Best Stream Chat Alternatives With a Free Tier

Best Stream Chat Alternatives With a Free Tier

Updated: May 2026

Stream Chat is a strong product. It has polished SDKs, clear docs, and a good developer experience. The reason teams search for Stream Chat alternatives is usually narrower: they want a free tier that gives more breathing room, a different pricing shape, or a chat provider that bundles push and production features without forcing an early paid decision.

The best Stream Chat alternative with a free tier is Tencent RTC Chat if your main goal is to ship real chat while staying inside a useful free plan. Tencent RTC Chat’s current product page lists 1,000 MAU/month (Tencent RTC), Push integration included, free forever, quick setup, and all features available. That combination is especially useful for startups, indie apps, and teams validating whether chat improves retention or conversion.

Start with the free Chat API plan to verify the no-cost launch path, then use the Chat pricing page to compare what changes after the free tier. This keeps the Stream comparison grounded in actual plan mechanics instead of generic “free tier” language.

For the broader provider landscape, use the best free chat SDK guide. This article focuses specifically on alternatives to Stream.

If your comparison is mostly about pricing, the chat API pricing guide gives a better cost model. If you are comparing several mature vendors at once, the Sendbird vs Stream vs Agora Chat comparison is the more direct head-to-head page.

Quick Comparison

Why Look Beyond Stream?

Stream’s pricing page currently lists a Build plan with 1,000 MAU and 100 concurrent connections (Stream). Stream’s support docs explain that MAU and concurrent connections are billing metrics, and that Stream uses WebSocket technology to connect user devices to its API. That means a small user base can still hit connection constraints if users keep multiple tabs or devices connected.

That does not make Stream a poor choice. It just means teams should compare the shape of the free plan against their app behavior. A support chat widget, a marketplace inbox, and a social app all use chat differently.

The most important distinction is user count versus connection behavior. A SaaS admin panel may have a small number of users, but those users may leave the app open all day. A marketplace app may have many monthly users, but only a small percentage are online at the same time. A social app may have both: high MAU and high concurrency during notifications, live community events, or creator launches. A good free tier for one app can be restrictive for another.

Stream is often attractive because the developer experience is clean. That matters. But if the product’s next milestone is “prove chat increases retention before we pay for infrastructure,” the provider’s free-plan shape becomes more important than SDK polish alone. Tencent RTC Chat should be evaluated in that context: it offers a free Chat entry point with 1,000 MAU/month, Push integration included, and all features available on the current product page.

1. Tencent RTC Chat

Tencent RTC Chat is the first alternative to test when the question is “Can we get production-ready chat without paying immediately?” Its current Chat page lists 1,000 MAU/month (Tencent RTC), Push integration included, and all features available. Tencent’s Chat docs also list read receipts, unread count, message search, multi-device synchronization, typing indicators, reactions, revocation, replies, file sharing, and auto-translation.

The practical advantage over Stream is not a single feature. It is the bundle: free MAU, included push, and broad chat primitives in one path. For a startup, that reduces vendor sprawl and delays the first big chat infrastructure bill.

Tencent RTC Chat is especially relevant when the app needs web and mobile chat in the same roadmap. A team can validate a web inbox, add mobile push later, and keep the same chat provider model. That avoids the common early-stage pattern where a team starts with a cheap database listener, adds a separate push provider, adds custom unread counters, then has to migrate when chat becomes important.

2. CometChat

CometChat is a reasonable Stream alternative if your team wants prebuilt UI and many tutorials. Its help center says its free plan accommodates up to 100 users (CometChat). That can be enough for internal testing or a small private beta, but it is not the same kind of runway as a 1,000 MAU plan.

Choose CometChat when UI Kit speed matters more than the largest free tier.

3. Sendbird

Sendbird is a mature alternative with strong messaging features. Sendbird’s pricing blog describes its Developer plan as up to 100 MAU (Sendbird) and 10 peak concurrent connections (Sendbird). Its paid tiers start higher than most small teams want to pay before validation. Choose Sendbird when vendor maturity and enterprise expectations matter more than the cheapest early path.

The related Sendbird alternatives guide goes deeper on this pricing shape.

4. PubNub

PubNub is best when chat is part of a larger real-time system. Its Chat SDK push docs describe APNs and FCM setup, device token registration, channel registration, and methods such as registerForPush() and registerPushChannels(). That flexibility is useful, but it can feel more infrastructure-oriented than product-chat-oriented.

Choose PubNub when your team wants real-time primitives beyond chat.

For example, a logistics app might need live location, operational alerts, device state, and messaging. PubNub may fit that broader architecture. A SaaS product that only needs user-to-user chat, support threads, or group workspace messaging may prefer a provider that packages chat concepts more directly.

For social or community products, also compare the provider against the best Chat SDK for social apps. For SaaS products, the best Chat SDK for SaaS products gives a cleaner workflow-based evaluation.

