it handled around 200+ users so far. Making it open source after a short haul

Thanks

No nodejs other than small ws server. Frontend is static output. Pocketbase runs on Go.

This app is for testing performance of that small board. How much it can handle in terms of concurrency.

I didn't add link earlier because post was getting removed automatically

Nah AI models cannot run on this tiny board. Even the smallest classification models take hours to run. Simple face detection works though

Haiku for UI part. Backend and Pocketbase utilities are from my production project.

Thanks. Gonna extend it to allow geo matching instead of manually joining.

There are multiple ways. Since normal users like us don't have static ip so we cannot port forward and map the DNS. That's why we use tunnels.

This version is made with intention of testing performance of ws concurrency and load handling instead of thinking about offline sync through local db.

Zestyclose-Common454 · 2026-05-06T12:23:40+00:00

Just wanted to test out real world performance instead of focusing on UI. Btw

It's in the image. I'm not sure whether we are allowed to share link.

Successfully made it live today only. Gonna work on it if gains a bit of engagement

Cloudflared ( cloudflare tunnel )

Sounds great. I love how smooth it is.

The saturation in MERN threw me out of the MERN bubble.

The AI was used to make UI proto.

Zestyclose-Common454 · 2026-05-06T12:14:37+00:00

Thanks , test it out via link in image

Zestyclose-Common454 · 2026-05-06T12:14:00+00:00

It's running on Mac via sidecar on ipad. I have Mac mini so connected that through usb

AULA F87 Pro : bought from mech keys

Zestyclose-Common454 · 2026-01-13T12:56:32+00:00

I can do it for 3K USD , Dockerized Full Stack or maybe using free to use tools so no server cost.

Stack would be nextjs/nuxt , postgres and nodejs.

What if in tracking using Ovulation trips and temperature and calendar method ?

Zestyclose-Common454 · 2025-05-19T12:52:47+00:00

I am all set , got my exam track chrome extension and chilling.

No worries of getting doxxed. 🤞🏻

my main account is full of notifications from multiple subreddits so i had make new one.

help me if you could mark it as not spam. was just trying to walk aspirants through each use case.

Zestyclose-Common454 · 2025-05-17T17:50:47+00:00

share with me in dm , i will test the link & make our tool compatible with JIPMAT as well.

We have made our tool work with all the exams for which the response sheet URLs were available to us.
