The software is free. The LCAs are not.

openLCA is described as user-friendly and intuitive, and relative to other expert LCA software that claim is fair. In absolute terms, it still requires genuine LCA expertise. You need to understand unit processes, reference flows, allocation methods, impact assessment selection, and how to map real product data to abstract database activities. The interface is an expert interface because the job it helps you do is an expert job.

Devera takes the opposite approach. The user provides product data, either by pasting a URL, uploading a PDF specification, or filling a short form. The AI handles the mapping to Ecoinvent activities, the gap filling for missing data, and the calculation. The user then reviews the result in a readable dashboard, adjusts anything that looks off, and exports. No unit process tree is built by hand.

The result is methodologically equivalent. A product carbon footprint in Devera uses the same emission factors, follows the same ISO standards, and is just as traceable as the same analysis built by hand in openLCA. What changes is the effort and the profile of the person who can produce it.

A meaningful LCA needs Ecoinvent or an equivalent database. openLCA does not include Ecoinvent. You license it separately, and the terms depend on your user type and scope. Academic and faculty licenses are more affordable or free, which is why openLCA works well for research. For commercial users, the pricing is different and is set by Ecoinvent directly.

Devera includes Ecoinvent 3.9.1 in every plan, along with AGRIBALYSE 3.2 for food products, DEFRA for UK-specific factors, and the INCI database for cosmetic ingredients. You do not manage any separate database contract, you do not renegotiate when adding a user, and you do not need to know which database version is current. The platform keeps everything up to date.

When you add up database licensing, expert time, and training, the real cost of running LCAs in openLCA for a typical consumer brand is often higher than a Devera subscription. Devera starts at 49 euros and tops out at 199 euros for 120 credits. For a product portfolio, the economics rarely favor the free option.

openLCA has no AI. There is no automated inventory builder, no gap filling for missing data, and no intelligent activity mapping. Everything is selected and entered by the user. This is by design. openLCA is a deterministic, transparent modeling environment where the user retains full control of every input. That is exactly what LCA consultants want.

Devera automates the steps that are repetitive and methodology-heavy while leaving decisions to the user. The AI proposes an inventory. It reads product data, identifies materials and packaging, maps them to Ecoinvent activities with confidence scores, fills gaps using a cascade of validated proxies, and flags anything it is uncertain about. The user reviews this proposal before finalizing.

This is the single biggest reason a product team would choose Devera over openLCA. The methodology guardrails, activity mapping, and proxy selection are the expert parts of an LCA. Devera does those parts automatically. openLCA expects you to do them.

openLCA is the right choice for academic research, for LCA consultancies that want an open and flexible modeling environment, for teaching and learning LCA methodology, and for any context where a dedicated practitioner is already in place.

Devera is the right choice for product teams at consumer brands, sustainability managers without an in-house LCA expert, and consultants who want to run more LCAs in less time. It is also a strong choice for any organization that wants published pricing, self-service access, and automation instead of manual modeling.
