LoupePull requests
Files with a syntax-highlighted diff, unified or split, with a tree you can filter and mark as viewed. Review threads, suggestions, and the merge box live in the same tab.
Open source · AGPL
GitHub reviews and Linear issues, in one fast desktop app.
Loupe shows the pull requests waiting on you, the issues they close, and the CI behind them in one native window. Tabs, a command palette, and the keyboard first.
Yours from the first launch.
Your tokens stay on your machine
Loupe talks to GitHub and Linear straight from your computer. Tokens live in the macOS Keychain or in your Linux config folder.
Open source
AGPL license: read the code, audit it, build it yourself, and contribute.
macOS and Linux
A native app built in Rust with GPUI. Apple silicon and x86_64 Linux builds, updated in place.
No account with us
There is no Loupe server and nothing to sign up for. Sign in to GitHub and add a Linear key.
What changes in your week.
The four things you do between commits, without a dozen browser tabs.
Triage the inbox
GitHub notifications filtered by organization, repository, or kind, and cleared in bulk.
Review a pull request
Conversation, files with a highlighted diff, and checks in one tab. Comment, approve, or request changes.
Move a ticket
Your Linear board next to the pull request that closes it. Change the status, assignee, or labels in place.
See the CI
Every check of a pull request, the workflow run behind it as a graph, the log of the step that failed, and Re-run.
Everything a review needs, a keystroke away.
Checks
Every check of the head commit, which ones are required, how long each took, and a link to the job.
Actions
A workflow run as the graph of its jobs and matrices, with its annotations, artifacts, and Re-run.
Linear
Team boards, your issues, projects, and saved views, across several workspaces. Each pull request shows the Linear issues it closes.
Command palette
Cmd+K jumps to any pull request, repository, issue, or screen. Narrow it with pr:, repo:, org:, or issue:.
Themes
Six themes, each with a light and a dark palette, switched live, plus contrast and density.
Review with T3 Code
Connect a T3 Code server and hand a pull request to it: Loupe writes the review request, picks the project that tracks the repository, and the server starts the review thread in a worktree of the pull request's head.
The review request Loupe writes
- Read the repository's AGENTS.md, the description, and the reviews so far.
- Check that it solves what it claims, against the linked Linear issue.
- List findings with file:line, severity, and a proof.
- Run the tests it touches and show a mutation that fails one.
- Say what leaked out of scope. Never comment, approve, or push.

Is Loupe free?
Yes. Loupe is free software under the GNU AGPL v3.0. There is no paid plan.
Where do my tokens go?
Only to the API they belong to: GitHub tokens to GitHub, Linear keys to Linear, the T3 token to your T3 server. Loupe has no server of its own and collects no analytics.
Which GitHub permissions does it need?
Sign in with the device flow (scopes repo, read:org, and notifications), paste a personal access token, or let Loupe use the token of the GitHub CLI.
Do I need Linear?
No. Without a Linear key you still get Reviews, the Inbox, pull requests, and Actions. Linear adds boards, issues, and the issues each pull request closes.
Windows? Intel Macs?
Not yet. Releases are built for Apple silicon and x86_64 Linux. You can build from source on other platforms GPUI supports.
What is T3 Code?
An open-source server that runs coding agents in threads. Loupe can start a review thread on it for a pull request; everything else works without it.
