Is LeanCTX production-ready?

Legit.Show scores LeanCTX 87 out of 100 — the simple average of its 5 measured frames. Legit.Show ran its deterministic 7-Frame production-readiness benchmark on LeanCTX (public-surface assessment), measured from the public surface with no LLM in the scoring path. Its strongest frame is Privacy; its weakest is Security. 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.

The 7 Frames

• Performance — not measurable on this service (null — not scored as 0)
• Accessibility — not measurable on this service (null — not scored as 0)
• Security — 60/100
