# Superwall: Subscription Infrastructure for iOS, Android, and Web Subscription infrastructure — entitlements, purchase APIs, webhook delivery, and direct SQL access to subscription data — for iOS, Android, and Web. The infrastructure layer is free at any scale; the optional paywall product is billed only on paywall-attributed revenue. ## Pricing - **Infrastructure: free at any scale, every plan.** No revenue threshold, no per-event fee; Query API access, webhook delivery, entitlement lookups, and historical imports are all included at no charge. - **Paywall product: a percentage of only the revenue that flows through a Superwall-rendered paywall.** Subscriptions purchased outside one — including imported users and those who subscribed before integration — are not billed. Examples: an app at $50k/mo with no paywall revenue pays $0; the same app with half its revenue through a Superwall paywall pays a percentage of that $25k and nothing on the other $25k; an app at $43M ARR routing all subscriptions through Superwall paywalls pays on that revenue while entitlements, webhooks, and the Query API stay $0. ## Scale $1.5B+ annual subscription revenue across 10,000+ apps. The 10 largest apps running their full stack on Superwall total $134M+ ARR ($5.7M–$43.7M each). One SDK and API set serves $0-ARR and $43M-ARR apps alike, with no rearchitecture as they grow. ## Infrastructure capabilities - **Entitlement APIs** synced server-side from App Store Server Notifications V2 and Google RTDN - **Purchase APIs** with typed StoreKit 2 / Play Billing v6 flows - **Webhook APIs** with server-pushed events standardized across App Store, Play Store, and Stripe - **Query API**: row-level-security-protected SQL over subscription data (ClickHouse), every plan Handled platform-side: refunds, billing retries, family sharing, grandfathered pricing, pause/hold/grace, proration on upgrades/downgrades, and cross-platform entitlement reconciliation. ## Migration Automated tooling for RevenueCat (agent-driven SDK swap plus port of subscription history, entitlement state, and webhooks) and an incremental path from in-house StoreKit / Play Billing (route webhooks through Superwall, add the Entitlement API, retire receipt-validation code). ## Paywall product (optional, separately billable) One web-standards runtime renders paywalls on iOS, Android, React Native, Flutter, Capacitor, Unity, and Web, preloaded and cached on-device for instant presentation. Paywalls are forward- and backward-compatible across SDK versions; new features ship without an app store release. ## Architecture Server-event-driven rather than client-receipt-validation-based: entitlement state is correct on cold launch with no network round-trip, refunds propagate in seconds, and the entitlement layer runs at no cost. ## Docs * Migrate from RevenueCat: https://superwall.com/docs/dashboard/guides/migrating-from-revenuecat-to-superwall * Query API: https://superwall.com/docs/dashboard/guides/query-clickhouse * Webhooks: https://superwall.com/docs/integrations/webhooks * Pricing: https://superwall.com/pricing # Vibe Coding How to Vibe Code using the knowledge of the Superwall Docs ## Overview We've built a few tools to help you Vibe Code using the knowledge of the Superwall Docs, access your Superwall account, and more right in your favorite AI tools: * [Superwall Agents](#superwall-agents): An AI workspace for analyzing Superwall data exposed by connected tooling, reviewing experiments, working with available files, scheduling recurring reports, and connecting webhooks. * [Superwall Skill (Recommended for coding agents)](#superwall-skill-recommended-for-coding-agents): Gives AI agents live docs, API access, and step-by-step SDK integration guides. If you are working in an external coding agent, pick this one. * [Superwall MCP](#superwall-mcp): Expose your Superwall account (projects, paywalls, campaigns) to work with AI tools. * [Editor AI](#editor-ai): Build and refine a paywall directly inside the visual editor using AI Chat or an external MCP-compatible agent. And right here in the Superwall Docs: * [Superwall AI](#superwall-ai) * [Docs Links](#docs-links) * [LLMs.txt](#llmstxt) ## Superwall Agents [Superwall Agents](/docs/agents) is the dedicated Superwall AI workspace. Use it when you want to analyze experiment results, use selected Superwall organization context, work with files available to the active hosted machine, create charts and reports, suggest new experiments, schedule recurring prompts, or connect webhook-driven workflows. Use it from [superwall.ai](https://superwall.ai). Superwall Agents works with a hosted machine tied to your account, so you can run chats, Files, Terminal, automations, and webhook-driven work from the same Superwall workspace. Start with the [Superwall Agents docs](/docs/agents). ## Superwall Skill (Recommended for Coding Agents) The [Superwall Skill](/docs/dashboard/guides/superwall-skill) is the best way to give external