openFTTH 0.1.0 beta

23 October 2026 · the first public beta for Windows

Installer · 132 MB Portable zip · 208 MB Release notes

Design automatically: Free and without AI: streets, homes, POPs, cabinets, FATs, every route, chambers, cable sizes and fibre assignment, checked against the rulebook.
AI crew (optional): Surveyor, Planner, Checker and Drafter on Claude CLI, Codex CLI, OpenRouter, any OpenAI-compatible key or a local Ollama model.
Manual mode: Add and move sites, draw, split and join cables, edit splices, draw keep-out and no-dig zones, then complete the network around your layout.
Design scenarios: GPON and XGS-PON budgets, centralised, cascaded and point-to-point, aerial spans on poles, façade routes, build phases and risers, priced side by side.
Deliverables: PDF plan sheets and a DXF drawing, BOQ per phase, cable schedule, port report, splice schedule, GeoPackage and export profiles.
Settings and updates: Theme, start-up mode, crew panel and cursors, every shortcut, and a check for new versions at start-up.
