messhub — an open-source notification aggregator for Linux and Windows

⚡ The gist in 5 seconds - The messhub program intercepts system notifications and displays them on a single translucent board with columns per app. - Available for Linux (.deb and.rpm packages) and Windows 10/11 in beta. - It doesn't replace messengers: you can't reply from the board, and it only sees notifications shown by the system. ### 🔍 What was found The author DanielLetto2025 published an article on Habr on September 24 about his program messhub. It's an open-source desktop notification aggregator: it listens to the common system notification channel, writes messages to a local database, and displays them on a translucent board at the bottom of the screen. A separate column is created for each app: work messenger, Telegram, MAX, WhatsApp, email. Multiple messages from one chat are combined into a single card. The board works on Linux (Ubuntu, Debian, Mint —.deb package; Fedora, openSUSE —.rpm) and Windows 10/11 in beta. Read messages are automatically removed after a day; anything accidentally marked can be restored within five seconds. A message can be snoozed — it will return in an hour, in the evening, or tomorrow morning. Filter rules work like email ones: hide a chatty chat, pin messages from your boss, highlight mentions of your name, play a sound on the word "urgent," forward specific messages to Telegram. A "Why is this?" button explains which rule was triggered. Rules are combined into profiles: "Work" turns on on weekdays during the day, "Home" in the evening and on weekends. Statistics show who writes most often, which chats are noisy, and at what hours the most messages arrive. There's a search across the entire history, including read and hidden messages. ### 💡 Why it matters The problem of information noise is familiar to anyone who works at a computer: pop-up windows disappear after a couple of seconds, and after a call or lunch it's easy to forget about an important message. messhub solves this: all missed notifications stay on the board, sorted by app, until you mark them yourself. Filter rules, "Work" and "Home" profiles, a focus mode, and a blur button for screen sharing are practical tools for reducing anxiety and getting organized. Moreover, the program doesn't send data to the cloud, doesn't read messenger databases, and doesn't require account access. Email can be connected directly from mailboxes: Yandex, Mail.ru, Gmail, Outlook, iCloud. ### 🧩 Context The author got tired of messages from work chats, family Telegram, the building chat, email, and reminders popping up for a couple of seconds and disappearing. To not miss anything, he had to open each app in turn and scroll through conversations. messhub became the answer to this pain: it simply remembers everything the system has already shown on screen. The program doesn't reach inside messengers, so it works with all apps right away without special access. On the roadmap — short summaries of what was missed while you were away, computed locally without the cloud. The program is free and open source.
