Connect, simulate,
and test any connection
One console to forward ports, mock backends, echo traffic, drive requests and inject real-world network chaos — the big-eared bridge between your services.
docker runEverything between client and server
Forwarding rules
TCP, UDP and HTTP forwarders from any reserved port to any host, with live connection and byte counters.
Mock servers
Listeners that answer traffic instead of forwarding it — HTTP, WebSocket, raw TCP, plus MCP and LLM — matched by priority-ordered rules.
Network simulator
Break the network on purpose: latency, throttle, drop, corrupt, blackhole and close — stacked, scheduled and armed from the UI.
API client
Save, send and schedule HTTP & WebSocket requests server-side — with environments, history, monitors and a concurrent load mode.
Echo servers
Instant TCP or UDP echo listeners that mirror back whatever they hear — the quickest way to smoke-test a path.
MCP explorer
Connect to a Model Context Protocol server, discover its tools, resources and prompts, and invoke them live.
Reserve a port. Point it anywhere.
Hand out ports from 20000–20100 to forwards, echoes and mocks. Group them into projects, watch every byte cross the trunk in real time, then break the network on purpose to see what holds.
A real dashboard, not a config file
Put an elephant between
your services
Runs in Docker, zero config, no login. Reserve your first port in under a minute.
