Massive thanks to the people building everything we build with.

iMessage meets desktop harness running on @Cloudflare + @thelinqapp + @zero__ms + @browser_use

[Bodhi Hawken @BodhiHawken]

@joodalooped @zero__ms is insane, been running it in production all year.

I almost feel bad that it’s open source, the tech is on another level.

[Aaron Boodman @aboodman]

Another day, another Zero product launch.

I don't think there a huge number of movie producers in my follows, but if there are - check out @saturation_io.

Thank you @jensjacob24 for entrusting us with sync services for the relaunch.

[Aaron Boodman @aboodman]

Proud to be providing sync to Operate 2.0 with Zero. Looking forward to using the fastest CRM on the planet.

Zero crossed 100k weekly installs last week. Out of curiosity, I checked how our pace compares to some other projects I respect. Was surprised to find we're beating Supabase's pace by over a year (!! - as measured by time from public launch).

Now of course it's hard to compare these numbers for much. This is npm installs which is notoriously noisy. It's more of a coarse proxy for usage than anything else.

And the world has changed a lot in the meantime - AI means usage of all kinds is up. The whole world is just turning the crank faster.

I think the key takeaway here is that infrastructure takes time. Today Supabase is an 800lb Gorilla and Convex is coming up fast. It's easy to forget the *years* of investment that it took to get there.

[Aaron Boodman @aboodman]

Really proud to be a part of this product. Take a click around the UI (with the sound on!!) – it is an absolute delight, and insanely fast thanks to @zero__ms. Shades of early Slack and Heroku.

[Sriket Komali @SriketK]

fire. assuming ur using tanstack query. if you ever want to go a step further, id recommend storing data in indexed db to avoid network requests for mutations and queries. shouldnt need a network request everytime a user fetching the same data. Look into @zero__ms . this is what we used for cobalt. heres a demo. and code is opensource. https://t.co/5vEjD1Pwxi

We at @tines_hq have been using @zero__ms to power a big new product we’re launching soon.

Zero has become one of my favorite ever abstractions for building software, alongside React – proud to endorse it!

[Aaron Boodman @aboodman]

👀. Been a fan of this team forever. Very proud to be working together.

So @chadburggraf, the guy behind this also created @assetbots - one of the first @replicache implementations.

What's the word for when a founder creates something on your infra, gets acquired, starts something new, and uses your new infra?

[Elias Wambugu @eliasdevs]

@odysseus0z @instant_db @ElectricSQL We use @zero__ms for @astracollab and all of our users love it!

Nice X handle, @ano__chat. A new member of team double-underscore.

Cloud Zero is now available and production-ready: fully managed Zero hosting from the team that built it.

- no severs to deploy or maintain
- 24/7 monitoring
- automatic zero-downtime updates
- optional bring-your-own-cloud deployment
- migration help for existing self-hosted setups

[Aaron Boodman @aboodman]

When we started Zero, we weren’t even sure there _was_ a correct design for the kind of query-based sync engine we dreamed of. We spent two years finding that design, then hardening it for production use.

We always imagined a hosted version too, because (a) running a sync server is never going to be fun 😅, and (b) gotta make money!

Starting late last year, we were finally able to begin work on that hosted version. Initially it was invite-only and small, but we're now in production and syncing thousands of messages per minute for teams like @productlane, @passionfroot, and @shipper_crm.

Cloud Zero is production-grade Zero hosting from the team that built it:

- no servers to run or maintain
- 24/7 monitoring and alerts
- automatic zero-downtime updates
- fast NVMe-based architecture
- run as traditional SaaS or in your own AWS account

We’re onboarding manually, but it’s quick. And if you’re already self-hosting Zero, we’ll help migrate your setup.

Productlane was one of our very first Replicache customers.

As their top users started pushing hundreds of MB in a single workspace, they started hitting its limits.

We built @zero__ms for exactly this problem. It lets you intuitively control what syncs and when, balancing startup vs interaction speed.

Now @productlane is fast again, even for the biggest customers.
