# 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.

## Which one should I open?

## 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.
