conversations.im

One-line intro

conversations.im is an open-source XMPP instant messaging client developed by a German team. It focuses on end-to-end encryption and privacy protection, making it suitable for users with high security requirements for communications. Its core value lies in being based on an open protocol and not depending on any commercial company’s servers: users can self-host or connect to any XMPP server. In Chinese-speaking communities, it is often compared with privacy-focused messaging tools such as Telegram and Signal, but because it relies on the XMPP ecosystem, users in mainland China generally need a proxy for stable access.

Business overview

conversations.im is essentially an open-source XMPP client, not a hosted service. It is primarily maintained by German developer Daniel Gultsch, with the project hosted on GitHub and a moderately active community. The client supports end-to-end encryption protocols such as OMEMO and OpenPGP, and is compatible with standard XMPP servers such as ejabberd and Prosody. It is positioned as an alternative to commercial messaging apps like WhatsApp, especially for geeks, open-source enthusiasts, and small teams that care about data sovereignty. In terms of market position, it is one of the best-known XMPP clients on Android, but it lacks native support on iOS and desktop. Its user base is mainly individual developers, privacy advocates, and organizations that need self-hosted communications systems rather than mainstream consumers.

Who it’s for

Conversations.im has a very clear target user profile. First, it is for technically proficient individual users, especially those who already have or are willing to set up an XMPP server. Second, it suits small teams or companies that need encrypted internal communications but do not want to rely on third-party platforms. Third, it is a fit for users with very strong privacy awareness, such as journalists, lawyers, or rights advocates. It is not suitable for ordinary users who expect messaging apps to “just work,” users who need interoperability with WeChat or WhatsApp, or users in China who cannot accept additional proxy configuration. For developers, it is also a good learning tool for understanding the XMPP protocol.

Key features and highlights

• End-to-end encryption: Supports the OMEMO protocol by default, while also being compatible with OpenPGP and OTR, ensuring message content cannot be read by third parties, including server administrators.
• Open source and auditable: The code is fully public and can be reviewed by any security researcher, with no backdoors or data collection behavior.
• Decentralized architecture: It does not depend on a single service provider. Users can choose or self-host an XMPP server, keeping full control over data sovereignty.
• Multi-device sync: Supports simultaneous login from multiple clients via the XMPP protocol, with message history syncing across devices if the server supports it.
• File transfer and voice messages: Supports sending images, files, and voice messages, though file size limits depend on server configuration.
• Use without registration: Supports anonymous login through certain public servers, though this may come at the cost of feature stability.

Pricing analysis

Conversations.im itself is free and open-source software, with no purchase required. However, if users want to connect to a public XMPP server, such as the server officially provided by conversations.im, they may need to bear server operating costs, typically starting from around 5-20 USD per month. For users who self-host, the main costs are VPS rental, about 5-10 USD/month, and domain fees. Compared with fully free services such as Signal and Telegram, Conversations.im has higher hidden costs because it requires technical maintenance and ongoing effort. There is no free trial period, but users can use a self-hosted server indefinitely. There are no hidden fees, though some public XMPP servers may restrict registration or certain features.

How users in China can use it

Using conversations.im directly in mainland China comes with network obstacles. Ports commonly used by XMPP, such as 5222 and 5269, are often blocked, and most public XMPP servers are located overseas. As a result, a proxy such as a VPN or Shadowsocks is usually required for a stable connection. As for payment, the software itself is free, so no payment is needed. But if you buy a VPS to self-host a server, you will generally need PayPal or cryptocurrency, as domestic Alipay/WeChat Pay cannot directly pay most overseas server providers. Refund policy is unclear because the software itself has no fee. Domestic alternatives include WeCom/WeChat Work, which requires trusting Tencent, BIGO’s private chat features, or a self-hosted Matrix server such as Element. Overall, the barrier to entry is high for ordinary Chinese users, and it is better suited to technical users.

Pros and cons

Pros:

• ✅ Fully open source, auditable code, top-tier privacy protection
• ✅ End-to-end encryption enabled by default, with no manual setup required
• ✅ Decentralized and not dependent on any commercial company
• ✅ Supports self-hosted servers, giving users full control over their data
• ✅ Compatible with the standard XMPP protocol and interoperable with various clients

Cons:

• ❌ Requires a proxy in mainland China, creating a high network barrier
• ❌ The user interface is somewhat technical and not intuitive enough
• ❌ End-to-end encryption in group chats is not well supported, as OMEMO can be unstable in groups
• ❌ No official desktop client; users must rely on third-party apps
• ❌ No dedicated customer support; issues must be solved through the community or independently

Comparison with similar products

• Signal: Also an end-to-end encrypted messaging app, but Signal is a centralized service that relies on Signal Foundation servers and does not require self-hosting. It also requires a proxy in mainland China, but has a more user-friendly interface and supports encrypted group chats. Conversations.im’s advantage is decentralization.
• Telegram: Offers encrypted “Secret Chats,” but regular chats are not end-to-end encrypted by default, and all data is stored on Telegram’s servers. It can be accessed directly in mainland China in some cases, though certain features may be limited, but its privacy policy is less transparent than Conversations.im’s.
• Matrix/Element: Similar in decentralization, but the Matrix protocol is more modern, supports clients across all major platforms, and also requires a proxy in mainland China. Conversations.im’s advantages are being lighter-weight and more focused on the XMPP ecosystem.

Final recommendation

Conversations.im is best suited for scenarios where you are already familiar with the XMPP protocol, are willing to spend time setting up your own server, and have extremely high requirements for communication privacy, such as in sensitive industries. It is not suitable for ordinary users, people who need interoperability with WeChat or WhatsApp, or users in China who cannot accept proxy configuration. A good first step is to try its basic features for free through a public XMPP server, such as the free server provided by conversations.im, and then decide whether to self-host after confirming that your network connection is stable. Note that the software has no refund policy, but because it is open source, you can stop using it at any time.
