Now Generally Available

Simplify your infrastructure. Dramatically.

ShardMap eliminates the caching layer from your stack entirely. Your data stays local to each request, cutting latency by 100x and infrastructure costs to zero.

Distributed caches solved the wrong problem

When you went "stateless," you traded local memory for network calls. Every request now pays a tax—serialization, network round-trips, and operational complexity you never asked for.

✕ Before ShardMap

The hidden cost of "stateless"

Every user action triggers a round-trip to your cache cluster. It feels fast until you multiply it across millions of requests.

  • 1-2ms per cache call — Network latency adds up across your request lifecycle
  • CPU burned on serialization — Every object converted to JSON and back
  • Another system to monitor — Connection pools, eviction policies, failover
  • $2,000-20,000/month — For managed Redis alone
✓ With ShardMap

Data lives where it's used

Intelligent routing ensures requests land on the same server every time. Your cache is just local memory—no network required.

  • 0.05ms average — Memory access instead of network calls. 100x faster.
  • Zero serialization — Native objects in memory. No conversion overhead.
  • Nothing new to manage — Remove a service from your architecture entirely.
  • Infrastructure cost: $0 — Your existing servers handle everything.

Intelligent routing, not proxying

ShardMap doesn't sit in your traffic path. It tells your application exactly which server to connect to—then gets out of the way.

1

Your app asks "where?"

Before making a request, your client asks ShardMap which server owns that user's data. This lookup is cached locally and takes microseconds.

2

We calculate the optimal route

Using consistent hashing, we determine which server in your pool should handle this request—and provide a backup if unavailable.

3

Direct connection, warm cache

Your request goes directly to the right server. Because the same user always hits the same server, local memory serves as a perfectly warm cache.

Less infrastructure. Better performance.

The best system is the one you don't have to think about. ShardMap removes complexity while improving every metric that matters.

100x faster data access

Memory access in nanoseconds beats network calls in milliseconds. Your p99 latency drops dramatically.

🧹

Delete an entire service

No more Redis clusters to provision, monitor, or debug at 2am. One less thing in your architecture.

💰

Zero cache infrastructure cost

Stop paying for managed Redis. Stop paying for the engineer-hours to keep it running.

🔄

Graceful failure handling

When a server goes down, traffic automatically routes to the backup. No cache invalidation storms.

📦

Works with your stack

Simple HTTP API works with any language. Official SDKs for Node, Go, Python, and Rust.

📈

Scales without thought

Add servers to your pool and ShardMap rebalances automatically. Consistent hashing means minimal disruption.

We deleted our entire Redis cluster last month. Response times dropped from 45ms to 3ms, and our infrastructure bill is $8,000 lighter. I genuinely don't know why we didn't do this sooner.
