## AfterFees vs Loris Tools: gross scanner or net after costs

| Feature | AfterFees | Loris Tools |
|---|---|---|
| Net result after fees and slippage at your size | Yes. Taker fees, order-book slippage on all four fills (open and close), borrow interest and capital cost, at the size and holding period you set (free: $10,000 for 7 days). | Gross, normalised to 8 hours; the page notes that fees and slippage may eat the spread. Its API can return slippage and fee estimates in basis points. |
| Capacity / maximum size | Shows how large each pair can go before open-interest caps or order-book depth become the limit. | Order-book depth and slippage data available through its API. |
| Settled-rate replay and history | Replay of settled funding over 7 days (free on pair pages), 30, 90, 180 and 365 days (Pro), with max drawdown, negative days, daily direction flips and a CSV export. | Settled funding history since September 2025, plus a backtester. Deeper than AfterFees. |
| Spot-perp and borrow costs | Spot-perp and reverse carry, with borrow rates from 5 centralised exchanges plus an Aave reference. | Focused on cross-exchange funding arbitrage; spot-perp with borrow costs not found in our review. |
| Basis and dated futures | Dated-futures basis on 9 exchanges, coin-margined included: spot or perp vs future on one exchange or across two, same-day futures across exchanges, calendars and term structure, net to delivery at your size. | Not found in our review. |
| Pendle Boros fixed vs floating | Locked fixed-rate net result at your size, with a term-matched benchmark, win rate and capacity. | Not found in our review. |
| Cross-exchange transfer (spot) arbitrage | Routes across 8 exchanges matched by chain and contract address (never by ticker): real-transfer and pre-funded net after both taker fees, order-book slippage and the withdrawal fee at your size, perp hedge cost, capacity, arrival estimate; stale wallet status is never shown as executable, closed-side spreads are listed as traps. | Not found in our review. |
| Exchange coverage | 50: 20 with full net calculation, 30 watch-only. | 43 to 44 venues and 1,731 coins, updated every minute, with Hyperliquid HIP-3 and HIP-4 data. More than AfterFees. |
