Offline-First Inventory Software — Your Data Stays Local

Arc Manager is designed to run entirely on your computer.

There are no cloud servers, no required internet connection, and no accounts tying your data to an external service. Your inventory, BOMs, and costing data live on your machine — where you control them.

Why Offline-First Matters for Fabrication Shops

Fabrication work doesn't stop when the internet drops. Neither should your software.

Cloud-based tools introduce dependencies that shops don't need:

  • Internet outages
  • Server downtime
  • Subscription lock-in
  • Data stored on someone else's infrastructure

Arc Manager removes those dependencies by design.

You Own the Software. You Own the Data.

Arc Manager stores your data in a local database on your computer.

We don't have access to it. We can't see it, sell it, analyze it, or take it away.

There are no logins, no cloud sync, and no accounts required. Once installed, Arc Manager works independently of any external service.

Offline Doesn't Mean Limited

Offline-first isn't a fallback mode in Arc Manager — it's the core architecture.

Because everything runs locally:

  • The interface is instant
  • Calculations are immediate
  • Your data is always available
  • Nothing stops working if a service changes or shuts down

The software behaves like a shop tool, not a web service.

Designed for Reliability, Not Dependence

Arc Manager includes built-in tools to help protect your data without relying on the cloud.

You control when and where backups are stored. Your data remains portable and accessible without requiring an account or subscription.

Who Offline-First Is Built For

Arc Manager's offline-first design is built for fabrication and welding shops that:

  • Want full control over their data
  • Prefer tools they own outright
  • Don't want subscriptions or cloud lock-in
  • Need software that works regardless of internet access

If you treat software like a shop tool — not a service — this approach will feel familiar.
