MongoDB Atlas vs Redis: pricing, quotas & features (2025)
Managed MongoDB with search, vector, stream processing
vs. The real-time data platform — in-memory DB + cache + vector + search
Data sourced from vendor documentation · Last updated May 2026
Summary
MongoDB Atlas and Redis are both dbaas platforms, addressing the same core use case with different implementation philosophies and trade-offs. Both offer a free tier, making it easy to prototype without a credit card. Redis's paid plans start at $5/month, lower than MongoDB Atlas's entry point at $8/month. Redis has a broader documented feature set (21 vs 14 features). Budget-sensitive teams will find Redis easier to justify early on.
