1. ProBors — best for combined congress + whale research
ProBors is built for researchers who want congress trades, whale transactions, market charts, signal scores, watchlists, and AI tables in one dashboard.
Choose ProBors if:
- You ask ad-hoc questions ("largest senate purchases last 10 days")
- You watchlists politicians and tickers together
- You want disclosure timing plus market context without tab overload
Skip if: you only need one politician per year and never use alerts.

2. Capitol Trades — best for simple, familiar tracking
Capitol Trades remains a default recommendation for readable politician trade history.
Choose Capitol Trades if:
- You want a known brand with minimal learning curve
- External charting and news are acceptable
- Whales and AI are not part of your process
Consider switching when: you repeat the same export + chart steps daily.
3. Quiver Quantitative — best for alt-data breadth
Quiver suits users who use multiple alternative datasets beyond congress.
Choose Quiver if:
- Lobbying, contracts, or other Quiver modules drive your edge
- Congress is one screen among many you already pay for
Consider ProBors if: congress + whales dominate your week.

4. Free trackers — best for casual lookups
Free sites work for low-frequency checks. They often lack:
- Reliable watchlist notifications
- Whale integration
- AI summarization
- Signal prioritization on busy filing days

- Compare last three trades: traded date, filed date, amount bracket
- Check if whales on that ticker are shown without leaving the tool
- Time how long it takes to get a sortable table of recent buys
- Decide if alerts matter for your schedule
