Comparison, updated August 2026
# Looking for an OpenEvidence alternative in the EU?
OpenEvidence geoblocked the European Union and United Kingdom in April 2026, and European clinicians who used it daily lost access overnight. CliniAtlas was built for European practice from the start: hosted in the EU, grounded in EMA and European guideline sources, free for verified clinicians, with a citation on every line. This page is a direct comparison so you can decide quickly whether it fits your practice. One thing up front: CliniAtlas is our product, and we are not affiliated with OpenEvidence.

## CliniAtlas vs OpenEvidence at a glance

** **: **CliniAtlas**: **OpenEvidence**:

**EU and UK availability**: Available. Built and operated in the EU. | Unavailable in the EU and UK since April 2026; no public re-entry announcement found as of 5 August 2026.

**Hosting and data processing**: Application and stored service data in AWS eu-central-1. AI processing may occur outside the EU through global AWS Bedrock routing. Evidence searches also call external source services. | US-based provider. Public privacy materials describe processing across multiple locations and do not promise EU-only data residency.

**Sources**: PubMed, Europe PMC, EMA labels and assessment reports, and European clinical guidelines. | Peer-reviewed literature from 300+ journals, plus FDA, CDC, NEJM, JAMA, and US specialty-society content.

**Citations**: A citation on every line. Sources are inspectable and graded by their place in the evidence hierarchy. | Cited answers with source links.

**Price**: Free for verified healthcare professionals and students. | Free for verified US clinicians, ad-supported.

**Clinician verification**: European HCP verification. No US NPI number required. | Current mobile listing requires an NPI; the product page describes access for verified US HCPs.

**Accuracy evaluation**: Public evaluation methodology; the first clinician-reviewed baseline results are still being finalized. | Evaluated in peer-reviewed and preprint studies; its architecture, base models, and training pipeline remain proprietary.

**Product focus**: European HCP workflows; English and Croatian app interface, with English and German public content. | US HCP workflows; current public product materials emphasize US clinicians and US regulatory and specialty sources.

The short version: if you practise in Europe, the practical question is not which tool is better in the abstract, but which tool you can use at all, where your queries are processed, and whether it knows the sources your regulator and your guidelines actually cite. Those are the axes this comparison is built on.

## What European clinicians should check before adopting any evidence tool
Where are the core service and model inference hosted, and which external services receive search terms? Which sources does the product read, and do they include EMA labels and European guidelines alongside a US-focused source mix? Can I inspect the citation behind every claim? And what public evaluation exists, with how much methodological transparency? Tools differ far more on these questions than on their chat interfaces. Our answers are on the methodology page (https://cliniatlas.com/methodology/) and the EU evidence search overview (https://cliniatlas.com/eu-evidence-search/).

## Not just us: the other alternatives
CliniAtlas is not the only option for European clinicians, and depending on your country, language, and institution another tool may fit better. We maintain an honest ranked comparison of eight OpenEvidence alternatives for European clinicians (https://cliniatlas.com/guides/best-openevidence-alternatives-europe/), including tools we compete with. Practising in the UK? There is a UK-specific comparison (https://cliniatlas.com/compare/openevidence-alternative-uk/) as well.

## Frequently asked questions

**Is there an OpenEvidence alternative available in the EU?**
Yes. CliniAtlas is an EU-hosted clinical evidence search platform that is available across the EU and UK, free for verified healthcare professionals and students. Several other tools also serve European clinicians; see our full comparison of eight alternatives.

**Why did OpenEvidence leave Europe?**
OpenEvidence withdrew access for EU and UK users in April 2026, citing regulatory uncertainty around the EU AI Act. There is no announced timeline for a return.

**Is CliniAtlas free like OpenEvidence was?**
Yes. CliniAtlas is free for verified healthcare professionals and students, without advertising.

**How is CliniAtlas different from OpenEvidence?**
CliniAtlas hosts its application and stored service data in the EU. AI processing may occur outside the EU through global AWS Bedrock routing; evidence-search terms also reach external source services. It explicitly retrieves European regulatory and guideline sources such as EMA labels alongside PubMed and Europe PMC, and it publishes the methodology used to evaluate answer quality.

**Is CliniAtlas a clinical decision-support system?**
No. CliniAtlas is a professional reference and evidence-retrieval tool for general clinical and scientific questions. It does not diagnose, recommend treatment for an individual patient, or function as a certified clinical decision-support system.
