For developers

# Looking to build with Cyoda?

Start on the open-source project — or join the Cyoda Cloud waitlist. Come back to cyoda.com when you need commercial support.

[Go to cyoda.dev](https://cyoda.dev)[Join the Cloud waitlist](/cloud)

Need enterprise support? [Talk to us](/contact)

WHERE TO START

## Three paths, one model

Cyoda keeps the same entity model across open source, cloud, and enterprise. No re-platforming wall as your requirements change.

Open source

### Run it yourself

Start locally with in-memory or SQLite, grow to PostgreSQL without changing your model. No vendor dependency.

[Go to cyoda.dev](https://cyoda.dev)

SaaS

### Cyoda Cloud

Fully managed Cyoda — coming soon. Managed control plane, your business logic runs in your code via gRPC.

Enterprise

### Commercial deployment

SLAs, procurement support, and regulated rollout. For teams taking Cyoda into production.

HOW IT WORKS

## Your code lives in a gRPC processor

Cyoda calls your processor when an entity transitions state. You handle the logic; Cyoda handles consistency, history, and delivery.

loan\_processor.py

```
# loan_processor.py
from cyoda.sdk import ProcessorContext, entity_processor

@entity_processor(entity_type="LoanApplication")
def on_credit_check(
    ctx: ProcessorContext,
    entity: dict,
) -> dict:
    """Runs when a LoanApplication enters CREDIT_CHECK state."""
    score = credit_bureau.fetch(entity["applicant_id"])

    entity["credit_score"] = score
    entity["eligible"]     = score >= 650

    ctx.emit_event("credit_check_complete", {
        "entity_id": entity["id"],
        "score":     score,
    })
    return entity
```
