Private by default
No telemetry, no forced account, and nonpersistent browsing storage in the current build.
Nimlo 0.7 for Apple Silicon
Download the macOS edition.
Try the current Nimlo app bundle as a DMG for Apple Silicon Macs. This is an experimental release, not a production browser replacement.
Requires macOS 15 (Sequoia) or newer. Built for M-Series arm64 Macs.
The web deserves more than two choices.
Modern browsers are powerful, but they have also become enormous platforms for ads, accounts, tracking, growth systems, and features many people never asked for.
Nimlo starts small on purpose: a quiet browser shell built in Zig, using the system WebView today while growing user-owned browser features around it over time.
Built for user control.
Small enough to understand
The first goal is a readable browser shell with clear boundaries between app, tabs, WebView, and storage.
Useful before it is huge
Nimlo does not try to replace the whole browser engine first. It ships a usable shell and deepens from there.
Roadmap.
Nimlo is not a production browser yet. The roadmap starts with a small, reliable shell and then builds local-first browser features around it.
First Window
Launches as a macOS app, opens a desktop window, embeds WebKit, loads the start page, and accepts typed URLs.
Basic Browser Controls
Address bar, back, forward, reload, stop, and page title updates are in place for everyday navigation.
Tabs
Nimlo supports new, close, and switch tab flows with independent WebView state and native WebView cleanup.
Keyboard and Menu Commands
Common browser commands are available from the menu and keyboard, including tab, navigation, reload, and address focus.
History & Bookmarks
History is persisted, searchable, grouped by day, and supports multi-select actions. Bookmarks are persisted, searchable, tagged, filterable, and support multi-select deletion.
Window and Tab Management
Add tab reordering, detached tabs, multi-window tab movement, and per-window active tab state.
Downloads
Track downloads, add a
nimlo://downloads page, persist
metadata, open files, and reveal them in
Finder.
Content Blocking
Explore uBlock Origin-inspired blocking with filter-list support, URL-level hooks, per-site controls, and WebKit cosmetic filtering research.
Private Mode UX
Turn the private-mode foundation into a visible incognito experience with private tab/window flows and clear indicators.
Settings
Add user-facing controls for search, homepage, downloads, theme, private behavior, content blocking, and local data.
