Fastest filesystem in any sandbox

Compile code, run databases, process 5GB files. Real-time cloning to fork a sandbox into multiple copies all the same state.

Runs in your VPC

The data plane deploys directly in your cloud. Data doesn't leave your network. You use your own reserved instances and pricing.

100K+ concurrent sandboxes

Spin up 200 sandboxes per second. Run 100K at once. Cold start under a second.

Multi-cloud fleet

Sandboxes spread across AWS, GCP, Hetzner, or bare metal automatically. Consistent CPU bundles across the fleet so RL training runs don't get variance from mismatched hardware.

Stateful sandboxes

Full state preserved on suspension or crash. Resume where you left off, debug what happened, or fork into a new sandbox. Auto-suspend watches memory access so you only pay when something is actually running.

Agent Harnesses

Sandboxes for Running Agent Harnesses

Run the agent itself inside an isolated, stateful computer instead of on the app server. This is the sandbox mode for browsing agents, research harnesses, and long-running sessions that need files, bash, packages, and working state.

ingredients
Isolated runtime for the harness

Give the agent its own filesystem, shell, packages, and processes instead of sharing the app server runtime.

Stateful by default

Sandbox sleeps on inactivity, wakes instantly when invoked

Built for long-running sessions

Near-SSD speed in a VM, 2x faster than Vercel, 5x faster than E2B

Tools

Isolated Execution Environments for Running Tools

Keep the agent harness outside the sandbox and create isolated sandboxes only when a tool needs risky or heavy execution. This is the pattern for code interpreters, browser helpers, and tool-calling agents that should not run untrusted code inside the harness itself.

ingredients
Run LLM-generated code away from the harness

Execute code, browsers, or system tasks in a separate sandbox so the main agent never shares its runtime.

Control the network per sandbox

Predictable throughput means fresh sessions spin up immediately, even when a thousand others are mid-task.

Size sandboxes dynamically at runtime

Run generated code safely. LLMs write code to compute answers, transform data, query databases. Every session gets its own sandbox so untrusted code can't touch system integrity or leak data across sessions.

Agents

Execution Environments for Agents

Run agent harnesses and tool calls in isolated environments, each with it's own file system, shell and packages. The sandbox infrastructure provides consistent median and p99 latencies to enable good user experience.

ingredients
Isolated runtime per sandbox

No shared state. No interference. Each agent runs in its own environment.

Stateful by default

Predictable throughput means fresh sessions spin up immediately, even when a thousand others are mid-task.

Built for long-running sessions

Run generated code safely. LLMs write code to compute answers, transform data, query databases. Every session gets its own sandbox so untrusted code can't touch system integrity or leak data across sessions.

Dynamic resource control

Predictable throughput means fresh sessions spin up immediately, even when a thousand others are mid-task.

RL Infra Infrastructure

Infrastructure for RL Environments

Execute systemd, docker, browsers or any linux software in sandboxes. Sandboxes can be cloned with an API call to replicate the exact state for faster rollouts.

ingredients
Prepare once, clone many

Snapshot an environment and fan it out instantly.

Known starting state

Predictable throughput means fresh sessions spin up immediately, even when a thousand others are mid-task.

Scale rollouts and evals

Run generated code safely. LLMs write code to compute answers, transform data, query databases. Every session gets its own sandbox so untrusted code can't touch system integrity or leak data across sessions.

Dynamic Resource  Allocation

Predictable throughput means fresh sessions spin up immediately, even when a thousand others are mid-task.

SCALE

Cluster Scheduler Designed for Sandbox Orchestration

We built a state of the art cluster scheduler designed to handle high throughput sandbox creation at scale with consistent latency

Copy-on-write scheduling

A copy on write state machine in the scheduler enables low latency placement decisions for millions of sandboxes in minutes

Oversubscription on Dedicated Clusters

The scheduler enables oversubscribing resources so you can pack more sandboxes on dedicated clusters

Dyanmic Resource Allocation

Sandboxes are allocated resources dynamically without incurring scheduling overhead

Heteregenous Isolation Guarantees

The dataplane of the scheduler uses a driver interface to enable resource isolation using Firecracker and CloudHypervisor based on workload charactaristics

Other Sandbox Patterns

Infrastructure for RL Environments

PREPARE ONCE, CLONE MANY

Snapshot a prepared environment and reuse it across workers.

KNOWN STARTING STATE

Keep files, packages, processes, and seeds consistent across runs.

SCALE ROLLOUTS AND EVALS

Snapshot a prepared environment and reuse it across workers.

DYNAMIC RESOURCE ALLOCATION

Choose the CPU, memory, GPU, and image each environment needs.

Benchmark setup: 2 vCPU / ~4 GB sandboxes, 3 runs.

Built for workloads that hit disks

In our published SQLite benchmark across Tensorlake, Vercel, E2B, Daytona, and Modal, Tensorlake was the fastest across default, fsync, and large-dataset runs.

FOR TEAMS OUTGROWING SAAS

Bring Tensorlake Into Your Cloud

BYOC is scale and control

Run sandboxes and applications in your own cloud or private environment when you need lower egress, stricter network boundaries, dedicated capacity, or more predictable performance.

Security and network boundaries

Keep code and data inside your preferred cloud boundary when shared SaaS deployment is no longer acceptable.

Performance and latency control

Keep compute closer to your data and tighten the runtime behavior for latency-sensitive agent workloads.

Cost and reserved capacity

Move from usage-based hosted infrastructure to capacity you can plan, reserve, and operate more predictably.

ORCHESTRATION

Sandbox-Native Orchestration for Agents

Once sandbox usage turns into a real application, Orchestrate is the layer that coordinates it. This is where you add application endpoints, durability, fan-out, retries, and application-level observability on top of sandbox execution.

ingredients
Application endpoints

Expose sandbox-backed workflows as callable applications instead of stitching together raw VM APIs.

Distributed fan-out

Predictable throughput means fresh sessions spin up immediately, even when a thousand others are mid-task.

Wake on request

Run generated code safely. LLMs write code to compute answers, transform data, query databases. Every session gets its own sandbox so untrusted code can't touch system integrity or leak data across sessions.

Application observability

Run generated code safely. LLMs write code to compute answers, transform data, query databases. Every session gets its own sandbox so untrusted code can't touch system integrity or leak data across sessions.

Queues, timers, and retries

Run generated code safely. LLMs write code to compute answers, transform data, query databases. Every session gets its own sandbox so untrusted code can't touch system integrity or leak data across sessions.
