Documentation for Air-Gapped Environments
NeoArc Studio runs 100% offline as a desktop application with no licence servers, no telemetry, and no internet dependency. Designed for government, defence, and critical infrastructure environments.
Offline by Design, Not by Compromise
Most documentation tools assume internet access. Confluence requires a server. Miro requires a browser with connectivity. Draw.io's desktop version still phones home for templates and libraries. Organisations in government, defence, and critical infrastructure operate on networks with no internet connection, and they still need architecture documentation tools that work at full capability.
An Electron-based desktop application built for offline use from the ground up, NeoArc Studio runs every feature without internet: diagram editing with 5,385 icons, 100+ content blocks, schema editing with 47+ validation rules, REST API documentation, and local publishing.

Getting Started in an Air-Gapped Environment
Three editions designed for different operational environments: Connected for teams with internet access, Enterprise for regulated organisations with internal networks, and Sovereign for fully air-gapped defence and critical infrastructure deployments.
Source code escrow arrangements protect business continuity for organisations adopting NeoArc Studio as critical infrastructure. A third-party escrow agent holds the source code with defined release conditions.
For defence, intelligence, and critical national infrastructure clients, NeoArc offers full source code access enabling independent builds, supply chain verification, and security auditing.
Meet compliance requirements with Git-versioned architecture documentation, structured risk registers, traceable decision records, and data lifecycle blocks across SOC 2, GDPR, HIPAA, PCI DSS, and ISO 27001.
NeoArc Studio works entirely offline. No internet required, no cloud dependency, no subscription that can lapse. Your documentation capability is yours to keep.
Publish the same documentation to different audiences with publishing targets that control navigation, visibility, and layout. Deploy to local file systems for offline viewing or Azure for web hosting.
