Best Daytona alternatives
The strongest Daytona alternatives are E2B, Fly.io Sprites, Modal Sandboxes. Pick based on what you need that Daytona does not offer — see the reasons under each entry.
Why teams look beyond Daytona
The strongest choice for stateful coding-agent workspaces and breadth of sandbox types; note the shift away from open source.
- No longer actively open source — the public repo is archived
- Default Linux sandboxes use container isolation; VM isolation requires VM sandboxes
- Fork and pause/resume limited to VM sandboxes
Daytona alternatives, ranked
E2B
Open-source cloud sandboxes for AI agents, each a Firecracker microVM, with pause/resume, snapshots and forking.
- Firecracker microVM
- Open source
- Self-hostable
- BYOC
- Pause/resume
Why it’s here: Code interpreters and short-to-medium-lived agent tasks that need microVM isolation, with an open-source self-host path. The safe default for most agent builders: mature, open source, microVM-isolated and widely supported.
Fly.io Sprites
Persistent, hardware-isolated Linux computers for AI agents with a durable 100 GB disk, checkpoints, and no compute charges while idle.
- MicroVM
- Pause/resume
Why it’s here: Long-running, stateful agent computers that should cost nothing while idle. The most natural “persistent computer per agent” model, with idle-free billing.
Modal Sandboxes
Sandboxes on Modal’s serverless compute platform for running untrusted code at very high scale, with GPUs, snapshots and tunnels.
- gVisor or VM
- GPU
- Pause/resume
Why it’s here: High-concurrency and GPU-backed sandboxes — RL rollouts, evals and coding agents at scale. The best fit when scale or GPUs matter most, especially for teams already on Modal.
Vercel Sandbox
Firecracker microVM sandboxes on Vercel’s infrastructure, persistent by default and billed on active CPU, with fine-grained egress control.
- Firecracker microVM
- Pause/resume
Why it’s here: Teams on Vercel and agent builders who want microVM isolation, active-CPU billing and credential brokering. A polished microVM sandbox with standout egress and billing design; the obvious pick for Vercel-centric teams.
Together Code Sandbox
Together AI’s microVM sandbox service, built on the CodeSandbox acquisition, with snapshot-based starts, hibernation, cloning and preview URLs.
- MicroVM
- Pause/resume
Why it’s here: AI app builders and coding products that need hibernatable, forkable dev-environment VMs with preview URLs. Battle-tested microVM dev environments, now best suited to teams already working with Together AI.
Northflank Sandboxes
Sandboxes on Northflank’s Kubernetes-based platform — microVMs for CPU work, gVisor for GPUs — on Northflank’s cloud or in your own cloud account.
- Cloud Hypervisor microVM
- BYOC
- GPU
- Pause/resume
Why it’s here: Teams that want sandboxes in their own cloud account (BYOC) alongside app hosting, databases and GPUs. Compelling for BYOC and all-in-one platform needs; review the October 2026 incident response before adopting.
