Fastest filesystem in any sandbox

Our sandboxes have file systems which are close to SSDs in performance. This enables agnets to process data and compile code faster

Runs ON OUR CLOUD AND IN VPCs

The data plane can be deployed in VPCs. Data doesn't leave your network. You use your own reserved instances and pricing.

100K+ concurrent sandboxes

We have designed a state of the art cluster scheduler to enable users to run upward of 100k+ sandboxes in parallel.

Multi-cloud fleet

Sandboxes spread across AWS, GCP, Azure, or bare metal automatically. We ensure the CPU family of your sandbox is consistent so there is no variation in performance.

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.

AGENT HARNESS EXECUTION ENVIRONMENT

Execution Environment for Agents & Tools

Run agent harnesses, code interpreters, browser helpers, and tool-calling agents inside isolated, stateful sandboxes — each with its own filesystem, shell, packages, and processes. Keep the agent in the sandbox for long-running sessions, or spin up separate sandboxes only when a tool needs risky or heavy execution.

ingredients
Isolated runtime per sandbox

No shared state. No interference. Each agent runs in it's 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.

Other Sandbox Patterns

Infrastructure for RL Environments

Run real-world environments inside sandboxes. Execute systemd, Docker, browsers or any Linux software. Clone environments, run them in parallel, and scale to 100k+ concurrent sandboxes.

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.

SECURITY

Sandboxes Powered by
a state-of-the-art Scheduler

We built a scehduler from the ground up to spin up 100 sandboxes/second on a single host and can bring up 1000s of sandboxes/second on large clusters in parallel. This is 10-17x higher than Kubernetes.

Copy-on-write Memory

The scheduler uses a copy-on-write memory to keep cluster state in memroy for low latency scheduling

Multi-Tenant and Dedicated Clusters

The scheduler understands tenancy of workloads and can schedule workloads on both dedicated and shared clusters.

Event Driven

The scheduler is fully event driven to respond to cluster topology changes faster or to allocate a new sandbox request.

Multi-Driver Dataplane

We use Firecracker MicroVM and CloudHypervisor depending on the workload and hardware resource asks of sandboxes.

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

Tensorlake data plane can deploy in 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.
