Why Your Side Project Fails (And the 1-Week MVP Framework That Works)

You've had the idea for months. You bought the domain. You set up the repo. You spent a weekend choosing between Next.js and Remix. Then... nothing.

Sound familiar? Here's why it keeps happening and how to break the cycle.

The 3 Reasons Side Projects Die

1. You're Building Features, Not Solving Problems

The first thing most developers do is open VS Code. Wrong. The first thing should be: Who is this for, and what pain does it solve?

If you can't fill in this sentence, stop coding:

[Person] struggles with [problem] and currently solves it by [workaround]. My app lets them [solution] instead.

2. You're Optimizing Before Validating

Nobody cares about your database schema when you have zero users. Ship ugly. Ship fast. Ship to one person.

3. You're Working Alone in Silence

Tell someone about it. Tweet about it. Post in a Discord. The moment you tell someone "I'm building X and launching on Friday," you have accountability.

The 5-Day MVP Framework

This is the exact framework PMML uses for rapid prototyping — both for our own products and for clients who need concept validation fast.

Day 1: Define (No Code)

Morning:
- Write the one-sentence pitch (template above)
- List 5 features the full product would have
- Cross out 3 of them
- The remaining 2 are your MVP scope

Afternoon:
- Sketch 3 screens on paper (landing, core feature, result)
- Choose your stack (use what you know, not what's trendy)
- Set up the repo and deploy an empty "Coming Soon" page

Day 2: Core Feature Only

Build ONLY the core feature. Not auth. Not payments.
Not the settings page. Not the admin panel.

Example - if building a URL shortener:
✅ Input a URL → get a short URL → redirect works
❌ Custom domains, analytics, team accounts, API keys

Commit and deploy by end of day, even if it's ugly.

Day 3: Make It Usable

Add the minimum to make a stranger able to use it:
- Landing page explaining what it does (3 sentences max)
- Basic auth (magic link or OAuth — don't build email/password)
- Mobile responsive (most first visitors come from social)
- Error states (don't let the app crash silently)

Day 4: Polish & Share

Morning:
- Fix the 3 most embarrassing UI issues
- Add one delightful detail (animation, emoji, copy)
- Write the launch tweet / post

Afternoon:
- Deploy to production
- Test on your phone
- Send to 3 friends for feedback

Day 5: Launch

Post to:
- Twitter/X (with a demo video or GIF)
- Product Hunt (if applicable)
- Relevant subreddits or Discord communities
- Your own blog (hello, SEO)
- LinkedIn (yes, people ship from LinkedIn traffic)

Then: STOP building and START listening.
Read every comment. DM every user. Watch session recordings.

The Tech Stack That Moves Fast

After 40+ MVPs, this is our default stack for speed:

| Layer | Tool | Why | |-------|------|-----| | Frontend | Next.js + Tailwind | Zero-config, fast iteration | | Auth | Supabase Auth / Clerk | 10-minute setup | | Database | Supabase (Postgres) | Instant API, realtime, free tier | | Hosting | Vercel | Push to deploy | | Payments | Stripe Checkout | 20 lines of code | | Email | Resend | Free tier, great DX | | Analytics | PostHog | Free tier, session recordings |

Total monthly cost to launch: $0 (all free tiers).

The Rules

1. No custom auth. Use a provider. Always.
2. No custom UI library. Tailwind + shadcn/ui. Done.
3. No optimization. That's a week 3 problem.
4. No perfectionism. Ship ugly on day 2. Polish on day 4.
5. No features without users. Validate before building.

What Happens After the MVP

If people use it: celebrate, then iterate based on feedback.

If nobody uses it: that's a win too. You validated in 5 days instead of 5 months. Move on to the next idea.

The worst outcome isn't a failed launch — it's 6 months of building in silence followed by a launch nobody notices.

What's your stuck side project? Reply with the one-sentence pitch. We'll tell you if it's viable and what to cut.
