What is Amba?
Amba is an agent-native backend for mobile apps. One backend covers identity, engagement, gamification, economy, social, analytics, and infrastructure, and an AI coding agent provisions all of it over a hosted MCP server in about 30 seconds. You describe the feature; the agent calls the tools; your app ships with the backend already wired.
One backend.
Auth, push, segments, content, gamification, economy, social, payments — all coherent, all in one place.
Built for agents.
A hosted MCP server with 450+ MCP tools across every domain. Your agent does the wiring. You ship the app.
Mobile-first abstractions.
Streaks, segments, daily content, leaderboards — abstractions that actually match how mobile apps work.
What you used to stitch together.
Now one backend.
Mobile-engagement abstractions out of the box. Every domain is a first-class API, an MCP tool, a typed SDK method, and a docs page — organized under seven canonical categories.
Identity
Users, sessions, auth flows, roles, api_keys.Engagement
Push, local notifications, email, segments, onboarding, content schedules, referrals, deep-links, tracked-links.Gamification
XP, achievements, streaks, leaderboards, challenges.Economy
Currencies, catalog, stores, inventory, subscriptions, entitlements, payments.Social
Friendships, groups, messaging, feeds, reviews, moderation.Analytics
Events, sessions, retention.Infrastructure
Collections (typed data + vector search), functions, sites, queues, media, secrets, configs, integrations, AI prompts.Firebase + OneSignal + AppsFlyer + a database + a weekend.
That stack works. It's also a vendor per feature, a console per vendor, and a bespoke streak service nobody loves. Amba collapses the lot — and pairs with RevenueCat for subscriptions: one prompt configures it, and entitlements cascade into segments, push, and XP.

Questions, answered in one breath.
What is Amba?
Amba is an agent-native backend for mobile apps. It bundles identity, engagement, gamification, economy, social, analytics, and infrastructure behind one API, one SDK family, and a hosted MCP server, so an AI coding agent can provision the whole backend and wire it into your code in about 30 seconds.
How does an AI agent install Amba?
Point any MCP-aware agent at https://mcp.amba.dev, or have it run npx -y @layers/amba init in your repo. The amba_developer_signup tool mints an account, a project, and API keys with no browser involved, and the agent then builds features with 475 MCP tools (as of June 2026).
What does Amba cost?
Amba pricing is per project: Free at $0 (1,000 MAU), Pro at $20 per month (25K MAU), Scale at $200 per month (250K MAU), and Enterprise by contract. Every tier includes all seven capability categories. Overages are linear and posted, and an optional spend ceiling caps the worst-case monthly bill.
Is Amba a Firebase alternative?
For the engagement layer, yes: Amba replaces the auth, push, analytics, and remote-config stack many teams assemble around Firebase, and adds streaks, segments, economy, and social as built-ins. Firebase still wins as a general-purpose datastore at very large scale. Read the full Amba vs Firebase comparison →
