The engineers have spoken

Arcen is different.It catches what matters and stays quiet about the rest.

 "We merged a PR that introduced a SQL injection vulnerability. Arcen caught it in 90 seconds. Our entire security team had missed it in review. That was the moment we stopped treating it as a nice-to-have."

"We were skeptical. Our senior engineers had tried AI review tools before and found them noisy — lots of findings, most not worth acting on. Review felt like a ritual, not a safety net."

"Junior developers on our team used to wait days for feedback. Half the comments were nitpicks. Arcen gives them a full review before a senior engineer even opens the PR — they ship faster and learn more."

Questions we get asked a lot

Yes. Forever. No time limit, no credit card, no bait and switch. Solo developers get 50 PR reviews per month on us permanently.

Copilot suggests code as you write. Arcen reviews finished code before it merges. Different problem, different solution. They work well together.

Javascript, Typescript, Python, Go, Rust, Ruby, Java, and PHP. More on the way — check our changelog for updates.

Most PRs are reviewed within 90 seconds of opening. Larger PRs with 500+ lines may take up to 3 minutes.

No. Arcen runs its own models on dedicated infrastructure. Your code never touches OpenAI, Anthropic, or any third party model provider.

Yes. No contracts, no cancellation fees. Cancel from your dashboard in two clicks.

The changelog
is always open.

We update Arcen every week. The changelog is public, detailed, honest — including when something doesn't work as expected. It's the fastest way to see whether this is a project people are serious about.
