Hack.Chat – Minimalist Open Source Chat App for Private Conversations

Hack.Chat is a minimalist, open source chat platform that runs directly in your browser. It is designed to be distraction-free, privacy-oriented, and incredibly lightweight. Unlike mainstream messaging apps, Hack.Chat doesn’t require any account registration, doesn’t keep message history, and does not bombard you with advertisements. It’s a chat service built purely for communication, nothing more and nothing less.

What Makes Hack.Chat Unique?

Hack.Chat stands out from other chat applications because of its extreme simplicity and focus on privacy. To join or create a channel, all you need to do is add ?channelname to the URL. For instance, entering https://hack.chat/?programming will take you directly to a chat room named programming. There is no central directory of channels, which means only people who know the exact channel name can access it. This makes Hack.Chat perfect for secret group discussions, study groups, or private collaborations.

Main Features

• 💬 Minimalist Interface: Clean design focused solely on chatting.
• 🔒 Privacy-Friendly: No data tracking, no message history, no user profiles.
• ⚡ Lightweight: Runs instantly without installation.
• 🌍 Cross-Platform: Works on browsers, Android, desktop, and more.
• 📂 Open Source: Freely available code on GitHub.

Formatting Options

Hack.Chat supports special formatting that makes it more useful for programmers, students, and communities that require code or math sharing:

• Whitespace Preservation: Spaces and tabs are preserved, useful for code snippets.
• LaTeX Support: Inline math using $...$ and block math using $$...$$.
• Syntax Highlighting: Use ```language code``` for highlighted code blocks.

LaTeX Example

ζ(2) = π^2 / 6
∫0^1 ∫0^1 1/(1-xy) dxdy = π^2 / 6

Integration with Bots and Clients

One of the strengths of Hack.Chat is its open API and compatibility with external tools. Many developers have built bots and clients that enhance its functionality:

• 🤖 Moderation bots for managing discussions
• 📱 Android apps for mobile users
• 💻 Desktop apps for Windows, Linux, and macOS
• 🧩 Browser extensions for Chrome and Firefox

You can find a large list of third-party tools on the Hack.Chat 3rd Party Software repository.

Advantages Compared to Mainstream Apps

While WhatsApp, Telegram, and Discord dominate the messaging space, Hack.Chat offers unique advantages:

• No need for phone numbers, emails, or accounts.
• Zero ads or commercialization.
• No message storage; conversations vanish once closed.

• Perfect for private and distraction-free group chats.

Limitations

Of course, Hack.Chat is not without its limitations:

• No multimedia support (no images, videos, or file sharing).
• Lacks end-to-end encryption (only uses HTTPS transport).
• No push notifications in default browser use.
• No discovery features such as public channel lists.

ws.on('open', () => { ws.send(JSON.stringify({cmd: 'join', channel: channel, nick: nick})); });

ws.on('message', (data) => { let msg = JSON.parse(data); if(msg.cmd === 'chat') { console.log(${msg.nick}: ${msg.text}); } });
