Screenshots

The Lab Guides panel open beside a running two-switch topology, showing Lab 4's step checklist and the list of later labs from loopbacks through BGP, VXLAN, and EVPN — 23 self-checking lab guides

An in-app SSH session on a SONiC switch running show ip bgp summary with two established neighbors, beside the running topology — In-app SSH and serial consoles

The DB Inspector querying APPL_DB on a running switch, with PORT_TABLE keys listed and one port's attributes expanded — CONFIG_DB / APPL_DB / STATE_DB inspector

The Packet Capture panel running tcpdump on a SONiC switch interface, showing live OSPF hello and LLDP packets beside the running topology — Per-interface packet capture

The Service Health panel listing the SONiC containers running on each switch, with the gnmi container's log expanded — Per-switch service health

Build Network Labs on Your Mac

Bramble runs on our custom-compiled SONiC image — currently the only SONiC image that runs natively on Apple Silicon. Design network topologies visually, launch them as real SONiC virtual switches, and SSH into any device with a single click. No Linux workstation or cloud server required.

Key Features

23 hands-on labs — LLDP and VLANs through BGP, VXLAN, and EVPN, each step self-checking against live device state, plus break/fix exercises with real injected faults
Visual topology editor — drag-and-drop switches and hosts, four bundled presets, or round-trip containerlab YAML in and out
Real SONiC on Apple Silicon — our custom-compiled image booting directly on Virtualization.framework in 60–90 seconds, no QEMU
See inside the network — in-app SSH and serial consoles, CONFIG_DB/APPL_DB/STATE_DB queries, per-interface packet capture to Wireshark, live BGP/LLDP link overlay
Drive it from your AI client — an MCP server exposing 20 tools so Claude Code, Cursor, or Codex builds and runs labs headlessly, with a tutor mode that coaches instead of solving

Why Bramble?

Network engineers and developers need to test configurations, learn protocols, and validate designs. Bramble eliminates the barrier of spinning up Linux VMs or renting cloud instances — just draw your topology and click play.

Available Now

Bramble is available directly from DendroLabs — a one-time purchase, no subscription.

Personal — $59 — for individual use, learning, and home labs

Your purchase includes the Bramble app and our custom-compiled SONiC image — everything you need to run your first lab.

Requirements

	Minimum	Recommended
Mac	Apple Silicon (M1 or later)	M1 Pro or better
macOS	14.0 (Sonoma)	15.0 or later
Memory	8 GB	16 GB or more
Disk	5 GB	10 GB or more

Intel Macs are not supported. Each SONiC switch uses 2 GB of memory and each Linux host 512 MB, so a two-node lab needs roughly 4 GB and the full EVPN fabric about 9 GB.

Bramble is notarized by Apple, so macOS opens it without an unidentified-developer warning. The app itself is a small download and fetches about 1.9 GB of VM images on first launch. Keeping the images separate means app updates stay small instead of re-downloading them every time.
