Cloud dev environments & sandboxes, in detail
Disposable, reproducible environments in the cloud — for humans, and increasingly for AI agents. No category shifted harder in 2024–2025: Gitpod became Ona and went enterprise, Daytona pivoted to agent sandboxes, and per-hour billing became the norm. Know which product a vendor is actually selling before you standardize.
| Tool | Free tier | Entry price | Billing unit | Watch out for | Best for |
|---|---|---|---|---|---|
| GitHub Codespaces | 120 core-hrs + 15 GB-mo (personal) | ~$0.18/hr (2-core) | Per core-hour + storage | Free allowance applies to personal accounts, not orgs | Zero-setup dev box on any GitHub repo |
| Coder | Full OSS (AGPL), unlimited | Premium: quote | Self-hosted; your infra | You operate it — Terraform templates, upgrades, capacity | CDEs inside your own cloud/VPC; regulated orgs |
| Buddy Sandboxes | 300 CPU-min + 730 GB-h/mo | Bundled (Pro €29/mo) | CPU-minutes + GB-hours | Staging-VM shape (endpoints, snapshots) more than an IDE-in-browser | Per-branch/PR staging VMs with public HTTP/TCP endpoints |
| Ona (ex-Gitpod) | None meaningful | Sales-led | Enterprise contract | Rebranded from Gitpod ~Sept 2025; Classic free tier retired | Enterprise envs + coding agents in your VPC |
| Google Cloud Workstations | None (generic GCP credit) | ~$0.20/hr mgmt + compute | Per workstation-hour | Costs stack: management fee plus the underlying VM | GCP shops needing IAM-controlled in-VPC dev envs |
| Daytona | Starter credits | Usage-based per-second | Per vCPU/GiB-second | Pivoted (~Feb 2025) from human dev envs to AI-agent sandboxes | Running untrusted AI-generated code in isolation |
| Replit | Limited free workspace | Core ~$25/mo | Flat plan + AI usage | Pricing now centers on AI agent usage, not plain IDE seats | Instant browser IDE + hosting for small projects |

Notes & recent changes
- Gitpod deprecated its Classic product (with the 50 h/mo free tier) through 2025 and relaunched as Ona — budget for an enterprise conversation, not a credit card signup.
- Daytona's original open-source dev-environment manager is deprioritized; the product now sells per-second sandboxes for AI agents.
- Codespaces pricing has been stable since 2022 GA: ~$0.18/hr for 2-core plus $0.07/GB-month storage.
Which one should you pick?
- You just want a dev box on a GitHub repo → Codespaces.
- Compliance says environments stay in your cloud → Coder (or Cloud Workstations on GCP).
- You need per-PR staging with real endpoints, not an IDE → Buddy Sandboxes.
- You're sandboxing AI-agent code → Daytona.
