SandBase Agent Runtime: A Local-First Runtime with Sandboxed Sessions

SandBase Harness is an open-source (Apache-2.0), local-first agent runtime that runs sessions, sandboxed tools, memory, credentials, and audit trails entirely on your own machine or infrastructure. It runs any model — OpenAI, Anthropic, DeepSeek V4, or any OpenAI-compatible endpoint — integrates MCP toolsets, and supports local process, Docker, Kubernetes, and self-hosted worker sandbox backends. In short, it turns a capable model into a production-grade, sandboxed, auditable agent without your data ever leaving your perimeter. ...

Daytona Review 2026: Sub-90ms AI Agent Code Execution Infrastructure

Daytona Review 2026: Sub-90ms AI Agent Code Execution Infrastructure

Daytona is an agent-native sandbox infrastructure platform that spins up isolated code execution environments in under 90ms — with optimized configurations hitting 27ms cold starts — eliminating the 2–5 second Docker delays that compound into 30+ second overhead across a typical 15-tool-call agent loop. What Is Daytona? Agent-Native Sandbox Infrastructure Explained Daytona is a managed sandbox platform purpose-built for AI agents — it provides isolated, stateful compute environments that agents can spin up, execute code in, snapshot, fork, and destroy without managing container lifecycle manually. Unlike generic cloud VMs or developer-oriented cloud IDEs, Daytona is engineered around the agent execution model: fast cold starts, persistent state between tool calls, and native SDK support for Python, TypeScript, Ruby, and Go. Founded in 2023 by Ivan Burazin, Vedran Jukic, and Goran Draganic — the team that built Codeanywhere, one of the earliest cloud development platforms — Daytona raised a $24M Series A in February 2026 led by FirstMark Capital, with Pace Capital, Upfront Ventures, Datadog, and Figma Ventures participating. Customers include LangChain, Turing, Writer, SambaNova, and Fortune 100 enterprises. The platform reached $1M forward revenue run rate in under three months after launch, then doubled that figure six weeks later — a trajectory that validates the market need for agent-native compute infrastructure beyond what general-purpose Docker-based tooling provides. ...
