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)
