What are the best free crypto trading bots?

Here's the landscape of crypto trading bots ranked by real usage (per DefiLlama, ranked by 24h fee revenue — the closest free proxy for how much people actually use each bot):

On "free": honestly, most of these aren't free — the bigger ones (GMGN, Trojan, Maestro) charge per-trade fees that fund that revenue. The standout genuinely-free option in this list is BONKbot — its own description is literally "Solana's FREE telegram tool, by the Bonk community, to trade any SPL token." So if free is your hard constraint, that's your answer. If you mean "free to download with fees only on trades," nearly all of them qualify.

Some quick notes to help you read this:

• Trading volume isn't shown for all of these — DefiLlama's derivatives/perps volume data requires a paid plan, so fees and revenue are the closest free proxy for real usage.
• GMGN is by far the most-used terminal right now (multi-chain: Solana, Ethereum, Base, BSC) — fast swaps, sniping, wallet tracking.
• Terminal is pump.fun's own advanced meme-coin terminal, so its volume is tied to the Solana meme ecosystem.
• Trojan and Maestro are the long-standing Telegram bots (sniping, copy trading, limit/DCA orders) — mature but smaller by usage than GMGN today.

A few honest caveats on trading bots as a category: they're built for speed on high-volatility meme coins, they charge fees that add up fast on frequent trades, and they don't remove the underlying risk of the tokens you're trading. This isn't financial advice — just the usage data and what "free" actually means for each one.
