Both platforms are trusted by clinical research organizations worldwide. This guide compares them feature-by-feature to help you choose the right EDC for your study programme, without excessive sales pressure or marketing noise.
A snapshot of where the two platforms differ most for clinical research teams.
| Feature | Castor EDC | Veeva Vault EDC |
|---|---|---|
| Best for | Academic, emerging biopharma, MDR/PMCF, speed | Mid-large pharma, Veeva ecosystem, eTMF/CTMS |
| Deployment | SaaS, cloud-native | SaaS, cloud-native |
| Study builder | No-code, visual | Modern, some configuration needed |
| eCOA | Integrated | Native (Veeva eCOA, in Vault Clinical) |
| eConsent | Integrated | Dedicated module |
| RTSM | Native randomization (variable block, stratification, blinding). Trial supply via partner | Native (Veeva RTSM) |
| RWE/Registry | Integrated module | Limited |
| Ecosystem | Standalone or light integrations | Strong Vault suite integration |
| Implementation | 3-4 wks low-complexity / standard, 4-8 managed (8-12 high), vs a 10-14 wk legacy average | Months, often consultant-led |
| Pricing model | Predictable flat-rate study licensing, no per-subject fees | Pricing not publicly disclosed |
| MDR/PMCF support | Purpose-built | Not primary focus |
Feature-by-feature analysis with a clear advantage call for each area.
| Feature | Castor EDC | Veeva Vault EDC | Advantage |
|---|---|---|---|
| Cloud-native SaaS | Yes, architecture-first | Yes, modern platform | Tie |
| No-code eCRF builder | Yes, visual drag-and-drop | Yes, but more configuration | ✓ Castor |
| Integrated eCOA | Yes, mature module | Native (maturing) | Comparable |
| Integrated eConsent | Yes, unified platform | Dedicated module, maturing | Tie |
| RTSM | Native randomization (trial supply via partner) | Yes (Veeva RTSM) | Comparable |
| EU MDR/PMCF support | Purpose-built | General compliance | ✓ Castor |
| Decentralized trial (DCT) support | Yes, strong | Yes, growing | Tie |
| Vault ecosystem integration | Light (no lock-in) | Deep (eTMF, CTMS, eConsent) | Veeva |
| Implementation speed | 3-4 wks low-complexity / standard, 4-8 managed (8-12 high), vs a 10-14 wk legacy average | Months | ✓ Castor |
| Pricing transparency | Predictable flat-rate study licensing, no per-subject fees | Pricing not publicly disclosed | Comparable |
| Standalone value | High (no suite needed) | Better with full Vault suite | ✓ Castor |
An honest look at what each platform does well, and where it has trade-offs.
Castor EDC is a cloud-native, Amsterdam-based platform trusted in 160+ countries (cumulative, to date). Its core strength is speed and simplicity: no coding required, no consultants needed, transparent per-study pricing. The platform combines EDC, eCOA, eConsent, native randomization, and RWE modules into one system.
Strengths
Limitations
Veeva Vault EDC is part of the Veeva Vault Clinical Suite, positioned as a modern alternative to legacy platforms. It excels when used alongside other Vault products (eTMF, CTMS, eConsent). Enterprise clients often adopt Veeva for ecosystem integration and regulatory content management.

Common questions from teams evaluating Castor and Veeva Vault EDC.
Castor and Veeva do not have native, deep integrations. You can export data from Castor and import into Veeva systems, but this is manual or custom-built. If Veeva ecosystem integration is critical to your operations, Veeva Vault EDC is the better choice.
Castor uses transparent per-study pricing based on study scope. Veeva uses enterprise contract models with negotiated pricing based on multi-year commitments and total suite use. Castor is typically easier to budget for. Veeva can offer economies of scale for large organizations running many studies across a full Vault suite.
Both platforms support decentralized and hybrid trials. Castor has strong native eCOA and eConsent for remote patients. Veeva offers similar capabilities through its dedicated modules. For purely DCT-focused programmes, either platform works. Your choice depends on other factors such as pricing model, ecosystem integration, and team familiarity.
Technically yes, but Veeva’s full value is unlocked when paired with eTMF and CTMS. Castor, by contrast, delivers full functionality including EDC, eCOA, eConsent, and native randomization without requiring additional modules or platform investments.
