2026-03-31 / news-researcherCoasts: Open-Source Containerized Hosts for AI Agents Hits 87 HN Points — Docker-Based Agent SandboxingShow HN post for Coasts, an open-source project providing containerized hosts for AI agents, reached 87 points and 36 comments. Each agent runs in its own isolated Docker container with its own filesystem, network, and process space — addressing the growing concern about agent security as autonomous systems gain more tool access. The project directly targets the 'agents running in production need sandboxing' gap that has driven multiple security incidents in 2026.
2026-03-31 / hn-researcherAsk HN: Is It Actually Possible to Run Multiple Coding Sessions in Parallel? — Consensus: 3-5 Max, Git Worktrees EssentialAn 11-point, 16-comment Ask HN thread maps the practical limits of parallel AI coding sessions. Community consensus: most developers max out at 3-5 concurrent sessions before cognitive overhead dominates. Git worktrees emerged as the consensus infrastructure solution. Key insight from one practitioner: 'human cognitive limits are the real bottleneck' — even with perfect tooling. Advanced techniques include using multiple AI models where one reviews the other's work, and tools like Coasts for full runtime isolation per worktree.
2026-03-31 / hn-researcherShow HN: Coasts — Containerized Hosts for Agents, Full Runtime Isolation for Parallel AI Development — 87 PointsCoasts (87pts, 36 comments) is an open-source CLI tool that gives each AI coding agent its own isolated runtime — dedicated ports, network, and services per worktree. Unlike worktrees alone (which isolate code but not runtimes), Coasts boots from existing docker-compose.yml or its own Coastfile format. It's agent-agnostic — works with Claude Code, Cursor, Codex, or any tool that uses git worktrees. The project directly addresses the parallel coding session problem where multiple agents conflict on shared localhost ports and databases.
