Overview
Runs coding sessions in cloud sandboxes coordinated by a Cloudflare Workers control plane, driven from a web UI, Slack, GitHub PR comments, Linear issues or webhooks. Sessions use OpenCode or the Claude Agent harness with Anthropic, OpenAI, xAI, DeepSeek or Z.AI models, with multiplayer editing, commit attribution, child sessions and cron or event automations. For single-tenant engineering orgs.
Who it is for: Single-tenant engineering orgs running agents in cloud sandboxes
Strengths
- Snapshot restore, prebuilt images and proactive warming for fast session starts
- Automations from cron, Sentry alerts, GitHub workflow runs and inbound webhooks
- Secrets encrypted with AES-256-GCM and scoped globally, per repo or per environment
- Browser automation, code-server and a web terminal inside each sandbox
Weaknesses
- Single-tenant only; all users must be trusted members of one organization
- Control plane requires Cloudflare Workers, Durable Objects and D1
- Sandboxes run on third-party providers (Modal, Daytona, E2B, OpenComputer, Vercel)
- Cached credentials can persist in snapshots; grant removal does not revoke tokens
What it needs
- no GPU
- Compose
- Needs Cloudflare Workers, Durable Objects and D1, Sandbox provider (Modal, Daytona, E2B, OpenComputer or Vercel Sandbox), GitHub App, Slack and Linear apps (optional)
- Models: Anthropic Claude (API key or subscription), OpenAI Codex via ChatGPT subscription, xAI Grok via SuperGrok, OpenCode Zen and Go, Z.AI Coding Plan
