Gravity
PaidNode.js and React SaaS boilerplate — multi-tenant accounts, subscription billing, a REST API with token auth, an admin dashboard with metrics, user impersonation, and a scaffolding CLI. One codebase for web and mobile. Paid, one-time license.
Why we recommend Gravity
Gravity has quietly served the Node/Express + React mainstream since 2019 — the stack of the enormous cohort of developers who never moved to Next.js meta-frameworks. It ships the full commercial checklist (multi-tenant accounts, plans and metered billing via Stripe, social sign-in and 2FA, transactional email, feature flags) plus things its competitors skip: an owner-facing admin dashboard with revenue metrics, user impersonation for support, and a scaffolding CLI that generates views and API routes. The API is a plain, documented Express REST API — trivially consumable by the included React Native companion app or anything else.
Best use cases
Best for: developers on the classic Node + React (non-Next.js) stack, products that need a real REST API for web + mobile clients from one backend, and founders who want built-in ops tooling (metrics, impersonation, logs) instead of wiring five SaaS dashboards together.
Honest limitations
Not for: teams standardized on Next.js/server components — Gravity's SPA + API architecture is a different worldview. Paid one-time license, closed-source, one maintainer. The UI layer is functional rather than fashionable; expect to restyle for a consumer-facing product.
