SAAS AS A TABLE

Every business system,
as just another SQL table.

Interact with your CRM, ERP, and payment tools as if they were just another table in your database. Stacksync mirrors your SaaS data into Postgres or Snowflake in real-time, allowing you to read and write data using standard SQL. Say goodbye to rate limits and complex API documentation.

See how it works
  1. 01 Mirror CRM, ERP and payment data into Postgres or Snowflake in real time
  2. 02 Read and write through standard SQL — no custom API integrations
  3. 03 No rate limits and no API docs — just the tables you already know

ELASTIC COMPUTE

Scale compute on demand,
without the downtime.

Match capacity to your real workload instead of your worst-case guess. Resize vCPUs and memory on the fly, auto-scale through traffic spikes, and scale compute independently from storage — so you never pay for headroom you aren't using or hit a ceiling when demand surges.

See how it works
  1. 01 Resize vCPUs and memory in seconds — no migrations, no maintenance windows
  2. 02 Auto-scale to absorb traffic spikes, then scale back down to control cost
  3. 03 Compute and storage scale independently, so you never over-provision either

VIRTUAL NETWORKING

Private by default,
isolated by design.

Every database runs inside its own virtual network, never exposed to the public internet unless you choose to. Connect privately to the systems you already run, segment access down to the rule, and keep traffic encrypted end to end — security your compliance team can actually sign off on.

Explore networking
  1. 01 Each database runs in an isolated VPC — no public internet exposure by default
  2. 02 Connect privately over VPC peering or PrivateLink to your existing infrastructure
  3. 03 Lock down access with security groups, IP allowlists, and encrypted transit

BLOCK STORAGE

Durable, high-throughput storage
that grows with you.

NVMe-backed volumes deliver the low-latency IOPS your heaviest queries need, while storage expands automatically as your data grows — no manual provisioning, no surprise full disks. Continuous snapshots and replication keep every byte recoverable, so a bad deploy is a rollback, not an incident.

See the architecture
  1. 01 NVMe-backed volumes deliver low-latency IOPS for your most demanding queries
  2. 02 Storage expands automatically as your data grows — no manual provisioning
  3. 03 Continuous snapshots and replication keep every byte durable and recoverable
