Silos Edge Database · Postgres rolling out to 100+ regions

PostgreSQL at the edge.
Close to home, everywhere.

Built for low-latency reads with scale-to-zero economics — targeting sub-50 ms cold starts. Full PostgreSQL, materialized on demand in the region closest to your users.

Performance

Designed for edge latency.

Silos materializes a read replica close to where each request originates, so data lives near your users. Cold-start and latency figures below are design targets, not measured guarantees.

How it works Try the playground
How edge latency is achieved
Architecture, not benchmarks.
On-demand materialization
Replicas hydrate in the region closest to a request, then release resources when traffic subsides — so reads stay near the user.
WASM cold starts
The Postgres engine runs in a Wasmtime sandbox designed to spin up fast, targeting sub-50ms cold starts as the architecture matures.
Scale-to-zero compute
Idle databases consume no compute. A query brings the instance back; you're billed only for live work.
WAL streaming

Silos is designed to replicate changes from the primary to edge replicas by streaming the PostgreSQL Write-Ahead Log over NATS JetStream, with consistency tunable per query.

Scale

Built for massive scale.

Scale-to-zero economics with on-demand edge replicas. Pay only for what you use, and let dormant regions fall back to zero.

Explore regions See pricing
Multi-region replication
Replicas are designed to materialize on-demand at the edge closest to your users, then release resources when traffic subsides.
Scale to zero
Pay nothing when idle. A query arrives, the instance cold-starts, and you're billed only for live compute.
Usage-based pricing
Pay for compute time, storage, and data transfer — with no compute charge during idle periods.
Browser-native dev
Full PostgreSQL in your browser via PGLite. Prototype locally, deploy globally — same SQL, same extensions, zero setup.
Streaming-native
Built around the PostgreSQL Write-Ahead Log so changes propagate to replicas as they commit — designed for realtime, not polling.
On-demand materialization
Edge regions hydrate only when traffic appears, then release resources — no idle replicas to pay for.
The Silos Console

Watch replicas hydrate worldwide.

Write SQL, watch edge replicas materialize across the globe, and read live metrics — without leaving the browser. The same console your agents drive through the API.

Security

Enterprise-grade security.

Per-tenant WASM isolation, encryption at rest and in transit, encrypted snapshots, and comprehensive audit logging at every layer.

View security docs
WASM sandboxed isolation
Every tenant runs in its own WebAssembly sandbox — memory-safe, deterministic, with strict per-tenant isolation and per-query resource limits.
Encrypted everything
AES-256-GCM at rest and TLS 1.3 in transit. Encrypted WAL snapshots. Customer-managed keys planned for Enterprise.
Auth & audit
SCRAM-SHA-256 authentication, IP allowlisting, and audit logging across every layer. SOC 2 and HIPAA are on our roadmap.

Integrations

Works with your stack.

Silos speaks the PostgreSQL wire protocol, so standard Postgres drivers and ORMs connect the same way they would to any Postgres.

Prisma

Connects over the standard Postgres wire protocol — point Prisma at Silos like any Postgres.

Drizzle

Use the Postgres dialect you already know. Drizzle connects as it would to any Postgres.

Kysely

Type-safe SQL with Kysely's Postgres dialect over a standard connection.

Next.js

Use Silos from Server Components and route handlers with standard Postgres drivers.
