it has begun

People keep asking us if @jazz.tools will have vector search... What's better than building a first class vector search feature for Jazz in maybe a couple months? A single person right now being able to ship it as a small, very neat, very high quality library *on top of* Jazz! vimeo.com/1111603758

LLMs are a crystallisation not only of human knowledge but also of the human condition I think there is immense value in them encoding both - the surprising commonalities in our experiences, struggles and hopes - *and* the myriad dimensions of individuality

Given our realisation that *actually, @jazz_tools is a database* (see QT)... ...we're hosting another meetup in SF this Wednesday! (RSVP below!) Thinking of Jazz as a DB begs the question: how does it fit into the stack? bsky.app/profile/jaz...

narrative update Jazz isn’t replacing databases and backends Jazz isn’t local-first only Jazz isn’t a sync engine only Jazz is simply a *new kind* of database 🧵

FUTURE OF CODING LONDON is next week! Last chance to submit your awesome demos! lu.ma/lo2medup

I’ve been using “vibe coding” in a looser sense than Karpathy’s “fully blind” definition, for good reason. The biggest impact of AI tooling that I’ve seen is senior engineers a) using their ability to clearly specify what they want and *build* extremely quickly with LLMs

The wait is finally over! It’s time for another FUTURE OF CODING LONDON Tuesday, July 22 @ 18:00 Kindly hosted by Granola at their office Sponsored by @jazz.tools RSVP here: lu.ma/lo2medup Demo/Talk submission here: foc-london.notion.site/21c379f0e4c...

Lots more interesting thoughts on this soon, but as I get deeper into fully auto-running agents, a simple realisation (and I cannot overstate this): Vibe coding is the first time computers have felt as magic again as they have when they first felt magic to me

Two weeks after alpha-3 which foreshadowed our move to @jazz.tools for greater stability, alpha-4 gets it done! blog.muni.town/roomy-space-... Special shoutout to @flo-bit.dev who took the lead on this release. Up next is bridging so Roomy & Discord (later Matrix) folk can share the same space.

Watch @anselm.io talk about how local-first is accidentally perfect for the AI age. youtu.be/e3-yIWGNBLQ?...

My full talk from @localfirstconf.com is up! Featuring 1y of progress on @jazz.tools And: two big announcements + the most sketchy, yet successful demo I've ever done. - Waffle, a Discord/Slack alternative built on Jazz - Soul, our upcoming AI toolkit for Jazz www.youtube.com/watch?v=e3-y...

> The AI just is "one more collaborator" and you just dump the tokens into Jazz state as they come in. This is the correct mental model

Streamed LLM responses are the perfect example of why we didn't base @jazz.tools on an existing DB, but are building a new backend + DB from scratch. Originally we just wanted to support Figma/Notion-like apps where we knew we had to sync 100,000s of tiny edits per second... 🧵 x.com/marbemac/st...

Sync engines are an incremental improvement to the "centralised server + client" model - the minimal possible step towards the real-time nature of apps today. But we can do much better 🧵

Love meeting new builders online me: “Hey Jazz supports ProseMirror now, we should build a ProseKit example or something” *minds my own business for 3h* @ocavue.bsky.social: “here’s the example”

@localfirstconf.com is off to a fantastic start, the number of new people is mind blowing. For us at @jazz.tools, today was all about getting hands-on and helping people building cool stuff with Jazz - and handing out our first vibe coding certifications!

Just learning about Jazz and I'm beyond excited. I've been wanting to build something similar for a long time. Checking it out now but this looks amazing. Excited to hear more about all the announcements.

Working on some of this at @garden.co has been some of the most exciting & fulfilling work I've ever done. Fantastic software by fantastic people. Looking forward to meeting folks at this year's @localfirstconf.com – the future is now ❤️🎵

Megathread of everything we're announcing for @jazz.tools at @localfirstconf.com It's been a hell of a year in the best sense and I can't wait to share what we've been cooking. (And this doesn't even include our "one more thing" 🤫) Stay tuned as I expand on details over the next couple days!

