Show HN: I built an open source (GPL) ATS

Hi there!

A while ago I built an open source ATS a while ago when I was hiring for some techies at the company I worked in.

I wanted to have a simple way to handle the basics without using a spreadsheet and found there were no easy alternatives that were free / open-source that could be self hosted or even ran locally (in an easy way).

All the solutions were enterprise software or offered a some sort of saas structure for it.

Hence, I build this MVP during a weekend and actually hired a few employees using that as a source of truth.

I set the license to be GPL because for that reason, if you want to build one and sell it, be my guest, but I liked the idea of having a software like that to be fully open and available. Obviously it's limited and tailored to the needs I had, but I found it fun to do.

From the repo:

<quote> The whole point of this project is that there's so many ATS platforms out there that are either too expensive, too complicated, or too restrictive. This project aims to be a simple, open-source alternative that can be self-hosted and customized to your needs.

For that reason, I've chosen the GNU GPLv3 license to ensure that any modifications or improvements made to this project are shared back with the community. This is to prevent any one entity from taking the project and making it proprietary. </quote>

As a fun fact the first version of it was done by Devin, but I had to do a huge refactor to make it actually work xD It's a simple Next.js + Prisma app. I use some tooling from Vercel like the storage, but could be ported to S3 compatible to self-host minio or just general compatibility.

---

I do not have plans to mantain it actively, but wanted to share this project if someone is interested, or just your thoughts in open sourcing these type of (core) tooling, even more now in the world of AI we live in.

You can find the repo at https://github.com/tarasyarema/oss-ats and there's a live demo at https://demo.ats-oss.org

What do you think? Specially on

1. Having 100% free and GPL licensed for core software solutions 2. Any alternatives of open source ATS that are working now? 3. Interest in using it?

PS: Disregard the styling and tech designs decisions, I just wanted to have something working fast enough (e.g. I'm not a fan of Prisma, but I guess for this it was easy to setup and use)
