Plateful: Meal Plan & Budget
A technical user can build a useful DIY replacement for shared lists and budget tracking, but reproducing robust, maintained real-time price coverage across many retailers (the product's core differentiator) is substantial ongoing work and operational cost.

No pricing page we fetched carried a figure, so there is nothing to compare against. The build side is still real.

No published price to break even against.
No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Browse a store website, add items to a list with their prices, see running budget totals, and share/update lists in real time.
What it still won’t have
- Out-of-the-box, maintained real-time pricing coverage for many retailers (Walmart, Target, ALDI, Costco, etc.)
- Polished mobile UX and App Store presence
- Existing user base and incremental product improvements driven by usage
- Ongoing store-specific scraping heuristics and reliability built up by the vendor
What remains hard
- Product polish and ongoing maintenance
First-year cost

Runnable build prompt
Build a minimal cross-platform grocery list app that supports browsing arbitrary retailer pages to add items with extracted prices, per-list budget tracking, and real-time shared lists. Stack: React Native for mobile, Node.js + Express for backend, Postgres for persistence, Firebase Auth (or Sign in with Apple/Google) for authentication, and Playwright running in a small worker pool (behind residential/rotating proxies) for store page scraping. In-scope features: (1) store browser UI that accepts a store URL and displays parsed product titles and prices; (2) list CRUD and item add/remove; (3) per-list running budget total and alerts when nearing limit; (4) real-time sync of lists between users; (5) background job to refresh prices on demand; (6) basic account settings and sign-in; (7) error handling, rate-limit/backoff for scrapers, logging, and unit/integration tests. Out of scope: replicating vendor's full catalog of retailer-specific parsers for dozens of stores, mobile App Store submission polish, and advanced ML-based item matching. Provide CI, Docker deployment manifests, simple monitoring/alerting, and documented runbook for updating scrapers.

- Evidence score56
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
