Amba is the agent-native backend for mobile apps: one backend — identity, engagement, gamification, economy, social, analytics, and infrastructure — that an AI coding agent provisions and wires in about 30 seconds over a hosted MCP server. Stream (GetStream) provides scalable APIs and pre-built UI for chat (1:1, group, channels), activity feeds, and audio/video, with advanced moderation add-ons. It’s a social/comms component, not a backend: as of mid-2026, no auth for your users, app data store, economy, content, or analytics — and its production tiers start high. What is an agent-native backend?
Amba vs GetStream, capability by capability.
● built-in · partial = limited / add-on · — not offered. “Agent installs the whole backend” means the MCP surface is an entire app backend, not read/write access to one product.
Which should you choose?
- You want chat and feeds as one module of a backend that also has auth, push, economy, and analytics.
- You don’t want a separate ~$499+/mo comms contract layered onto your stack.
- You want an agent to install social alongside the rest of the backend.
- You need the deepest, highest-scale real-time chat, feeds, or video with rich UI components.
- Heavy-duty moderation and proven performance at massive scale are requirements.
- You already have a backend and want a dedicated, proven comms layer on top.
A component vs. the backend it plugs into
Stream is chat, feeds, and video — and it’s excellent at them. But you still buy a full backend (auth, data, push, economy, analytics) around it and wire Stream to your users. Amba includes a social graph, feeds, and group chat (with read receipts and realtime subscriptions) already wired to your auth, content, and analytics.
Price floor
Stream’s production chat starts around $499/mo for 10K MAU, with feeds, video, file/storage, and advanced moderation as additional cost. Amba includes social/chat/feeds in posted per-project pricing alongside seven other surfaces, which changes the math for consumer apps where messaging is one feature among many.
Depth vs. breadth
For massive-scale messaging with rich SDK UI kits and enterprise moderation, Stream is deeper. For a consumer app that needs solid in-app communication as part of one backend, Amba’s bundled social module is usually sufficient and far simpler to operate.
Where does GetStream beat Amba?
Stream beats Amba flat-out on the depth, scale, and polish of real-time chat, feeds, and video — mature SDKs, rich UI components, heavy-duty moderation, and proven performance at massive scale that a bundled social module won’t equal. If communication is the core of your product, Stream is purpose-built.
Moving from GetStream to Amba
If chat/feeds are a feature rather than the product, Amba’s social module replaces Stream and folds messaging into the same backend as auth and push. If you need Stream’s scale or video, keep it and let Amba own the rest of the backend.
Pricing context: Stream: free under small thresholds, then chat production from ~$499/mo (10K MAU), feeds ~$59–$899/mo, video metered per participant-minute, plus storage/moderation add-ons. Amba: social included in Free, $20, $200 per project. Verify Stream’s current tiers.
