dotbrave 0.1.0

Manage Brave as a dotfile: keyboard shortcuts, general settings (non-MAC keys), and force-installed PWAs from one TOML.

dotbrave

Manage Brave as a dotfile. Keep keyboard shortcuts, UI tweaks, and force-installed web apps in a single TOML, apply with one command, sync across machines — no Brave Sync required.

Status: alpha. Works on Linux, macOS, and Windows against Brave stable, beta, and nightly. Extracted from the multi-browser dotbrowser project as a focused, Brave-only tool with a flatter CLI (dotbrave apply instead of dotbrowser brave apply). Python 3.11+, standard library only.

Quick start

The repo ships an opinionated example config: vertical tabs collapsed to icons, decluttered new tab page, stripped-down toolbar, vim-style hjkl shortcuts. examples/all.toml bundles all three namespaces; shortcuts.toml, settings.toml, and pwa.toml are single-namespace variants.

Scaffold a starter config from scratch:

dotbrave init                # write commented template to stdout
dotbrave init -o brave.toml  # ...or to a file

Or apply the example directly from GitHub — no clone, no install. Fetched payloads are echoed with byte size + SHA-256 so you can see exactly what's being applied:

uvx dotbrave apply --dry-run \
  https://raw.githubusercontent.com/xom11/dotbrave/main/examples/all.toml

# Apply. If Brave is already running, dotbrave uses live apply;
# first-time live setup closes Brave normally and relaunches it once.
uvx dotbrave apply \
  https://raw.githubusercontent.com/xom11/dotbrave/main/examples/all.toml

Prefer to inspect / customise locally first? Download then apply:

curl -fsSL -o brave.toml https://raw.githubusercontent.com/xom11/dotbrave/main/examples/all.toml
# edit brave.toml ...
uvx dotbrave apply brave.toml

Anything you later remove from your config reverts to Brave's default on the next apply — no orphan entries.

Install

pipx install dotbrave     # global, isolated venv
uvx dotbrave <args>       # run on demand, no install step
pip install dotbrave      # into the active environment

Run from a branch: uvx --from git+https://github.com/xom11/dotbrave dotbrave <args>. Local dev: pip install -e ".[test]". Nix users: the repo ships a flake (nix run github:xom11/dotbrave).

Build your own config

A single TOML carries [shortcuts], [settings] and [pwa]. One apply writes all three in a single backup + write cycle.

# brave.toml
[shortcuts]
toggle_sidebar = ["Control+Shift+KeyE"]
toggle_ai_chat = ["Alt+KeyA"]

# vim-style hjkl
back                = ["Alt+KeyH"]
forward             = ["Alt+KeyL"]
select_previous_tab = ["Alt+KeyJ"]
select_next_tab     = ["Alt+KeyK"]

# Same chord on all OSes — Meta+ = Cmd on macOS, Super on Linux/Windows (auto-translated)
new_tab   = ["Control+KeyT", "Meta+KeyT"]
close_tab = ["Control+KeyW", "Meta+KeyW"]

[settings]
"brave.tabs.vertical_tabs_enabled"   = true
"brave.tabs.vertical_tabs_collapsed" = true
"bookmark_bar.show_on_all_tabs"      = false

[pwa]
# Force-installed Progressive Web Apps. Brave fetches each manifest,
# downloads icons, registers the app in chrome://apps, and emits a
# launcher (.desktop on Linux, app shim on macOS, Start Menu shortcut on
# Windows). Removing a URL + re-applying = uninstall.
urls = [
  "https://squoosh.app/",
  "https://app.element.io/",
]

dotbrave apply brave.toml --dry-run    # preview the diff
dotbrave apply brave.toml              # live apply if Brave is running

• Shortcut keys: Chromium KeyEvent codes joined by + — Control+Shift+KeyP, Alt+Digit1, F11. Meta+ is auto-translated to Command+ on macOS, so one config works everywhere.
• Setting keys: dotted paths into the profile Preferences JSON. MAC-protected keys (homepage, default search engine, pinned_tabs, …) are refused with a clear error — Brave would silently reset them on launch. Run dotbrave settings blocked to see what's protected.
• PWA URLs: every entry installs with default_launch_container = "window" and create_desktop_shortcut = true. [pwa] is the only namespace that needs elevated privileges: it writes a managed-policy file (sudo on Linux/macOS) or the Windows Registry (Administrator). No [pwa] diff → no elevation prompt.
• Empty header (e.g. [settings] with no entries) wipes everything dotbrave previously managed in that namespace. Missing header = skip the namespace entirely.

CLI reference

Shape: dotbrave [profile-flags] <action> [action-flags] [args]. Profile flags may be given before or after the action name — the after-action form wins when both are present. export is the inverse of apply: produce a round-trippable TOML from the current profile state.

Profile flags

Flag	Default	What it does
-r, --profile-root PATH	auto-detected	Brave's root profile directory.
-p, --profile NAME	Default	Profile directory name inside the root — e.g. "Profile 1".
--channel {stable,beta,nightly}	stable	Release channel; auto-detects the Brave-Browser-Beta / -Nightly profile path and targets the matching process.

