What if we gave you the ability to search your production logs from an alternate universe? Or several hundred thousand alternate universes -- a multiverse in which you see years of operational outliers in a single night?. And what if -- even better -- this multiverse comes with a.

RT @glcst: Turso, the next evolution of SQLite (previously codenamed "Limbo") reaches its first alpha milestone and first official release.….

RT @ordepdev: Such a great talk from Will Wilson (@AntithesisHQ) on software reliability. Planes rarely crash despite insane complexity—why….

Even after being incident commander for @OpenAI 's largest ever outage, Ben Eggers still believes in testing in prod. Here's his talk from #BugBash 2025.

RT @glcst: Always cool to see @AntithesisHQ in action. We just deployed new code for caching of the sqlite b tree pages. It survived 2 day….

RT @debasishg: Testing and observability convergence at a different level - another case for deterministic simulation testing. Nice BugBash….

One of our Summer interns is integrating Fray with Antithesis for even more bug-finding deliciousness! 🪲.

We think the testing/observability divide is as false as the software/hardware divide. And to prove the point, we're launching a feature that unites them.

A great blog post from @jessejiryudavis @MongoDB about combining Antithesis and formal methods. There are many paths to reliability, and you have to walk all of them.

This was one of the most requested recordings from #BugBash this year -- Lawrie Green's terrific explanation of autonomous testing. Lawrie makes it sound so simple and so logical, it makes you wonder why this isn't how everyone tests their software.

We're thrilled to be part of @redpoint’s 2025 InfraRed 100 list, which highlights 100 transformative companies in cloud infrastructure. Proud to be in such outstanding company - congratulations to everyone listed!

Tomorrow, June 10th is DC systems no.7.Smart talks. Smart people. Maybe a few dumb memes. Featuring @danslimmon (ex-Etsy, ex-Hashicorp) breaking down Queuing Theory and @micharu123 (@harborlabs) walking through what secure-by-design means when human lives are on the line.

The folks at @TigerBeetleDB were some of our earliest customers at Antithesis, so it was such a pleasure to be able to work with both them and @aphyr together. It's bucketing in DC area this weekend, stay in and read the report!.

Not to sound like monomaniacs here, but have you ever thought about all the code out there that's supposedly un-testable?. @mitchellh came to #bugbash to talk about how he thinks about making supposedly un-testable things testable -- and he makes a compelling argument that this.

Will was on the @StackOverflow podcast yesterday! It's less about DST,* and more about taking risks on people, running away from CS, and fixing the new things first. *Look, this is still a podcast with us, so there's really quite a lot about DST in it.

Next Tuesday is #AWSSummit DC, but the real party will be out here in Vienna, at #DCSystems 007!. If you're in town, come join us -- or if you're a DC native, come escape the madness downtown!. We have @danslimmon talking about Queueing Theory, and @micharu123 from @HarborLabs on.

If you saw Will's talk at #WebSummitVancouver yesterday and want to learn how to actually do the kind of testing he spoke about, come join our masterclass at 1pm Pacific!.

In just ten years, deterministic simulation has gone from an incredibly niche concept practiced at one company, to publicly endorsed by our friends at AWS! What a huge win for this community:

If you're at @WebSummit Vancouver come say hi! Will's taking to the AI stage at 3:25 to talk about why AI won't stop your software from breaking. And if you'd like to know how to implement the ideas he's talking about, we'll be doing a masterclass tomorrow at 1pm tomorrow.