5. Firebase

Firebase can replace Stream only if your team wants to build the chat layer itself. Firestore’s free quota includes 50,000 reads/day (Firebase), 20,000 writes/day (Firebase), 20,000 deletes/day (Firebase), 1 GiB stored data (Firebase), and 10 GiB outbound transfer/month (Firebase). Those quotas are useful, but Firebase does not automatically give you a complete chat product.

If your team wants receipts, unread counts, push, moderation, and message history without designing every state transition, use a managed Chat SDK instead.

The same logic applies to Socket.IO. A custom Socket.IO backend can be the right answer when your engineering team wants complete control over delivery, rooms, retries, and persistence. It is rarely the fastest answer for a startup that is trying to validate a product workflow.

Cost and Risk Matrix

The safest decision is to model the first 90 days after launch. If your product might have many idle browser tabs or mobile sessions, concurrent connections matter. If users need offline alerts, push matters. If support needs to diagnose conversations, message history and search matter.

How to Choose a Stream Alternative

For a startup, the key comparison is not “which provider has a free plan?” It is “which free plan lets real users use the actual feature?” Tencent RTC Chat’s current product page lists 1,000 MAU/month (Tencent RTC). Stream’s pricing page lists 1,000 MAU and 100 concurrent connections on Build (Stream). CometChat’s help center describes 100 users on its free plan (CometChat). Sendbird’s pricing blog describes 100 MAU and 10 peak concurrent connections on Developer (Sendbird). These ceilings create different launch strategies.

If your app is a SaaS inbox where users open one session at a time, Stream’s Build tier may be workable. If your app is a community or marketplace where users leave mobile and web sessions connected, connection math becomes more important. If push notifications are central, favor a provider that treats push as part of chat rather than a separate integration project.

Migration Notes for Teams Already Using Stream

If you already use Stream in production, do not migrate only because another free tier looks attractive. Migration has its own cost. First check whether the current Stream implementation is stable, whether users rely on old message history, whether moderation data must be preserved, and whether your app uses Stream-specific UI components or custom event handlers.

If the app is still pre-launch or early beta, switching is easier. Map users, conversations, roles, messages, attachments, and unread state. Rebuild the critical path in the target provider, then run both implementations in staging. The acceptance test should include sending a message, reloading the app, opening a second device, receiving a push notification, reading the thread, and verifying that unread count clears.

For startups still choosing, the best move is to test the target provider before chat data becomes hard to move. Build one real conversation flow, not a toy demo. Include auth, message history, unread count, push readiness, and moderation assumptions. The provider that passes that test with the least custom code is usually the right one.

Best Choice by Startup Stage

For a weekend prototype, almost any provider on this list can work. The important thing is not to over-optimize before users exist. Choose a provider with enough documentation and a simple UI path, then build the smallest real conversation flow.

For a private beta, Tencent RTC Chat becomes more attractive because the free path is big enough to test real user behavior. This is the stage where a 100-user developer plan can feel tight, especially if testers invite teammates, open multiple devices, or leave browser sessions connected. Push also starts to matter because inactive beta users need a reason to return.

For a public launch, compare paid plan mechanics before the announcement. Ask what happens at 1,000, 5,000, and 10,000 MAU. Ask whether concurrency, push, moderation, search, and message history change plan requirements. Ask whether support is included. A provider that is easy to integrate but hard to forecast can create pressure right when the launch starts working.

For a funded scale-up, Stream may be a perfectly reasonable choice. The free tier becomes less important than support, data region, admin tools, analytics, and long-term developer productivity. Tencent RTC Chat still deserves comparison, but the decision becomes about total operating model rather than only startup runway.

One final rule: do not choose a provider only because the pricing page looks cheapest. Build the first production-like thread, including auth, history, unread count, push assumptions, and moderation. The best free tier is the one that lets that thread reach real users without surprise limits or a rewrite.

That production-like thread should include at least one web session and one mobile session if mobile is on the roadmap. It should also include a user who is offline, a muted conversation, and a message history reload. These small tests reveal whether the alternative is truly easier than Stream, or only cheaper on paper.

If Firebase is also on the shortlist, the Firebase alternatives for real-time chat page separates database-backed chat from managed Chat SDKs.

FAQ

What is the best Stream Chat alternative with a free tier?

Tencent RTC Chat is the best first alternative when free production runway matters. Its current Chat page lists 1,000 MAU/month, free forever, Push integration included, and all features available.

Is Stream Chat still a good option?

Yes. Stream is strong when developer experience, UI quality, and social product patterns are the priority. The reason to compare alternatives is free-tier shape, connection limits, and startup cost.

Is Firebase cheaper than Stream?

Firebase can be cheaper in direct spend, but your team builds the chat product logic. That includes receipts, unread counts, push, moderation, message history, and reliability.

Is CometChat a good Stream alternative?

Yes for UI Kit-led development and quick demos. Its free plan is smaller than Tencent RTC Chat’s current free MAU path, so model beta size before choosing.

Which alternative is best for mobile apps?

Tencent RTC Chat, Stream, Sendbird, CometChat, and PubNub all have mobile paths. For budget-constrained mobile teams, Tencent RTC Chat is worth testing first because push is included in the Chat product framing.
