GitHub Copilot expanded from code completion to code review, then to an agentic multi-angle reviewer (March 2026) with cross-file dependency tracing and persistent memory. 60M+ reviews processed, actionable feedback in 71% of cases. Strong on integration and context; lacks BYOK, self-hosting, and failure scenario simulation.

Copilot is deeply integrated into GitHub and genuinely improved in 2026 — agentic cross-file analysis, memory, diagrams. Argus's remaining edges: failure scenario simulation, BYOK so you control model and cost, first-class scenario memory (not just static repo knowledge), and a Glass Box footer that shows the review contract, what was checked, and what was suppressed. Worth using together — Copilot for its GitHub-native surface, Argus when you need deeper review on critical paths.
