I'm struggling

Hey, I've been working on a SaaS product for around 8 months, but I'm struggling. It's open source, and we've had nearly 40 contributors with 800+ commits! But we've made little progress. I've worked on the project on average 2 hours a day. We've got a few core features, not too well polished, and have a few ideas for what needs to be added to step up the game. But every new feature feels daunting. Feels like I'm just going to add more and more rubbish code, and add more and more bugs. (we have... a lot of bugs since we stopped adding tests). Yeah that's right, I stopped adding tests. I got to the point where I felt like development was too slow, so tried to speed it up by ditching common practices and even stopped writing tests. Well there's mistake number 1. Since then we've added a few cool features, but they're buggy, we don't know if they work properly, and it's honestly STILL not moving enough. I've came to product hunt to see others products, and support them. But it's just making me realise more and more how rubbish mine is. How can I get out of this spiral? Any tips or past experiences you guys have had with this? I'd be happy to answer any questions, thanks for taking the time to read my start to a journey, you guys have some incredible products!
