Stream review

Stream provides APIs and SDKs for adding chat, video, activity feeds and content moderation to apps. Its site describes customizable UI SDKs, moderation tools and agent skills for coding agents building with Stream. This is developer infrastructure, not a finished chat or video app: teams use Stream’s components to build those experiences into their own products.

The product covers several distinct jobs. Chat SDKs support customizable messaging; video SDKs cover calling and livestreaming; and activity-feed SDKs let teams add customizable feeds. The moderation workspace includes review queues, a no-code Rule Builder, enforcement actions and audit logs. Stream also describes detection for text, audio, images and video in more than 50 languages. Pricing needs a closer read before switching: the published Build, Start and Elevate limits are specifically framed around Chat, so they do not establish what video, feeds or moderation would cost.

The main appeal is breadth. A team evaluating in-app messaging can also find SDKs for video and feeds, plus moderation tools, under one provider. That can reduce the number of separate integrations a product team has to assess, though the published pricing details do not show whether all of those products are included in one plan.

The moderation feature set is more concrete than a generic claim of “AI moderation”: Stream describes review queues, a no-code Rule Builder, enforcement actions and audit logs. Its detection covers text, audio, images and video in 50+ languages, according to the product details. Agent skills and documentation are another practical addition for teams building with coding agents.

There is also a free Chat entry point. The pricing page lists Build at $0 per month, with 1,000 monthly active users (MAU), 100 concurrent connections, up to 1 million API calls and community support. For a maker building with Chat, that gives a defined starting allowance before paying. Just treat it as a Chat plan, not evidence that every Stream product is free.

The free tier has clear ceilings: Build includes 1,000 MAU, 100 concurrent connections and up to 1 million API calls. The paid Chat plans raise those caps, but Start lists $499 monthly or $399 per month billed annually, with 10,000 MAU, 500 concurrent connections, up to 5 million stored messages, 500,000 channels and 2 million API calls per month. Elevate lists $675 monthly or $599 billed annually; it keeps the same MAU and connection limits while raising the caps to 10 million stored messages, 1 million channels and 10 million API calls.

Overages can add to the bill: the pricing page lists $0.09 per extra MAU, $0.99 per extra concurrent connection, and $7 per 1 million API calls. It also lists separate charges for storage, bandwidth, images and translation. Enterprise pricing is custom, and AI moderation and Datadog integration are Enterprise add-ons with prices not published. The published pricing does not clarify costs for video or feeds, so get those figures before comparing a full-stack switch.

Stream’s listed Chat plans run from free Build to custom-priced Enterprise. Build includes 1,000 MAU, 100 concurrent connections and up to 1M API calls. Start costs $499/month, or $399/month billed annually; Elevate is $675 monthly or $599/month billed annually. Both paid plans list 10,000 MAU and 500 concurrent connections, so Elevate’s higher price buys more usage: 10M stored messages, 1M channels and 10M API calls, versus Start’s 5M messages, 500K channels and 2M calls. That is a $176 monthly or $200 annual-billing price jump.

Watch the overages: the pricing page lists $0.09 per extra MAU, $0.99 per extra concurrent connection, $7 per 1M extra API calls and separate charges for storage, bandwidth and other usage. Annual prices require annual billing. Enterprise pricing is not published, and AI moderation and Datadog add-on prices are also not published. These listed plans are for Chat; the source does not give comparable prices for video or feeds.

Treat a move to Stream as app integration work, not just a vendor-account change. Stream provides APIs and SDKs for chat, video, feeds and moderation, so the effort will depend on which features your app uses and how much of its experience is built around them. Replacing those integrations when leaving will also take engineering work. That is a practical implication of the product setup, not a published migration estimate.

The published materials do not publish data-export or import details, so confirm what you can export—including messages, channel data and moderation records—before committing. The pricing page’s MAU, connection and API limits, plus usage overages, are worth checking against your expected traffic. We were not given Reddit posts or comments for this review, so we can’t reliably say what users on Reddit report as reasons for leaving Stream. Ask Stream about export formats, migration support and any costs that apply to your data and usage before switching.
