The honest brief
E2B
Firecracker microVM isolation with stateful sessions — code interpreter pattern where vars persist across agent turns.
- Firecracker microVM hardware isolation
- Stateful sessions across agent turns
- Sub-second cold starts
- Large catalog of community templates
- Open-source SDK
- No native GPU sandboxes (vs Modal)
- Daytona quotes faster cold starts
- Per-second billing adds up at scale
- Narrower than full infra platforms
Freestyle
Pairs fast Linux VMs with API-first Git an agent can commit to directly — a run-and-version layer purpose-built for AI-written code, not human devs.
- Micro-VMs boot in under 600ms
- Live forking and pause/resume
- GitHub sync built in
- Open-source tooling (Adorable, CLI)
- Core VM/Git cloud is proprietary SaaS
- Centered on TypeScript/JS stacks
- Early-stage company (founded 2024)
