The Holy Grail for web apps is when my Passkey can unlock local private data.

Sync seems to be having a moment among web developers!

I bought my ticket already and will be there! Figuring out which of my colleagues at @inkandswitch.com might join us, and maybe a little community hacking alongside.

Have something to say about sync engines, local first, or sync as an enabler for AI agents? Submit your talk soon.

Announcing Sync Conf 2025. Join us in SF on Nov 12th.

“The syncing model solves a fundamental challenge of most modern web apps out there, and it does it in a way that feels, well… better.” frontendatscale.com/issues/50/

“The concept is beautifully simple: instead of your app being a fancy form that sends data to a server, it has its own local database. Sometimes the server is just another client to sync with. It can be a fundamental inversion of how we build web applications.” bytemash.net/posts/i-went...

“It’s magical to update a row in Postgres and instantly see the UI reflect that change. This simplifies background tasks, makes multi-device and multi-user flows easier to reason about, and reduces boilerplate. Just write to Postgres and let the sync engine do the rest.” neon.com/blog/tanstac...

A helpful graph made by @stevekrouse.com on the inverse relationship between vibes and understanding in AI assisted code. Put a few thoughts down here: maggieappleton.com/2025-08-vibe... Original article: blog.val.town/vibe-code

📄✨ New paper! Emilie Ma (kewbi.sh) and I looked at the problem of users of end-to-end encrypted apps recovering their private keys if their device is lost, broken, or stolen. We found a cryptographic approach that is decentralised and resilient against social engineering arxiv.org/abs/2507.21122

Do you write TypeScript? Enjoy Automerge? Love building both tools and community? You might be a great fit for our ✨new✨ Automerge TypeScript Maintainer role! www.inkandswitch.com/jobs/automer... (Remote role, 🇬🇧 UK-based preferred but not required)

Automerge 3 is here: the heart transplant is complete! Huge improvements in memory usage and (in most cases) correspondingly big performance improvements too. Backwards compatible on disk and the network so there's no reason not to upgrade today: automerge.org/blog/automer...

This pattern is at the core of how @livestore.dev handles sync, offline support, and conflict detection — and it’s been really fun diving deep into it while working on the upcoming course. If you’ve ever wanted to build local-first apps that sync like magic, this approach is worth understanding.

Introducing… (Not Boring) Camera 3 years, 100+ prototypes, and wild graphics tech to make our perfect camera. Only to say… forget perfection. Just have fun and capture life’s beautiful chaos. Hope you love it as much as we do—thumbprints and all 🖤 notbor.ing/camera

Nice impressions from @localfirstconf.com (photography by Susanne Elsässer)

Reflections as an organizer of @localfirstconf.com this year Twice the size (350+ people) and twice as much content (two full days of talks) I think we did reasonably well on keeping quality up even as we scaled quantity!

My takeaways from this year's @localfirstconf.com Last year we collectively were at the stage of “hey this syncing tech is cool, you don’t need the cloud as much” and “hey, we have a community here, who knew?” This year it felt like the community had more cohesion and sense of identity.

We're counting down days! Here’s Everything You Need to Know for Local-First Conf 2025

The cleverness isn’t in the lenses; it’s in that user-owned fabric. Build it offline-first, merge-friendly, and secure by default, and the rest is just UI paint. Someday today’s file-juggling will feel like punch cards. Let’s start weaving the fabric and sanding the lenses now.

What if you didn't need git to collaborate on games? We've been prototyping a new approach to collaboration in Godot: live and async collaborative editing, with branches and diffs, built right into the editor. We're looking for people to test out an early version, see link in next post:

Sync/local-first fits together beautifully with streaming LLM chats, as illustrated by the videos in this post

Our new research track is called Universal Version Control and it's about exploring how to bring the power of version control to every person, on every kind of document and every kind of collaboration. www.inkandswitch.com/universal-ve...

Today we're launching the new tldraw ai module. If you're a developer and want to experiment with LLMs on a whiteboard, this is for you.

Recently got to chat with @lucaronin on Refactoring podcast! We talked about the overlap between AI, data ownership, and local-first software; problem-first vs technology-first solutions; and complexity homeostasis for dev tools. Listen here: refactoring.fm/p/user-expe...

What if a spreadsheet cell could hold multiple values at the same time? That's the idea behind Ambsheets, a project I've been working on w/ @geoffreylitt.com at @inkandswitch.com. It's a new spreadsheet that makes it easier for you to explore many possibilities simultaneously. 1/2

It's riveting seeing how fast the "build vs buy" tradeoff is shifting in software. This is a perfect example from @randomwalker.bsky.social : he built a little reading app with ChatGPT, rather than trying to find an existing one. x.com/random_walke...

Reluctantly spent part of the weekend trying to interpret the DeepSeek R1 manic panic happening on the hell site. Took a minute, but wrote myself notes to clarify the basics: maggieappleton.com/2025-01-deep... TLDR; a cheaper, higher-quality, open-source reasoning model for everyone. Net good.

Here's my end-of-year review of things we learned out about LLMs in 2024 - we learned a LOT of things simonwillison.net/2024/Dec/31/... Table of contents:

❄️ Winter break hack project ❄️ Sorting my email (Inbox, FYI, Junk) using gpt-4o, fine tuned gpt-4o-mini, Lllama, and DistilBERT.

The accounting tool Bench shut down with no warning 3 days before the end of the year. They had raised $110m in venture capital. The app is no longer accessible. There will be a way to export your data, but it's not available yet. File over app is not just for individuals.

I've built FizzBuzz in @tldraw.com computer! Such a creative tool—lots of potential for teaching newcomers programming.

At @inkandswitch.com we are starting a new project to research better version control tools for making games. One hypothesis: collaborating on a game should initially be as simple as working on a Google Doc, with concepts like branching introduced gradually as needed.

we've been making an ai thing with @GoogleDeepMind

I wrote 4,000 words about the end of the Twitter Era. As we walk through the graveyard of social media, we explore network effects, decline, death, and rebirth. www.sandofsky.com/end-of-twitt...

In a local-first app, the whole UI is constantly reacting to changes by other users. This is mostly a good thing, because you always see the freshest data and there's no fighting with cache expiration. But it can also be disconcerting when things appear to change randomly.

A new chapter begins today... I'm joining The Browser Company as GM of platform!

Writing is important work. Books, news articles, and science papers often involve many stakeholders and complex workflows. That's why we've chosen writing as our first domain for exploring the Ink & Switch vision of "version control for everything." 1/

After a few months of rest post-Muse, I'm ready to get back in the game! First up: “back to the lab" with a new Ink & Switch research project on version control. I'll post excerpts from our lab notebook periodically. Or read it on the web or via RSS here: www.inkandswitch.com/patchwork/no...
