About Welren

Technical code-compliant tools, in your browser

The platform

Engineering tools, in your browser.

Welren puts rigorous, technical code-compliant analysis on the web - no desktop license, no black box. Each tool applies the governing standards directly and shows its working, so you can trust the number and the path to it.

It pairs those purpose-built calculators with a private, self-hosted AI that actually understands engineering context.

Principle

Private by design.

Calculations run in your browser and your data is yours - gated by row-level security and explicit read-only / read-write sharing. The AI runs on hardware we own, so your queries never touch a third-party server.

Delivery

Edge-deployed globally - opens instantly from a rig in the field or an office in the city.

Engineering quality

Validated. Version-frozen.

Calculation engines are regression-tested against published worked examples and independent industry calculation reports, then frozen - a released method never drifts. Every result shows its inputs, intermediate values and governing limit.
