Sandbox Browser
Chromium browser with proxy chaining & sandbox controls
What it does
Sandbox Browser is an open-source wrapper around Chromium that adds a full privacy and network control layer on top of the browser. It brings together an embedded SOCKS5 proxy, Windows AppContainer sandboxing, Psiphon auto-launch and proxy chaining, a VPN-style toolbar toggle, split tunneling, DNS-over-HTTPS, custom HTML/CSS parsers, and TLS fingerprint randomization — all working as one controlled browsing environment for developers, security researchers, and privacy-focused users.

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
