JavaScript at C-speed. No cold starts. No billing shock.
DataVec is a cloud runtime for high-volume JavaScript backends. Write JavaScript, deploy normally, and DataVec compiles it into optimized C, keeps workloads resident in memory, and runs them on predictable flat-rate infrastructure.
Drop-in compatible with standard Web Workers, Next.js, and static site APIs. Built on native coroutine scheduling for massive vertical scaling.
Next.js Static Routing
Processes a complex nested endpoint router with custom JSON payload returns.

Compiling JavaScript into native C stateful coroutines yields direct machine execution speed.
A new execution model for JavaScript infrastructure.
DataVec keeps the developer experience familiar while compiling workers to C: supporting WebSockets, Postgres database connections inside isolated sandboxes, and deployments on dedicated VMs with integrated S3 object storage.
Compile at deploy time
The DataVec Builder converts JavaScript/TS Web Workers and WebSocket endpoints into optimized C before production traffic hits your VMs.
Stay resident in memory
The DataVec Runtime keeps workloads alive on leased VMs, eliminating the spin-up penalty and providing isolated sandboxes for database connections.
Charge by capacity
Choose the virtual server size and replica count. Traffic spikes do not automatically become surprise metered invoice surges.

Source-to-Native Translation Showcase
At deploy time, the DataVec Builder translates your standard JavaScript into idiomatic native C, mapping each construct onto hand-tuned native structures. Under the hood, this leverages our stackless coroutine framework to execute concurrent micro-threads in isolated, partitioned micro-heaps:

Virtualization Layer Comparison
Standard serverless architectures stack execution layers (virtual machines, JIT layers, and heavy JS engines) which adds CPU duration latency. DataVec compiles your service into a standalone, memory-protected virtual kernel daemon process.

Metered serverless vs. a flat DataVec bill
Configure your monthly footprint. We estimate the metered bill on your current serverless platform, then size the DataVec VM — and replica count — that serves the same peak load at our published per-core throughput, billed at one flat monthly price with no per-request metering.
Peak load ~3,472 req/s
Provisioned ~16,000 req/s

Illustrative estimate using vendors' published list prices as of June 2026 (AWS includes API Gateway; Cloudflare has zero egress). The DataVec figure is the real catalog price of the VM tier and replica count needed to serve your peak throughput — assuming a 12× peak-to-average burst — at our published single-core rates, with headroom and a 2-replica HA baseline. VM plans include generous egress — we don't meter bandwidth. At very high volume, metered platforms are often negotiated down with committed-use discounts, so compare against your actual invoice.
Every tier is a flat monthly price — from our Business plan at $75/mo down to a $10/mo Starter VM, with zero utility metering.
