Blaxel
Perpetual sandbox platform — sandboxes that sleep but never die
Blaxel provides persistent sandboxes for AI agents that auto-suspend when idle and resume in ~25ms with full memory and filesystem state. Co-host agents, MCP servers, and batch jobs alongside sandboxes on the same backbone for near-zero latency. Supports 50K+ concurrent sandboxes, volumes for long-term file persistence, and enterprise-grade security with per-sandbox microVM isolation. Backed by Y Combinator.

Overview
When to use Blaxel
Blaxel is listed for Sandbox, Code Execution, Deployment workflows. Blaxel provides persistent sandboxes for AI agents that auto-suspend when idle and resume in ~25ms with full memory and filesystem state. Co-host agents, MCP servers, and batch jobs alongside sandboxes on the same backbone for near-zero latency. Supports 50K+ concurrent sandboxes, volumes for long-term file persistence, and enterprise-grade security with per-sandbox microVM isolation. Backed by Y Combinator. Consider it when an agent needs this capability through a documented service boundary instead of custom infrastructure maintained inside the application.
In 4agent's task model, the product maps to code execution, deployment, workflow automation. That makes it a candidate for workflows that build and deploy software, operate production agents, communicate with users, automate business workflows.
Integration checklist
- Access: confirm the api key authentication flow, credential scope, rotation process, and whether calls can be attributed to a user or service identity.
- Client support: official or documented clients are listed for typescript, python.
- Automation: OpenAPI is not currently recorded, MCP is listed as available, and CLI support is listed as available. Confirm each requirement in the provider's current documentation.
- Operations: test rate limits, timeouts, retry safety, error payloads, logs, data retention, and the current free-tier and paid pricing model with production-like volume.
