supastack
A SaaS boilerplate that ships auth, payments, AI, email, and SEO prewired for web, mobile, and desktop from one codebase.
What is supastack?
supastack is a SaaS boilerplate for building web, mobile, and desktop products from one shared codebase. It comes with Google and GitHub login, Stripe payments, AI streaming and usage tracking, transactional email, jobs, analytics, workspaces, and SEO tags already wired in. The page lists a Next.js web app, an Expo app for iOS and Android, and a Tauri desktop build for macOS and Windows, all sharing TypeScript modules.
It is aimed at founders and indie developers who want to skip the repeated setup of login, billing, email, a database, and deployment before working on the product itself. The page also offers a Supabase row level security generator, a pricing page generator, an i18n key checker, and a theme playground as free tools.
What sets it apart, according to the page, is that the foundation is meant to be set up once and reused across projects. Billing can be switched between adapters such as Paddle or Polar, AI providers such as OpenAI or Anthropic can be used with your own keys, and the project is open source on GitHub. The page describes a one-time purchase that allows unlimited personal and client apps.

on myskylight.com we have a much higher attach rate to the subscription because we can turn the subscription on automatically and we actually like pro tip here we give a discount on the hardware if you sign up with the subscription and that is a super successful way to get subscribers
Bundle hardware discount with subscription to lift attach rate
On the owned website channel, Skylight bundles a hardware discount with subscription sign-up so users pay less for the device today, get a free month, and full access. Most people do not opt out. This cannot be replicated on Amazon or in retail, giving the direct channel a structurally higher subscription attach rate. Hardware founders: use your own storefront to make the device discount the subscription acquisition mechanism.
We built a free online signature tool where you can type or hand-draw your signature and you can download it, and then we push them to go use that to sign documents.
Use A Free Utility As The Front Door So Users Activate Before Account Creation
Signaturely's first-time UX wasn't a signup wall — it was a free utility that solved a micro-task (creating a signature) before asking anything of the user. After users completed the small job, the product pushed them into the paid signing workflow, converting curiosity into account creation without a cold pitch.
There's a play for whatever you're stuck on.
