Sandboxes
for Agents

Stateful Execution Environments
for Agents

Today's infrastructure was built for running web applications. Agents are different, they run longer, call more tools, and need stateful environments to store context and memory. Tensorlake Sandboxes are stateful VMs with sub-second startup and restore, live migration across machines, and auto suspend-and-resume. Your agents keep working no matter what.

Spins up in milliseconds, restores in under a second
Live migration: sandboxes move to healthy machines automatically, no work lost
Auto suspend after inactivity, serverless boot on first request
2x faster filesystem than Vercel, 5x faster than E2B
Scale to 100s of sandboxes per second, millions concurrently

Key features
Isolated execution

Every agent session runs in its own sandbox with a full filesystem. LLM-generated code can't touch your infrastructure or leak data to other sessions.

Instant scale

Spin up 100 sandboxes per second with no cold starts. Handles bursty agent workloads without queuing, throttling, or manual provisioning.

Serverless BOOT

Sandboxes boot up instantly when applications running inside them are called

BREAKDOWN
Full filesystem per session

Each sandbox gets its own isolated filesystem. Agents can read, write, and execute files freely without any risk of cross-session contamination.

Persistent Memory and File Systems

Snapshot file system and memory of sandboxes to be able to clone them across the cluster or resume them from the point they were suspended

Sandbox States

A sandbox can move through these lifecycle states:
breakdown
1.
Pending

Sandbox is being scheduled or started.

2.
Running

Sandbox is active and ready for commands or file/process operations.

3.
Snapshotting

The sandbox is creating a filesystem snapshot.

4.
Suspending

The sandbox is being suspended and snapshotted for later resume.

5.
Suspended

The sandbox has been suspended and can be resumed.

6.
Terminated

Sandbox has been stopped manually or due to a timeout.

Do more with Code Sandboxes

REAL VM ISOLATION

Each sandbox runs in a Firecracker microVM. LLM-generated code can't touch your host.

APPLICATION ENDPOINTS

Expose applications in sandboxes as stable HTTP endpoints.

Serverless boot

Sandboxes boot up immediately when Application Endpoints are hit

CLONE SANDBOXES

Clone a running sandbox in real time to 100s of other instances

VERSION SANDBOXES

Take point in time snapshots to restore sandboxes to a specific point in time.

RUNs ANYWHERE

Run sandboxes in your VPC or in Tensoralke Cloud

What agents can build with sandboxes:

FINANCIAL DATA ANALYSIS

Agent pulls live data, writes and runs analysis code in a sandbox, returns structured insights.

WEB RESEARCH AGENT

Agent spawns a headless browser, navigates to sources, scrapes and summarizes, all sandboxed.

CODE EXECUTION PIPELINE

Agent writes transformation code, executes it against a dataset, returns clean output. No infra needed.
