Turns a smartphone video of an open trench into a centimetre-accurate 3D point cloud, CAD as-built plan and GIS-ready digital twin of buried utilities.
Key features
- Smartphone capture: Field crews record an open trench with a standard iPhone Pro — no specialist scanning hardware and no separate surveying appointment
- Centimetre-accurate point clouds: Reconstruction algorithms developed at ETH Zurich build a high-resolution 3D point cloud of the excavation from the video alone
- Standards-compliant CAD output: Generates as-built plans in DWG and DXF, with couplings and pipe runs identified and measurements simplified
- 3D digital twin and GIS export: Produces a model of the pipe route including building entries that drops into existing GIS systems
- Works without GPS: Captures basement sections and building entry points where GNSS-based surveying fails
- Immediate backfilling: Because capture takes minutes, trenches close right after filming instead of waiting on a survey crew
- Documentation in about 72 hours: Complete records arrive weeks earlier than conventional surveying, enabling prompt connection billing
- Third-party utility capture: Records crossing utilities and as-laid geometry as unbroken 3D evidence, replacing hand sketches
Best for
- A utility network operator documenting residential service connections without booking a surveyor for every site
- A contractor closing a trench the same day instead of leaving it open pending a survey appointment
- Capturing a building entry point in a basement where GPS-based surveying cannot get a fix
- A district heating project producing as-built DWG plans for regulatory sign-off
- Spotting a laying error in the 3D point cloud before backfilling, while the fix is still cheap
- Feeding as-built pipe geometry into a GIS system for long-term network maintenance planning

Terminal multiplexer and window manager in Go with BSP tiling, workspaces and agent state awareness for coding agents.
Key features
- Modal Terminal Panes: Vim-like modal interface with multiple panes and workspaces inside your terminal.
- BSP Tiling and Layouts: BSP tiling with preselection plus master-stack and scrolling layout modes.
- Agent Awareness: Coding agents in panes can report their state and message each other.
- Persistent Daemon: Keeps sessions alive and reaches sessions on your other machines.
- Kitty Graphics Support: Flicker-free kitty image passthrough with event-driven rendering.
- Hooks and Config: Run shell commands on window, session and agent events; customize keybindings and themes.
Best for
- A developer tiles several coding agent sessions in one terminal and sees what each is doing.
- An engineer keeps long-running terminal sessions alive across disconnects.
- A user manages sessions on remote machines from a single multiplexer.
- A team triggers shell hooks when an agent finishes or fails.
- A newcomer tries the real app in the browser through the WebAssembly guided tour.
- A power user customizes keybindings and themes for a vim-style workflow.
