We've launched Merge on ProductHunt!

Your engineers are reviewing more code than ever before.Merge lets you assess for it.

With Merge, candidates review a PR, just like on the job. Then, our AI agent addresses PR comments in realtime, simulating a real engineer.

Platform

A complete review signal,
from invite to hiring decision.

Merge turns code reviews into an assessment involving real engineering work to produce hiring-ready signals.

Review Loop

See how engineers handle code after the first read.

Candidates enter a small, realistic codebase with a pull request that is scoped enough to understand quickly.

Candidates read a realistic PR and comment on correctness bugs, refactors, and vulnerabilities.

Candidates submit their comments so Merge can evaluate their priorities before generating a response.

Merge addresses candidate comments and opens a fresh PR revision so reviewers can evaluate the next state.

The loop continues until time expires or candidates feel the code is ready to approve.

Custom Assessments

Calibrate every assessment to the role you're hiring for.

Difficulty

Match the bar to interns, new grads, mid-level engineers, or senior staff candidates.

Specialization

Focus the work on frontend, backend, infrastructure, security, or platform engineering.

Languages

Restrict to a few languages for depth or allow broad stacks for generalist hiring loops.

Reporting

A scorecard your hiring team can actually discuss.

Every report connects candidate comments to code quality, risk detection, revision judgment, and practical hiring recommendations.

Token Use & Efficiency

See exactly how efficiently candidates work with AI.

Merge is the first assessment platform that shows exactly how efficient a candidate is with token use, estimated cost, and PR revisions.

Assess the engineering work your team actually values.

Merge gives candidates a real review loop and gives your team evidence that is easier to trust than another algorithm quiz.
