Percona and MongoDB both land on Depends.

Percona

Depends

Confidence: Medium

Depends

Confidence: Medium

Buy MongoDB if you have developers and document-shaped, fast-changing, high-write data.

Percona versus MongoDB
Compare	Percona	MongoDB
Verdict	Depends	Depends
Best for	Teams running MySQL/Postgres/MongoDB at scale	Document-heavy, fast-changing schemas
Who it's not for	Small apps on managed cloud databases (RDS, Atlas)	Relational, join-heavy data . reviewers say Postgres wins
Privacy	Actively publishes advisories; 22 CVEs on record, including a critical PMM privilege escalation.^⁶	Active threat surface: critical 2025 memory-disclosure CVE reportedly exploited in the wild, plus a 2023 customer-data incident; patches released.
Support quality	Support is the core product; positive references	Trustpilot cites 'big company with 0 support'
Public sentiment	Public user feedback is thin but leans positive on expertise and PMM usability, with occasional pushback on choosing Percona over vanilla databases.^³	Users love the flexibility and quick start for document data, but commonly gripe about support, scaling costs, and default to Postgres for relational work.
Biggest gotcha	Everything beyond free software is quote-based; expect sales calls and opaque renewal costs.^⁴	MongoBleed (CVE-2025-14847): exposed or misconfigured instances were targeted; patch fast and audit exposure.
