The brokerage landscape has been reshaped by a wave of innovative start-ups. While giants like Schwab and Fidelity manage trillions in assets, smaller platforms such as Robinhood, M1 Finance, and SoFi have pioneered transformative features. They introduced commission-free stock trading and fractional-share investing, services that are now industry standard. For investors seeking a user-friendly mobile app or online platform to trade stocks, ETFs, options, or cryptocurrencies affordably, these smaller brokers are compelling options.
Why Consider a Smaller Online Broker?
Smaller brokers are often the source of the industry's most significant innovations. Their influence is undeniable; the widespread adoption of zero-commission trading is a direct result of their disruptive models. These firms typically cater to self-directed investors who prioritize low costs, intuitive technology, and access to specific assets like crypto over a full suite of traditional investment products like mutual funds or bonds.
Top Small Online Brokers Compared
We evaluated four leading small brokers—Moomoo, Robinhood, Tastytrade, and Webull—based on their investment offerings, fees, tools, and services.
Investment Choices and Product Offerings
A key limitation of most small brokers is their lack of traditional securities. None of the brokers listed here offer mutual funds or corporate and municipal bonds. Only Tastytrade provides access to U.S. Treasury securities.
- Robinhood & Tastytrade lead in product diversity. They offer the broadest selection of fractional shares for stocks and ETFs. They are also the only two in this group that support cryptocurrency trading, with Robinhood offering 11 coins and Tastytrade offering four.
- Cash Management: Moomoo currently pays the highest rate on its cash sweep account at 5.1%, followed closely by Webull at 5%.
Trading Platforms and Technology
Most of these brokers were built with a mobile-first philosophy, resulting in highly functional and similar mobile and desktop experiences.
- Moomoo and Webull provide robust applications featuring built-in stock screeners, advanced charting with drawing tools, and cost-basis calculators.
- Tastytrade takes a different approach, offering highly sortable lists of securities instead of traditional screening tools.
Advisory and Managed Services
For investors who want some guidance, options are limited among these self-directed platforms.
- Webull's Smart Advisor is the sole automated advisory service in this group. For an annual management fee of 0.2% of assets, its algorithms build and manage a portfolio of ETFs tailored to one of six risk profiles.
Customer Service and Support
Investors should not expect the same level of support offered by large, established firms.
- None of these brokers have physical branch locations.
- Moomoo provides access to human representatives through its chat function.
- Robinhood offers a callback or email response upon request.
- Tastytrade utilizes a chatbot system that can eventually connect users to a live person.
Understanding Fees and Pricing
While all these brokers offer commission-free stock and ETF trading, their fee structures for other services can differ.
- Robinhood, the pioneer of no-commission trading, also charges no fees for options trading. Its "Robinhood Gold" subscription ($75 annually) offers perks like a 3% IRA match and a higher 5% interest rate on uninvested cash.
- Moomoo stands out with its $0 fee for stock options trades and a flat $5 rate for 10 index options contracts.

Frequently Asked Questions
What is a small online broker?
A small online broker is typically a fintech start-up or newer entrant to the brokerage industry that focuses on low-cost, mobile-first trading. They often specialize in specific assets like stocks, ETFs, and cryptocurrencies but may lack broader offerings like mutual funds or bonds.
Who are small brokers best for?
These brokers are ideal for self-directed investors, particularly those who are tech-savvy, prioritize low fees, and are primarily interested in trading stocks, ETFs, and options. They are less suitable for investors seeking comprehensive financial advice or a full range of traditional investment products.
Are there hidden fees with commission-free brokers?
While stock and ETF trades are commission-free, brokers can generate revenue through other means. This includes payment for order flow, margin lending, subscription services for premium features, and fees on certain complex transactions like options contracts.
Is my money safe with a smaller brokerage?
Yes, provided the broker is a member of the Securities Investor Protection Corporation (SIPC). SIPC protects up to $500,000 in securities and cash (including a $250,000 limit for cash) in the event of a brokerage's failure. It is crucial to verify a broker's SIPC membership.
Can I transfer my portfolio to a larger broker later?
Yes, you can almost always initiate an Automated Customer Account Transfer Service (ACATS) transfer to move your assets from a smaller broker to a larger one. Be aware that some brokers may charge an account transfer fee.
Do any small brokers offer retirement accounts (IRAs)?
Many now do. For example, Robinhood offers a traditional, Roth, and SEP IRA, even including a matching contribution for its Gold subscribers. It's important to check each broker's website for the specific types of retirement accounts they support.
