Parameters

Parameter	Default	Description
username	required	GitHub username
theme	dark	dark or light
mode	PR list	repo-aggregate to group by repository instead of listing individual PRs
status	all	Filter by status: merged, upstream, open, draft, closed, or comma-separated

limit	10	Max rows to show
sort	status,stars_desc	Sort fields, comma-separated (see below)
fields	all columns	Columns to include, comma-separated (see below)
stats	all	Which summary stats to show in the header bar

Status values

Status	Meaning
merged	PR was directly merged on GitHub, or closed by a cherry-picked commit
upstream	PR was closed because a maintainer pulled the changes into their own PR or via an external tool (Gerrit, Phabricator) — contribution accepted but not directly merged
open	Still open
draft	Open as a draft
closed	Closed without the changes being accepted

Both merged and upstream count toward the merged tally and merge rate.

Caching

In-process sync.Map keyed by the request query string. Entries never expire; once an entry is older than 12h, the next request serves it immediately and triggers a background refresh from GitHub. This keeps responses sub-millisecond after the first cold fetch, which matters for embedders like GitHub Camo that enforce short fetch timeouts.

Deployment

The repo includes a Dockerfile and fly.toml for deploying to Fly.io.

fly apps create pullscape
fly secrets set GITHUB_TOKEN=your_token_here
fly deploy
