Protocols

Mockly mocks 20 protocols from a single binary and config file. Each protocol section below covers its request matching options, response shaping, and any protocol-specific features (streaming, sequences, faults, etc.).

Protocol	Typical use case
HTTP	REST APIs, webhooks, static/HTML pages, record mode
Outbound Webhooks	Server-initiated callbacks fired by an HTTP mock
WebSocket	Realtime/bidirectional messaging
gRPC	Unary and streaming RPCs from a .proto definition
GraphQL	Queries, mutations, and subscriptions
TCP	Raw byte-stream protocols
Redis	RESP-protocol commands
SMTP	Inbound mail capture
MQTT	Pub/sub messaging for IoT
NATS	Pub/sub and JetStream messaging
SNMP	Network device management (GET/GETNEXT/SET, traps)
DNS	Name resolution records
AMQP	RabbitMQ-style message queues
Kafka	Topic-based event streaming
LDAP	Directory lookups and binds
IMAP	Mailbox retrieval
FTP	File transfer
Memcached	Key-value caching
STOMP	Simple text-oriented messaging
CoAP	Constrained-device (IoT) messaging
SIP	VoIP signaling

Every protocol shares the same core concepts — matching, templated responses, state conditions, and scenarios — documented once in Configuration; this section covers what's unique to each protocol.
