Why to Build with OpenAlgo?

"Why should I use OpenAlgo when I can just build my strategy directly on top of the broker's SDK or API?"

It's a common question. Many start with broker SDKs because it feels quick—just wire your signals and send orders. But soon, the pain points show up:

  • How do you monitor trades in real-time?

  • Where do you store and replay logs?

  • How do you test webhooks or strategies before going live?

  • How do you manage symbols, expiries, and contracts across brokers?

  • What happens when you want to switch from Broker A to Broker B?

That's when you realize the SDK is not enough.

OpenAlgo takes care of the heavy lifting.

It's not just an API wrapper—it's a full-stack, open-source trading automation framework designed to host strategies, manage brokers, and scale securely.
