One screen. The entire review.

Read, comment, approve, manage reviewers and merge — all in one window.

@@ 01 · the agent firehose @@

Review your agent's code before it's a PR.

Your agent just wrote four hundred lines. Read them on your own branch — before they ever become a pull request.

Understand it before you ship it.

@@ 02 · the whole job, one window @@

Everything a review needs. Nothing it doesn't.

Read the diff. Leave comments. Approve, request changes, manage reviewers, and merge — without bouncing to github.com.

The review starts and ends in Pier.

Your code stays on your machine.

Pier has no server. It talks straight to GitHub from your computer — nothing sits in the middle, nothing is stored, nothing is indexed.

The most private place to review code is the one with nothing between you and it.

A handful of screens. Each does one thing.

No settings maze, no empty dashboards. Keep scrolling — they slide past one by one.
