Open-source Java projects categorized as instant-messaging

Top 4 Java instant-messaging Projects

  • Conversations

    Conversations is an open source XMPP/Jabber client for Android

    Project mention: Android Jabber App | /r/jabber | 2023-05-04

    AFAIK Conversations is one of the best, if not the best. On F-Droid it’s gratis, on Google Play it costs something.

  • jitsi

    Jitsi is an audio/video and chat communicator that supports protocols such as SIP, XMPP/Jabber, IRC and many other useful features.

    Project mention: SIP/VoIP softphone with GUI that works well with most commercial SIP/VoIP services? | /r/debian | 2023-04-08

    Yep, best client I found. It is still being updated, but no official releases, you just get latest from the git tags section:

  • Mergify

    Updating dependencies is time-consuming.. Solutions like Dependabot or Renovate update but don't merge dependencies. You need to do it manually while it could be fully automated! Add a Merge Queue to your workflow and stop caring about PR management & merging. Try Mergify for free.

  • jaxmpp

    Java XMPP client library

  • tox_push_msg_app

    Tox Push Message App

    Project mention: Peer-to-Peer Encrypted Messaging | | 2022-11-20

    It's not hard for IRC-style chats, but it gets harder if you want to handle:

    * Asynchronous messaging: what if the two devices are not online at the same time, or on disjointed networks? Store the message on a server somewhere? Secure Scuttlebutt[1] relies on devices pulling encrypted data that does not belong to them.

    * NAT or firewall hole-punching, though it can be remediated by leveraging other nodes. Some implementations use a DHT[2], but you're often relying on other servers of some sort.

    * What you call contact discovery is also typically handled through a DHT of some kind. Yggdrasil-like (or hyperboria, cjdns, .onion) overlay networks are usually able to route to a public key, regardless of how it moves around on the network.

    * Push notifications. Either you accept the use of an external server (like the Tox client TRIfA, which has an add-on[3])
