calendar — in one GNOME-native window.

A native GTK4 / Libadwaita super-app for Fedora that brings Microsoft 365 (OneDrive + Teams/SharePoint, Mail, Calendar, Chat, Teams channels + OneNote) and Google (Gmail, Calendar, Drive, Chat) into one window — with file-manager (Nautilus) integration, live network-drive mounts, and a unified, provider-agnostic mail + calendar + chat surface.

Cloudy does not reinvent sync engines. It orchestrates proven backends — rclone for the FUSE file mounts, and Microsoft Graph / Google REST for mail, calendar & chat — behind one adaptive UI.

Features

• Microsoft 365 (OneDrive + Teams/SharePoint libraries) and Google (Gmail, Calendar, My Drive) accounts side by side.
• Files as live rclone FUSE mounts — two-way network drives that appear in GNOME Files and an in-app browser (not synced copies), with right-click OneDrive / SharePoint share links and optional offline sync.
• Mail: read (HTML), compose, reply/reply-all, with Me / Teams / Shared mailbox sources and contacts autocomplete.
• Calendar: month grid + agenda, event detail with an attendee response tracker, and create / edit / delete events + RSVP.
• Chat: a Teams-style messenger for Teams chats (work/school Microsoft accounts) and Google Chat (Workspace) — 1:1, group and meeting threads, inline images (attach or paste), emoji reactions, @mentions, reply/forward (with clickable reply quotes that jump to the original message), edit/delete, multi-select, group create + member management, a live list that floats new conversations to the top, presence dots, and message search.
• Teams (Microsoft work/school): pick a team to browse its channels, then read a channel's posts with threaded replies (and post / reply), or open its Notes tab — the team's OneNote notebook, with sections and pages you can read (text + inline images) and create or edit.
• Dashboard: an at-a-glance overview across every account — upcoming events, recent mail, file changes, pinned mailboxes/calendars, and an Activity feed of recent chats and the latest posts in channels you star (★ in the Chat / Teams headers).
• Desktop integration: system mailto: / .ics handler, new-mail/event notifications, and a Nautilus extension for status emblems.
• Secrets stored via libsecret — never plaintext. No telemetry; the committed repo ships zero credentials.

Install

Built and tested for Fedora 44 (GNOME 50).

# Flatpak (single-file bundle from a release):

Build from source

# 1. Install everything (toolchain + host backends + Flatpak runtime):
make bootstrap

# 2a. Build, install, and run locally:
make run

# 2b. …or build a sandboxed Flatpak:
make flatpak flatpak-run

# 2c. …or build distributable artifacts (RPM + .flatpak) into release/:
make release

Common targets: make build, make test, make lint, make clean. Dev toolchain is user-space (meson/ninja via pip --user). OAuth client IDs are baked at build time or supplied via .env — see docs/SECRETS.md.
