Ecodesign & Digital Product Passport core
Product compliance registry · launching soon
The registrar for product compliance.
Listrar keeps one canonical record per product and resolves it three ways: a public passport page for people, a machine-readable feed for AI agents, and evidenced disclosures for regulators.

Two rails, one record
Humans get a page. Agents get a feed. Regulators get evidence.
A resolvable passport page
Every registered product resolves to a public Digital Product Passport page — server-rendered Schema.org JSON-LD, GS1 Digital Link compatible, with disclosure levels deciding who sees what.
An agent-readable feed
Listrar is the first DPP registrar designed to be read by AI agents: a machine-readable feed and an MCP server expose the same canonical record. No scraping, no PDFs.
Evidence, not adjectives
Every field carries provenance: its source, its verifier, its validity window. A claim is substantiated, or it is not published.
Regulation-driven schema
When the law adds a field, the registry adds a field.
Listrar's data model is built from the regulation down — encoded as attribute profiles that update without migrations or re-platforming. Digital Product Passport obligations phase in from 2026 through 2030; the registry moves when the delegated acts do.

How it works
Register once. Resolve everywhere.
01
Register
Create the canonical record: identity, composition, economic operators, claims.
02
Evidence
Attach provenance to every field — who stated it, who verified it, until when.
03
Resolve
Publish once. The passport resolves for consumers, agents, and authorities — each at their own disclosure level.
One registry, every actor
Built for the whole chain of responsibility.
Brands & manufacturers
Register products, orchestrate suppliers, publish passports that hold up.
Suppliers
Free, forever. Answer a data request once and reuse it across every customer.
Agencies & consultancies
Operate compliance for a portfolio of client brands from one place.
Verifiers & labs
Attach attestations directly to the records they certify.
Marketplaces & retailers
Check a product's compliance status before it goes on sale.
Institutional by design
A registry you can point a regulator at.
EU data residency
Registry data is stored and processed in the European Union.
Isolation by default
Every query is tenant-scoped and denied by default — enforced in the database, not just the application.
Evidence, not certification
Listrar evidences compliance; it does not grant it. No badges we can't substantiate — and none you can't either.
