Start free. Scale to petabytes. Every edition includes all eight data models, full SQL, and ACID guarantees.
Every committed transaction in Maree-DB is anchored to a cryptographic integrity chain, signed by the server's Ed25519 key. This means tampering with historical data is mathematically detectable — the integrity check fails. Included in Professional and above. Required for SOC 2 Type II, ISO 27001, and government deployments.
The "per processor" price is just the entry fee. Here is what a 16-core production server actually costs across one year and five years.

*Prices from publicly available vendor price lists as of 2026. Actual negotiated prices vary. Calculated as: Oracle DB EE $47,500/proc + RAC $23,000/proc + Partitioning $11,500/proc + Advanced Security $11,500/proc = $93,500/proc × 8 procs (16-core) = $748,000 + 22% annual support = $912,560 Year 1. Five-year total includes cumulative support on growing licence base.
$1.5 million vs $30,000 for the same capabilities — plus autonomous ransomware detection, post-quantum cryptography, Byzantine fault tolerant clustering, and five wire protocols that the legacy vendor doesn't offer at any price.
