Can I really build a SaaS in a weekend?
Yes, if the scope is right. These ideas are validated for weekend builds: simple tech, clear MVP features, and a defined audience. The goal is to ship a working product and get your first users, not build a feature-complete platform.
What tech stack works best for weekend projects?
Next.js + Vercel + Supabase is the fastest path. You get auth, database, hosting, and a frontend framework in minutes. Add Stripe for billing and Resend for emails. Ship on Saturday, get feedback on Sunday.
How much can a weekend project earn?
Weekend projects typically reach $1K-5K MRR. Some grow beyond that with iteration. The key is shipping fast, validating demand, then deciding whether to double down or move to the next idea.
