+## Protocol Selection Guide
85
+
86
+| Protocol | Best For | Docs URL |
87
+|---|---|---|
88
+| **REST** | General-purpose APIs, CRUD, microservices | `/docs` (Swagger) |
89
+| **GraphQL** | Complex data queries, real-time subscriptions | `/graphql` (GraphiQL) |
90
+| **gRPC** | High-performance internal services, streaming RPC | `protobuf` binary protocol |
91
+| **JSON-RPC 2.0** | Lightweight RPC, wallet/web3 APIs | `/jsonrpc` |
92
+
93
+## Database Selection Guide
94
+
95
+| Database | Best For | Driver |
96
+|---|---|---|
97
+| **PostgreSQL** | Production OLTP, complex queries | Rust `sqlx-postgres` |
98
+| **MySQL** | Scalable relational workloads | Rust `sqlx-mysql` |
99
+| **SQLite** | Development, embedded, single-server | Rust `sqlx-sqlite` |
100
+| **DuckDB** | Analytical queries, Parquet, CSV | Python `duckdb` |
101
+| **ClickHouse** | High-volume column-store analytics | Python `clickhouse-driver` |
102
+| **MongoDB** | Document storage, flexible schemas | Python `pymongo` |
103
+| **Redis** | Caching, rate-limiting, pub/sub | Python `redis` |
104
+
105
+## Development Server
106
+
107
+After scaffolding, start the dev server with hot reload:
108
+
109
+```bash
110
+cd my_app
111
+justapi serve --reload
112
+```
