Recommendation

Decision note

Rebuilt from the original export under the complete V411 factual-source-verification workflow. Preview only. Apply remains blocked until Failures = 0, Warnings = 0, Unmapped = 0, Missing = 0; explicit clears are reviewed; image import is disabled or V380 accepts the asset; a representative WordPress edit screen is compared with the export and proposed row; and a post-Apply zero-change Preview succeeds.

Capabilities

Key features

Unified runtime interface for sandboxed shell execution

Local Docker and remote cloud backends

Modal and AWS Fargate optional support

Parallel environments for agent evaluation

Workflows

Use cases

Run coding agents against repositories

Create isolated test environments

Execute benchmark jobs in parallel

Develop custom remote runtime backends

Strengths

Pros

  • MIT-licensed and openly maintained
  • Local and cloud runtime choices
  • Designed for large parallel workloads
Considerations

Limitations

Agents can run destructive commands, expose secrets, or incur cloud cost when isolation is incomplete.

Use disposable environments, least privilege, network controls, quotas, audit logs, and human approval for sensitive operations.
