Analytics and monitoring decision
BetterSlip
A narrow, self-hosted odds-scraping + alerting workflow is realistic for a single technical user to build and run, but reproducing a full commercial product with curated data partnerships, proprietary datasets, polished UX and support is not.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All BetterSlip alternatives, with the arithmetic →
What a replacement has to do
- Ingest odds and results, normalize and store them, compute edge/value opportunities, surface them in a dashboard, and notify on strong opportunities.
What it still won’t have
- Curated data partnerships and premium odds feeds
- Polished, productized UX and prebuilt strategies
- Proprietary models or historical datasets the vendor may include
- Ongoing customer support and legal/compliance effort specific to betting
What remains hard
- Product polish and ongoing maintenance

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal sports-odds analytics service using Postgres, FastAPI, and React. In scope: scheduled ETL worker to fetch and normalize odds from one public odds API, DB schema and migrations to store odds and results, background job to compute per-market edge metrics, REST endpoints to serve recent markets and computed edges, a React dashboard showing charts and a alerts list, and email/Slack alerting when edge > threshold. Out of scope: training proprietary ML models, paid odds partnerships, and compliance/legal advice. Include error handling, retries for API calls, unit tests for ETL and edge computations, and Dockerfiles + a deployment manifest for a single VPS.

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.
