SaaS Project Scope & Architecture Estimator
Configure your product archetype and required feature modules. Instantly estimate engineering delivery weeks, budget benchmarks, monthly cloud bills, and a custom Next.js tech stack specification.
Tailored Modern Tech Stack for Your Project
Next.js 16 (App Router) + React 19 + Tailwind CSS + Framer Motion
PostgreSQL (Supabase / Neon) with Row-Level Security (RLS) & Prisma/Drizzle
Supabase Auth / Clerk with JWT & Cookie Session sync
Stripe Checkout & Billing Portal with Webhook Idempotency
Vercel Enterprise or AWS ECS (Dockerized container)
Upstash Redis (Rate limiting & KV Session caching)
Suggested Delivery Roadmap
Phase 1: Architecture Spec & Database Schema
- Interactive Figma prototype alignment
- PostgreSQL schema with RLS policies & foreign key constraints
- CI/CD staging pipeline and environment secret vaults
Phase 2: Core Business Logic & Feature Modules
- Authentication, organization workspace switching, and session management
- Selected functional modules and third-party API integrations
- State management, optimistic mutations, and toast notifications
Phase 3: Hardening, Security Audit & Production Launch
- OWASP security header configuration & CSP validation
- Load testing, database index optimization, and Core Web Vitals audit
- DNS cutover, SSL provisioning, and 24/7 uptime monitoring setup
Webhook Race Conditions: Failure to implement idempotent webhook processing risks duplicate account credits or lost subscription access.

Frequently Asked Questions
Understanding web application development scopes, timelines, and budgeting.
How are the engineering weeks and cost ranges calculated?
Our calculator uses industry benchmarks derived from over 50+ production web engineering and SaaS builds. Each functional module (e.g. multi-tenant auth, Stripe subscriptions, AI pipelines) is mapped to required senior engineering days, plus baseline architectural scaffolding (database modeling, CI/CD, responsive layout tokens, and error handling).
What is included in the estimated monthly cloud infrastructure cost?
The cloud infra estimate accounts for baseline managed PostgreSQL database instances (e.g., Supabase or Neon Pro tier), production web hosting on Vercel or AWS ECS, transactional email delivery (Resend/SendGrid), error monitoring (Sentry), and Redis caching instances (Upstash).
How does JoinAffix structure web engineering sprints?
We operate in 2-week focused sprints with continuous daily deployments to staging. Every milestone includes automated end-to-end testing, OWASP security reviews, and direct Slack communication with the senior engineers building your application.
Can JoinAffix take over or refactor an existing codebase?
Yes. If you already have an MVP built with Next.js, React, Node, or an AI prototype from Cursor/Bolt.new, we conduct a rapid code audit and provide a refactoring roadmap to harden your application for production launch.
Have a web problemworth solving?
Whether you're building from scratch, modernizing a legacy system, or rescuing an unfinished AI prototype — work directly with the engineers who will build, fix, and run it.
