Launched today. Koalr — deployment risk scoring for every PR, before it merges

Hey everyone Andrew here, founder of Koalr. We just launched.

Koalr scores every pull request 0 100 for production risk before it ships. It uses 36 research based signals things like file change blast radius, author expertise drift, CODEOWNERS violations, CI history, and time-of-week patterns to flag risky deploys before they become 2am incidents.

It connects to GitHub in minutes, no code access needed we only read metadata.

I'm Andrew, founder of Koalr — AMA about what actually predicts production failures

Hey PH

I'm Andrew, founder of Koalr a deployment intelligence platform that scores every PR 0 100 for production risk before it merges.

The idea came from 20 years in IT consulting and delivery. I've sat in more post-incident reviews than I can count, and the pattern is almost always the same: someone merged something on a Friday, nobody flagged it, and the team spent the weekend firefighting. The data to catch it was there it just wasn't connected.

So I built Koalr.

Koalr - Predict deployment failures before your PR merges!

Koalr is the Deployment Intelligence™ Platform — we score every one of your PR's 0–100 using 36 research validated signals before you merge. Predict & prevent production incidents before they happen.

Vote selling on Product Hunt

Every day, after launching, makers are contacted on LinkedIn and X by people offering to sell votes. As the Product Hunt team, we are very much aware of this and really hate it. We have systems in place to neutralize this type of gaming. Every vote counts for a different number of points on Product Hunt. A couple examples:

  • An account with a recently created gmail address and no history of quality contributions on Product Hunt: this vote will count for 0 points. Yes, this might be a well intentioned user, but we take a conservative approach to protect the community. If the account has a company email or applies for verification on Product Hunt, that's a different story.

  • An account with a company email address linked to a legitimate LinkedIn account with a history of meaningful contributions on Product Hunt: this vote carries significant weight.

A couple questions for the community:

  • Are there specific accounts on Product Hunt that you suspect participate in vote selling? You can reply here or email report@producthunt.co

  • What would you want to see us do differently here?

What signals do you actually check before merging a high-stakes PR?

Most teams have an informal mental checklist PR size, who wrote it, whether tests passed, time of day. But it's rarely written down, and it varies by person.

Curious what signals matter most to your team before you merge something you're nervous about. Is it coverage? CODEOWNERS sign-off? Who's on call? Something else entirely?

We let Claude write 100% of our code for 7 days. Here's what broke first.

Last week we did something stupid.

We paused all human coding. Gave Claude (Anthropic) access to our GitHub repo. Told it to build new features, fix bugs, and ship.

No human review. No guardrails. Just Claude and our codebase.

For 7 days, it ran the engineering team.
