Free tier	32 GiB maximum per project, and at most 10 unpublished projects per user. Both are config knobs (process.max_upload_size, services.upload_limit) rather than business limits, and they differ per deployment. Publishing requires at least one successfully parsed entry, and publishing is what frees the 10-project slot. unit GiB; metered on unstated
Price	none stated
Identity	email email
Egress	Free and anonymous for published entries via the NOMAD API and GUI.
Per-object cap	not stated
Retention	not stated
Interface	rest rest
Tooling	Parsers are plugin-based, so what counts as a valid file is deployment-specific.
Composes with	10 unpublished projects × 32 GiB = 320 GiB of live scratch on a free account, and publishing an entry releases a slot. So the steady-state ceiling is bounded by how fast a human can publish, not by bytes.
Reliability	Well-run EU (FAIRmat) infrastructure with a real API. The constraint is semantic, not technical.
Parsed numbers	has-free-tier 1
