Infrastructure diagrams do not have to look like a ransom note of boxes and arrows: FossFLOW draws your network as a clean isometric map in the browser. Drag servers, routers, databases, and cloud services from the component library onto the angled grid, then link them with connectors that snap between nodes in click or drag mode. Multiplexed connectors bundle parallel links into tidy runs, rectangles and freehand annotations mark zones and notes, and text labels explain the flow. A diagram of a messy production network becomes a picture a new hire can read in one sitting. Work saves automatically every few seconds, exports to a JSON file you can keep in version control, and imports back just as easily. Run it as a shared team instance and diagrams persist on the server, filed under the project name, protected by optional basic authentication. The editor also installs as an offline-capable progressive web app, so the canvas keeps working on a plane and syncs nothing anywhere you did not send it. Documentation authors use the exported views in architecture guides, and engineers sketch proposals before touching real hardware.

TheOneFile Verse is a self-hosted workspace where teams draw networks, smart homes, and infrastructure together on one live canvas. Each room is a shared map where nodes, racks, wires, zones, and text sync instantly between everyone connected, with live cursors, per-room chat, and an undo that only reverses your own edits. Status probes cover ICMP ping, TCP ports, HTTP, and DNS, and Network Discovery scans a subnet, names hosts through reverse DNS, mDNS, and SNMP, tags more than 70 common services with selfh.st icons, and drops the results onto the map as nodes. An Enter 3D button turns any map into a walkable, multiplayer 3D space with procedural device models, and rack views show equipment mounted by U slot. The admin dashboard manages rooms, users, roles, invite codes, OIDC providers, SMTP delivery, email templates, backups, API keys, and audit logs. Rooms can carry passwords, guest access, or an automatic self-destruct timer. Anyone can export a portable copy as one self-contained HTML file, with optional AES-256 encryption, and import it back later to keep collaborating.
