this shows all the hallmarks of being vibe-coded slop (emoji-studded readme being the first dead giveaway)
it’s “open-source” but https://www.neatmail.app/ has a Pricing tab
the self-hosting instructions mention a “DodoPay account (payment processing)” with no explanation of what payments you’d be processing if you’re self-hosting it.
and one of the listed “AI Integrations” is:
In-House Model: neatmail_model — our proprietary classification model built and maintained in-house (still under work)
which means, unless proven otherwise, you should assume that this is feeding the entire contents of your incoming emails not just to OpenAI, but also to this “Neatmail” company for processing with their “proprietary” model.
hard pass.








regardless of whatever else you think about AI, it’s a good idea to be very wary about security-sensitive apps that are written using LLMs.
there’s a self-hostable S3 replacement called RustFS, with development that leans heavily on LLMs.
they had a security vulnerabilty last year.
one LLM-written commit added a complete authentication bypass to the code. literally, you could just send
rustfs rpcas the auth token instead of an actual token.it was fixed in a pull request named fix: Prevent panic in GetMetrics gRPC handler on invalid input which claimed to fix a different auth problem and just coincidentally removed the hardcoded auth token.
security stuff is hard, and LLMs are prone to over-confidence. that’s a bad combo.
