14 buyer-side questions on AI code review tools, answered with the source URL in the magenta pin. Bundled Copilot Code Review is free at the seatsrcbut consumes AI Credits per review since June 2026. Per-question detail below.
1Is GitHub Copilot Code Review free if I already pay for Copilot?
At the seat level, yes: Copilot Code Review is bundled in Copilot Business ($19/user/mo) and Copilot Enterprise ($39/user/mo). Since 1 June 2026, individual reviews now consume AI Credits, and overage above the included allotment bills at list.
2What is the cheapest AI code reviewer for a 10-developer team?
Two tools price the whole team rather than the seat, and they win at this size: Augment Code at $20/month flat for up to 50 seats, and Git AutoReview at $12.49/month annual for up to 25 members with your own model key. On per-seat pricing the cheapest published rates are Sourcery at $12/dev/mo and Bito Team at $12/seat/mo annual. SonarQube is not comparable per seat at all: its Team plan is metered on private lines of code from $34 a month for up to 100k LOC, and is free forever below 50k LOC, so a ten-developer team on a small codebase may pay nothing. Whether any of them fits depends on your Git platform and deployment posture. Run the calculator.
3Can AI code review tools run fully on-prem?
Yes, but the list is short: Qodo, Snyk Code, SonarQube Server, Diffblue Cover, Bito on Enterprise, and DeepSource Enterprise which publishes an airgapped deployment option. Most others are SaaS-only or require an outbound connection even on a self-hosted install. Augment Code publishes no self-hosted, VPC or on-prem option at all.
4Do AI code review tools replace human reviewers or augment them?
Augment. As of mid-2026, every published vendor still treats AI review as a pre-merge filter that a human still signs off on. Vendors that claim 'replaces human review' are exaggerating.
5What is the difference between SAST and AI code review?
SAST (SonarQube, Snyk Code, DeepSource) runs rule-based pattern matching. AI code review (CodeRabbit, Greptile, Claude Code Review) generates prose comments that explain the reasoning. The two stack: SAST catches the known, AI catches the novel.
6Does CodeRabbit work on GitLab and Azure DevOps?
Yes. CodeRabbit supports GitHub, GitLab, Bitbucket and Azure DevOps with first-class PR/MR integration.
7What does Cursor BugBot really cost?
There is no published BugBot price any more. Cursor retired the $40 per seat per month BugBot subscription in its 11 May 2026 post, effective at each customer's first renewal after 8 June 2026, and moved BugBot to usage-based billing: Individuals draw on the usage included in a paid Cursor plan, Teams bill it from on-demand spend. Cursor publishes an average run cost of $1.00 to $1.50 depending on PR size, which is an average rather than a rate. The $40 still on the rate card is the Cursor Teams seat, not BugBot, and the plan is Teams, not Business.
8How does Claude Code Review price?
Through a Claude plan seat that already includes Claude Code, not a separate product price. Anthropic publishes Team at $20/seat/mo annual ($25 monthly, 2-seat minimum) for a standard seat and $100/seat/mo annual ($125 monthly) for a premium seat with 5x the usage, with Pro at $17/mo annual for individuals. Enterprise is $20/seat/mo annual and is the tier that explicitly adds usage at API rates on top, which is where $/PR starts scaling with PR size.
9What is BYOK and which tools support it?
BYOK = bring your own LLM key (Claude / Gemini / OpenAI) so token cost is paid directly to the model vendor. Today: Qodo, Macroscope, Git AutoReview (every plan, including the free one), DeepSource (Enterprise Server only), and Claude Code Review (which IS the BYOK path). Bito publishes bring-your-own-key language for Governor, its model router, but not for its AI Code Reviews plans.
10How much does an AI review cost in tokens at Claude Sonnet 4.6 list?
Roughly $0.025 per PR at 250 LOC. Inputs run 24 tokens per LOC (PR context inflates), outputs run 2 tokens per LOC.
11Are accuracy benchmarks like OpenSSF or SWE-bench usable for vendor selection?
As directional signal, yes. As a ranking column, no. Numbers move per release; a static snapshot misleads. We point at the leaderboards but do not roll them into a 'score'.
12What changed in AI code review pricing in 2026?
Four big moves. (1) Claude Code Review launched Mar 2026 on the Claude plan ladder, where Claude Code is included from the $17/mo Pro seat and the $20/seat/mo Team standard seat upward, with the $100 premium seat buying 5x usage. (2) GitHub switched Copilot from flat premium requests to AI Credits on 1 Jun 2026. (3) Cursor retired the $40 BugBot seat and moved it to usage-based billing, effective at renewals after 8 Jun 2026. (4) Seats moved up across the board: DeepSource from $12 to $24 per user/month billed yearly, Qlty from a $10 Team seat to $20/contributor/mo annual, Graphite Reviewer to $40/user/mo annual, and Macroscope v3 from $18 to $22/dev/mo. Augment Code went the other way, dropping the $50 seat for a $20/month flat team price.
13Does Copilot Code Review work on Azure DevOps?
Yes, on Azure DevOps Repos with the Copilot Business or Enterprise tier. Azure DevOps Server coverage lags GitHub on Azure DevOps Services.
14When is BYOK genuinely cheaper than a managed reviewer?
Above the per-tool breakeven on /byok-breakeven. For most 10-dev teams at 50 PRs/wk, BYOK undercuts managed once monthly PR volume passes the high single-thousand mark. Add ~10% ops overhead before comparing.
