CoreBalance vs
JustETF
Do you need to find and compare the perfect ETF, or to manage and rebalance the portfolio you already own? They are two different jobs, and each tool does its own well.
CoreBalance
The free tool to manage and rebalance your portfolio
CoreBalance is not an ETF finder: it has no screener or fund database. It is the tool for the portfolio you already own: it calculates contribution-based rebalancing for free, imports your broker CSVs, keeps a transaction ledger with average cost, and runs local-first with no signup.
JustETF
The best UCITS ETF screener and comparison site in Europe
JustETF is the European reference for discovering UCITS ETFs: a powerful screener with detailed fund profiles, a fund comparison tool, and market data. Its portfolio planner with rebalancing and order lists is part of JustETF Premium, which is paid.
