Coasts (Containerized Hosts for Agents) is an open-source infrastructure layer that solves one of the practical problems of running AI agents in production: safe, isolated execution environments. When an agent needs to browse the web, execute code, access files, or call external APIs, it needs a sandbox that prevents it from accidentally (or intentionally) doing damage to the host system or other agents. Coasts provides a lightweight, Docker-based hosting layer with per-agent isolation and configurable capability grants. The core abstraction is the "coast" — a container configuration that specifies exactly what an agent can and cannot access: which file paths are readable or writable, which network endpoints can be called, what CPU/memory limits apply, and how long the agent can run. Agents are spun up in these containers on demand and torn down after completion, providing strong isolation with minimal overhead. The configuration is declarative (YAML-based) and composable, making it easy to define agent capability profiles. With 98 points on Hacker News and 39 comments — one of the higher engagement rates in the agent infrastructure space — Coasts is hitting a real need. As more teams build agent pipelines in production, the question of "what happens when the agent does something unexpected" becomes critical. Container-based isolation is the proven answer from the broader DevOps world, and Coasts applies it specifically to the agentic AI context.
Reviewer scorecard
“Built-in database means zero external dependencies for simple CRUD apps. The automation engine is a nice bonus.”
“The declarative capability grants are exactly what I want — specify what an agent can touch and nothing more, spun up in a container with resource limits. This is the infrastructure pattern for production-safe agent deployment. YAML-based config means it slots naturally into existing IaC workflows.”
“For simple internal tools that need their own database, Budibase's self-contained approach is practical.”
“Container isolation is standard infrastructure work, and there are already several competing approaches (E2B, Modal, Daytona) with more polish and enterprise backing. Starting a new OSS project in this space faces real network effects headwinds. The real question is what Coasts offers that existing solutions don't.”
“The internal tools market is crowded. Budibase, Appsmith, ToolJet — differentiation is minimal.”
“The agent execution environment is going to become as important as the agent itself. As AI agents take real actions in the world — browsing, coding, executing — the infrastructure for capability isolation determines what's safe to automate. Coasts' open-source approach is important for avoiding vendor lock-in in this critical layer.”
“Deep DevOps infrastructure work — not relevant to creative workflows unless you're running a production AI system. The people who need this will know they need it; everyone else should wait for higher-level abstractions that hide the container complexity.”
