Pricing: Unlimited vs Per-Review
Anthropic charges $15-25 per review depending on PR size. For a team doing 10 reviews per week, that's $600-1,000/month.
DiffSwarm charges $14.99/mo flat for unlimited reviews. You pay your AI provider directly for tokens at their standard rates -- no markup.
The BYOK model means you use your existing Claude Code or Codex subscription. If you already pay for Claude Code, DiffSwarm just adds $14.99/mo on top.
Privacy: Local vs Cloud
DiffSwarm runs 100% locally. Your code never leaves your machine. Only entitlement checks hit DiffSwarm servers.
Anthropic's Code Review processes your code in their cloud infrastructure.
For companies with strict IP policies, local execution is a hard requirement. DiffSwarm gives you that without compromise.
Availability: Everyone vs Enterprise
Anthropic's Code Review is only available for Claude Team and Enterprise customers (as of March 2026). Individual Pro and Max subscribers cannot use it.
DiffSwarm works for anyone who has Claude Code or OpenAI Codex CLI installed. No enterprise contract required.
Solo developers, small teams, and startups get the same review quality as large organizations.
Security: Dedicated vs General
DiffSwarm has a dedicated Security Audit mode with OWASP Top 10 categorization, CWE tagging, and severity-aware findings.
Anthropic's Code Review provides general code review that may catch some security issues, but doesn't have a dedicated security focus.
When you need to verify that a PR doesn't introduce auth bypasses, injection vectors, or misconfigurations, a purpose-built security mode matters.
Multi-Agent Verification
DiffSwarm uses multiple specialized agents -- bug finders, security scanners, verifiers -- that propose and then verify findings. A configurable confirmation quorum ensures low false-positive rates.
Anthropic's Code Review uses a multi-agent approach, but DiffSwarm's explicit hypothesis-verify cycle and cross-card synthesis provide deeper analysis. Each finding is challenged before it reaches your report.
The result: fewer noise findings, more actionable bugs. You spend time fixing real issues instead of triaging false positives.
