FundingView vs arb.sh: 18 perp DEXs or 62 exchanges, and funding net of fees

The short answer

FundingView and arb.sh both rank funding arbitrage pairs, both are free to read without an account, and both have a backtester and execution-cost data. Three things differ. FundingView filters 18 perp DEX entries, while arb.sh lists 62 exchanges, 14 of them centralized. FundingView ranks by funding APR and takes a backtest cost you type in, while arb.sh puts Net in the screener row: settled funding after measured fees and slippage at your size. FundingView has averaging modes, a strategy score and a paid API, while arb.sh adds a price arbitrage screener and has no plans. Use arb.sh if a leg sits on a centralized exchange or you rank by what is left after costs. Stay on FundingView for an API feed, Carbon, or Robust and Median averages over a year.

Both rank funding pairs, and neither needs an account to read

FundingView and arb.sh both rank long/short funding pairs across perpetual exchanges, and both can be read free without an account. Each has a backtester for a chosen pair, an execution-cost page by position size and pair pages with funding history. Both list spot and perp pairs, where you buy spot and short the perp, and both cover real-world asset perps. The differences are which exchanges can be a leg, what the row subtracts before it ranks, and what sits behind a plan.

FundingView lists 18 perp DEX entries; arb.sh lists 62 exchanges

As of 6 October 2026, the exchange filters on FundingView hold 18 entries, every one a perpetual decentralized exchange (DEX); Carbon and CarbonTradFi are two of them under one brand. arb.sh lists 62: 48 DEX and 14 centralized (CEX), all on the exchange list. The two lists share 16 exchanges. Backpack is on both: arb.sh files it as a CEX, FundingView as a perp DEX.

Only on arb.sh

Only on FundingView

Carbon and CarbonTradFi, two entries of one exchange brand.

A pair with a Binance or Bybit leg cannot be built on FundingView. On arb.sh such a pair has its own page, like Hyperliquid vs Binance on BTC, which charts the funding spread and the price spread together and includes a position calculator.

FundingView ranks by APR; arb.sh ranks by what is left after costs

The FundingView dashboard ("Live Rankings") and its Best Strategies list rank pairs by funding APR. Execution cost has its own page, with slippage plus fees in basis points at $1K, $10K, $100K, $500K and $1M; the two largest sizes are Premium. In its backtester the cost is a field, "COST (BPS)", that you fill in yourself. arb.sh puts two columns in the screener row:

Paid 7d

Settled funding that actually changed hands over the period, not the rate currently advertised.

Net 7d

Paid minus taker fees and order-book slippage to open and close both legs at the stated position size.

Slippage is measured by walking the live order book of each market, not assumed. You set the size: the default is $10,000, and $100,000 and $1,000,000 are also measured. APR is a scale of the current rate, not a forecast. A pair that ranks high on APR can shrink once the fees and slippage of a large position come out, and Net shows that in the same row. The execution cost page lists the taker fee plus measured slippage at $10k, $100k and $1M on every exchange, and which exchanges can fill each size.

Where each backtest gets its cost, and how far history goes

FundingView

A symbol, the long and short exchange, a position size and the cost you type in basis points. Results for 1 day, 1 week, 1 month and 1 year; the 3-month, 6-month and 1-year windows are marked PRO, and custom periods are Premium.

arb.sh

The backtest runs up to 90 days, and nothing is typed in. Every line is itemized: settled funding received and paid on each leg, taker fees on entry and exit, order-book slippage measured for your size, and the net result, with the price spread between the exchanges and the drawdown.

FundingView pair pages chart APR history over 24 hours, 7, 30 and 90 days and All, and its History Explorer runs from 24 hours to All Time. arb.sh records settled funding as it happens and keeps it with no 30-day ceiling, including on exchanges that publish no funding history; there it starts on 18 September 2026, the day recording began. A backtest replays settled funding. It is not a forecast.

What else arb.sh has besides the funding screener

arb.sh has several pages beyond the funding screener, all free:

• The price arbitrage screener shows where the same perp trades at different prices on two exchanges, priced after costs.
• Market stats show DEX volume, open interest and market share over time.
• The points farm page shows which perp DEXs have no token yet and run points programs, and the airdrops page links each row to the exchange's own docs.
• Vaults lists the vaults that perp DEXs run, with TVL, 7- and 30-day return, drawdown and lock.
• News collects what perp exchanges announced this week, from their own channels.
• CSV exports cover the funding screener, the price screener and execution cost.

A Telegram bot answers funding and spread lookups and sends the alerts you set, and a Telegram channel posts a daily review.

What FundingView does that arb.sh does not

• A documented REST API with keys on Premium: 500 requests per 15 minutes, key expiry from 1 hour to 1 year. arb.sh has no API, only CSV exports and llms.txt.
• Carbon and Carbon TradFi.
• Averaging modes for historical funding on Best Strategies, over windows from 1 day to 1 year: Avg uses every data point, Robust caps extremes at p10/p90, and Median resists outliers.
• Execution cost at $1K and $500K, as well as $10K, $100K and $1M.
• A strategy score from 0 to 100, on Premium.
• Accounts for Premium and API keys, with sign-in by email code, Google or GitHub.

Stay on FundingView if your scripts pull funding through a keyed REST feed, if every leg you trade is a perp DEX and Carbon is one of them, or if you rank strategies by Robust or Median averages over a year or by a 0 to 100 score. Open arb.sh when a leg sits on a centralized exchange or when you want the cost at your size in the row.

What each site costs

arb.sh has no plans. Everything, including CSV export, is free with no account. FundingView plans, as of 6 October 2026:

Premium is a recurring subscription billed through Stripe and can be cancelled any time.
