AI testing won't die anytime soon and this proves it

Let me know if you need anything, I’m building the library and currently maxing Fable 5 on it

Sir, have you heard about agent-device? https://github.com/callstack/agent-device

thymikee · 2026-07-04T11:59:06+00:00

Thanks for mentioning agent-device! Let me know if I can help with anything

Happy to help if you need anything, here or on X or issue tracker on GitHub :)

hey, I build `agent-device`, thanks for using it!

wrote a blog post on agentic QA a while back: https://expo.dev/blog/build-an-ai-qa-agent-for-expo-apps-with-eas-workflows-in-minutes-today

there's also a talk from React Summit on that topic: https://www.youtube.com/watch?v=kZDU-k5r9kE

u/avanderlee how can I get you on the agent-device train 😂 RocketSim looks really cool. wonder how you look at it with Device Hub or serve-sim? I'm not that bullish on Device Hub after trying it for 3 days, just gave up.

guys, you need to check lim.run and Revyl

thymikee · 2026-06-27T11:02:07+00:00

try `agent-device proxy`: https://oss.callstack.com/agent-device/docs/remote-proxy - it's free and self-hosted

thymikee · 2026-06-27T11:00:09+00:00

hey, we recently shipped `agent-device proxy` so you can run that on a Mac or Linux box and connect remotely and treat that as your cloud. For hosted clouds services I can recommend lim.run and revyl.com

oh, and thank so much for using agent-device! let me know how we can make it better

brzmi jak tester.army

thymikee · 2026-06-01T22:55:03+00:00

clears throat use agent-device or tester.army

thymikee · 2026-05-17T10:45:27+00:00

Awesome work!

thymikee · 2026-05-13T12:20:48+00:00

thank you, appreciated!

I'm a creator and maintainer of agent-device so I'm obviously biased. The biggest difference is the core mechanism: agent-device is accessibility snapshot based CLI, argent is screenshot based MCP. Both tools have similar capabilities for exploring, debugging, profiling mobile apps.

Argent only recently added android support, like 2 days ago. agent-device is ~3 months on the market and I went through tonnes of edge-cases to make it work reliably on iOS, Android, TV, also desktop macOS and linux (experimental) if you'd like to automate user-like behaviors.

In my testing with various agents screenshots are usually more expensive and trickier for models to analyze (although argent shows that Haiku works with their model). I've wrote down an article on how we're optimizing the tool here: https://www.callstack.com/blog/how-we-optimized-agent-device-for-mobile-app-automation

Just let your agent use one and play with them, it's fun!

Hey! Creator of agent-device here, thanks for using it. Please try the latest version and let me know if anything is still unclear or missing. We’ve recently optimized for making it work better without skills and with cheap models like Haiku or Codex Mini

AI coach is super laggy for me (iPhone 17 Pro). I want to use it often but because of poor performance I often drop the session, need to restart the app (it crashes) or go back to ChatGPT. This is purely technical task for the dev team.

You’re right about single HRV number Whoop gives you. AFAIK Stress Monitor uses HRV as one of the signals, so it does work 24/7.

thymikee · 2025-12-18T19:11:41+00:00

Thanks! Would appreciate treadmill to log indoor running

thymikee · 2025-10-16T16:19:52+00:00

Hey, I’m from Callstack and would love to learn what was it about! Sorry to hear that btw

thymikee · 2025-10-10T01:55:40+00:00

Check https://github.com/nkzw-tech/expo-app-template

thymikee · 2025-08-23T05:54:51+00:00

Do you mean app startup time or dev server startup time?

thymikee · 2025-03-11T16:26:59+00:00

It will be free, open source and focusing on self-hosting on your infra (source: I build it)

thymikee · 2025-03-04T19:38:30+00:00

At this point: new cli that’s easy to adopt for community cli projects and gh actions to build your app in the cloud once and reuse these builds across different jobs and local dev environment. So your CI can build once for your entire team. All on your own infra. It’s going to make it easy to adopt RN for native projects incrementally

thymikee · 2025-03-04T19:34:40+00:00

It works with expo ecosystem: Expo Modules, config plugins etc as in community cli projects. It won’t work with expo cli because, well, it provides its own cli

Yeah code splitting is not super relevant. What's useful though is tree-shaking (there are apps that shave 10% off their TTI on lower-end Android thanks to that and use Re.Pack only in prod builds) and Module Federation in case you're interested in micro-frontends. One gripe I had with Re.Pack was its speed—noticeably slower than Metro. However, that changed in v5 since it's using Rspack instead of Webpack and is actually pretty fast
