- Daytona T2
Daytona is secure, elastic sandbox infrastructure for running AI-generated code and agent workflows (isolated sandboxes with snapshots, volumes, computer use, MCP server). Pivoted from an open-source cloud development environment; as of June 2026 core development moved to a private codebase and the daytonaio/daytona repo was archived (2026-10-03). SDKs, API clients and CLI/MCP tools are published in the open daytona/clients repo. Founded by the ex-Codeanywhere team (Ivan Burazin).
- e2b T1
e2b provides secure, ephemeral sandboxes (Firecracker microVMs) for AI agent code execution. Each sandbox spins up in <200ms with full Linux environment, Python/Node/etc preinstalled. Substrate for code-agent products including Anthropic Claude Code (artifacts run on e2b), Perplexity, You.com Search, Cognition Devin (partially), and Hugging Face Spaces. Apache 2.0 OSS + managed cloud. $13M Seed + Series A 2024 (Sunflower Capital + a16z).
