01/04Render room
Each page loads in a sealed room. Nothing else gets in.
VAJRA renders every page in its own process. Ad auctions and tracking scripts are not part of the rendering path.
What it doesDraws each page in a separate, locked-down process.
Without itTrackers load beside the page and build a profile of you.
02/04Tab isolation
Each tab has its own space. Tabs cannot see each other.
Every tab gets its own process list, network and message channels. One tab cannot read or watch another.
What it doesRuns each tab in unprivileged Linux namespaces.
Without itOne compromised site could read data from your other tabs.
03/04System calls
Tabs make only approved requests. Everything else is blocked.
Before a tab can talk to the operating system, seccomp-BPF checks the request. Anything not on the allowed list is stopped.
What it doesAllows reading, writing and memory use. Blocks mounting drives, tracing and starting programs.
Without itA hacked tab could start programs or watch other apps.
04/04Memory
Closing a tab erases its memory. Nothing is left to recover.
When a tab closes, its heap pointers, keys and cache registers are overwritten with zeros in under 0.08 ms.
What it doesOverwrites the tab’s memory and deleted history so neither can be recovered.
Without itPasswords and session keys can stay in RAM for forensic tools to find.
VAJRA is a private web browser for Linux. It seals every tab, checks every system call and erases a tab’s memory the moment you close it.

The Briefing
The frontier of sovereign intelligence, explained.
What if you could peer inside the kernel memory of an autonomous web agent? You would find no tracked profiling tokens, just sealed user namespaces and zero-telemetry address maps.
Autonomous engines execute multi-step plans. Here is how zero-telemetry sandboxing prevents agent collusion and privacy leakage.
A look back at the architecture that replaced billion-dollar JavaScript ad auctions with bare-metal C++ deterministic rendering pipelines.
NEXAUR's vision for local GPU-accelerated Vulkan neural shaders, complete digital independence and zero reliance on external clouds.
The zero-fill algorithm that synchronously purges volatile address registers the exact millisecond a tab or session is destroyed.

FAQ
Questions about VAJRA
What is VAJRA Browser?
VAJRA is a fast, private web browser for Linux, built in India by NEXAUR Technologies Private Limited. It is built on an updated Chromium base, with its own VAJRA engine coming soon, and adds per-tab kernel sandboxing, built-in ad and tracker blocking, on-device AI and zero telemetry.
Is VAJRA free, and which systems does it run on?
VAJRA is free to download. It runs on Linux (Debian, Ubuntu and compatible distributions, as a .deb package) and on Android (from Google Play, plus a beta .apk).
Does VAJRA collect telemetry or track me?
No. VAJRA sends zero telemetry. Trackers and cross-site cookies are blocked at the network level, and session data is zero-filled from memory the moment a tab closes.
How does VAJRA block ads and trackers?
The VAJRA Shield ad blocker removes ads, pop-ups and video ads before they load, and the Tracker Blocker stops trackers and cross-site cookies. Pages open faster and use less data and battery.
How does the Security Enclave keep my tabs safe?
Every tab runs in its own unprivileged sandbox with strict seccomp-BPF system-call filtering and isolated PID, NET and IPC namespaces. If a page is attacked, the exploit stays inside that one tab.
Can I use AI in VAJRA without sending data to the cloud?
Yes. The Vulkan Neural Copilot runs quantized Whisper and LLaMA models on your own GPU, and the On-device Scam Guard checks links locally. No prompt tokens are sent to the cloud.
What is the Cryptographic Memory Shredder?
When a tab closes, heap pointers, decryption keys and cache registers are zero-filled in under 0.08 ms. This blocks cold-boot forensics, and deleted history is overwritten so it cannot be recovered.
Who makes VAJRA Browser?
VAJRA is engineered by NEXAUR Technologies Private Limited (CIN: U63111MR2026PTC473561), an Indian deep-tech company.
Is VAJRA a good Chrome alternative for Linux?
VAJRA is a Chrome alternative built for Linux. In NEXAUR's own test it started 3.4x faster than legacy Chrome. It sends zero telemetry and includes an ad blocker, a tracker blocker and per-tab sandboxing without extensions.
How do I install VAJRA on Ubuntu, Debian or Fedora?
On Debian or Ubuntu, download the .deb package and run: sudo apt install ./vajra-4.0.deb. On Android, install VAJRA from Google Play, or download the beta .apk from this page.
Is VAJRA based on Chromium?
VAJRA is built on an updated Chromium base, with its own privacy, sandboxing and on-device AI layers on top. NEXAUR is also building its own VAJRA engine, which will arrive in a later update.
Is VAJRA available on Google Play?
Yes. The stable VAJRA Browser for Android is on Google Play (package com.nexaur.zenith_browser). A beta .apk is also available on this page for people who prefer a direct download.
Does VAJRA work on Windows or macOS?
VAJRA currently runs on Linux and Android. Windows and macOS builds are coming soon.
Does VAJRA protect against browser fingerprinting?
Yes. The Fingerprint Shield randomizes details that websites use to recognize your device, such as canvas, fonts and screen data, so trackers cannot build a profile of you.
Does VAJRA use HTTPS and encrypted DNS?
Yes. VAJRA upgrades connections to HTTPS and encrypts DNS lookups, so your internet provider cannot easily see which websites you visit.
How is VAJRA different from Brave or Firefox?
With default settings, VAJRA sends no telemetry, blocks ads and trackers by default, writes no browsing data to disk, runs every tab in its own kernel sandbox and zero-fills a tab's memory when it closes. The comparison table on this page shows how Chrome, Firefox and Brave differ, based on default settings and public vendor documentation.
