# Environments

> Known Darpan runtime targets and what each is for.

Darpan runs in three contexts: local development, a hosted pilot or demo, and the production-equivalent hosted app. The local stack is fully documented here. Hosted environment details depend on the specific deployment and are documented separately.

## Local development

Local development supports behavior changes and validation.

| Service  | Default URL                      |
| -------- | -------------------------------- |
| Frontend | `http://localhost:5173`          |
| Backend  | `http://localhost:8080`          |
| JSON-RPC | `http://localhost:8080/rpc/json` |

## Hosted pilot or demo

*Documented separately.* Hosted environments support customer review, release smoke testing, and workflows that need stable external access.

<Warning>
  Published docs use placeholders for credentials, session cookies, CSRF tokens, and organization-specific endpoint values.

## Hosted Darpan app

*Documented separately.* The active pilot, demo, or release environment provides the hosted Darpan URL.
