1Read each row as: "Above N PRs/month, paying Anthropic directly costs more than this vendor's flat seat." Below N, BYOK is cheaper on tokens alone.
2Per-PR token cost at 250 LOC = $0.0255math. Larger PRs (1,000 LOC migrations, vendored deps) push token cost up linearly.
3-Hidden BYOK costs not in the table: rate-limit retries on Anthropic 529s, key-rotation tooling, audit logging, per-developer key scoping. Budget ~10% overhead on the token total for ops.
4+Tools that genuinely BYOK today: Qodo, Bito, Macroscope, Git AutoReview, Claude Code Review (the last one IS the BYOK path because the seat base just covers the surface).
5-Tools that do NOT BYOK: CodeRabbit, Greptile, Codacy, Sourcery, Graphite Reviewer, Copilot Code Review, DeepSource, SonarQube, Snyk Code, Augment, Cursor BugBot. Token cost is theirs.
1You are 5 to 15 devs and want low ops burden. The 10% overhead is a person-week per year you do not have.
2Your security team needs a single SOC 2 / ISO 27001 surface to audit. BYOK splits the trust boundary.
3You want a vendor on the hook for review quality. BYOK shifts that to your prompt engineering.
