Flysmart
A single knowledgeable developer can build and maintain a useful FlySmart replacement in a few weeks using existing OSS components; the product's durable advantages (data coverage, polished UX, enterprise SLAs) are not evidenced as unreproducible.

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
- Collect price observations for a route over time, compute a buy/wait recommendation and confidence, surface a 12-week price chart and optimal purchase window in a web UI, send an email alert when route meets target budget, and record the decision/validation trace.
What it still won’t have
- Proprietary historical coverage and any licensed data feeds FlySmart uses
- Polished UI/UX and built-in multi-user validation workflow at FlySmart parity
- Priority support, SLAs, and enterprise integrations (API on-demand)
- Any proprietary heuristics or curated route-specific tuning FlySmart may have
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal FlySmart replacement as a containerized web app using Python (FastAPI) backend, Postgres for storage, and a small React frontend. In scope: (1) a scheduler that snapshots prices for a route using a configurable scraper or flight-data API, (2) a Postgres schema storing route metadata and time-series price observations, (3) a simple statistical recommender that outputs buy/wait plus a confidence score and optimal window, (4) a React UI with route search, 12-week price chart, recommendation display, and audit trail pages, (5) an email alerting worker using SMTP or SendGrid when a target budget is met, (6) user sign-in (email/password), sharing of a recommendation to another user, and logging of who validated a recommendation. Out of scope: enterprise multi-site billing, large-scale crawling infrastructure, advanced ML model training, and third-party commercial integrations beyond email. Include error handling, retries for scraping/API calls, unit tests for core modules, and a Dockerfile + docker-compose for local deployment.

- 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.
