## At a glance

- **Tool**: smolvm
- **Company**: smol machines
- **Category**: [Developer Productivity & Workflow](https://ai.dosa.dev/category/productivity)
- **Pricing model**: Open Source
- **Official website**: https://github.com/smol-machines/smolvm

## Key features

- Sub-second microVM boot times and elastic memory allocation
- Branchable VMs using copy-on-write snapshots for rapid state replication
- Hardware-isolated environments with granular network and credential control
- Portable.smolmachine artifacts for consistent local and cloud execution
- Integrated GPU support for CUDA and Vulkan workloads

## Pricing

**Model**: Open Source

The smolvm CLI and engine are free and open-source. The company also offers a managed service, smol cloud, which uses usage-based pricing for compute, memory, and disk resources.

## Who it is for

- **Best for**: Running isolated coding agent sandboxes, untrusted code, and persistent local development environments that require a real Linux kernel boundary.
- **Not ideal for**: Applications requiring traditional Docker container behavior without the overhead of a dedicated guest kernel or those needing workloads that bypass hardware isolation.

## Verdict

smolvm is a high-performance, developer-focused tool that effectively bridges the gap between local sandboxing and managed cloud execution through a consistent API.

## Recent updates

The latest version, v1.32.4, released on 2026-10-28, includes updates to DMA-BUF heap exposure for Android, improvements to private registry credential seeding, dependency updates for security, and refinements to CI processes.
