Platform Comparison
Conferences.Center vs OpenReview
OpenReview is a free, nonprofit platform built around open, transparent peer review, and it is the standard for ICLR, NeurIPS and ACL Rolling Review. Conferences.Center is a commercial all-in-one: closed or blind review with enterprise access controls, research-integrity checking, publisher delivery, and the event side of a conference.
Comparison as of July 2026, based on publicly available information about OpenReview. Product capabilities and pricing change over time — verify current details with each vendor. Spot something out of date? Tell us and we’ll correct it.
The short version
OpenReview's defining idea is transparency: public submissions, public reviews and public rebuttal threads, backed by an open REST API and a nonprofit mission. For communities that have chosen open review as a matter of principle, that is exactly right, and this comparison is not an argument against it.
The differences are about scope and about access control. OpenReview is a review platform: it does not handle registration, scheduling, or proceedings delivery to IEEE, ACM or Springer. And where OpenReview optimises for openness, we optimise for controlled access — SSO, MFA, enforced tenant isolation and audit logging around a blind review process.
Confidentiality is worth naming directly because it is a live topic. In November 2025 the ICLR organisers reported that an unauthenticated API endpoint had exposed reviewer, area-chair and author identities for more than 10,000 submissions — roughly 45% of ICLR 2026 — and that some reviewers subsequently received score-manipulation demands. The incident was reported and addressed by the OpenReview team; we link the primary source rather than characterise it further.
Alongside that, published research has shown that LLM-generated reviews skew toward acceptance and that hidden prompt-injection text inside a submitted PDF can push an LLM-assisted reviewer toward accepting a paper. Our submission-integrity scanner exists specifically to surface that class of attack before a reviewer — human or model — opens the file.
Feature-by-feature comparison
Conferences.Center vs OpenReview across the workflows that matter for running a conference.
| Capability | Conferences.Center | OpenReview |
|---|---|---|
| AI-assisted conference setup | Yes — AI-assisted setup can draft tracks, timelines, and workflows from a brief or CFP for organizer review. | No — venue configuration is done through the API and OpenReview's own tooling. |
| Abstract & paper submission | Yes — CFP, abstracts, and full papers with multi-track submission and format checks. | Yes — submissions, revisions and public rebuttal threads. |
| Peer review (blind, COI, rebuttal) | Yes — single- and double-blind review, conflict-of-interest checks, and structured rebuttal periods. | Yes — open and transparent review, with a co-author/advisor graph used for conflict detection. Anonymity models are venue-configurable. |
| Reviewer matching / suggestions | Yes — reviewer suggestions from roles, tracks, and workload; organizers approve every assignment. | Yes — expertise-based affinity scoring plus reviewer bidding, represented as edges in its data model. |
| Ticketing & payments | Yes — built-in ticketing with Stripe-hosted payments where configured. | No — OpenReview does not handle registration or payments. |
| Live / hybrid event hub | Yes — live/hybrid hub with agenda, Q&A, polls, and attendee access for online and in-person formats. | No — no live or hybrid event tooling. |
| Attendee networking | Yes — attendee profiles, networking spaces, and meeting workflows, with assisted matching where configured. | No — public discussion forums rather than attendee networking. |
| Analytics | Yes — dashboards for submissions, reviews, registration, attendance, engagement, and revenue where configured. | Basic — review progress; not event analytics. |
| Data export & portability | Yes — structured exports across submissions, reviews, schedules, registrations, and attendees. | Yes — a documented open REST API and an official Python client, which is the most programmable export of any platform in this category. |
| Pricing model | Published per-event pricing from $290 for small events, with plans for larger or recurring conference programs. | Free — nonprofit, with the platform open-sourced under AGPL. |
| Best for | Teams that want submissions, peer review, scheduling, registration, attendee operations, and reporting in one platform. | Communities that have deliberately chosen open, public peer review — especially in machine learning. |
Where a cell says “varies by plan”, “add-on”, or “limited”, availability depends on the vendor’s tier or is not a core focus of that product.
Where OpenReview is strong
Genuinely free, nonprofit, and open source — with no commercial pressure on the review process.
The best programmatic access in the category: a documented REST API and an official Python client.
Open, public review and rebuttal threads that many ML communities consider a feature, not a trade-off.
Deep incumbency at ICLR, NeurIPS and ACL Rolling Review, so reviewers in those fields already know it.
Why teams choose Conferences.Center
One platform for peer review, ticketing, and the live event — instead of stitching several tools together.
Access control built for confidential review
SSO (OIDC/SAML), MFA, enforced tenant isolation and audit logging sit around the review workflow. If your venue runs blind review and reviewer confidentiality is a procurement question rather than a philosophical one, that posture is the difference.
Prompt-injection scanning before anyone reviews
Every submitted PDF can be scanned for hidden text and embedded instructions aimed at LLM-assisted reviewers — the attack class demonstrated in recent research. Results are advisory and go to a human chair; we never auto-reject a paper, and we do not claim to catch every possible technique.
Proceedings delivery to IEEE, ACM and Springer
Generate publisher-ready delivery packages — metadata, table of contents, copyright manifest, page-1 copyright-line stamping — plus ACM and Springer LNCS metadata and Crossref DOI deposit. OpenReview does not do publisher delivery.
The whole conference, not only the review
Registration, QR check-in, keynote-aware scheduling, sponsors and a live hub run in the same tenant as review, instead of bolting a second platform onto an open-review workflow.
Who should choose which
Choose OpenReview if…
Stay with OpenReview if open, public peer review is a deliberate commitment for your community, if you value a nonprofit AGPL platform, or if you need its open API and your venue is already established there.
Choose Conferences.Center if…
Choose Conferences.Center if you run blind review with confidentiality requirements, need integrity checking or publisher delivery, or want registration, scheduling and the live event handled in one place.
Frequently asked questions
What exactly happened in the OpenReview security incident?
In November 2025 the ICLR organisers published an incident report describing an unauthenticated API endpoint that exposed reviewer, area-chair and author identities for more than 10,000 submissions, roughly 45% of ICLR 2026, and noted that some reviewers then received score-manipulation demands. It was reported and addressed. We link the organisers' own report rather than restating it, and we do not suggest the issue is ongoing.
Is open review worse than blind review?
No — they are different models for different communities. Open review increases accountability and is a deliberate choice at venues like ICLR. Blind review protects reviewers from pressure. We support blind review with strong access controls; if your community has chosen open review on principle, OpenReview is built around that principle.
Can we migrate a venue from OpenReview?
OpenReview has a documented REST API and an official Python client, so a chair with credentials for their own venue can retrieve submissions, reviews and decisions programmatically. Note that its API has two generations and querying the wrong one silently returns nothing, so migrations should be done carefully. Our CMT importer ships today; OpenReview and EasyChair importers are on the roadmap and we will not claim them before they exist.
Do you use AI to write or score reviews?
No. Our AI features suggest reviewers, check citations, and flag integrity concerns — always advisory, with a human making every decision. We also let a venue record an AI-use policy, collect author disclosures, and capture reviewer attestations that they did not use an LLM to author a review or upload a manuscript to a third-party model.
