PolyScope: what it does, what it costs, where it stops
Last checked 2026-09-08
PolyScope is a free Polymarket analytics dashboard at poly-scope.vercel.app built by a solo developer, manja316. It runs on a database that has collected Polymarket prices and order book snapshots every 15 minutes since late March 2026.
It pairs with a public dataset on GitHub, polymarket-historical-data, which packages 13,964 markets and 10.8M price records as CSV and SQLite under CC-BY-4.0.
What it does
The dashboard shows price charts, bid-ask spreads, volume changes, liquidity depth and order book snapshots across all active Polymarket listings, filterable by category and sortable by metric.
As of the June 2026 update the author reported "18.7M+ snapshots / 18,500+ markets," made up of 15.8M price rows and 1.58M order book snapshots, updated every 15 minutes.
The dataset's markets.csv carries metadata including volume, liquidity and pricing per market, and prices_sample.csv holds market_id, outcome, price and timestamp columns. Categories span politics, sports, crypto, geopolitics, economics, AI and science.
- Sources: Polymarket Gamma API for metadata and prices, CLOB API for order book depth
- Free tier of the dataset: markets.csv (13,964 rows) and a 100,000-row price sample
- Full dataset: SQLite with 10,820,040 price snapshots plus order book depth, $9, refreshed weekly
Pricing
The dashboard is free; the author writes that "The entire stack runs for free. The collector runs on a home machine." The full historical archive is $9 on Gumroad, and the sample files are free with attribution.
Venues and data
Polymarket only. Snapshots are 15-minute, so intrabar moves are invisible. The GitHub repo shows 2 stars, was created April 13, 2026 and was last pushed September 8, 2026.
The homepage of the repo points to a Gumroad listing rather than a hosted API, so the dashboard and the archive are two separate things: one to browse, one to download.
Where it falls short
It is a one-person project on a home machine. The hosted page loads as a JavaScript shell for non-browser fetchers, and the collector has no stated uptime commitment.
Fifteen-minute snapshots cannot support fill or slippage modelling the way minute-level books can.
The README says the dataset was last updated April 17, 2026, so verify the archive date before buying.
Who should use it
Researchers and hobbyist quants who want a broad, free Polymarket snapshot archive and are fine with 15-minute resolution. Traders who need minute-level books should pay a data vendor.
Questions about PolyScope
Is PolyScope free?
Yes. The dashboard is free; the optional full historical dataset costs $9.
How often does PolyScope update?
Every 15 minutes, per the author's write-up.
Does PolyScope have Kalshi data?
No. It collects Polymarket only.
Trackers find the edge. Calculators size it. Alerts time it.
When it is time to execute, the free Kairos terminal trades Kalshi, Polymarket and Predict.fun from one book.
