The core loop is small enough for a capable coding agent to produce a useful local version. For Plan to Eat, store recipes, drag them onto a calendar, and generate a shopping list. The hard boundary is browser clipping, mobile apps, sync, household sharing, and workflow polish, plus sync, integrations, and household adoption.

What you pay today, before any DIY hosting
high editorial confidence
Buildability by layer
Screens, forms, and focused interactions
The repeatable job the product performs
Availability and legality of required data
Uptime, queues, support, and maintenance
Security, compliance, and user confidence
The achievable core
- Store recipes, drag them onto a meal calendar, generate a shopping list, share or print the plan, and keep data portable and owner-controlled.
- Build a focused single-user workflow with real persistence, search, and export.
- A responsive interface with real empty, loading, success, and error states.
The parts a prompt cannot buy
- browser clipping, mobile apps, sync, household sharing, and workflow polish
- frictionless family sync
- retailer and smart-home integrations
- large recipe or product database
- Permissions, presence, and shared workflows are difficult to simplify.
- Connectors, OAuth flows, and vendor API changes require constant upkeep.
Why people still pay
People still pay for Plan to Eat because household apps survive when every family member actually uses them and the data stays current across devices. The recurring cost buys multi-user conflicts, reminders, notifications, imports, barcode data, smart-home APIs, backups, and long-term maintenance, not just the visible interface.
Permissions, presence, and shared workflows are difficult to simplify.
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 Plan to Eat
Context
**Plan to Eat** — Store recipes, drag them onto a calendar, and generate a shopping list. It currently costs $5.95/mo.
The core loop is small enough for a capable coding agent to produce a useful local version. For Plan to Eat, store recipes, drag them onto a calendar, and generate a shopping list. The hard boundary is browser clipping, mobile apps, sync, household sharing, and workflow polish, plus sync, integrations, and household adoption.
This brief describes a focused, single-operator replacement for the part of Plan to Eat 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
Store recipes, drag them onto a meal calendar, generate a shopping list, share or print the plan, and keep data portable and owner-controlled.
Build a focused single-user workflow with real persistence, search, and export.
A responsive interface with real empty, loading, success, and error states.
Requirements
Functional
Modern browser.
Local or self-hosted storage.
Optional email notifications.
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 a personal replacement for Plan to Eat in an empty repository.
Use Next.js 15, TypeScript, SQLite, Drizzle ORM, and a local-first PWA; do not offer alternative stacks.
The core loop is: store recipes, drag them onto a meal calendar, generate a shopping list, share or print the plan, and keep data portable and owner-controlled.
Make the first run work locally with one documented command.
Store all user data locally by default and make export straightforward.
Put secrets in .env, ship .env.example, and never commit credentials.
Create household members, shared lists, calendar items, recipes or inventory records, and assignments.
Provide fast mobile-first capture with large controls, offline queueing, and conflict-safe sync to one server.
Support recurring chores or events, reminders, completion history, and printable views.
Add CSV or JSON import and export plus photo attachments with clear size limits.
Allow private and shared items and make every change attributable and undoable.
Add backups, household export, member removal, and a simple invite code.
Include clear empty, loading, success, and recoverable error states.
Add input validation, safe filenames, and graceful handling of unavailable APIs.
Write focused tests for the core transformation and one end-to-end happy path.
Create a README with setup, architecture, permissions, data location, and backup steps.
Do not add accounts, billing, telemetry, analytics, or a hosted control plane.
Deliberately leave out retailer ordering and proprietary product catalogs.
Deliberately leave out broad smart-home integrations.
Deliberately leave out large public recipe libraries and polished native mobile clients.
Finish by running the tests and listing the exact commands used.
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:
Browser clipping, mobile apps, sync, household sharing, and workflow polish.
Frictionless family sync.
Retailer and smart-home integrations.
Large recipe or product database.
Permissions, presence, and shared workflows are difficult to simplify.
Connectors, OAuth flows, and vendor API changes require constant upkeep.
What you still own after launch
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: high. No independent one-shot implementation is linked yet.
