If you are weighing whether to build or buy AI review agents, Baz gives you the best of both worlds.
A model, a diff, and a prompt can get you a review. Scaling it takes consistent rules across agents, learning from developer feedback, visibility into every review, and models that balance quality and cost.
If you’re considering buying a reviewer, you don’t have to start all over. Baz builds on your existing standards, knowledge, and instructions with five layers of intelligence that keep reviews grounded in your expertise as you scale.
Incidents per PR rose +23.5% year over year as AI coding went mainstream (Cortex, 2026).

CoralogixBaz combines your skills, rules, and harnesses with its own and keeps review instructions current as your codebase evolves.
Baz reviewers also work with Claude, Codex, Cursor, and Devin through our MCP and plugins, steering the code while it's written, rather than after the PR opens.
Baz brings together codebase knowledge, engineering standards, ownership, developer feedback, and product intent across repositories. Reviewers draw on this shared context to assess each change’s wider impact.
Baz coordinates reviews, prioritizes findings, and learns from developers’ everyday PR reviews and comment responses. That feedback automatically informs future reviews.
Use Baz’s out-of-the-box commercial models, your own, or our specialized open-weight review model. Baz pairs reviewers with models that balance review quality with cost. Our specialized model draws on real developer feedback and findings engineers act on to deliver proprietary review intelligence.
Baz’s reports and dashboards give engineering leaders a shared view of review quality, developer engagement, and impact across teams and repositories.
Self-host Baz in your own cloud to keep sensitive data within your environment.
Move from feedback to resolution without starting over on every push. Baz keeps reviews focused as PRs evolve, so engineers spend less time sorting repetitive comments and more time preparing to merge.

Get feedback that becomes increasingly relevant to how your engineers work. Your team’s responses shape future reviews, so you can make reviews more useful without spinning up a separate workstream for prompt tuning.

Won't fix: our token lacks the scopes for that API (401), so search is intentional.View comment in PR #412
Do not suggest parallelizing writes that run once per organization.
Won't fix. Two small writes that run once per org; parallelizing gains nothing measurable.View comment in PR #388
Do not ask for separate disabled and hidden state tests when one render test covers both.
The render test already asserts both states. A second test would only duplicate it.View comment in PR #1204
Keep a consistent review bar as repositories and rule files multiply. Baz manages rule hierarchies and applies relevant standards, reducing the work of reconciling different agents’ interpretations of your guidelines.

Catch business-logic issues that look correct in the diff but break assumptions elsewhere. Baz investigates related code within the review’s scope, without pulling engineers into unrelated files or another team’s code.

Your model bill is only the starting point.

Not counted above: the engineering work to build the pipeline, evaluate its output, and keep it reliable as models and workloads change.
Engineering time to build, operate, and maintain the DIY reviewer is additional.
With usage-based tooling, the bill climbs as your team and PR volume grows. Baz is priced per seat, so more PRs and revisions don't add per-run charges. That's a budget you can forecast instead of one you watch all month.
See Baz pricingIllustrative scenario, not a measured customer average. Actual DIY costs vary by model, PR volume, context size, and review frequency.
If you run a single coding agent with a small rule set and modest PR volume, a homegrown reviewer may be all you need. These open source tools from the Baz team are free to use in your own setup.
Give your reviewer a head start with instructions drawn from real code review discussions. Find standards relevant to your stack and load them directly into your agents, skills, or harnesses.
Explore Awesome ReviewersRun more coding agents without weighing down your local machine. Gion fetches only the files each task needs, reducing local storage, token usage, and setup overhead. Best of all, Gion is Git compliant, so you can keep working the way you already are.
