Best for building chat and calls into your own app

OpenIM is open-source chat, voice and video infrastructure for apps, not a chat app you install and use. The open-source edition is free to host yourself and meant for development. Production-ready clients sit on Business and Enterprise plans with no published price.

Who OpenIM is for

  • Fits if you are a developer who wants chat inside your own product
  • Works for companies that will host their own messaging server

Who OpenIM is not for

  • Not for you if you want a ready chat app, as the open-source part is for building one
  • Watch out: Business and Enterprise prices are not published
  • Watch out: voice and video are separate modules bought as needed
  • Skip it if you do not want to self-host, since Kubernetes deployment is an Enterprise feature
  • Too light for production without the commercial clients, as the site says Enterprise is for that

  • CFeaturesChat, voice and video, SDKs and webhooks. Voice, video and meetings are separate paid modules.
  • DEase of useNo rating on record. It is an SDK and server that developers build on and host.

Keep OpenIM, or make your own?

Keep it

To replace OpenIM you would be making chat that a whole team counts on staying up. That is not a weekend's work, with an AI app builder or without one.

That makes this kind of software worth paying for, not this one in particular: 47 of the 75 other team communication apps grade higher. OpenIM is open source, so there is a third way: take its code and run it yourself.

What you could not

  • Chat that a whole team counts on staying up.
  • Video calls.
  • A real app for iOS and Android. Something home-made would be a web page.
  • An API that other software can build on.
  • What a company asks for before it lets staff use something: roles and permissions.

What this rests on. OpenIM’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.

What is OpenIM?

OpenIM is open-source communication infrastructure for building chat, messaging, voice calls and video meetings into an app or an existing system. It supplies a server, client SDKs, server APIs and webhooks, and you can deploy it on your own infrastructure. It is not a finished chat app on its own, though Business and Enterprise editions add production-ready client apps.

Worth knowing

  • OpenIM is not a single chat app. Open Source is meant for development and custom clients, and the site says Enterprise is for production.
  • Business and Enterprise have no published prices; they are bought through a request-a-trial and contract process.
  • Voice and video and video meetings are separate modules purchased as needed on the commercial editions.
  • The open-source GitHub page lists an Electron demo app for Windows, Mac and Linux, but the site presents these as demos.

Chat and messaging
One-to-one chat, groups, large groups, message history, offline messages, receipts, search and multi-device sync.
