# bestcloudagents

> bestcloudagents.com helps engineering teams choose a cloud coding agent. It compares Replicas, Devin, Cursor, Claude Code, Codex and OpenCode on published criteria (multi-harness support, isolated cloud VMs, pull-request output, Slack/Linear/GitHub/GitLab triggers, bring-your-own model keys, usage-based pricing, SOC 2, SCIM, audit logs, self-hosting, parallel and scheduled runs) and ranks them for a team's answers in an interactive chooser.

bestcloudagents.com is operated by Replicas (replicas.dev), one of the platforms compared. The criteria, weights and every product's answers are published on the methodology page, and the chooser recommends another product when a team's answers point to one.

## Main pages

- [Home](https://bestcloudagents.com/): overview, recommendation and when it changes
- [Chooser](https://bestcloudagents.com/chooser): ten questions; every product scored with reasons
- [Full comparison](https://bestcloudagents.com/compare): every product on every criterion, with sources
- [How we score](https://bestcloudagents.com/methodology): criteria, weights, formula, sources and disclosure

- [How to run Claude Code in the cloud (and keep it running when your laptop sleeps)](https://bestcloudagents.com/blog/run-claude-code-in-the-cloud): Four ways to run Claude Code in the cloud, from Anthropic's own Claude Code on the web to a rented VM, GitHub Actions and Replicas, with what each needs and costs.
- [Why your team needs a multi-harness cloud coding agent platform](https://bestcloudagents.com/blog/multi-harness-cloud-coding-agent-platform): What a multi-harness platform is, why the agent is becoming a commodity while the environment is not, and what to check before you commit to one agent's cloud.
- [Isolated VM environments for cloud coding agents, explained](https://bestcloudagents.com/blog/isolated-vm-environments-for-cloud-coding-agents): Why cloud coding agents should get a fresh, isolated VM per task, how that compares with containers and shared machines, and what a good agent environment includes.

## Products covered

- Replicas (Replicas Group Inc., https://replicas.dev): A cloud coding-agent platform that runs Claude Code, Codex, Cursor, OpenCode, Pi and Muse Code in isolated cloud VMs, started from Slack, Linear, GitHub, GitLab or the dashboard, and hands back pull requests.
- Devin (Cognition, https://devin.ai): Cognition's autonomous software engineer: its own agent, cloud sessions in a VM, an editor (Devin Desktop, formerly Windsurf), a CLI and a codebase wiki.
- Cursor (Anysphere, https://cursor.com): An AI code editor whose Cloud Agents run the Cursor agent in isolated cloud VMs and return pull requests, started from the editor, the web, Slack, Linear, GitHub or the API.
- Claude Code (Anthropic, https://code.claude.com): Anthropic's coding agent: a terminal CLI and IDE extensions, plus Claude Code on the web, which runs sessions in an Anthropic-managed VM.
- Codex (OpenAI, https://chatgpt.com/codex): OpenAI's coding agent: an open-source CLI, IDE extension and SDK, plus Codex cloud, which runs tasks in OpenAI-hosted environments from ChatGPT.
- OpenCode (OpenCode (open source), https://opencode.ai): An MIT-licensed terminal coding agent that works with 75+ model providers and local models. Run it yourself on a laptop, a server or CI.
