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.
Compiled & resident
Compiling JavaScript into native C stateful coroutines yields direct machine execution speed.
No cold start · no interpreter · no GC pauses
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.

Compiled to C. Caged by the kernel. Blind to your secrets.
The first question about compiling JavaScript to C is “how is that secure?” — but the thing protecting you was never the language. It’s the cage around it. On DataVec that cage is kernel-enforced and tighter than the V8 process you run today: your Worker can’t make a syscall it wasn’t granted, and your secrets never enter it at all. Compiling to C confines your code harder than the runtime you came from, not less.
Your Worker can’t make a syscall it wasn’t granted
Every Worker runs under Syscall User Dispatch with a narrow, kernel-enforced allow-list. Try to open a file, spawn a process, or dial a socket it wasn’t granted and the kernel traps it and reaps the process — there’s no library policy to bypass.
Least privilege at the OS
Each Worker is pledged to a minimal set of operations and unveiled to only the exact paths it needs. Its filesystem and capability surface is cut to near-zero before a line of your code runs — OpenBSD-grade confinement, per request.
Your secrets never enter your code
Database passwords, API keys, and per-upstream tokens live in the host. It attaches them to requests on your Worker’s behalf — your JavaScript never holds a secret it could log, exfiltrate, or redirect to another host. A compromised Worker can’t leak what it never sees.
Capabilities are off until granted
SQL, object storage, email, outbound fetch, and AI streaming are denied by default and enabled per service. Least privilege is the default, not an opt-in. Revoke a capability and the Worker’s await fail-closes instantly — no redeploy.
Hard process isolation, no shared state
One isolated OS process per request over a bounded memory region — no cross-tenant heap, no shared globals. A crash or a compromise is contained to a single process and reaped, never spreading across your traffic.
You never hand-write the C
The JS→C lowering is content-addressed, API-grounded, and behaviorally gated — a faithful, tested lowering of your JavaScript over bounded region allocation, not arbitrary C. You get C’s speed without ever touching C’s manual-memory footguns.

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.

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.
