Frontend
Next.js
Render the product shell, landing pages, dashboard screens, and stack/workflow surfaces with one codebase.
Best when you want one app that can grow from a simple MVP into a productized SaaS.
Lean launch stack
A lean stack for solo founders who need to validate, launch, measure, and monetize an AI product without building a heavy backend or a large operations layer.
Recommended layers
Frontend
Render the product shell, landing pages, dashboard screens, and stack/workflow surfaces with one codebase.
Best when you want one app that can grow from a simple MVP into a productized SaaS.
Hosting
Ship quickly with low ops overhead and a deployment path that solo founders can maintain.
Pick Cloudflare when edge cost and global delivery matter most; pick Vercel when Next.js convenience matters more.
Database
Store users, saved runs, generated outputs, workflow requests, and lightweight product state.
D1 keeps the stack simple; Supabase is better when you need a richer app database sooner.
AI layer
Power generation, summaries, prompts, and structured outputs for the first product workflows.
Use whichever model has the best output quality for the workflow, not whichever model is currently fashionable.
Send sign-in emails, product notifications, lead follow-ups, and export deliveries.
Important once users need confirmation, updates, or reusable workflow exports.
Payments
Handle subscriptions, credits, one-time sales, and upgrade flows without a custom billing engine.
Stripe is the default for flexible billing; Lemon Squeezy is simpler when you want less payment plumbing.
Analytics
Measure product activation, CTA clicks, exports, signups, and conversion quality.
Use product analytics when you need event-level decisions; use privacy-first traffic analytics when you mainly need clean basics.
Monitoring
Catch runtime errors, broken flows, and regressions before they become support work.
Best once you have real users and need reliable issue visibility.
Decision checks
One clear user journey from landing page to first useful output.
One conversion path that can be measured immediately.
One stack that is cheap enough to keep alive after launch.
One monetization path that does not require a custom billing system on day one.
Workflow fit
Positioning, MVP scope, landing page brief, stack choice, launch checklist, feedback loop, and monetization test.
The concrete services and providers that can actually run the workflow with low support cost.
