A session on one key
⇧⌘R opens a tab straight into claude. The folder comes from the project, and the opening message you set is filled in with the project's name. With nothing configured it starts a bare claude and waits.
An editor you don't have to leave.
A small native macOS editor with a real terminal — and in the same window git, pull requests with review, Kubernetes, databases and an issue board. The things that otherwise send you to another app several times an hour are a tab or a pane here. And Claude Code or Codex runs in that terminal like any other process, with session history and a seat at the review.
One window
Each of these is a tab or a pane in the same window as your files. None of them opens another app, another sign-in or another account.
Claude Code and Codex, right at home
No chat panel and no API. The agent runs as a process in the same
zsh -l you would have started yourself — only in a
window that also holds the files, the diffs and git. Around that,
the editor does three things.
Resume in one click
The arrow beside ✦ lists the project's last eight sessions; ⌥⌘R opens the whole list as a searchable palette. The rows come from the transcripts in ~/.claude/projects — nothing is copied and nothing is sent.
Review over MCP
The editor is an MCP server named maya-editor: the agent gets the pull request's diff, code and threads, and its comments land in a draft that a person reads and submits. The agent never holds a token — the editor talks to GitHub.
Small and native
- 150–250 MB
- with four projects open, a terminal in each and a few files. Not a gigabyte.
- 77 ms
- to colour a half-megabyte file, off the main thread — highlighting with no parser, no tree-sitter and no JavaScript.
- 0
- web views. Even the Markdown preview is native text; the window chrome is the system's, not an imitation.
What it deliberately leaves out
LSP, autocomplete, a debugger, extensions, collaboration, remote development, a build system. That is not a list of things not done yet — it is a decision. You already know the editor that does all of it; this one is small on purpose.
Companies backing this
Nobody yet. The Company tier on GitHub Sponsors puts a logo and a link right here — where people deciding about the editor will see it.
How the licence works
30 days free
After downloading you sign in through GitHub and it runs for 30 days. The trial is counted on the server against your GitHub account, so reinstalling will not reset it — and it will not run down before you launch the app either.
Then for sponsors
It keeps running for anyone sponsoring mesour on GitHub. Private sponsorships work too — the question is asked with your own token.
Signing in happens in the browser
The app has no password field and must not have one. The whole sign-in runs at GitHub; only a signed licence comes back. What leaves your Mac is written up on one page, with the commands to check it.
Seven days offline
A licence is good for a week without a network. It is a deliberate trade: a longer window would mean a cancelled sponsorship taking longer to run out.
