In the know, not just in the loop.
Parbuild turns Linear tickets into a steady stream of small, refactor-first pull requests on trunk — each one small enough that your team actually understands it.
Sign InApproving isn't understanding.
Most AI coding tools keep you in the loop: they hand you a sprawling diff and ask for a thumbs-up. You click approve, and you understand your codebase a little less than before. Parbuild is built so every change it makes is one your team can hold in their heads.
How it works
Refactor first, then change
Before a feature or a fix, Parbuild makes the change easy: a behavior-preserving refactor that ships as its own PR. Then it makes the easy change. Your codebase gets cleaner as features land.
One behavior per PR
Every pull request does one thing you can describe in a sentence. Reviews take minutes and get real attention, not a rubber stamp.
Trunk-based by default
No long-lived feature branches, no big-bang merges. Small changes land on main one after another, each going through whatever CI you already run.
Plans as it goes
Instead of a big upfront plan that's stale by PR three, Parbuild picks the next right-sized step based on what has actually landed.
From ticket to trunk
- 1
Write the ticket in Linear
Describe the feature or fix the way you already do.
- 2
Parbuild researches
It reads your codebase and the ticket, and writes the approach back into the ticket.
- 3
It plans the next step
A small sub-ticket appears in Linear — one behavior, one sentence.
- 4
It opens a focused PR
Built in an isolated sandbox, then reviewed by Parbuild right on the PR — in the open, so you can read the review and respond to it too.
- 5
Your team decides
Merge it, or leave feedback and Parbuild picks up where it left off. Then on to the next step.
Works where you already work
Tickets and progress live in Linear. Code lives in GitHub pull requests. Every run links to a live view of what the agent is doing. Nothing merges without your team.
