lim.run (YC P26)

extend cloud sandboxes with xcode, simulator, android and others. in production at replit, rork, momentic and more.

[lim.run (YC P26) @limrun]

Just launched in Replit!

We believe all coding will be done in the cloud but today’s clouds aren’t set up for that.

With Limrun, your agents will do everything that’s possible in your laptop but at cloud scale.

Starting with mobile dev!

[jordwalke @jordwalke]

Introducing real iOS and Android device testing, right from your browser.

If you've ever:
👉built a @Replit mobile app and had no way to test it on a phone
👉 been solely on Windows/Android and don't touch iOS

…this is for you!

[lim.run (YC P26) @limrun]

Now it’s time to ask your vendors about certified pentests they did, risk assessments and relevant security partnerships.

[muvaf @muvaff]

That’s why we are partners with @calif_io , the group uncovered the PHP vulnerability and part of the @OpenAI Daybreak program.

In security, anything short of the best is just useless.

Who said cloud agents can’t do iOS dev?

Turns out our website needs to be optimized for the folded screen

Speed, cost, concurrency. Pick all 3 for your e2e tests.

[lim.run (YC P26) @limrun]

Run your tests with the fastest simulators on earth with high concurrency.

Go check out @FabraixHQ for securing your mobile apps!

[Fabraix (YC S26) @FabraixHQ]

🚨 New feature alert: Nyx can now test your mobile app agents end to end.

We’re launching our @limrun integration, bringing agent security testing to iOS and Android apps.

It uses the app UI to reach your agent, then probes for gaps in its defences with the persistence of a motivated attacker 24/7.

If your next app release includes an agent, we’d love to help you test it.

Plugin extensions are so cool 😎

Building a native iOS app with Codex + Limrun. Build → try → annotate → iterate. All in one place.

Feels like it’s part of Codex.

[lim.run (YC P26) @limrun]

Shape matters, too.

iPhone Duo support and the new 3D view are available to use in our console and you can embed it in your web application with a single React component!

Try it: https://t.co/csC6KYevV8

[Tunya Irkad @irkadtunya]

i've joined @limrun as Chief of Staff.

i've watched this company take shape from its earliest days, including months when @muvaff was building it alone. today our product is used by platforms like @Replit and many other undisclosed companies!!

we are growing fast and looking for more people to join us: https://t.co/fX2pYjobHp

maaany many other exciting news to be announced!

let's build!

Duo is available now!

@steipete Another pain was to have the dev loop fast enough and in the cloud for scale which is PITA with bare Mac VMs, and that’s what we solved at @limrun

[lim.run (YC P26) @limrun]

Start @tryreplicas from slack and get a fully validated PR, now including mobile!

[Saai Arora @SaaiArora]

you can spin up a simulator for android and IOS apps directly in @tryreplicas by asking your agent to do so.

this is a game changer when I want to test out new features in our mobile app.

Give Devin an iPhone.

Limrun provides coding agents real iOS simulators and Android emulators in the cloud - ready to build, run and test mobile apps.

[hasan türken @turkenh]

Grok @bot can run a mobile dev factory with @limrun.

[lim.run (YC P26) @limrun]

You read it right, we power some of the craziest loops and graphs that our customers built to autonomously improve their mobile apps.

Just “npx lim run” and see the magic.

[Yoko @stuffyokodraws]

Good loops need good infra: the verifier, systems of records, harnesses, state control and execution substrate

Loops won't run in prod without infra:

[lim.run (YC P26) @limrun]

Your cloud agent deserves every capability your laptop has.

Glad to power the mobile dev in @tryreplicas !!

Go try now.

[Connor Loi @connortbot]

Introducing Mobile Testing in @tryreplicas

Replicas agents can now build and test iOS or Android apps. Watch them do it live in our dashboard, view screen recordings, or jump in yourself.

Wonder how the simulator is so good you can play a 3D game 🧐

[Alex Nguyen @alexcooldev]

This is the full video showing what I made with Rork and Claude Fable 5.

It’s super simple because I wanted to test Fable 5 using completely natural language (and even in Vietnamese) to see how well it would perform without any fancy prompts and it worked surprisingly well.

I simply uploaded screenshots of Subway Surfers and told it to "clone this," and it did a pretty solid job.

Also, Rork already has built-in integrations to generate game art, sound effects, and 3D models, so I didn’t use any external tools at all. It cost me around 500–600 credits.

As I mentioned in my previous video, I wanted to test Claude Fable 5, and since I’m a Rork partner, I had free credits to use.

Right now, instead of using Claude Code and then wiring up separate 3D tools and everything else which takes way too much time and $, I just use Rork to build everything and showcase it here. So yeah, that’s my workflow.

[muvaf @muvaff]

Review is the bottleneck and @mainframe team knows how to solve it.

Must read before starting to build your software factory 👇

[lim.run (YC P26) @limrun]

A single skill file and your cloud agent can build any mobile app!

[Brett Bauman @brttbmn]

all it takes is 1 skill file to give the cursor iOS app its own simulator for building iOS apps

I use @limrun to do this which lets me build cog using cog

it installs the app, drives the simulator, and adds screenshots/videos to the PR

[lim.run (YC P26) @limrun]

Did you know @DevinAI can build iOS apps, too?

[Jared Zoneraich @imjaredz]

Kudos to the team! @limrun is a great product
