In this tutorial, we'll walk through the steps involved in creating your first application on Stream. We'll create a new account, choose how you want to build, and get you to your first working integration.

Live video removes the one thing every other moderation system relies on - time to think before content ships. This article covers the architecture for real-time moderation - a fast, shallow path that beats your delivery window, and a slower, deeper path that corrects the call after the fact.

TLDR; Wide-column stores like Cassandra handle messages while Redis holds read state, because each subsystem's access patterns differ significantly. Presence alone generates a write on every connect, disconnect, and heartbeat, making it orders of magnitude more write-heavy than messages. End-to-end encryption prevents the server from searching, moderating, or generating push notification previews, which transport-plus-at-rest encryption

Most teams still think about bot detection as a security problem. CAPTCHAs, rate limiting, DDoS mitigation, browser fingerprinting, that's the domain of the security team, or the network layer above it. It's the gate traffic hits before it ever reaches the product. But the bots causing the most damage in 2026 aren't trying to take

Community Sift has been one of the most purpose-built content moderation platforms for gaming and online communities. If you're evaluating whether it's still the right fit, or your trust and safety team is looking at what else is out there, this guide gives you an honest comparison of the strongest moderation alternatives available today. We'll

We recently open-sourced the Stream Video ESP32 SDK, an SDK that lets an ESP32-S3 or ESP32-P4 join a Stream Video call, capture camera and microphone input, encode H.264 + Opus in real-time, and publish it over WebRTC. Someone on a browser or mobile device can then see and hear the ESP32 live. If you're

Everyone talks about models. New architectures, larger parameter counts, faster inference, those tend to dominate the conversation. But if you're actually building AI systems (or evaluating vendors), you quickly realize something else matters more: The data. Not just how much of it you have, but where it comes from, how it's processed, and how it evolves

Moderation has quietly become one of the hardest problems in modern apps. As chat, feeds, and real-time video interactions expand globally, the challenge isn't just catching bad content; it's doing it in real time, across languages, with context, and at scale. At Stream, we've been investing deeply in solving that problem. This roadmap is a

Chat looks simple. A user types a message, and it appears on the other person's screen. Ship it. At Stream, we know it's anything but. WebSockets. Persistence. Message ordering. Offline sync. Presence at scale. File uploads. Emojis. All of it is table stakes for any chat or messaging app, and all of it is a

TLDR; Live commerce is a trillion-dollar market, led by China's $680B in 2023 sales but growing fast in the U.S. with a 36% jump projected by 2026. The core tech stack matters more than the platform: low-latency video, real-time chat and moderation are what separate a polished experience from a broken one. Buyers who watch

TLDR; Each API has a different strength: Agora adapts video quality to network conditions, Enablex supports 2,000 participants, and Vonage lets you embed video with one line of HTML. Pricing models vary widely: per-participant-per-minute, tiered by video quality, or unlisted. Stream includes $200/month in free usage. Estimate your monthly cost before committing. If you're in

Real-time feeds are practically table stakes for modern applications. Users expect instant messaging, activity streams, and collaboration throughout a product. Product managers see competitors shipping these features and add them to the roadmap. Developers reach for WebSockets or start polling an endpoint. But real-time infrastructure that works in development often fails in production. Connections drop

Marketplaces only work when people trust each other. Buyers trust that listings accurately represent what they're purchasing. Sellers trust they won't be scammed, harassed, or pushed off the platform by bad actors. And both trust that the marketplace itself is actively protecting them, not reacting after damage is already done. As marketplaces scale, maintaining that

Stream has reached a major milestone in activity feed infrastructure, successfully benchmarking over 37 million operations with a 10% write and 90% read workload distribution across a dataset of 100M users, 500M activities, and 200M follow relationships. Each scenario was tested at 500, 1,000, and 1,500 requests per second to measure performance under increasing load.

Stream has reached a major milestone in real-time video infrastructure: Successfully scaling a single WebRTC-based livestream to 100,000 concurrent participants while maintaining ultra-low latency, stable frame rates, and zero packet loss.

