Most of the major brokers have free trades now for stocks and ETFs - Schwab, TD Ameritrade, IBKR, etc. If you're trading something more advanced like options or futures, you'll pay some small fees (options at Robinhood are free, they don't do futures). But when you're trading options, it's probably worth it to pay the fee for a more stable broker so you don't get wiped out by a Robinhood. The fees are very small by the way, for example I use Schwab and it's just $0.65/contract, which basically means for each share I pay a $0.0065 premium.
