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.

Open-source AI agent built in Rust — install, execute, edit, and test with any LLM

Goose is an open-source AI agent from Block (Square's parent company) that goes beyond code suggestions to actually execute tasks — installing dependencies, editing files, running tests, browsing the web, and calling APIs. Built in Rust for performance and portability, it runs locally on macOS, Linux, and Windows and is part of the Linux Foundation's Agentic AI Foundation. What sets Goose apart is its recipe system — portable YAML configs that capture entire multi-step workflows, shareable across teams and runnable in CI pipelines. Combined with MCP support for 70+ extensions (databases, GitHub, Google Drive, browser automation) and parallel subagents that can execute independent tasks simultaneously, Goose is closer to an autonomous engineer than a code assistant. With nearly 30,000 GitHub stars and growing, Goose is picking up adoption among developers who want a fully open, locally-run agent they can customize without giving a third party access to their codebase. The LLM-agnostic design means you can use Claude for complex reasoning, a fast local model for simple edits, and switch without reconfiguring the rest of your stack.
Reviewer scorecard
“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.”
“The recipe system is the sleeper feature here. Capture a workflow once, version it in git, run it in CI, share it with your team — that's how you scale agent-assisted development across an org. Goose is the first open-source agent I've seen that treats workflow portability as a first-class concern rather than an afterthought.”
“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.”
“Block is a payments company, not an AI lab, and enterprise AI agent projects from non-AI companies have a mixed track record for long-term maintenance. With 29K stars but fewer than 400 contributors, the community is still thin. There are more battle-tested alternatives like OpenCode for basic coding tasks.”
“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.”
“Goose being part of the Linux Foundation's Agentic AI Foundation is significant — it's a bet that agentic AI infrastructure should be community-governed, like Linux itself. If that model takes hold, Goose becomes foundational infrastructure in the same way git did. Block is making a real governance play here, not just a dev tool launch.”
“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.”
“The browser automation and Google Drive extensions through MCP mean Goose can handle the tedious content pipeline tasks — pulling briefs from Drive, opening staging sites, generating drafts — without any cloud-side integrations. For small creative teams that want agentic automation without handing their credentials to another SaaS, this is compelling.”