An activity feed is an in-app feature that can take many forms, such as a news feed, content recommendations, or timeline in social and community-based applications. When successfully integrated, they can increase your app's user engagement and retention rates while lowering customer acquisition costs (CAC). But before realizing the full value of an activity feed,

Content moderation is the invisible infrastructure of the web. Every message sent, image uploaded, livestream broadcast, and marketplace listing posted passes through moderation systems that determine whether it reaches its intended audience. Get it right, and your platform becomes a thriving community where users feel safe to connect, transact, and create. Get it wrong, and

Adding in-app chat is one of the most common (and underestimated) product decisions teams face. Today, AI has made it easier than ever to prototype messaging features quickly. A small team can scaffold a working chat experience in days, not months. But shipping a demo is not the same as running a production chat system.

Stream has achieved a leading industry benchmark in scaling real-time chat as-a-service, supporting 5 million concurrent connections in a single chat channel. This engineering achievement underscores Stream Chat's position as the preferred in-app chat provider for enterprise organizations hosting the world's largest online events. Stream's infrastructure currently powers messaging and activity feed experiences for more

Online communities rely on moderation to function, yet every moderation decision carries significant ethical implications. The platforms that choose to remove, allow, promote, or downrank content directly shape culture, discourse, and safety. As AI systems take on more moderation responsibilities and regulatory scrutiny increases, the stakes continue to rise. Ethical moderation is no longer only

Push notifications, in-app bells, email digests, SMS alerts, chat mentions... Modern apps live and die by their ability to notify users at the right moment with the right message. However, building a reliable, scalable notification system from scratch is a massive undertaking. Between real-time delivery, cross-channel orchestration, personalization, compliance, and the sheer volume of events

As online platforms strengthen their safety frameworks, malicious users respond with increasingly creative ways to evade detection. The rise of content moderation circumvention is not a surprise. Modern apps support global conversations at scale, and as moderation becomes more effective, the incentive to outsmart it grows. But circumvention isn't increasing solely because moderation is improving.

Trust and safety teams sit at the intersection of user experience, legal risk, and community health. Yet many teams still struggle to answer basic performance questions like: Is our moderation platform actually catching harmful content? Are we overblocking and frustrating good users? Are our tools paying off in time and cost savings? The only way

Content moderation is at a critical juncture. The amount of user-generated content has exploded across chat, activity feeds, gaming environments, livestreams, and marketplaces. Every interaction has become an opportunity for connection, but also an opportunity for harm. At the same time, regulation is increasing worldwide, and user expectations for safety are higher than ever. Trust

What started as simple text-based chat rooms has exploded into a complex ecosystem of real-time interactions: livestreams with thousands of concurrent viewers, multiplayer games with audio rooms, dating apps with video calls, customer support chats, creator economy platforms, and virtual reality spaces where communication happens through gestures and proximity. This evolution presents a fundamental challenge

Numbers like these explain why so many teams want to build TikTok-style feeds, not just to

Content moderation has undergone a major shift in recent years. What once felt like an opaque black box to users has steadily moved toward openness, clarity, and accountability. Historically, a user who had content removed or an account restricted rarely received meaningful information about why the decision happened, who made it, or whether it could

There was a time when the only weapon in the chat moderator's arsenal was a simple keyword list. You would be adding new words and phrases to your filters as they came up, always in reactive mode. Maybe you have regexes to help. Perhaps you build out a team. But you're always chasing the latest

In today's economic climate, every dollar counts. Organizations are under pressure to maximize ROI on their tech stack and scrutinize vendor relationships. Specifically in the in-app chat service market, there has been a big shift away from technology that is not economically priced and does not effectively scale to meet business requirements. When considering a

These days, low-latency video streaming is so deeply embedded in current culture that, for those accustomed to TikTok, Twitch, YouTube, or even straightforward video chats, the idea that video could be anything other than millisecond-perfect seems ridiculous. Of course, all those platforms, and really the entire concept of video streaming and video chat, are only
