Comparison
Obside vs Composer
Composer lets you build or copy automated investment strategies with a no-code editor and run them hands-off in accounts it operates itself. Obside is an agent platform for the accounts you already have: it connects to your broker, answers in plain language, and runs agents for monitoring, backtesting and trading. The deepest difference is structural: Composer runs strategies inside its own brokerage; Obside works across your existing ones.
