Move agent workloads into secure, stateful environments that wait on standby indefinitely, resume in under 25ms, and preserve complete filesystem and memory state.

Teams building with Blaxel
CodeSandbox alternative
Compare the production requirements that matter for agent workloads: resume latency, state continuity, isolation, and runtime control.
Resume from standby
CodeSandbox SDK
Restore a hibernated microVM in about 500ms.
Blaxel Sandbox
Resume in under 25ms with complete filesystem and memory state restored.
Standby lifecycle
CodeSandbox SDK
Keep hibernated sandboxes on disk for up to 7 days. CodeSandbox may archive them sooner if disk space is limited.
Blaxel Sandbox
Keep the sandbox on standby indefinitely without compute charges while idle.
Isolation
CodeSandbox SDK
Run untrusted code in isolated microVMs.
Blaxel Sandbox
Run each sandbox in a microVM with hardware-enforced tenant boundaries.
Production controls
CodeSandbox SDK
Manage sandboxes through the SDK with environment variables and private previews.
Blaxel Sandbox
Apply domain policies, inject secrets at the proxy, use dedicated egress IPs where configured, and inspect the runtime live.
Run a persistent agent sandbox on Blaxel.

From prototype to production
Resume the same environment, attach access policy, inspect work in progress, and choose where the workload runs.
Persistent runtime state
A sandbox can remain on standby indefinitely. Its filesystem, memory, and running processes return in under 25ms when the workload reconnects.
Policy-bound networking
Restrict outbound domains, inject secrets at the proxy, and use dedicated egress IPs.
Runtime inspection
Stream stdout and stderr, watch process and filesystem events, and open a private preview when a human needs to review the result.
Deployment control
Keep the framework and model provider that fit your product. Build custom images from Dockerfiles, run on Blaxel's managed platform, connect through VPC peering, or discuss deployment in your own cloud.
Keep the agent code
Migration involves refactoring infrastructure code rather than rewriting agent logic. Connect the agent to Blaxel through the REST API or SDK.
SDK integration
Keep OpenAI agent logic while moving code execution, files, streaming, and previews into a persistent Blaxel sandbox.
Built-in MCP tools
Keep Claude Agent SDK or Claude Code while moving filesystem, process, and code-generation work into an isolated Blaxel computer.
Move one CodeSandbox workload to Blaxel.

CodeSandbox migration
Use Blaxel when an agent workload moves into production and needs persistent state, fast resume from standby, isolated code execution, and runtime controls. CodeSandbox remains a fit for prototyping agent features during early development.
A Blaxel sandbox can remain on standby indefinitely without compute charges while idle. Its filesystem, memory, and running processes remain available when the workload reconnects.
A Blaxel sandbox resumes in under 25ms with its filesystem and memory state restored. The agent can continue in the same environment without rebuilding it between runs.
Each Blaxel sandbox runs inside a microVM with hardware-enforced tenant boundaries. Teams can also restrict outbound domains and inject secrets at the proxy instead of placing credentials inside the sandbox.
Migration changes the infrastructure integration, not the agent's core logic. Move environment variables and secrets into Blaxel's controls, then connect the agent to its sandbox through the REST API or SDK.
From prototype to production
Create a workspace and run one real agent workload with persistent state, secure isolation, and instant availability.
