Sandock

What it does

Your coding agent needs a real filesystem — not a sandbox that forgets everything. Sandock gives it one: long-running Docker containers with SSD-backed persistent volumes and 100% POSIX compatibility. Run Claude Code, Codex, Anthropic Agent SDK, OpenClaw, Hermes, Pi Coding Agent, or your own agents directly — or embed them into your product. Terminal, browser, preview, git, and MCP workflows are built in, with pricing from $5/mo.

Nano Computers for AI Agents

Persistent cloud sandboxes with files, terminal, browser, preview URLs, and POSIX volumes — so coding agents can keep state, resume work, and evolve across tasks. Get started with 5 lines of code. JavaScript, TypeScript, and Python SDKs included 100% POSIX-compatible persistent storage. Full filesystem operations that coding agents like Claude Code depend on Whether you're building AI Agents, developing MCP Servers, or need a high-performance code execution environment with SSD-backed persistent storage, Sandock has you covered. Long-running Docker sandboxes with SSD-backed persistent volumes — coding agents like Claude Code, OpenAI Codex, and Anthropic Agent SDK work flawlessly with 100%…from sandock.ai

  ReplicasJun 2026 · replicas.dev · ▲239

  Hey HN! I'm Connor, creator of Replicas. I'm a heavy Codex/Claude Code user, and I wanted to hand off tasks to agents like I would to an engineer - kick something off before work, let it scaffold while I'm at lunch, even come back to a ready PR. The problem: existing alternatives use workspace VMs that are black boxes. I have no access to any of them - they can't run tests, read logs, or use tools like the Playwright MCP (which I use to verify agents actually fixed what they claim to fix). Replicas gives agents real cloud workspaces where they can: - Run your test suite and read the…

  Sandbox Agent SDK – unified API for automating coding agentsJan 2026 · github.com · ▲41

  We’ve been working with automating coding agents in sandboxes as of late. It’s bewildering how poorly standardized and difficult to use each agent varies between each other. We open-sourced the Sandbox Agent SDK based on tools we built internally to solve 3 problems: 1. Universal agent API: interact with any coding agent using the same API 2. Running agents inside the sandbox: Agent Sandbox provides a Rust binary that serves the universal agent API over HTTP, instead of having to futz with undocumented interfaces 3. Universal session schema: persisting sessions is always problematic, since…

  Hi HN, I’ve been working on PaperPod, an experiment in making compute native to AI agents. PaperPod is a sandbox runtime where coding agents like Claude Code can autonomously execute code, write files, run background processes, expose ports (preview URLs) etc. and pay per ms of usage via the agent native x402 payment protocol. No API keys or complex setup needed. This is early (alpha), but fully usable today with free compute included, no wallets needed, just use your email as X-User-Id in the request! A sample prompt to get started: To use PaperPod compute: 1. Get session: POST…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
