Rotki vs Zerion
Side-by-side comparison of features, pricing, ratings, and alternatives.
Rotki is an open-source portfolio manager for cryptocurrency holdings that runs locally on the user's own machine rather than storing account data on a third-party server. It connects to multiple exchanges and EVM-compatible blockchains to give a consolidated view of balances, trades, and DeFi positions without requiring users to share exchange API keys with a centralized service. The tool covers accounting-oriented features such as profit and loss reporting, staking analytics, and DeFi protocol tracking across liquidity pools. Because it is open source, the codebase can be audited by the community, and users can choose to self-host it entirely for maximum privacy.
Zerion is a self-custodial wallet and portfolio tracker that brings a user's tokens, NFTs, perpetual positions, and DeFi holdings across Ethereum, Solana, Base, Polygon, Arbitrum, and dozens of other chains into a single dashboard. It shows real-time balances and profit-and-loss on both spot tokens and perpetuals, and lets holders trade directly through built-in DEX routing that scans multiple liquidity sources for competitive pricing. Beyond tracking, Zerion offers copy trading to mirror top-performing wallets, live market data on trending tokens, and support for tokenized real-world assets. The wallet ships as an open-source browser extension, a web app, and iOS/Android apps, with Ledger hardware wallet support and audits from firms including Cure53, Zokyo, and SlowMist backing its security claims.
