Self-Hosted vs. Cloud Trading Bots: The Real Trade-offs
The choice is control against convenience. After the 2022 API-key leaks, it is also a security decision. Here is the full trade-off set.

What self-hosting buys you
Your API keys never leave a machine you control. No subscription. Full strategy freedom (Freqtrade, Hummingbot, Jesse, Octobot are open source; Gunbot and HaasOnline sell lifetime licenses). Communities document years of runs, and code you can audit.
What self-hosting costs you
A VPS ($5-20/mo), setup effort (Python, Docker, configuration), and the strategy work itself: public strategies mostly fail live, backtests overfit easily, and dry-runs for weeks are the recommended baseline. Users describe Freqtrade documentation as thorough but demanding. You also own uptime: if your server sleeps, so does your stop loss.
What cloud platforms buy you
Polished UIs, marketplaces of templates, one-click OAuth connections, mobile apps, support desks, and no ops. For non-developers this is the difference between running a bot and reading about one.
The hybrid worth considering
Exchange-native bots (Pionex, Binance, Bybit, OKX, KuCoin, Bitget, Gate) give you cloud convenience with zero third-party key exposure: the bot runs inside the exchange itself. For grid and DCA use cases they cover most of what the subscriptions sell.
FAQ
Is Freqtrade free?
Yes, fully open source (AGPL). Your only cost is the server it runs on and your time. Expect weeks of learning if you are not a developer.
Can I switch from cloud to self-hosted later?
Yes, but strategies rarely port 1:1. Plan a parallel dry-run period rather than a hard migration with live funds.
