Daytona

Infrastructure
high confidence
www.daytona.io ↗ · Status: active confirmed · Founded 2023

Daytona provides secure, elastic, programmatic sandboxes (Linux containers, Linux and Windows VMs, and GPU sandboxes) that AI agents spin up in under ~90ms (vendor claim) to run untrusted AI-generated code in isolated, stateful runtimes with snapshot and fork primitives. It is a managed service with a Bring-Your-Own-Compute option and has been closed source since June 2026. It is an integrated sandbox provider for Anthropic Claude Managed Agents, OpenAI Agents SDK Sandbox Agents and Cognition Devin Outposts, and targets code execution, computer use and RL/eval rollouts.

What practitioners should know

For researchers

  • The fork and snapshot API (since Apr 2026) branches full sandbox state (filesystem, databases, services), which is useful for tree search and RL rollouts. Daytona's own Terminal-Bench study found full snapshots mattered on a stateful task (4/5 vs 0/5) but independent retries did better on file-centric tasks (17/25 vs 6/25).
  • Harbor, the official Terminal-Bench 2.0 harness, supports Daytona as an execution environment through --env daytona for high-concurrency runs.
  • Computer-use evaluation: Daytona published a reproducible OSWorld Windows run (46 tasks), and Yutori's n2 playground runs OSWorld-image Linux desktops on Daytona with noVNC.
  • The platform code is no longer open source, so reproducibility depends on the hosted service or Bring Your Own Compute. The archived AGPL repo is unsupported.

For program managers

  • Frontier-lab ties are platform integrations, not disclosed customer contracts. Daytona is a sandbox provider for Anthropic Claude Managed Agents and for OpenAI Agents SDK Sandbox Agents. It is also a Cognition Devin Outposts partner.
  • Scale signal: $48.3M of equity sold (Form D, Aug 2026; $60M offering) about six months after the $24M Series A. Stage, lead investor and valuation are undisclosed. Hiring is focused on GPU and Windows sandbox teams.
  • Strategy shift: closed source since June 2026, citing security. The legacy AGPL repo is archived and unmaintained.
  • Customer references beyond Clay (verified) are mostly vendor-published: LangChain, Turing, Writer, SambaNova, the Cursor integration, Yutori, Anchor and Brainbase.

For data ops

  • SDKs in Python, TypeScript, Go, Ruby and Java. Integrations include the openai-agents[daytona] extra, a Claude Managed Agents guide, Devin Outposts, Cursor Self-Hosted Pools, Harbor/Terminal-Bench, and Stripe Projects provisioning.
  • trust.daytona.io lists SOC 2 Type II (Insight Assurance, issued 2026-07-28), SOC 2 Type I, HIPAA, ISO/IEC 27001 and GDPR. Reports are available on request, and all are vendor-hosted.
  • Security history: an April 2026 advisory on API credentials readable inside sandboxes with sudo was fixed on 2026-04-09; rotate keys if you used affected snapshots before then. The CVE-2026-31431 ('Copy Fail') kernel flaw was patched fleet-wide within 12 hours, with no customer action required.
  • Breaking API change: sandbox listing moved to cursor-based pagination, and the old endpoint and page parameter stopped working on 2026-06-25 (SDK v0.180.0 or later required). Org webhooks and OpenTelemetry org metrics are available.
  • Bring Your Own Compute: customer-run runners in custom regions under Daytona's control plane, deployed with official Helm charts.

Benchmarks & research

2 published
In-house research blog study, not peer-reviewed, by Daytona ML Researcher Daniel Thi Graviet. It compares independent retries with branching from full sandbox snapshots on five Terminal-Bench tasks plus a custom stateful SQLite task.
Five Terminal-Bench tasks: independent retry 17/25 vs snapshot branching 6/25. Stateful staged-service-repair task: full snapshot 4/5 vs 0/5 for clean restart and git-diff restore.
Vendor-run evaluation on Daytona's blog, not peer-reviewed. It runs 46 OSWorld Windows tasks (Excel, Word, PowerPoint and multi-app) on Daytona Windows sandboxes and provides a reproducible fork.
Claude Opus 4.6 averaged 31.54% vs GPT-5.4 at 29.13% (Excel 45.45% vs 27.27%; Word 33.12% vs 55.34%). Sandbox created in 10.5s; desktop ready in about 32s.

Buyer analysis

Best fit: Buyers needing fast, isolated, programmatic sandboxes to safely execute AI-generated code or run agent tool/computer-use loops at scale.

How we verified this

2026-10-05 refresh: I opened every source in the draft. The core facts held up. The SEC Form D confirms $48,274,000 of equity sold in a $60M offering (filed 2026-08-17, first sale 2026-07-31, 6 investors, Rule 506(b)). The closed-source announcement (2026-06-11), the GitHub archive (2026-10-03, about 71.7k stars), the Trust Center SOC 2 Type II details, the changelog versions and dates, the research posts and the Cursor and Yutori posts all match what the draft says. I also confirmed the three founder headshots: each framerusercontent.com image sits directly beside the matching name card on daytona.io/about, returns a valid PNG, and shows a single-person headshot. The main corrections: (1) the 'Series B' label rests only on one aggregator, because AlleyWatch gives no stage and the Form D says only 'Equity', so the stage is now undisclosed; (2) the April 2026 OpenAI Agents SDK date was sourced to an Upstash article that does not support it, so I replaced it with OpenAI's own v0.14.0 release (2026-04-15), which names Daytona among seven hosted sandbox providers; (3) I removed the claim that BYOC is invite-only and experimental, which the current docs do not support; (4) I removed an unsupported Eclipse Theia/VS Code detail from the CTO's background; (5) I re-dated the security advisory to its 2026-04-13 publication and fixed its category. I added in-window items the researcher missed: the Cognition Devin Outposts partnership (corroborated on Cognition's docs), the Stripe Projects, Anchor Browser and Brainbase integrations, a vendor-run OSWorld Windows evaluation, and a Kubernetes startup-time study. I hit the web-search budget limit during verification, so the hunt for missed items covered Daytona's blog index and primary partner docs, not a broad press sweep. A press release naming the new round's lead investor could therefore exist and not have been found.
