bleeding edge

bleeding edge — Bleeding edge means the very newest technology, so new that it may still be unstable or risky to use.

In simple English

"Bleeding edge" goes one step beyond "cutting edge". Cutting-edge tech is new and impressive; bleeding-edge tech is so new that early users may "bleed": hit bugs, missing docs and breaking changes. Engineers use it when choosing tools: "That framework is bleeding edge; let's wait for a stable release." It can be praise or a warning.

How to say it: Stress "BLEED": "BLEED-ing edge".
