Last updated 2026-09-02 · benchmark measured 2026-09-02 — deterministic & reproducible

Atlas is a native macOS editor built as a planning surface for coding agents.

Is Atlas production-ready?

Legit.Show scores Atlas 57 out of 100 — the simple average of its 5 measured frames. Legit.Show ran its deterministic 7-Frame production-readiness benchmark on Atlas (public-surface assessment), measured from the public surface with no LLM in the scoring path. Its strongest frame is Reliability; its weakest is Privacy. 5 of the seven frames returned a score; Performance and Accessibility were not measurable on this service and are recorded as null — not as zero. Every frame it averages is published with its evidence on the Legit.Show listing.
