What is FlowsBuilt?

FlowsBuilt is a collection of focused SDKs that give your SaaS product the infrastructure it needs — churn prediction, consent tracking, referral programs, secure sharing, and AI spend controls — without building any of it yourself.

ChurnKit

Real-time churn prediction, risk scoring, and webhook alerts. Know who’s about to cancel before they do.

AckKit

Policy acknowledgment and consent tracking. Cryptographic proof that users accepted your ToS — without DocuSign.

GrowthKit

Referral program SDK. Unique codes, attribution, activation tracking, fraud detection — four function calls.

ShareKit

Shareable link and guest access SDK. Password protection, expiry, view tracking, and analytics for any resource.

BudgetKit

Per-user AI spend limits. Stop runaway free users from generating $300 Anthropic bills overnight.

​
How it works

  1. Get an API key from the FlowsBuilt Console
  2. Install the SDK for the product you need
  3. Start tracking events and user behavior
  4. React to signals via webhooks, risk scores, and compliance reports

​
Quick examples

import ChurnKit from '@vgpprasad91/churnkit-sdk'

const churn = new ChurnKit({ apiKey: 'ck_live_...' })

await churn.identify('user_123', { plan: 'pro', mrr: 4900 })
await churn.event('user_123', 'feature_used', { feature: 'export' })

const risk = await churn.score('user_123')
console.log(risk.tier)           // 'low' | 'medium' | 'high'
console.log(risk.recommendation) // 'User is healthy — no action needed.'
