Poolfish and Metrix: Which to Use, and When
Poolfish is now part of Metrix Finance. Use Poolfish for a quick estimate on a Uniswap v3 range, and Metrix to test a range on real price history, track what a position earned, and watch lending.
Updated October 19, 2026. Poolfish is now part of Metrix Finance, so this post no longer weighs them as rivals. It explains which one fits which job.
Use Poolfish when you want a quick fee and APR estimate for a Uniswap v3 range, or a list of top pools to start from. Use Metrix when you want to test a range against real price history, work with Uniswap v4, or see what your live positions and lending actually earned. Poolfish's pool data now comes from Metrix.
What is Poolfish for?
- An estimate for one range. Pick a network, a pair and a fee tier, set your range, and the calculator estimates fee returns, APR and impermanent loss from how much of the pool's liquidity your range would hold.
- A list of top pools. Browse concentrated liquidity pools by exchange, with data from Metrix refreshed daily.
- Calculators for other exchanges, among them PancakeSwap, Orca, Aerodrome and Raydium.
An estimate is a starting point. It assumes trading carries on as it has, and it cannot tell you what a position will actually earn.
What is Metrix for?
- Testing a range on what really happened. Metrix backtests a range against the price action that actually took place, so you see whether it would have stayed in range before you deposit.
- Uniswap v4 and more exchanges, including Aerodrome, Velodrome and Solana exchanges, alongside Uniswap v3.
- What a live position earned. Paste a wallet address and every position reports its fees earned and time in range. Nothing to sign. Comparing a position with simply holding is part of the paid plans.
- Lending in the same place. Supply and borrow rates on Aave, Compound and HyperLend, and for your own lending positions the interest earned, what is borrowed and the health factor.
- Alerts. Price and lending alerts come with the paid plans.

What happened to Poolfish Pro?
Poolfish Pro is no longer sold. Existing subscribers move to Metrix Pro and keep paying their current Poolfish rate.
Why are they one family?
Poolfish began as Uniswap.fish, built by an independent developer with a Uniswap Foundation grant. The first version of Metrix was built from a fork of Uniswap.fish, and in August 2026 Poolfish joined Metrix Finance. One tool now does the quick estimate, the other does everything after it.
Estimate a range on Poolfish, or test it on real price history in Metrix.
