Paying fees or commissions on your stock trades is a thing of the past. In 2026, almost every major investing app offers commission-free trading. However, “no fees” doesn’t mean all apps are equal. Some platforms have hidden fees, high margin rates, or markup costs on cryptocurrency transactions. Here are the best stock trading apps that offer true $0 commissions while giving you the best tools for your money.
1. Robinhood
Robinhood was the pioneer of fee-free trading. It offers $0 commission trades on US stocks, ETFs, options, and cryptocurrencies. There are no account maintenance fees or inactivity fees.
2. Webull
Webull matches Robinhood’s fee structure with $0 commissions on stocks, ETFs, and options. It also has no account minimums. Webull is a favorite among active traders because it provides free access to advanced charting tools that other brokers charge for.
3. Fidelity
Fidelity is a traditional powerhouse that offers a modern, commission-free mobile app. Unlike newer fintech apps, Fidelity does not participate in payment for order flow (PFOF) on stock trades, meaning you often get better execution prices. It also offers zero-expense-ratio index funds (Fidelity ZERO funds), making it completely free to build a mutual fund portfolio.
What to Watch Out For (The “Hidden” Costs)
Even with $0 commissions, brokers make money in other ways:
- Payment for Order Flow (PFOF): Some brokers route your orders through market makers, which can result in slightly worse execution prices.
- Margin Rates: If you borrow money to trade, check the interest rates. They can vary significantly between brokers.
- Premium Subscriptions: Apps like Robinhood charge monthly fees for premium accounts (Robinhood Gold) which unlock additional features.
For most beginner and long-term investors, Robinhood or Fidelity offers the best fee-free experience.
