Tinode Instant Messaging Server
Instant messaging server. Backend in pure Go (license GPL 3.0), client-side binding in Java, Javascript, and Swift, as well as gRPC client support for C++, C#, Go, Java, Node, PHP, Python, Ruby, Objective-C, etc. (license Apache 2.0). Wire transport is JSON over websocket (long polling is also available) for custom bindings, or protobuf with gRPC. Persistent storage RethinkDB, MySQL and MongoDB (experimental). A third-party unsupported DynamoDB adapter also exists. Other databases can be supported by writing custom adapters.
Tinode is not XMPP/Jabber. It is not compatible with XMPP. It's meant as a replacement for XMPP. On the surface, it's a lot like open source WhatsApp or Telegram.
Version 0.16. This is beta-quality software: feature-complete but probably with a few bugs. Follow instructions to install and run or use one of the cloud services below. Read API documentation.
Why?
The promise of XMPP was to deliver federated instant messaging: anyone would be able to spin up an IM server capable of exchanging messages with any other XMPP server in the world. Unfortunately, XMPP never delivered on this promise. Instant messengers are still a bunch of incompatible walled gardens, similar to what AoL of the late 1990s was to the open Internet.
The goal of this project is to deliver on XMPP's original vision: create a modern open platform for federated instant messaging with an emphasis on mobile communication. A secondary goal is to create a decentralized IM platform that is much harder to track and block by the governments.
Installing and running

Public service
A public Tinode service is now available. You can use it just like any other instant messenger. Keep in mind that demo accounts present in sandbox are not available in the public service. You must register an account using valid email in order to use the service.
Web
TinodeWeb, a single page web app, is available at https://web.tinode.co/ (source). See screenshots below. Currently available in English, Simplified Chinese, Russian. More translations are welcome.
Android
Tinode for Android a.k.a Tindroid is stable and functional (source). See the screenshots below. A debug APK is also provided for convenience. Currently available in English, Simplified Chinese, Russian. More translations are welcome.
iOS
Tinode for iOS a.k.a. Tinodios is stable and functional (source). See the screenshots below. Currently available in English, Simplified Chinese. More translations are welcome.
Demo/Sandbox
A sandboxed demo service is available at https://sandbox.tinode.co/.
Log in as one of alice, bob, carol, dave, frank. Password is <login>123, e.g. login for alice is alice123. You can discover other users by email or phone by prefixing them with email: or tel: respectively. Emails are <login>@example.com, e.g. alice@example.com, phones are +17025550001 through +17025550009.
When you register a new account you are asked for an email address to send validation code to. For demo purposes you may use 123456 as a universal validation code. The code you get in the email is also valid.
Sandbox Notes
- The sandbox server is reset (all data wiped) every night at 3:15am Pacific time. An error message
User not found or offlinemeans the server was reset while you were connected. If you see it on the web, reload and relogin. On Android log out and re-login. If the database was changed, delete the app then reinstall. - Sandbox user
Tinois a basic chatbot which responds with a random quote to any message. - As generally accepted, when you register a new account you are asked for an email address. The server will send an email with a verification code to that address and you can use it to validate the account. To make things easier for testing, the server will also accept
123456as a verification code. Remove line"debug_response": "123456"fromtinode.confto disable this option. - The sandbox server is configured to use ACME TLS implementation with hard-coded requirement for SNI. If you are unable to connect then the most likely reason is your TLS client's missing support for SNI. Use a different client.
- The default web app loads a single minified javascript bundle and minified CSS. The un-minified version is also available at https://sandbox.tinode.co/index-dev.html
- Docker images with the same demo are available.
- You are welcome to test your client software against the sandbox, hack it, etc. No DDoS-ing though please.
