Forge

Every file,
one window.

Forge is a writing app for the Mac that opens your whole folder. Markdown reads like a page, and code, spreadsheets, PDFs, Word files and slide decks sit beside it as tabs. Everything stays a plain file in a folder you chose — and when that folder is a git repository, Forge commits and syncs it for you.

Mac App Store Requires macOS 26 or later

The Forge window: a project's folders on the left with git status dots, tabs along the top, and a Markdown launch plan with a chart, a table and a checklist rendered in the editor. — Your folder on the left, your files as tabs, and Markdown that reads like a page.

What it
does

Markdown that reads like a page

Headings, images, tables, task lists, quotes, code blocks and footnotes render as you type, and the syntax steps aside until your cursor needs it. Underneath it is still a plain .md file that any other app opens unchanged.

Every file in one window

Code in twenty-odd languages with syntax highlighting, CSV and TSV as an editable grid, JSON with its structure laid out. Word documents, PowerPoint and Keynote decks, PDFs and images open as tabs too — right where you were.

Your folder, not a library

Forge opens a folder you already have — in iCloud Drive, Dropbox, anywhere — and shows it in the sidebar. Quick Open jumps to any file by name. Nothing gets imported, renamed or locked away.

Git without the terminal

Changed files get a dot in the sidebar. The Changes panel lists them; write a sentence and press Commit & Sync. If someone else changed the same lines, Forge backs out the merge and keeps your work committed, instead of leaving conflict markers behind.

GitHub, signed in once

Sign in with GitHub with a short code, then open any repository as a folder: Forge clones it and keeps it in sync. Your token lives in the Keychain and renews itself.

An outline for anything

The outline sidebar follows whatever is open: the headings of a document, the keys of a JSON file, the slides of a deck. Click to jump; fold sections in the editor to focus.

Export and print

PDF, HTML and Word, with headers and footers you set once. Every save is a version you can browse and restore.

Images where you want them

Paste or drop an image and it’s saved next to the document as an ordinary file — or, if you prefer, uploaded to your own S3-compatible bucket, per document.

Private by design

Forge runs in the macOS sandbox with no Forge account, no analytics and nothing phoning home. It talks to the internet only for what you set up: GitHub, your bucket, and images a document links to.

Forge's Changes panel in the sidebar: two changed files with status dots, a commit message, and the Commit & Sync button. — The Changes panel: what changed, one sentence about it, Commit & Sync.

A JSON file in Forge with syntax highlighting, and its structure laid out as an outline in the sidebar. — JSON with its structure in the outline, keys and types at a glance.

A Markdown launch plan in Forge with a chart, a table and a checklist, next to the project's folders. — Markdown with images, tables and task lists, still a plain `.md` file.

What it asks for,
and why

Forge opens the files and folders you choose. When a document you opened on its own shows images or links from the folder around it, Forge asks once for access to that folder and remembers your answer. If you sign in with GitHub, your token goes only to GitHub; if you set up an S3 bucket, images go straight from your Mac to it. Both are stored in your Keychain. Nothing else leaves your Mac. The details are in the privacy policy.
