Free HAZOP/LOPA Software — and We Mean It.

Now that we have your attention, let’s talk about why Kenexis® Open-PHA® is different.

Kenexis has built a best-in-class software application for facilitating and recording process hazards analysis (PHA) studies. Kenexis® Open-PHA® is a genuine leap forward in a category that has largely stood still for a decade. Most traditional PHA software vendors have done little more than refresh their interfaces while steadily raising prices — leaving users feeling trapped, their study data locked inside a proprietary platform with no easy way out.

The Customization Trap

Some tools offer database customization, which sounds appealing until you see the results: studies with different formats, different fields, and different structures across the same company. At the enterprise level, that inconsistency makes it nearly impossible to compare risk statistics or roll up results across facilities — exactly the kind of high-level analysis that drives good decisions.

A Smarter Approach: The Superset Model

Kenexis® Open-PHA® solves this with a standardized, superset data structure that contains all the fields and tables any user could need. Individual users can customize their view — showing only the fields and tables relevant to them — while the underlying database stays consistent across every study, every plant, and every industry. That consistency enables the roll-ups, comparisons, and dashboarding available in the Kenexis® Open-PHA® cloud version.

The data structure is published openly by Kenexis as a JSON schema, meaning third parties can read and integrate with Kenexis® Open-PHA® files directly. A relief valve management system, for example, could pull relevant data straight from an Kenexis® Open-PHA® study. Other software vendors could even import Open-PHA studies into their own platforms — though don’t count on legacy vendors rushing to make that easy. They prefer you stay locked in.

Actually Free. No Catch.

The desktop version of Kenexis® Open-PHA® is completely free — not a trial, not a limited promotion. Free now, and free going forward. Download the Windows, MacOS, or Linux version directly from our download page.
