Watch a pull request
get a litmus test.
This is a sample run, start to finish. Open a PR and Litmusly finds its preview deploy, sends a swarm of grounded reagents to walk it, and posts what they find in one comment. The content below is illustrative, not a real project.
From the commit you push to the comment on your pull request.
You open or update a PR.
Install the GitHub App once. After that, every pull request you open and every commit you push starts a review. Nothing else to wire up.
Litmusly finds the preview.
Using the GitHub Deployments API, it locates the preview build for the pull request. This works with Vercel and any host that publishes deployment statuses.
A swarm of reagents walks it.
Each reagent is grounded and opinionated. Every one walks the homepage and the primary call to action, then reports what helped and what got in the way.
One comment, edited in place.
Findings tagged blocker, friction, or nit land in a single comment. On each new commit the comment is edited in place, so the PR never fills with review spam.
One comment. Edited in place.
Below is a generic example of a single review comment, not a real project. Three reagents walked the homepage and the primary call to action. Here is what the PR ended up with.
The primary call to action is not keyboard reachable, so some visitors cannot reach the sign up flow.
On a narrow viewport the hero heading overlaps the navigation, which makes the main message hard to read.
The value proposition leans on internal terminology. It is not obvious what the product does within the first screen.
The call to action label and the page title describe the same action with different wording.
Across reagents, the highest impact issue is the keyboard trap on the primary call to action. Fixing it unblocks sign up for the widest group of visitors and should come before the smaller copy and layout notes.
Stops a visitor from completing the primary action.
Slows a visitor down or creates doubt, without fully blocking them.
A small, low risk polish item.
