Vanguard offers both a wider range of investment types and accounts than Wealthfront. Plus, its product selection includes both self-directed investment accounts and automated or advisor-guided accounts. It's a better option for many investors. Wealthfront, on the other hand, best suits robo-forward investors who want to build wealth through automated investing accounts. In addition (and because Wealthfront is solely designed for robo-advice), you'll be able to utilize tax-loss harvesting, direct indexing strategies, crypto investments, and much more. The best choice for you depends on your investing goals and preferences.
