Analytics and monitoring decision
PolyScout
A capable developer can build a useful trader-watching tool (watchlists, parsing, alerts) but reproducing the fully polished product (mobile apps, historical curation, production polish) would take more time and operational work than a small single-person scope justifies.

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
- Index Polygon blocks and Polymarket activity → identify and rank traders by performance → persist wallet state and compute alerts → deliver push notifications and show watchlists in a UI.
What it still won’t have
- Polished mobile UX, polished cross-device notifications and app-store distribution
- Historical data curation and any proprietary performance scoring tweaks
- Brand, existing user accounts and support channels
- Operational telemetry and alert tuning at scale
What remains hard
- Product polish and ongoing maintenance
First-year cost

PolyScout does not publish a price we could read, so there is nothing to compare against. What building costs is below.

Runnable build prompt
Build a minimal PolyScout replacement: use Node.js for backend, Postgres for storage, and a React web frontend. Core features in scope: (1) a Polygon block indexer using a public RPC provider to fetch new blocks and Polymarket contract events, (2) a parser to extract trades and compute per-wallet metrics (realized/unrealized PnL, volume, win rate), (3) a scheduler/service that evaluates alert rules and stores alert history, (4) a REST API to serve leaderboards, wallet pages, and watchlists, (5) push notification integration (APNs or Web Push) and simple email alerts, (6) a React UI to follow wallets, view trades, and configure alert thresholds. Out of scope: mobile app store packaging, paid analytics dashboards, advanced scoring models, or high-volume horizontal scaling. Include error handling for RPC failures, idempotent block processing, data schema migrations, and unit/integration tests for parser, ranking, and notification logic.
How we checked
How the score was reached
- Partly verdict base52
- 2 cited sources+1
- 3/3 assessment runs agreed+4
- Evidence score57
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.
