Blaxel

Blaxel is infrastructure for autonomous agents, centered on isolated microVM sandboxes, persistent shared storage, and programmable networking. It helps teams run agents, jobs, and MCP servers with fast resumes and state that can survive across sessions.

Infrastructure for autonomous agents

Blaxel is infrastructure for autonomous agents: isolated microVM sandboxes, persistent storage, and programmable networking designed to let agents run, connect, and operate without rebuilding the surrounding runtime. The platform centers on short resume times, stateful execution, and built-in primitives for compute, storage, and network control.

The product line includes Sandboxes for persistent compute, Agent Drive for shared filesystem access, batch jobs for fan-out workloads, and MCP hosting for running tool servers on the same private network. The site positions these pieces as a single foundation for agentic workloads that need isolation, shared context, and repeatable execution.

Core capabilities

Isolated sandbox compute

Run agents, apps, or jobs in individual microVMs that boot in milliseconds and resume from standby in about 25ms with memory and filesystem state intact.

Persistent storage and shared memory

Attach state that survives restarts, resumes, redeploys, and collaboration, including shared files and durable volumes for longer retention.

Shared filesystem for agents

Use Agent Drive as a distributed filesystem that multiple sandboxes can read and write concurrently, with POSIX-compliant access through a FUSE client.

Programmable networking

Control egress, inject secrets, pin static IPs, and route model calls through a private network backbone.

Jobs and MCP hosting

Run thousands of isolated tasks with batch jobs, or host MCP servers as first-class workloads on the same private network as agents.

Usage-based scale-up

Start free with usage-based pricing, then scale through quota tiers or move to custom deployments for dedicated locations, private connectivity, and invoice-based billing.

Practical use cases

Long-running agent sessions
Run an agent in a persistent sandbox when it needs to keep files, process state, and logs across repeated interactions instead of starting from scratch each time.
Multi-agent collaboration
Mount Agent Drive into multiple sandboxes so several agents can share notes, artifacts, datasets, or dependencies while working on the same task set.
Parallel task execution
Fan out work with batch jobs when you need many isolated tasks to run at once and then aggregate their outputs on shared storage.
Private tool execution
Host MCP servers alongside agents on the same private network when tool calls should stay within Blaxel rather than going out to external infrastructure.
Controlled network access
Use programmable networking to shape outbound access, route model calls, and expose sandboxes with controlled IPs or injected secrets.

Pros and Cons

Pros

Isolated microVMs provide strong workload separation for agents and jobs.
Sandboxes resume in about 25ms and keep memory and filesystem state intact.
Shared storage options support both concurrent collaboration and longer-term retention.
Programmable networking gives control over egress, secrets, static IPs, and model routing.
Pricing is usage-based with a free start and custom deployment options for larger needs.

Cons

Agent Drive is shown as a private preview, so it may not be generally available yet.
Agent Runtime is marked coming soon on the pricing page, so the platform is still expanding some runtime options.
Several performance and scale claims are presented on marketing pages and are not independently verified in the source.

FAQ

What does Blaxel do?

Blaxel provides isolated microVM sandboxes, persistent shared storage, and programmable networking for autonomous agents. The source also describes batch jobs and MCP server hosting on the same platform.

How is Blaxel priced?

The pricing page says Blaxel is usage-based with no base subscription. It offers a free start with up to $200 in credits, then credit-based pay-as-you-go pricing, plus custom deployments for dedicated needs.

What developers can use Blaxel with?

The site says Blaxel supports TypeScript-first SDK usage, with Python at parity, and includes Docker images, MCP servers, and storage built in. The sandbox page also shows a basic TypeScript example.

What is Agent Drive?

Agent Drive is described as a distributed filesystem for AI agents that can be mounted into any sandbox for concurrent, POSIX-compliant access.

How do Blaxel sandboxes handle state and resuming?

The site says sandboxes boot in milliseconds, resume in about 25ms, and keep memory and filesystem state intact. Idle sandboxes auto-suspend, and the page says they can persist across sessions.
