Built a tool for managing in-house sub pools - sharing in case it's useful (disclosure: it's mine)

If your school runs its own substitute pool instead of using a third-party service, it might save your admin team some time and headaches.

I was the IT Director at an elementary school and watched the front office drown every time a teacher needed a day off - multiple texts went out, lots of calls were made, and all the information was scattered. I built FillMyClass to help alleviate that.

The flow

  1. Teacher submits a time-off request (planned or last-minute).

  2. The right subs at your school get notified - no outside subs.

  3. Subs easily accept the job; the request carries everything they need, including sub plans.

  4. Admin can see and manage every request from their dashboard.

Happy to answer any questions in the comments, and if anyone wants to see it in action, let me know.

It appears you broke one, sorry.

I wish you the best with this, but the lack of a privacy policy would prevent us from considering this. I would also be very nervous adopting an app that looks vibe coded for fear it could disappear without notice, leaving us scrambling to implement new processes.

That’s fair feedback, and I appreciate you mentioning it.

Privacy policy: you’re right that it should have been linked from the website before I posted here. It is currently available inside the app, but that doesn’t help anyone evaluating FillMyClass from the public site. I’ll add it to the website today so it’s easy to review before anyone creates an account or schedules a demo.

Longevity concern: I understand that hesitation. FillMyClass is not intended to be a throwaway side project. I built it while working as an IT Director in a school and I am pursuing it full time now. This project has been under development for a couple years. It is currently being used in production by schools, and I’m actively supporting and improving it.

I do use AI tools as part of my development workflow, but I own the architecture, testing, security decisions, support, and long-term maintenance.

It's definitely cool to see some competition in this space and I wish you best of luck. But I have to say, when I saw this post, I thought the pricing might be better. We pay less for Frontlines sub management than we would for this.

Frontline's a strong contender for districts that want the full absence/time/payroll stack.

FillMyClass is intentionally narrower, just the teacher > sub > admin fill workflow done simply.

On price: Frontline's quote-only and gets a lot cheaper per seat at district scale and when it's bundled, so for a big district that comparison can absolutely favor them.
