Love seeing all the discussion around feature flags lately.

AI apps need feature flags even more than traditional software. Models, prompts, tools, routing, and experiments are all changing constantly, and feature flags let you ship and iterate safely.

Feature flags are also critical infrastructure. Every evaluation is on the hot path, so performance and reliability matter just as much as the feature set. The best feature flag service is the one you never have to think about.

Over the past few months, I've been working on Flagship at @CloudflareDev. We announced our open beta ~50 days ago, and we're already serving billions (yes, billions 🤯) of flag evaluations every day.

We're actively building Flagship, so this is a great time to help shape the product. If you've built with feature flags before, I'd love to hear what's missing, what we're getting right, and what you'd like to see next.

Hey @OxcProject can you please change how you format type level ternaries?

The staircase is awful for diffs. Change one line and the whole thing gets messed up.

hi everyone! I'm a PM intern on RealtimeKit at @Cloudflare, the SDK for adding live video, voice, and chat to any web or mobile app without building WebRTC yourself.

Using it, want to learn more, or have feedback? Would love to chat, DMS are open or book time with me below 🫡

Really wish the double tap gesture on watchOS could trigger Siri.

It's more reliable than raise to speak or the "Hey Siri" activation phrase, and pressing the crown requires two hands.

This was how it started for me 😅

if vscode crashes one more time, i'm moving to vim

NPM doesn't want Drizzle to publish any more versions. I'm not joking. Please, if you know someone at @npmjs/@microsoft send them this. The registry is in a bad state as is, we don't need new shenanigans.

🎉 Big news: Node.js is changing its release schedule for the first time in 10 years.
From October 2026, less to remember and easier to know what's Current or LTS.
Here's everything you need to know 🧵👇

oxlint/oxfmt/tsgo are absolute game changers, your CI is unnecessarily slower without them

[Cloudflare Changelog @CFchangelog]

You can now attach cron schedules directly to your Workflow binding in wrangler.jsonc. No separate scheduled worker needed for recurring jobs.

i don't know if it's the guardrails or the spell it cast on the model, but i'm oneshotting stuff like never before

@jamesqquick @Jilles @NithurM It’s an incredible TUI for for git!

[Matt 'TK' Taylor @MattieTK]

Before, setting up tunnels for local dev with @Cloudflare meant running cloudflared and jumping through hoops.

Today: no more hoops! Tunnels are built into your local dev server, and you can configure your own static addresses in one line of configuration. 🥳

For me, this is a modifier that turns my IJKL keys into arrow keys. It’s so nice.

Criminal that this key is anything but backspace.

Try remapping it. You'll see what I mean.
