    Introducing Moltworker: a self-hosted personal AI agent, minus the minis

    Moltworker enables running Moltbot (an open-source AI personal assistant) on Cloudflare's infrastructure without dedicated hardware. Built using Cloudflare Workers, Sandbox SDK, Browser Rendering, and R2 storage, it demonstrates how the platform's improved Node.js compatibility and developer tools can host complex AI agents. The implementation includes AI Gateway integration for model management, Zero Trust Access for authentication, and persistent storage through R2. The proof-of-concept is open-sourced on GitHub, requiring only a $5/month Workers subscription to deploy.

    The Astro Technology Company joins Cloudflare

    The Astro Technology Company has been acquired by Cloudflare. Astro will remain open-source, MIT-licensed, and platform-agnostic, with all full-time employees continuing to work on the framework. The acquisition allows the team to focus entirely on building the best framework for content-driven websites instead of pursuing monetization strategies. Astro 6 beta is now available, and the framework will continue supporting all deployment targets while maintaining its open governance model.

    Building vertical microfrontends on Cloudflare’s platform

    Cloudflare introduces a Vertical Microfrontends template that enables teams to deploy multiple independent Workers under a single domain, each owning complete vertical slices by URL path (e.g., /docs, /dash). Using service bindings for routing, CSS View Transitions for seamless navigation, and Speculation Rules for instant-feeling page loads, teams can work in isolation with their own frameworks, libraries, and CI/CD pipelines while presenting a unified user experience. The Router Worker handles path-based routing, HTML rewriting for asset paths, and automatically injects transition code to make separate projects feel like a single-page application.

    What came first: the CNAME or the A record?

    A routine memory optimization to Cloudflare's 1.1.1.1 resolver accidentally changed the order of CNAME records in DNS responses, breaking resolution for clients like glibc's getaddrinfo and causing Cisco switches to reboot. The incident revealed that while RFC 1034 uses the word "preface" to suggest CNAMEs should appear first, it lacks normative language (MUST/SHOULD) making the requirement ambiguous. Some DNS clients use sequential parsing that expects CNAMEs before A records, while others search the entire answer set. Cloudflare reverted the change and proposed an Internet-Draft to formally clarify CNAME ordering requirements in DNS responses.

    Why We Built Our Own Background Agent

    Ramp built Inspect, an internal background coding agent that writes and verifies code autonomously. 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.

    Introducing OpenWorkers – Self-hosted Cloudflare Workers in Rust

    OpenWorkers is an open-source runtime that enables self-hosted execution of untrusted JavaScript in V8 isolates, providing a Cloudflare Workers-compatible alternative. Built in Rust, it supports KV storage, PostgreSQL, S3/R2 storage, service bindings, and standard Web APIs. The architecture includes secure sandboxing with CPU and memory limits, cron scheduling, and can be deployed with a single PostgreSQL database and Docker Compose file. The project evolved over 7 years from vm2 to deno-core and now runs on rusty_v8, aiming to deliver edge computing capabilities without vendor lock-in.

    Jade: "Cloudflare just published a vi…"

    Cloudflare published a blog post claiming to have implemented a Matrix homeserver on Workers, but the implementation is fundamentally broken. The code lacks critical security features like authorization checks and state resolution algorithms, contains numerous TODO comments, and makes false technical claims. A Matrix homeserver developer critiques the implementation as low-effort and potentially AI-generated, noting it would be more expensive than dedicated VPS hosting and incompatible with other Matrix implementations.
