Autonomous code review

Stop the review backlog.

Hound watches every pull request. It learns your team's patterns, flags logic bugs before they ship, and keeps code quality consistent across the entire stack. Without the bottleneck.

Animated demo of Hound reviewing a pull request Hound PR review demo
Hound flags half the issues our senior reviewers used to catch the next morning. By the time I open a PR it's already been read.

Alex R. — Staff Engineer, fintech startup

It caught an unauth'd code path a human reviewer had missed three times. That's the review we always wanted.

Maya T. — Engineering Lead, B2B SaaS

Our four backend engineers write differently; Hound reads all four like one reviewer. PRs ship without the back-and-forth.

Jordan K. — CTO, dev tools

PR diff viewed by Hound

Hound reads every PR line-by-line

Every time a PR opens, Hound reads the full diff and the surrounding codebase context — cases humans miss because they only skim.

PR with Hound review comments

Engineers get blunt, actionable feedback

A structured review comment lands on the PR — bugs, security gaps, test holes — each with a fix, not just a label.

"Every team has a senior engineer bottleneck. The best engineers spend hours on PR reviews instead of building. Hound fixes that."

47% of engineering time goes to review and rework
8x review throughput vs manual process
0 PRs that slip through without review

Catch what humans miss

N+1 queries, race conditions, unvalidated edge cases — the bugs that live in the seams between files. Hound reads the whole codebase, not just the diff.

Never miss a PR

Hound watches every repo, 24/7. When a PR opens, it reviews it immediately — before the team even looks. Early feedback prevents late surprises.

Learns your team's style

No two teams write the same. Hound builds a model of your conventions, naming patterns, and risk areas. The longer it runs, the sharper the feedback.

Full context, not just diff

Hound indexes your entire codebase. It can tell you whether a function is called elsewhere, whether a change breaks an internal API, and whether the tests actually cover the new behavior.

1

GitHub PR opens

Hound receives the webhook the moment a PR is opened or updated. No manual trigger needed. No GitHub Actions config required.

2

Hound analyzes diff in context

It reads the full diff, traces dependencies across the codebase, and cross-references with your team's review history. It knows what "good" looks like here.

3

Review comment posted

Hound posts a structured review comment directly on the PR — flagging bugs, style issues, security concerns, and test gaps. Every finding is explained, not just labeled.

4

You decide. Hound learns.

Hound tracks whether its feedback is accepted, dismissed, or causes a discussion. That signal feeds back into the model. Each review makes the next smarter.

Coverage across the Git platforms and dev tools your team already runs.

Use cases

First-pass review, before any human reviewer opens the tab.

Early-stage startup engineers

Five engineers shipping daily, but PRs sit for hours waiting for whoever isn't in standup.

A first-pass review lands in seconds so your seniors review diffs instead of doing triage.

Platform / reliability teams

Every platform PR needs a safety review before it touches master, and the queue is the bottleneck.

Reads the diff against your team's standards and flags risky paths before any human reviewer opens the tab.

Open-source maintainers

Contributors ship PRs at 2am; you review them at 9am and the queue is overwhelming.

Triages every PR up front so the first thing you see is already the parts that need a human.

Common questions

What does "learns your team's style" mean?

Hound reads your existing PR history and codebase conventions during setup. It then applies your naming patterns, architectural preferences, and review style — not generic advice.

Do I need a team minimum?

No. Single seats are fine. Pricing scales with your actual team size.

How does it integrate with GitHub?

Install the Hound GitHub App on your organization or personal account. Authorize the repos you want reviewed. That's it — no webhook configuration required.

Can I cancel anytime?

Yes. Monthly billing, cancel whenever. Your data stays accessible for 30 days after cancellation.

Code review is not a human's best use of time.

Let Hound handle the first pass. Your senior engineers focus on what only humans can do.

The five things trial visitors ask first.

How is Hound priced?
Flat $20 per user per month, billed monthly. No per-review add-ons, no usage caps, no seat minimums — a single engineer on a personal repo pays the same flat rate. Cancel any time, no annual lock-in.
What languages and frameworks does Hound support?
Hound operates on the GitHub diff and repository tree, not on a parser tied to one language. TypeScript, Python, Go, Rust, Ruby, Java, C#, PHP, Swift — if it ships to GitHub, Hound reviews it. The "learns your team's style" pass reads whatever stack you actually write.
What happens to my code and PR data?
Code is read by the review model only for the active PR and is never used to train shared weights. Review history lives in your account, retained for 30 days after cancellation, and exportable on request. We do not share diffs, repo contents, or review text with third parties.
How long does setup actually take?
About three minutes: install the Hound GitHub App on your org or personal account, pick the repos you want reviewed, and you're done. No webhook configuration, no CI edits, no YAML. The first review lands on your next PR — usually within one cycle.
How is Hound different from Copilot, Cursor, or generic AI reviewers?
Copilot and Cursor are pair-programmers that autocomplete code as you type. Hound is a first-pass reviewer: it posts structured findings with severity and a concrete fix on the PR itself. It learns your team's conventions from your history instead of giving generic advice, so the review sounds like another engineer on the team — not a linter with a personality.