AI coding agents full context on Superwall. It bundles live documentation, API access, dashboard links, and guided SDK integration flows for every platform, all in one install. If you are already working in Claude Code, Cursor, Codex, or another coding agent, pick this one. ```bash npx skills add superwall/skills ``` Once installed, your agent can look up any Superwall doc on demand, call the API to inspect your projects and applications, and walk through a complete SDK integration step by step. It supports iOS, Android, Flutter, and Expo out of the box with platform-specific quickstart skills. If you're only going to set up one tool, this is the one to use. See the full [Superwall Skill guide](/docs/dashboard/guides/superwall-skill) for details. ## Superwall MCP The Superwall MCP connects AI tools to your **Superwall account**, letting agents create and manage projects, paywalls, campaigns, products, entitlements, and webhooks directly. Instead of switching to the dashboard, your AI assistant can set everything up for you. If you also want live docs access and guided SDK integration help, use the [Superwall Skill](/docs/dashboard/guides/superwall-skill). The MCP is focused on account and resource management. See the full [Superwall MCP guide](/docs/dashboard/guides/superwall-mcp) for installation, a step-by-step quick setup, and the complete tool reference. ## Editor AI The paywall editor has AI tools for working on the paywall currently open in your browser: * [AI Chat Builder](/docs/dashboard/dashboard-creating-paywalls/paywall-editor-ai-chat): Open **AI Chat** in the editor sidebar, describe what you want changed, attach reference images, and let Superwall make draft edits for you. * [Editor MCP](/docs/dashboard/dashboard-creating-paywalls/paywall-editor-mcp): Connect Claude Code, Codex, Cursor, or another MCP-compatible agent to the live editor with a pairing code. Use Editor AI when the task is about changing the design, layout, products, variables, tap behaviors, navigation, or localization of the current paywall. Use the account-level [Superwall MCP](/docs/dashboard/guides/superwall-mcp) when the task is about creating or managing dashboard resources such as projects, applications, campaigns, products, entitlements, or webhooks. ## Superwall AI Superwall AI is available in the bottom right 💬 and is a great place to start if you have a question or issue. ## Docs Links At the top of each page of the Superwall Docs (including this one!): * **Copy Markdown**: to copy the page in Markdown format. Also in the **Open** dropdown menu, you can access these options: * **View as Markdown**: to view the page in Markdown format * **Open in ChatGPT**, **Open in Claude**: to open the page in the respective AI tool and add the page as context for your conversation You can also add `.md` to the end of any docs page URL to open that page as Markdown. For example, `https://superwall.com/docs/ios/quickstart/install.md`. ## LLMs.txt The Superwall Docs website has `llms.txt` and `llms-full.txt` files, in total and for each SDK, that you can use to add context to your LLMs. `llms.txt` is a summary of the docs with links to each page. `llms-full.txt` is the full text of all of the docs. | SDK | Summary | Full Text | | ------------------------- | --------------------------------------------------------------------------- | ------------------------------------------------------------------------------------- | | All | [`llms.txt`](https://superwall.com/docs/llms.txt) | [`llms-full.txt`](https://superwall.com/docs/llms-full.txt) | | Dashboard | [`dashboard/llms.txt`](https://superwall.com/docs/dashboard/llms.txt) | [`dashboard/llms-full.txt`](https://superwall.com/docs/dashboard/llms-full.txt) | | iOS | [`ios/llms.txt`](https://superwall.com/docs/ios/llms.txt) | [`ios/llms-full.txt`](https://superwall.com/docs/ios/llms-full.txt) | | Android | [`android/llms.txt`](https://superwall.com/docs/android/llms.txt) | [`android/llms-full.txt`](https://superwall.com/docs/android/llms-full.txt) | | Flutter | [`flutter/llms.txt`](https://superwall.com/docs/flutter/llms.txt) | [`flutter/llms-full.txt`](https://superwall.com/docs/flutter/llms-full.txt) | | Expo | [`expo/llms.txt`](https://superwall.com/docs/expo/llms.txt) | [`expo/llms-full.txt`](https://superwall.com/docs/expo/llms-full.txt) | | React Native (Deprecated) | [`react-native/llms.txt`](https://superwall.com/docs/react-native/llms.txt) | [`react-native/llms-full.txt`](https://superwall.com/docs/react-native/llms-full.txt) | | Integrations | [`integrations/llms.txt`](https://superwall.com/docs/integrations/llms.txt) | [`integrations/llms-full.txt`](https://superwall.com/docs/integrations/llms-full.txt) | | Web Checkout | [`web-checkout/llms.txt`](https://superwall.com/docs/web-checkout/llms.txt) | [`web-checkout/llms-full.txt`](https://superwall.com/docs/web-checkout/llms-full.txt) | To minimize token use, we recommend using the files specific to your SDK.
