Blaxel is a perpetual sandbox platform built for AI agents. Our platform lets you keep infinite, secure sandboxes on automatic standby while co-hosting your agents for near instant latency.
Using Cursor, Claude Code, Codex, Goose, or another AI coding agent?Install the Blaxel skill to give your agent the ability to deploy AI agents, create sandboxes for code execution, host MCP servers, run batch jobs, and more…all using simple prompts, zero code required!
An AI agent is any application that leverages generative AI models to take autonomous actions in the real world. These agents often require computing power to execute their interactions. Some examples of agents include:
  • Conversational agents that are able to take action in the world while keeping a human in the loop for activation or validation: for example code generation agents with real-time previews.
  • AI-powered data pipelines: for example a data transformation pipeline that retrieves unstructured video files and uses an AI model to extract structured data then act on it.
  • RAG agents: for example, a chatbot assistant that can better answer consumers’ queries by autonomously running scripts to access relevant databases.
  • Autonomous system agents that handle machine-to-machine workflows: like a smart traffic monitoring system that analyzes video feeds, detects accidents in real-time, and automatically dispatches emergency services with AI-generated incident reports.
Blaxel’s infrastructure platform gives production-grade agents their own computing environments including code sandboxes, tool servers, and LLMs. It offers infrastructure to run these agents on a global network that makes them run fast and reliably. This website provides comprehensive documentation and API, SDK and CLI references to help you work with Blaxel.

Essential concepts

Blaxel is a perpetual sandbox platform designed for agentic AI. It doesn’t force you into any kind of workflow or shaped box. While we encourage you to exploit architecture designs that we consider are more reliable, our toolkit gives you all the pieces you need to build reliable agentic systems exactly the way you want. Blaxel consists of modular services that are engineered to work seamlessly together, but you can also just use any one of them independently. Think of it as a purpose-built set of building blocks that you can use to power agents.

The building blocks

At the heart of Blaxel is our flagship perpetual sandbox service. Sandboxes are secure, instant-launching compute environments that you can use for running AI code. Blaxel lets you keep sandboxes on automatic standby with optimized agent hosting for near instant latency. With Blaxel sandboxes, you get:
  • Automatic scale-to-zero after 5s inactivity, resume from standby under 25ms even after weeks.
  • microVMs with full access to file system, processes and logs — and native support for Zero Data Retention (ZDR).
  • Preview URLs with your own custom domain.
You can co-locate agent APIs, MCP servers, and batch tasks directly alongside your sandboxes to eliminate network hops and ensure the lowest possible end-to-end latency. For this, Blaxel also offers:
  • Agents Hosting - Deploy your AI agents as serverless auto-scalable endpoints. Completely framework agnostic: just bring your code, Blaxel builds it and runs it for you.
  • Batch Jobs - Scalable compute engine designed for agents to schedule and execute many AI processing tasks in parallel in the background.
  • MCP Servers Hosting - Deploy custom tool servers on a fast-starting infrastructure to extend your agents’ capabilities.
  • Model Gateway - Intelligent routing layer to LLM providers with built-in telemetry, token cost control, and fallback capabilities.
  • Full observability - out-of-the-box.

A cloud built for agents

Agents will transform how we work in the coming years. Traditional cloud providers weren’t designed to handle them and their one-size-fits-all architecture holds them back. We built Blaxel to fix that. Blaxel is a cloud where AI agents themselves are the primary users. All products are accessible through MCP servers, allowing agents to create and manage resources via tool calls. Blaxel provides agents with all the compute they need to scale and perform optimally: products like Sandboxes give them their own dedicated personal computer(s) / computing environments, while Batch Jobs enable them to schedule background tasks at scale. Building effectively on this cloud means embracing a few operational practices unique to how Blaxel works:
  • Blaxel sandboxes automatically scale up and down at near-instant speeds, unlike traditional sandbox providers. Let sandboxes suspend automatically when idle instead of deleting them. Resuming from standby is near-instant, even after long periods away. Learn more about the sandbox lifecycle, including session length and the standby-storage cost tradeoff in detail.
  • For guaranteed long-term data persistence beyond a sandbox’s own lifecycle, use Volumes or Agent Drive. If you persist data this way, you can delete the sandbox itself; to resume, re-create the sandbox (~2–4 seconds) and restart processes to restore state.
  • TTLs and lifecycle policies let you automatically clean up sandboxes you no longer need.
  • When you delete a sandbox, all data is immediately erased. If the sandbox was never put into standby mode, Blaxel guarantees ZDR (zero data retention).
  • Break down and distribute your agents whenever possible. A single monolithic agent handling all tool calls, LLM calls, and task workflows can be deployed to Blaxel Agents Hosting - but it will be harder to maintain, monitor, and will use resources inefficiently. Blaxel SDKs allow builders to split services and connect them from your code.
  • Similarly, while direct tool calls are possible, deploying separate MCP servers improves reusability, optimizes resources, and simplifies monitoring. Blaxel also optimizes placement globally when your serverless tool server needs to make multiple backend calls.

Which component should I use?

When building your agentic system, you’ll need to make architecture design choices. Blaxel offers several high-performance compute options, summarized below in order of latency performance, alongside two storage products (Volumes and Agent Drive) for long-term persistence:
  • Sandboxes: Perfect for maximum workload flexibility. These microVMs provide full access to filesystem, network, and processes, booting from standby in under 25ms.
  • Agents Hosting (sync mode): Ideal for running HTTP API services that process requests within a few seconds.
  • Agents Hosting (async mode): Best for running HTTP API services handling longer requests without maintaining an open connection.
  • Batch Jobs: Designed for asynchronous tasks that may run for extended periods where boot latency is less critical. These jobs are triggered by providing specific input parameters, unlike Agents that are a fully hosted API.

Volumes and Agent Drive are storage products, so “boot time” and “workload duration” don’t apply.

The Blaxel powerhouse

Blaxel is a fully managed cloud platform. For regulated or enterprise customers who require “self-hosted” options: private network connectivity and bring-your-own-server arrangements are available; contact us to discuss your requirements. When you deploy workloads to Blaxel, they run on a technical backbone called the Global Agentics Network. Its natively serverless architecture automatically scales computing resources without any server management on your part. Global Agentics Network serves as the powerhouse for the entire Blaxel platform, from Agents Hosting to Sandboxes. It is natively distributed in order to optimize for low-latency or other strategies. It allows for multi-region deployment, enabling AI workloads (such as an AI agent processing inference requests) to run across multiple geographic areas or cloud providers. This is accomplished by decoupling this execution layer from a data layer made of a smart distributed network that federates all those execution locations. Finally, the platform implements advanced security measures, including fine-grained authentication and authorization through Blaxel IAM, ensuring that your AI infrastructure remains protected. It can be interacted with through various methods, including APIs, CLI, web console, and MCP servers.
