Daytona
Choose when agents need sticky filesystems and full dev environments. E2B for disposable code exec. Confirm licensing after 2026 closed-source shift. Strengths: Persistent coding environments for agents; OSS + cloud; Fast workspace spin-up.
Strengths
- Persistent coding environments for agents
- OSS + cloud
- Fast workspace spin-up
Weaknesses
- Container isolation ≠ Firecracker
- Positioning overlaps E2B/Modal
- Ecosystem still scaling
Fly Machines
DIY sandbox substrate with global edge. Prefer E2B unless you need custom machine control. Strengths: Programmable VMs globally; Firecracker isolation; Integrate with Fly networking.
Strengths
- Programmable VMs globally
- Firecracker isolation
- Integrate with Fly networking
Weaknesses
- You build more sandbox UX yourself
- Not agent-specialized like E2B
- Ops knowledge required
