What you would be giving up
Castor EDC is most often brought in for an academic hospital running an investigator-initiated trial that cannot fund a sponsor-grade edc contract or a data management cro, a medical device company collecting post-market clinical follow-up data with part 11 audit trails, a multi-site registry that needs remote econsent because participants are recruited nationally rather than at a clinic, a biotech running a small phase two study that wants the database built by its own clinical team in weeks rather than commissioned. Anything replacing it has to cover the ones you actually depend on, and a cheaper tool that misses one of them is not cheaper.
Two things this page cannot settle. It compares on price, model, tier count and rating, because those are the fields the category listing carries, feature-level differences need both full records, which is what the head-to-head pages load. And the ratings are third-party aggregates imported with each entry rather than reviews written here, so a 0.2 difference between two tools is noise rather than a finding.
If Castor EDC is broadly right and the question is cost, the Castor EDC pricing breakdown covers every tier and what each one adds. If you want the whole field rather than a shortlist, the Research category lists everything the directory holds, and best research tools ranks them.
Castor EDC runs on web, ios, android. Platform coverage is not carried on the category listing for the alternatives, so it is one more thing to check on each head-to-head page rather than here.
