A/B-test prices on real traffic

Stop guessing what to charge. Split visitors between price variants and let server-confirmed purchases pick the winner.

Deterministic bucketing — a visitor always sees the same price

Revenue attributed to variants via payment webhooks, not clicks

Roll out the winning price in one click, no code changes

MRR, LTV, churn and conversion funnels — streamed from ClickHouse and refreshed in seconds, for every paywall and every experiment.

And the rest of the stack

Bundled, no iframe

Distributed as @monetize.software/sdk. No remote code, no third-party iframe — passes Chrome Web Store review and works inside CSPs that block external scripts.

Built-in user auth

A full identity layer — email / password, OTP and OAuth (Google, Apple, Facebook, GitHub). One session shared across web, extensions and Telegram. Powers your whole app's login, not just the paywall.

Metered API gateway

Put any external API — OpenAI, translation, image models — behind a token-metered proxy. We verify the user, deduct tokens per call and keep your API keys server-side. Monetize usage with no backend of your own.

Headless REST API

Every endpoint is plain HTTP with a Bearer key — create checkouts, read prices and check entitlements from Python, Go, PHP or any backend. No npm, no JavaScript required.

React, Next.js, Telegram

sdk-react ships a provider, hooks (usePaywallAccess, usePaywallPrices) and declarative components. Headless /core export runs on Node, Bun and the Edge.

6 payment processors

Stripe, Paddle, Chargebee, Freemius, Overpay and Polar — all behind one API. Route traffic between them to minimise risk and keep checkout up.

Workflow

From npm install to checkout in three steps

No backend required for the fastest path.

Configure the paywall

Design the paywall, set prices, plug in Stripe / Paddle / Chargebee / Freemius / Overpay / Polar — all from the dashboard, no redeploy.

app.ts

const access = await paywall.getAccess('export')

if (!access.granted) paywall.open()

Gate the feature

Call paywall.getAccess() to check entitlements, paywall.open() to upsell. Webhooks, analytics and entitlement state — handled for you.

API

Three integration paths, one SDK

Pick by how much UI you want to own — switch later without changing your `paywallId`.

Drop-in PaywallUI: ready-made modal + built-in auth

Custom UI: your pricing page, our BillingClient + AuthClient

Headless: SDK /core on your server, your own auth — or plain REST

Not on a JS backend? The same endpoints work over plain HTTP — REST API for Python, Go, PHP, Ruby & .NET.

Works with your payment stack

Run multiple processors side by side — route traffic, fail over, optimise fees. Switch a provider in the dashboard, no SDK redeploy.

Overpay

Polar

Route traffic

Split checkouts across processors by weight, geo or plan — straight from the dashboard.

Fail over automatically

If one processor is down or a charge is declined, the next one picks it up.

Optimise fees & risk

Send each charge to the processor with the best economics for that market.

Ship AI features, skip the plumbing

Point your app at one endpoint and we proxy it to any AI provider — handling auth, anonymous users, abuse and per-user quotas on the way.

OpenRouterOpenAIAnthropicGeminiDeepSeekMistralReplicateand any other HTTP endpoint

Auth on every call

Your key never leaves our servers. Each request is checked against a signed user session before it reaches the provider.

Anonymous users included

Visitors get an identity and a balance on their first call — no sign-up. When they register later, their history and purchases carry over.

Abuse handled for you

Captcha and per-IP limits stop farmed anonymous accounts, and an input cap keeps a single oversized prompt from draining your budget.

Quotas that add up

Grant credits once at sign-up or top them up daily. Every call is metered atomically, and a failed one is never charged.
