S3-Native Design
Everything you need for mission-critical applications
Hot data served from cache at <5ms, cold data from S3 at 80-200ms. Control your cache budget to optimize cost vs. performance for your workload.
Every write lands in S3 first. 99.999999999% durability guarantee with automatic replication across regions.
Object storage pricing with no per-read costs. Scale to billions of features without breaking the budget.
Handle billions of features with predictable performance. Add regions and capacity independently.
Sync updates across online and offline feature stores. One source of truth for training and serving.
Simple HTTP/REST API with SDKs for Python, Go, and Node.js. Integrate in minutes, not weeks.
Trusted by teams building at scale
Unified storage for training and inference features. Low-latency serving with historical consistency.
Cache model predictions at massive scale. Reduce GPU costs by up to 80% for repeated queries.
Store player progress and game state with low-latency access. Scale to millions of concurrent players.
Distribute configuration, routing rules, and metadata globally. Instant propagation without restarts.
Built for the object storage era
BoulderKV favors durability and cost efficiency over immediate read-your-writes consistency. Writes are durable immediately in S3, with eventual consistency to regional indexes (typically < 30s). Perfect for read-heavy workloads where strong consistency isn't required.
Built on principles that make sense for modern infrastructure
No surprise bills from read charges. Storage-based pricing that scales linearly with your data, not your traffic.
Up to 90% cost reduction compared to traditional KV stores. Perfect for read-heavy workloads that would break the bank elsewhere.
Pay for what you store and what you write. Read billions of records without worrying about usage spikes or throttling.
We're finalizing our pricing tiers to ensure they work perfectly for teams of all sizes. Early access customers will get special introductory rates and direct input on our pricing structure.
