PubPeer

What PubPeer does

PubPeer operates a free, web-based post-publication peer review platform that enables researchers, academics, and scientists worldwide to search scientific publications by DOI, PubMed ID, or arXiv ID and leave comments discussing methodology, data integrity, reproducibility, and ethics. The platform serves the global scientific research community as a horizontal, persona-based segment: any verified first author of an indexed publication can create an account and contribute commentary, and the general public can read comments without authentication. PubPeer's commentary layer supplements confidential pre-publication journal peer review by providing a permanent, public, searchable record of post-publication critique. The service has accumulated a database of 258,080+ commented publications spanning high-impact journals (Nature, PNAS, Lancet, Cell, Science) and discipline-specific outlets.

The platform's technical architecture centers on a searchable scientific publication database with author email verification gating account creation. Complementary products include a Firefox browser plugin that overlays PubPeer comments on external journal websites, and dedicated Journals and Institutions Dashboards (dashboards.pubpeer.com) that let publishers and research institutions monitor commentary activity on their portfolios. No public API, SDK, or mobile applications are available; distribution is entirely through the website and browser extension.

PubPeer is operated by the PubPeer Foundation, a non-profit entity headquartered in San Francisco. The platform is entirely free to use with no subscription tiers, paid plans, or transaction fees, and the business model relies on donations and grants. Go-to-market is community-led: growth is driven by organic word-of-mouth adoption within the scientific research community rather than formal sales, marketing campaigns, or partnerships. The organization employs 1-10 people, has received no disclosed external funding rounds, and reports no revenue, grants, or management team details in publicly available data.

Core offering

PubPeer is a free, web-based post-publication peer review platform that hosts a searchable database of scientific publications.

The platform is operated by the PubPeer Foundation, a non-profit, and is supported by donations.

Product overview

PubPeer is a single unified product — an online journal club platform that provides a database of all scientific articles searchable by DOI, PubMed ID, or arXiv ID, with functionality for researchers to comment on publications and engage in post-publication peer review. The platform includes complementary tools: a browser plugin for viewing comments on external websites, and dashboards for journals and institutions to monitor publications.

Broad incumbents

• PubMed: PubMed is the canonical biomedical literature database indexed by DOI/PMID — the same identifiers PubPeer uses. It is a broad incumbent that could host or compete with post-publication commentary if it chose to extend its scope.
• bioRxiv / medRxiv: bioRxiv and medRxiv are preprint servers with large research audiences and comment functionality. They are comparable as platforms for scientific discourse around publications and could expand native commenting to compete with PubPeer.
• Academia.edu: Academia.edu is a broad academic sharing and discussion platform. It overlaps with PubPeer's mission of enabling public scholarly discourse around publications, though it focuses on sharing rather than critique.
• ResearchGate: ResearchGate is a large academic social network where researchers share, discuss, and critique publications. It serves the same audience and use cases (post-publication discussion of papers) as PubPeer at much larger scale.

Emerging players

• ORCID: ORCID provides verified researcher identifiers and is a non-profit. It is comparable to PubPeer in serving as non-commercial scholarly infrastructure that could integrate with or compete against identity-verified scientific commentary.
• F1000 (F1000Research): F1000Research pioneered open post-publication peer review with named reviewer reports. It is comparable as a platform that operationalized transparent, post-publication peer review — a direct adjacent model to PubPeer.
• SciPost: SciPost is an open peer-reviewed publishing platform with open review processes. It is comparable as a non-profit experimenting with openness in scientific publishing and review.

Direct peers

• Retraction Watch: Retraction Watch tracks retracted scientific papers and investigates research integrity issues. It is directly comparable to PubPeer as an independent, post-publication research-integrity platform serving the same scientific community.
• OpenReview: OpenReview is a direct peer — an open platform for scientific peer review and publishing run by the non-profit OpenReview Foundation. It overlaps directly with PubPeer in enabling open, public peer-review discourse around scientific papers.

Others

• Crossref: Crossref is the DOI registration agency underpinning scholarly publishing infrastructure. It is comparable as enabling/scholarly-infrastructure and could conceivably host integrity signals alongside DOIs that PubPeer currently aggregates.
