Can MarketMaster be vibe coded?
Turns a researched website into reviewed ads, social posts, video, and email campaigns
A solo campaign generator that scrapes one site and prompts an LLM for coordinated copy is a realistic contained build. MarketMaster's paid value is the deeper research, multi-format media generation, deterministic quality gates, independent review, integrations, scheduling, and maintained publishing workflow.

medium editorial confidence

The repeatable job the product performs

The achievable core
- Read one public website, extract a campaign brief, generate coordinated channel copy, review it, and export the approved package.
- Automate a bounded research or reporting workflow using permitted data sources.
- A responsive interface with real empty, loading, success, and error states.
The parts a prompt cannot buy
- multi-model campaign review
- generated image and video assets
- live social and email integrations
- scheduled publishing and delivery history
- Connectors, OAuth flows, and vendor API changes require constant upkeep.
- The last 20 percent is sync, migration fidelity, speed, and edge cases.
Why people still pay
They pay to move from a website to a coordinated, reviewable, publish-ready campaign without maintaining research, media, validation, integration, and delivery infrastructure themselves.
Connectors, OAuth flows, and vendor API changes require constant upkeep.
The last 20 percent is sync, migration fidelity, speed, and edge cases.

Build brief — a focused alternative to MarketMaster
Context
**MarketMaster** — Turns a researched website into reviewed ads, social posts, video, and email campaigns. It currently costs $29/mo.
A solo campaign generator that scrapes one site and prompts an LLM for coordinated copy is a realistic contained build. MarketMaster's paid value is the deeper research, multi-format media generation, deterministic quality gates, independent review, integrations, scheduling, and maintained publishing workflow.
This brief describes a focused, single-operator replacement for the part of MarketMaster that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.
What you are building
Read one public website, extract a campaign brief, generate coordinated channel copy, review it, and export the approved package.
Automate a bounded research or reporting workflow using permitted data sources.
A responsive interface with real empty, loading, success, and error states.
Requirements
Functional
Website text extraction.
SQLite.
Hosted or local web app.
Data and integrations
LLM API key.
Each of these needs a real account, credential, or quota. Set them up before writing feature code.
Non-functional
Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.
Security: server-side secrets, validated input, and no credentials in the client bundle.
Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.
Portability: the operator can export their data and leave without losing it.
Implementation brief
Build me a personal AI campaign generator inspired by MarketMaster. Requirements:
Use Node.js 22, Express, server-rendered HTML, and better-sqlite3.
Run locally on port 4860 with no accounts, analytics, or telemetry.
Accept one public website URL and fetch only same-domain HTML pages.
Extract visible product, audience, pricing, proof, brand voice, and CTA text.
Show the extracted campaign brief in an editable approval form before generation.
Use one OpenAI or Anthropic model selected with variables in .env.
Generate one campaign containing three ad concepts, five social posts,
one five-slide carousel outline, one short-video script, and one email.
Keep every asset grounded in approved brief fields and flag unsupported claims.
Add deterministic checks for missing proof, vague CTAs, generic hype, and
platform character limits; show warnings beside each affected asset.
Let me edit, approve, and export the package as Markdown and JSON.
Save briefs and campaigns in SQLite with created dates and approval status.
Include fixture-based tests for extraction, claim flags, and exports.
Secrets stay in .env and fetched page text stays on the local machine.
Out of scope: image/video generation, multi-model review, OAuth integrations,
automatic publishing, scheduling, collaboration, billing, and hosted accounts.
Include a README with setup, model costs, robots.txt etiquette, and limitations.
Delivery standard
Inspect the repository first, then write a short implementation plan before writing code.
Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.
Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.
Include responsive layouts plus genuine empty, loading, success, validation, and failure states.
Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.
Add structured logs around every external call and return actionable errors without leaking sensitive details.
Write unit tests for the core logic and one automated test of the main user journey.
Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.
Acceptance criteria
A clean install starts the app using only the README and .env.example.
The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.
Invalid input, missing configuration, provider failure, and an empty database each have a usable state.
The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.
Tests, type checking, linting, and a production build all pass with no ignored failures.
No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.
Non-goals
Do not build these, and do not claim to have replaced them:
Multi-model campaign review.
Generated image and video assets.
Live social and email integrations.
Scheduled publishing and delivery history.
Connectors, OAuth flows, and vendor API changes require constant upkeep.
The last 20 percent is sync, migration fidelity, speed, and edge cases.
What you still own after launch
Secure credentials, rotate secrets, and handle provider rate limits.
Run migrations, backups, restores, and dependency updates.
Test the critical journey after every model, API, or hosting change.
Monitor failures and fix the edge cases a first prompt will miss.
Maintain every third-party integration as APIs and OAuth rules change.
Risk
**Operational risk.** The code is achievable; dependable data, integrations, and ongoing operations are the real cost.
Editorial confidence in this assessment: medium. No independent one-shot implementation is linked yet.

Before you start
Can MarketMaster be vibe coded?
Partly, if you narrow it. A solo campaign generator that scrapes one site and prompts an LLM for coordinated copy is a realistic contained build. MarketMaster's paid value is the deeper research, multi-format media generation, deterministic quality gates, independent review, integrations, scheduling, and maintained publishing workflow.
What can an AI coding agent reproduce from MarketMaster?
Read one public website, extract a campaign brief, generate coordinated channel copy, review it, and export the approved package. Automate a bounded research or reporting workflow using permitted data sources. A responsive interface with real empty, loading, success, and error states.
What will a DIY MarketMaster replacement still be missing?
multi-model campaign review; generated image and video assets; live social and email integrations; scheduled publishing and delivery history; Connectors, OAuth flows, and vendor API changes require constant upkeep.; The last 20 percent is sync, migration fidelity, speed, and edge cases.
What do I still own after building a MarketMaster alternative?
Secure credentials, rotate secrets, and handle provider rate limits. Run migrations, backups, restores, and dependency updates. Test the critical journey after every model, API, or hosting change. Monitor failures and fix the edge cases a first prompt will miss. Maintain every third-party integration as APIs and OAuth rules change.
