Running in sandboxed VMs with full development environments, Inspect integrates with their entire tooling stack (Sentry, Datadog, GitHub, Slack) and supports multiple frontier models. The system achieves ~30% of all merged pull requests through fast session startup, unlimited concurrency, and multiplayer collaboration. The article provides a detailed technical specification for replicating their architecture, covering execution environments using Modal sandboxes, OpenCode agent integration, Cloudflare Durable Objects for state management, and client implementations including Slack bots, web interfaces, and Chrome extensions for visual React editing. ## Full article daily.dev links to this article rather than hosting it.