Join the @jazz.tools team at Local-First Conf! - learn how to vibe-code apps with Jazz - get a first glimpse of AI that “already knows how to use your app”

I love doing adopter support calls for @jazz.tools "No you don't need to do that..." "This extra indirection isn't necessary..." "Yes, you can use CoValues as both UI state and the persisted source of truth - you don't need to copy back and forth" "No you don't need to 'save' "

Discord driven development Shoutout to @jmsv.bsky.social for the 3h suggestion-to-🚢 Shoutout to @[email protected] for the months of gruelling work in the ProseMirror mines that made this a quick win

Nothing better than telling people to edit just their package.json for a 12x perf improvement. I still think we can do better for this particular hot path internally. But their app’s “screen of everything” *cold start* is now bottlenecked by React & the DOM! bsky.app/profile/jaz...

Jazz 0.13.20 released - with significant sync and rendering perf improvements We have been focusing on performance and stability over the last month, polishing our internals, sync protocol, and subscription engine.

Security is the most subtle challenge in full-stack apps. Many devs still re-invent the wheel, building access control with low-level tools like RLS (or worse, ad-hoc backend code) 😱 The security design of @jazz.tools is a godsend for vibe coders (and experienced devs!) 🧵

Very happy with how this comparison page turned out and proud to have co-sponsored it as @jazz.tools! The fact that such a thorough, fair comparison page could be created by competing vendors and open-source projects is a testament to the spirit of collaboration in the local-first community.

coming soon

Just finished working through the [React tutorial](jazz.tools/docs/react/g...) at @jazz.tools and it _is_ pretty impressive how easy it is.

Last year @localfirstconf.com, I showed @jazz.tools to a wider audience for the first time - a humble MVP built in my spare time I found investors, team members and our first prod user there ❤️ This year, there'll be 13 of us and so much progress to share! Stay tuned 🎵

setting a bad precedent by letting adopters successfully bully us into writing docs faster

Jazz is not about the code you write, it’s about the code you don’t write

One of the most interesting new web app libraries is @jazz.tools, which makes it super easy to sync collaborative multi-user state between a bunch of clients while managing user/group ownership and permissions as well. See jazz.tools and jazz.tools/examples.

@jazz.tools has made working on this an absolute delight. As a designer who spends months working off of local JSON to put off backend wiring ... Jazz lets me do just that. Treat data as state, and it handles sync and storage and whatnot. Amazing!

we were going to write a post about this but it’s really cool that @threepointone.bsky.social did so first because you’ll believe him much more since he has no vested interest (*vsauce mystery sound* or does he?) anyways we’ll still write our post as well

These excellent illustrations by Adam Nyberg (on X) are a chance to explain how @jazz.tools goes further than a "sync engine": - By also making permissions local-first, further abstracting your business logic into something declarative - By using an app-agnostic sync & storage server

Devtools that are really serious about local-first should make their own DB + cloud

Alright, officially announcing the Local First Academy first workshop (signup and link to follow) On Saturday February 15th at 12pm EST, @dolearning.dev and I will be building an app with @anselm.io's @jazz.tools More details to follow!

Many in the Future of Coding community have been wondering… What is the scrappiest fiddle of them all? (cc @todepond.com) The answer is: the one that doesn’t even exist yet! This is your reminder that you can submit non-existent demos to Future of Coding London! You still have almost a month!

The key metric for new devtools is of course "time to working demo that impresses my significant other"

People often ask me what’s so special about Future of Coding London. “The people” is one obvious answer. “The demos” is where it’s really at. (thread…)

Hiring for a senior fullstack dev with a hiring company that prides themselves with diversity metrics Total candidate pool: 42k Of these “not identifying as male”: 13k Of these “identifying as female”: 3k Actual applications I have received from women: <1% Utterly ridiculous

Stop liking the post and start commenting some stuff!!

Dear Future of Coding community: Alan Kay really liked your questions, and now he has some for you! “What do you think about the fact that most programming languages today are very similar to the ones in the 80s, considering that before then there was a vibrant diversity of them” And… 👇
