§ The result
Coderbyte leads XOR on all 7 criteria.
Coderbyte, filed under Assessment, comes out 12 points above XOR, filed under Screening: 42 against 30 under rubric v1.0. Coderbyte takes all 7 criteria and XOR none of them; the nearest contest is Bias Audit Transparency, Coderbyte 20 to XOR 18. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (Coderbyte 44, XOR 20, 20% weight), but it accounts for only 38% of the weighted advantage Coderbyte holds across the 7 criteria on that side of the table.
Vendor profile
Coderbyte
Coderbyte is a technical hiring platform offering coding assessments with automated and AI grading of challenges and take-home projects, live coding interviews, and AI screening that grades resumes against job-description criteria and runs agentic phone screens.
Vendor profile
XOR
XOR is a text-first conversational-AI recruiting platform that pre-screens and scores high-volume and hourly candidates with recruiter-defined knockout/scoring questions over SMS, WhatsApp, and Messenger, then auto-schedules interviews on the recruiter's calendar.
§ The record
Coderbyte is filed under Assessment AI, XOR under Screening AI. They record no secondary category in common.
Both are in scope of NYC LL 144, Illinois HB 3773, EU AI Act and Colorado AI Act. Only Coderbyte is in scope of Mobley v. Workday.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +12.5 — the difference between the two totals before either is rounded. Shares are of 12.5 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +12 beside that +12.5.
§ Category-by-category
Raw score per criterion, with weighted delta.
Δ is Coderbyte minus XOR.

§ Evidence
Cited sources and documented absences, criterion by criterion.
An absence is a finding, not a blank: the reviewer looked for a named artefact and recorded that it is not located. Where a source sits is a fact about hosting only.