Channel	Linux	macOS	Windows
stable	~/.config/BraveSoftware/Brave-Browser	~/Library/Application Support/BraveSoftware/Brave-Browser	%LOCALAPPDATA%\BraveSoftware\Brave-Browser\User Data
beta / nightly	same, with -Beta / -Nightly suffix	same, with suffix	same, with suffix

Snap and Flatpak installs (stable only) are probed automatically on Linux.

dotbrave apply -r /custom/path -p "Profile 1" brave.toml
dotbrave apply --channel beta brave.toml

Actions

Action	What it does
init [-o FILE]	Scaffold a commented starter TOML. Refuses to overwrite.
apply [-n] CONFIG	Apply [shortcuts] + [settings] + [pwa] from a file or HTTPS URL. -n/--dry-run previews the diff. URL fetches print size + SHA-256; pin with --expect-sha256 HEX; plain HTTP refused unless --allow-http.
export [-o FILE] [-a]	Emit [shortcuts] (only bindings that differ from Brave defaults; -a/--all-shortcuts lifts the filter) plus [pwa] as round-trippable TOML. [settings] is intentionally omitted — Chromium exposes no defaults table, so diff-vs-default is not computable.
restore [--list] [--from FILE] [-n]	Restore Preferences from a backup created by apply (most recent by default) and clear dotbrave sidecars. Does not touch [pwa] policy.
shortcuts dump [-a] [-o FILE]	Emit current bindings as TOML (default: only user-customised ones).
shortcuts list [FILTER]	List every bindable command name (substring filter).
settings dump [KEYS...] [-o FILE]	Dump managed keys, or explicit dotted paths.
settings blocked [-o FILE]	List MAC-protected keys apply will refuse, with current values.
pwa dump [-o FILE]	Emit currently force-installed PWA URLs as a [pwa] table.

Every action has detailed --help with safety notes and examples.

How it works

When Brave is closed, dotbrave patches the profile Preferences JSON directly. Each offline apply takes one timestamped backup, writes atomically (temp file + rename), and verifies the result by reloading.

When Brave is running, plain apply uses Brave's privileged UI APIs over a private loopback DevTools endpoint: ordinary settings go through chrome.settingsPrivate, New Tab settings through live New Tab UI actions, and shortcuts through the Settings CommandsService. Supported changes take effect without restarting. A Brave not yet carrying the endpoint closes normally and relaunches once; a setting without a live route falls back to the same normal-close + verified offline write. A config whose only diff is [pwa] skips the endpoint entirely — the managed policy is written while Brave keeps running, and Brave loads it at its next launch. The endpoint binds to 127.0.0.1 only, and there is no force-kill switch.

[shortcuts] and [settings] track managed entries in sidecar files (Preferences.dotbrave.{shortcuts,settings}.json), so removing a key from your config restores Brave's default on the next apply. [pwa] state lives in Chromium's managed-policy storage (Linux JSON file, macOS plist, Windows Registry) — the policy is the state.

On macOS, /Library/Managed Preferences/ is a system-managed cache that gets reclaimed at boot on non-MDM machines, which would otherwise uninstall your PWAs. To keep them installed, apply installs a small root-owned self-healing helper:

• /Library/LaunchDaemons/org.dotbrave.com.brave.Browser.pwa.plist — watches the managed-preferences directory and rewrites the policy if macOS removes it.
• /Library/Application Support/dotbrave/com.brave.Browser.managed.plist and com.brave.Browser.heal.sh — the policy source of truth and the rewrite script.

Applying an empty [pwa] table (urls = []) removes all of the above.

Brave install methods

Install	Auto-detected	[pwa] works	Notes
.deb / .rpm / Arch / NixOS	yes	yes	Reference install; full support.
Snap	yes	refused with clear error — sandbox doesn't read /etc/brave/policies/managed/	Use .deb for [pwa].
Flatpak	yes	refused with clear error — same sandbox limitation	Relaunch goes back through flatpak run.
macOS .dmg	yes	yes	Includes cfprefsd cache invalidation + self-healing daemon.
Windows installer	yes	yes — writes HKLM\Software\Policies\BraveSoftware\Brave; requires Administrator

Coming from dotbrowser?

dotbrave is a standalone extraction of dotbrowser's Brave support with its own state names: sidecars are Preferences.dotbrave.*.json (was Preferences.dotbrowser.*.json) and the macOS daemon is org.dotbrave.<bundle>.pwa (was org.dotbrowser.<bundle>.pwa). Your Brave profile itself is untouched by the switch, but entries previously managed by dotbrowser are not tracked by dotbrave until you apply your config once with dotbrave. On macOS, remove dotbrowser's daemon (dotbrowser brave apply with an empty [pwa] table, or the manual launchctl bootout steps in its README) before letting dotbrave manage [pwa], so two daemons don't fight over the same plist.

Caveats

• Brave Sync can overwrite [settings] entries on its next pulse if they fall in a synced category. UI-layout keys like brave.tabs.vertical_tabs_* are local-only and immune. apply prints a non-fatal warning when sync.has_setup_completed=true.
• A handful of settings (homepage, default search engine, pinned_tabs, …) are integrity-protected and refused rather than silently reset by Brave on next launch. Set those in the Brave UI.
• [pwa] is force-install (Chromium's enterprise WebAppInstallForceList). Apps appear in chrome://apps with an "Installed by your administrator" label and hidden right-click Remove — uninstall by deleting the URL from [pwa] and re-applying. That is the right semantics for dotfile-style management (the TOML is the source of truth), but worth knowing if you also install PWAs by hand.
