Attention
Workspaces, per-project tabs, and custom home shortcuts that match how you actually work — not one endless pile of tabs.
v0.1.81 · Signed & notarized · Auto-updates
The browser that remembers your projects — without trading your attention for ads.
Lumpini is the calm, privacy-first browser for macOS. Workspaces, encrypted passwords, blocking rules, and history live on your machine — not in someone else’s cloud. No account. No feed. No noise.
Product pillars
Built for attention, trust, and focus
Named for Lumpini Park in Bangkok — a place to breathe and reset in the middle of a busy city. The browser should feel like calm infrastructure in a noisy digital world.
Trust
Transparent privacy controls, certificate warnings you can read, measurable blocking, and an encrypted vault you own — no vague “AI protection.”
Privacy
Ad & tracker blocking, DNS-over-HTTPS, fingerprint protection, and local download scanning — all visible, all on your device.
Performance
A lightweight Rust + Tauri shell over native WebKit — respect for battery and RAM, with a watchdog that keeps the interface responsive.

Built-in
Best-in-class where it matters — none of the noise
No crypto widgets, engagement sidebars, or feeds built to keep you scrolling. Every default is disclosed and editable. Everything below ships today.
Workspaces
Switch between projects with persistent tabs per workspace — stored locally in SQLite on your disk, restored exactly as you left them.
Encrypted Vault
AES-256-GCM credentials with Argon2 key derivation, login autofill (even on tricky single-page apps), search & sort, and a master password that never leaves your machine.
Passkeys
WebAuthn support is built in and handled honestly today. The macOS Touch ID passkey sheet requires Apple’s browser entitlement, which is in Apple’s review process — it lights up the moment Apple approves.
Privacy & Protection
Ad and tracker blocking with native WebKit content rules, optional fingerprint protection, malware & phishing blocklists, per-site controls, and a blocked-request log.
DNS-over-HTTPS
Encrypt your DNS lookups so your network can’t see or tamper with the sites you visit — one toggle, no system-wide changes.
Readable security warnings
Clear certificate-error and “not secure” bars with a deliberate proceed-anyway flow, plus local ClamAV download scanning when enabled.
Download manager
Progress bar with cancel, one-click Open and Reveal in Finder, and a private fallback folder that works without granting system file access.
Default browser, done right
Set Lumpini as your macOS default — it opens links from other apps and local .html files, cold-start included.
Signed, notarized, auto-updating
Developer ID–signed and Apple-notarized builds with cryptographically signed in-app updates — you always know what you’re running.
Calm interface
Fourteen built-in themes, auto-hide toolbar, Dock-style tab magnification, and resizable tab bars on top, bottom, left, or right.
18 languages, including RTL
The full interface — menus, settings, even internal pages — is localized in 18 languages with right-to-left support.
Tools without extensions
Bookmarks, history, home shortcuts, network tools, view source, and print to PDF or PNG — fewer extensions, less attack surface.

Where Lumpini leads — and where it’s honest
