cloudflare

honojs/hono

A featherweight web framework that runs identically everywhere — Hono is a zero-dependency web framework built on Web Standards, running unchanged on Cloudflare Workers, Deno, Bun, AWS Lambda, Fastly Compute and Node.js. Its RegExpRouter avoids linear loops for speed, and the tiny preset stays under 12kB, appealing to developers who want one codebase across runtimes.

cloudflare/cloudflared

Expose origins to Cloudflare's network without opening firewall ports — cloudflared is the CLI daemon for Cloudflare Tunnel, letting origins connect outbound to Cloudflare so no inbound firewall ports need opening. It also supports Layer 4 access (SSH, RDP) to tunnel-protected origins via `cloudflared access`. Useful for teams adopting zero-trust access without exposing servers directly to the internet.

is-a-dev/register

Open-source registry for free .is-a.dev developer subdomains — This repo is the public registry behind is-a.dev, letting developers claim a free custom subdomain for personal sites via a GitHub pull request and JSON file. It's entirely community-run and open source, with a sister project, is-a.bot, recently launched for bot subdomains.

Grab your own sweet-looking '.is-a.dev' subdomain.

rivet-dev/rivet

Durable Actors built for agentic workloads at scale — Rivet schedules stateful Actors instead of pods: durable processes with built-in SQLite storage, queues, realtime connections, and scheduling, claiming 12ms cold starts and 72KB per Actor. Self-hostable and open source, it targets developers building AI agents, collaborative apps, and durable workflows across Node.js, React, Rust, and Cloudflare Workers.

Rivet Actors are the primitive for stateful workloads. Built for AI agents, collaborative apps, and durable execution.

hieunc229/mailflare

Self-hosted email inbox built on Cloudflare, Resend, or SES — Mailflare lets you run your own email service for custom domains, using Cloudflare, Resend, or AWS SES as backends. Beyond basic mail, it bundles shared mailboxes, calendar scheduling with booking pages, routing rules, and an AI assistant with MCP access—aimed at teams and professionals wanting control over their own email stack.

Email for professionals and teams

shuaiplus/nodewarden

Bitwarden-compatible server running on Cloudflare Workers

CluvexStudio/Aether

A Rust userspace client that chains MASQUE and WireGuard to beat DPI — Aether is a Rust censorship-circumvention client built on MASQUE over HTTP/3 and HTTP/2, with a local SOCKS5 proxy. It verifies gateways by actual traffic, not just handshake, and supports nested modes like WireGuard-over-MASQUE, MASQUE-in-MASQUE, and Tor exits for DPI-heavy or UDP-throttled networks.

A Rust userspace WARP core for censored networks, built around MASQUE over HTTP/3 and HTTP/2.

akdeb/ElatoAI

Realtime Voice AI with 100+ Models on Arduino ESP32 with Secure Websockets and Edge Functions for AI Companions, and Devices

rociiu/talorys

A personal AI agent you own, hosted on your own Cloudflare account — Talorys is a self-hosted AI assistant deployed with one npx command into your own Cloudflare account, no external server or vendor database involved. It handles chat, long-term memory with optional semantic recall, tasks, notes and scheduled automations, aimed at single users wanting a private, free-tier-friendly, telemetry-free assistant.

Your personal AI agent in your own Cloudflare account. Chat, memory, tasks, notes and scheduled reminders, deployed with one command: npx create-talorys@latest. Free-tier friendly, single-user, no telemetry.

cloudflare/mcp

A Cloudflare MCP server that shrinks 2,500 endpoints to 1k tokens — This MCP server exposes the entire Cloudflare API using Code Mode, cutting context usage from ~2M tokens (raw OpenAPI) or ~1.17M tokens (native MCP schemas) down to roughly 1,100 tokens with just 3 tools. It supports OAuth or API token auth and targets agents needing broad Cloudflare control without blowing their context window.
