It depends a lot, but I'll bite.

Assuming a fairly standard CRUD app:

App frontend: Netlify + Vue.js SPA, Tailwind CSS

Backend: REST server in Go, in docker, deployed wherever the hell is easiest. Probably k8s if I don't mind spending $50/mo because I'm super familiar with it and it will scale with me.

DB: Postgres

Cloud provider: GCP

Marketing blog: Hugo + Tailwind CSS

Source control: Github

Issue tracking: Github projects + Github issues

CI/CD: Github actions

Analytics: GA4 (Only if I want to feed Google optimize or Google ads) + Mixpanel

Payments: Stripe

Mail (API and marketing): Sendgrid

I've used a ton of different tools in most of these instances and these just happen to be my favorites for the "standard" use case.
