One-liner: Confirm a practical stack that supports fast delivery.
Time: 20 to 30 min
Deliverable: Stack Decision Doc

Learning goal

You will be able to: Select a stack that supports your MVP and constraints.

Success criteria (observable)

• The stack includes frontend, backend, hosting, and payments.
• The choice is justified with three reasons.
• The stack aligns with the time budget.

Output you will produce

• Deliverable: Stack Decision Doc
• Format: One page doc
• Where saved: Course folder under /generative-ai-2026-build-ai-apps-and-agents/

Who

Primary persona: Digital nomad choosing a stack Secondary persona(s): Contributors or collaborators Stakeholders (optional): Early users

What

What it is

A practical choice of tools you can ship with now. It balances speed, simplicity, and the required capabilities.

What it is not

It is not a future proof architecture plan.

2-minute theory

• Simple stacks ship faster and break less often.
• Fewer services reduce setup and maintenance overhead.
• The best stack is the one you can deploy today.

Key terms

• Stack: The set of tools used to build and run the product.
• Constraint: A limit like time, budget, or skills.

Where

Applies in

• Technical planning
• Build setup

Does not apply in

• Long term scaling plans

Touchpoints

• Repo README
• Deployment config
• Billing setup

When

Use it when

• You are ready to build
• You must decide the core tools

Frequency

Once per product idea, revisit after launch

Late signals

• You keep switching tools
• The project stalls due to setup

Why it matters

Practical benefits

• Faster development
• Clearer onboarding
• Easier debugging

Risks of ignoring

• Tool churn
• Slow progress

Expectations

• Improves: shipping speed
• Does not guarantee: scalability

How

Step-by-step method

1. List required capabilities.
2. Choose tools that match your skills.
3. Confirm hosting and payments.
4. Write three reasons for the choice.

Do and don't

Do

• Prefer tools with clear docs and tutorials
• Minimize custom infrastructure

Don't

• Choose tools only for hype
• Add services you cannot maintain

Common mistakes and fixes

• Mistake: Too many tools. Fix: Remove non essential services.
• Mistake: Stack does not support payments. Fix: Add Stripe from the start.

Done when

• Frontend, backend, hosting, and payments are defined.
• Reasons are written and specific.
• The stack matches the time budget.

Guided exercise (10 to 15 min)

Inputs

• MVP scope
• Skills and constraints

Steps

1. List required capabilities.
2. Pick tools for each capability.
3. Write three reasons for the stack.

Output format

Field	Value
Capability	Tool
Reason 1
Reason 2
Reason 3

Pro tip: A boring stack you can ship beats a perfect stack you cannot.

Independent exercise (5 to 10 min)

Task

Remove one tool and explain why the stack still works.

Output

Updated stack decision doc.

Self-check (yes/no)

• Does the stack cover frontend, backend, hosting, payments?
• Are the reasons tied to speed and simplicity?
• Can you build it with your current skills?
• Does it fit the time budget?

Baseline metric (recommended)
