Rainbow is Alcatel-Lucent Enterprise's platform for messaging, meetings and business telephony, with APIs and a choice of public cloud, alongside an existing phone system, or private cloud. No price is published, and it is aimed at organisations rather than individuals or small teams. - **Value for money: C.** No price on the pages read, so it sits in the middle. It is sold through the vendor. - **Free plan and trial: F.** No free plan and no trial are listed anywhere on the pages read. - **Features: B.** Chat, meetings, telephony, AI services, a Teams connector and developer APIs. The pages do not say which features come with which licence. - **Ease of use: C.** No store rating on record. A platform sold to organisations means a deployment to set up. - **Platforms and integrations: A.** Web, Mac, Windows, iOS and Android apps, APIs and SDKs, and a Microsoft Teams connector.

The category's chart of price against score: https://toolgpa.com/charts/team-chat ## Keep it, or make your own? **Keep it.** To replace Rainbow 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: 37 of the 50 other team communication apps grade higher. - You could not: Chat that a whole team counts on staying up. - You could not: Video calls. - You could not: Apps for macOS, Windows, iOS and Android that stay in step with each other. - You could not: It plugs into other products, Microsoft Teams among them, and has an API. - You could not: AI features, unless you pay a model provider for each request yourself. - You could not: What a company asks for before it lets staff use something: HIPAA. - You could not: Sharing with other people, which means accounts and invitations. - You could not: The depth: we grade its features B, which means it covers the whole job.
