Troubleshooting the desktop app

Resolve missing toolchains, blank windows, and release-signing failures before they block a build.

Ask about this guide
Open in

Setup and configuration

On Windows install the C++ Build Tools with the Windows SDK and the WebView2 runtime. On macOS install the Xcode command-line tools. On Linux install the WebKitGTK, compiler, tray, and system packages listed for your distribution. Install Rust with rustup, reopen the terminal, and run cargo check before starting Tauri.

A blank window usually means SUPASTACK_APP_URL is unreachable or points at a stopped dev server; the offline banner appears when the loaded page loses the network. Confirm the URL opens in a browser on the same machine and that you built with the intended value.

Implementation workflow

Release failures usually come from signing, notarization, or the updater block. Check the certificate and keychain on macOS, the signing certificate and timestamp server on Windows, the updater public key and endpoint path, and the product identifier. Re-run the release-config check, then install the artifact on a clean machine instead of over the development build.

Verification and troubleshooting

The app launches, reaches the backend, and installs cleanly.

Frequently asked questions

14 questions

What is supastack?

supastack is a modular foundation for building AI-powered SaaS products. It brings together common infrastructure so you can focus on product-specific features.

Does it support web and mobile?

Yes. supastack includes Next.js and Expo apps as starting points for web and mobile experiences.

What authentication is included?

Better Auth covers email OTP, magic-link, and social sign-in; email/password stays available at the API layer and through the Auth.js credentials engine for products that need it. Personal workspaces are provisioned with the account so product records stay scoped from day one.

How does it support AI?

supastack includes configurable multi-provider AI, usage tracking, budgets, and encrypted bring-your-own-key support.

How are subscriptions handled?

For products built on the kit, Stripe billing, subscriptions, and entitlements form the paid-access foundation. Provider secrets stay server-only.

Where does my product-specific code live?

Product-specific features remain in a separate codebase while the product configures and integrates supastack’s foundation modules.

How does supastack pricing work?

The kit is a one-time purchase with lifetime updates: Single Stack at $249 — your pick of Next.js (Web), Expo (iOS & Android), or Tauri (macOS & Windows Desktop) — Dual Stack at $398 with any two repos, or the Full Bundle at $399 with all three repos and the full monorepo, plus $75 per extra developer seat. No kit subscription. Checkout on this site delivers your license key by email, with repository access via GitHub invite.

How do workspaces scope my data?

User-owned records are scoped by workspaceId. Identity, entitlements, AI usage, billing events, and audit entries stay inside the personal workspace boundary.

How do background jobs work?

Trigger.dev is the explicit job runtime. The JobRunner contract only promises enqueue, status, and cancel—workflow semantics stay Trigger.dev-specific and explicit.

How is email different from outreach?

Transactional email covers product workflows such as completion notices. Cold outreach and campaigns are product concerns outside this kit’s email module.

How do mobile purchases work?

Mobile includes native purchases and restore through RevenueCat, with access verified by your server. Configure the store accounts and complete device testing before release. Web billing remains separate.

Where do AI provider keys live?

Bring-your-own-key credentials are encrypted and stay server-only. Keys are redacted from logs; usage and budgets remain visible at the workspace level.

Which payment methods does checkout accept?

The Stripe-hosted checkout accepts cards and can also offer Alipay and WeChat Pay once those wallets are enabled on the Stripe account — handy for buyers in China. Wallet authorizations confirm asynchronously, so the license page updates as soon as the payment clears.

Can I get a refund?

After you've got access to the repository, supastack is yours forever, so it cannot be refunded. But rest assured, you get the complete source code with lifetime updates to build and ship unlimited products for yourself or clients. You just cannot resell the code or redistribute the repository as a starter kit or template. One exception is the launch cashback — launch a live product built with supastack, share it, and reach 5,000 organic views or 50 organic likes within 60 days to get 50% of what you paid back; see the terms.
