# BillDog: Everything to launch, grow, and engage.
BillDog is the growth platform engineered for modern app and SaaS teams. It consolidates dynamic AI-native paywalls, complete product analytics, event-driven messaging, AI micro-surveys, and authentication into **one unified user record and single SDK**—replacing 5 to 6 fragmented vendors at half the cost.
### ⚡ Core Capabilities
- **AI-Native Dynamic Paywalls:** Compiles visual paywall designs directly to native SwiftUI and Jetpack Compose views with 0ms webview lag. Includes StoreKit 2 & Google Play validation, regional PPP pricing, and instant A/B experiments.
- **Complete ClickHouse Product Analytics:** Sub-second queries across raw clickstream events, conversion funnels, and retention cohorts. Because telemetry and billing receipts share a single user ID, revenue metrics and LTV forecasting require zero third-party ETL.
- **Event-Driven Messaging & Journeys:** Native APNs/FCM push and low-latency in-app modals triggered automatically by user behavior and subscription state transitions.
- **AI Surveys & Churn Recovery:** In-app NPS, CSAT, and cancellation exit surveys with real-time sentiment scoring and automated win-back discount triggers.
- **AI Coding & Vibe-Coding (MCP Server):** Official Model Context Protocol (MCP) server for Cursor, Windsurf, Claude Code, and Claude Desktop to query live MRR, scaffold paywalls, and discover schemas inside your AI editor.
- **Authentication & Entitlements:** Biometric passkeys (WebAuthn), social OAuth, SAML 2.0 / SCIM, and offline cryptographic entitlement checks.
### 💰 Transparent, Developer-Friendly Pricing
- **Generous Perpetual Free Tiers:** Start at $0 with lavish free allowances across every module—including native paywalls, ClickHouse product analytics, developer auth, and in-app micro-surveys.
- **50% or More Tooling Savings:** Consolidating your stack into BillDog cuts your overall tooling and platform fee burden by half or more compared to individual point solutions.
- **Predictable Scaling:** Transparent, low-rate volume pricing with no punitive per-MAU penalties or hidden surprise invoices.
- **Zero-Risk Testing:** Full sandbox access and developer tools with no credit card required to build and test.
