What is RE2?
RE2 is a C++ library providing a thread-safe alternative to traditional backtracking regex engines like PCRE and Perl, prioritizing predictable performance and security over feature completeness.

The Vioscale score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for RE2, not the verdict.
