Rocket.Chat vs Stream: at a glance
What is Rocket.Chat?
Rocket.Chat 9.0 reaches rc.8 with a migration fix as candidates shrink to single patches.
The 9.0 candidate line opened on 27 October with a licensing change: LDAP, SAML and Custom OAuth now require a premium plan. Since rc.4 the candidates have been fixes, and rc.8 on 7 November carries a single one: servers that started during another server's database migration no longer keep stale settings until restart. On 6 November 8.9.1 LTS backported the 9.0 load fixes plus a security hotfix.
What is Stream?
Stream ships open-source Vision AI SDK for multi-modal app testing
Stream offers two core infrastructure APIs: real-time chat/messaging for in-app communication, and a new open-source Vision AI SDK for building and testing multi-modal AI applications. The Vision AI SDK supports live-edit-test workflows across modalities, targeting engineering teams iterating on AI features rather than end-user consumers.

6.3COMMS
Rocket.Chat 9.0 reaches rc.8 with a migration fix as candidates shrink to single patches.
◆ Current state
The 9.0 candidate line opened on 27 October with a licensing change: LDAP, SAML and Custom OAuth now require a premium plan. Since rc.4 the candidates have been fixes, and rc.8 on 7 November carries a single one: servers that started during another server's database migration no longer keep stale settings until restart. On 6 November 8.9.1 LTS backported the 9.0 load fixes plus a security hotfix.
◆ Where it's heading
9.0 is in stabilization: each candidate is smaller than the last, and the load fixes are being carried to the LTS line rather than held for the major. Native LiveKit video is being promoted step by step, from alpha to beta and now as the named default provider option.
◆ Prediction
With rc.7 down to a handful of fixes, 9.0.0 GA is the next likely release, followed by further 8.9.x LTS patches carrying the same fixes.
Stream

Stream ships open-source Vision AI SDK for multi-modal app testing
◆ Current state
Stream offers two core infrastructure APIs: real-time chat/messaging for in-app communication, and a new open-source Vision AI SDK for building and testing multi-modal AI applications. The Vision AI SDK supports live-edit-test workflows across modalities, targeting engineering teams iterating on AI features rather than end-user consumers.
◆ Where it's heading
Stream is extending beyond its established chat messaging infrastructure into AI-native developer tooling. The Vision AI SDK positions Stream as a building block for AI application developers, not just communication product teams. If this pattern continues, expect more AI-specific primitives shipped alongside the core messaging APIs.
◆ Prediction
The next move is likely deeper integration between the Vision AI SDK and Stream's existing messaging infrastructure, enabling AI apps that combine real-time communication with multi-modal inputs in a single SDK surface.
