I judge it on a case-by-case basis by just looking at a few recent commits and the feel of clicking a few files in the repo. For OpenLogi I get the wrong type of vibe code vibes and at the very least that means the project might become an unmaintainable mess in a year and that means I don't want to come to rely on it. At worst it means security vulnerabilities.

That being said: I wouldn't really trust SaaS to not be vibe-coded either. The only difference there is that SaaS likely has a financial incentive to stay maintainable so you could argue that helps.
