# CrowNest

Create isolated cloud sandboxes for AI agents. Run commands, stream logs, expose private previews, persist artifacts, and control usage with hard caps.

Agents can request public product pages with `Accept: text/markdown`, append `.md`, or use `/index.md` for index-style URLs.

- [Home](https://crownest.dev/): Cloud sandboxes for coding agents.
- [ai agent sandbox](https://crownest.dev/ai-agent-sandbox): Give AI agents an isolated cloud sandbox to run commands, install packages, and host previews. One SDK, CLI, and REST API, with per-second billing and hard caps.
- [code interpreter api](https://crownest.dev/code-interpreter-api): A code interpreter API for AI apps: execute Python and shell from your agent, stream stdout, capture results and artifacts, then tear down on a TTL. Metered per second.
- [cloud sandboxes](https://crownest.dev/cloud-sandboxes): What cloud sandboxes are and how they work — isolated Linux environments your code and agents control through an API to run commands and persist artifacts.
- [sandbox api](https://crownest.dev/sandbox-api): A REST and SDK sandbox API: create isolated environments, run and stream commands, manage files, expose authenticated previews, and collect artifacts. Idempotent and scoped.
- [e2b alternative](https://crownest.dev/e2b-alternative): Weighing an E2B alternative? Compare CrowNest cloud sandboxes for coding agents: SDK, CLI, REST API, authenticated previews, artifacts, and per-second billing. Date-stamped.
- [ai sandbox cost calculator](https://crownest.dev/ai-sandbox-cost-calculator): Estimate cloud sandbox costs for your AI agents. Set concurrency, runtime, and runs per day to see compute-hours and monthly spend at CrowNest's per-second rate.
