The problem with these kind of tools now is that Codex is so good you can basically build something which is good for 99% of cases in a single day, and it's free...
Look at Tobi vibe-coding QMD, he's not a full-time engineer and vibed that up and now it's used as the defacto RAG engine for OpenClaw.
Yeah QMD is quite impressive! The main difference between us and them is the scale folks would be looking at indexing. The serverless ingestion engine I described in the post is optimized for processing large batch jobs with high concurrency. We depend on a lot of cloud compute for this which isn't something QMD's local-first environment is optimized for. That said, it's a great option for OpenClaw!
