It's already been there for years. GlitchTip is fully FOSS and able to be self-hosted. I wouldn't add proprietary code.
🤔 🛂 Sentry io gets caught by my Pihole Blacklists, I can’t resolve that domain. For GlichTip, I read this claim on the Gitlab This is a clone of Sentry’s open source repositories, taken before they switched to a proprietary license.
Ok I got it, it's a Django app, released under MIT https://gitlab.com/glitchtip/glitchtip-backend
