Quick Overview

Cascade

Cascade is a free, open-source SaaS starter kit based on the T3 stack (with Next.js + Prisma + PostgreSQL + TypeScript) that aims to give you a “ready-to-code business logic” foundation rather than a full-blown UI framework. Its core philosophy is minimal bloat. Once you clone the repo, provide environment variables and database config, you can have a working backend (auth, DB, basic flows) running locally in minutes. Cascade supports essential SaaS‑app plumbing such as authentication (via Auth.js / NextAuth + Prisma), database setup (PostgreSQL + Prisma), payments & billing (through Lemon Squeezy integration), background jobs (with Trigger.dev), error tracking (via Sentry), analytics (via self‑hostable or free‑plan friendly services like PostHog / Plausible), plus optional “business‑adjacent” pieces: a markdown-based blog via Contentlayer, email flows, server‑side rendering, and basic CI/CD / deployment setups.

ShipFlutter

ShipFlutter is a cross‑platform starter kit built on Flutter (with Dart), intended to help developers ship Android, iOS and web apps from a single codebase without starting from scratch. It combines frontend UI, backend setup, and common infrastructure so you can launch mobile + web apps faster. ShipFlutter delivers a fully customizable app scaffold including: authentication (email/password, social login, anonymous auth), responsive cross‑platform UI with theming and localization, navigation via GoRouter, state management via Signals, and Material styling. On the backend it offers integration with Firebase (Firestore, Functions, hosting, realtime updates) and optional AI/ML capabilities via Vertex AI useful if you plan AI‑powered features. For monetization or SaaS‑style apps, it supports payments: mobile IAP/subscriptions via RevenueCat and web payments via Lemon Squeezy. It also includes support for notifications, analytics/monitoring, feedback, offline‑ready data handling, and optional templates (for example UI templates, landing‑page/marketing‑page templates, even Tinder‑style or chatbot‑style UIs) enabling you to ship full‑featured apps quickly.
