GeoSpoof – your VPN hides your IP, but the browser leaks your location
Hello HN, I started building GeoSpoof after I noticed my IP says one country, but the browser still hands sites my real location. Websites were flagging me because of this discrepancy. I searched for a good geolocation spoofer, only to go down a rabbit hole that there are dozens of signals that your browser emits and no tool could cover them all on every platform. GeoSpoof overrides every location-related API to present one consistent signal for location. You can search a city, enter coordinates, or hit "Sync with VPN" to auto-detect your exit region and match it, which re-syncs when you…
In plain words
GeoSpoof is a browser tool that masks geolocation data to prevent websites from detecting mismatches between a user's VPN IP address and actual location. It overrides multiple location-related browser APIs—including Geolocation, Date, and Worker functions—to present a consistent signal across all platforms. Users can manually select a location by city or coordinates, or sync automatically with their VPN provider's exit region. The tool is designed for people using VPNs who encounter website blocks or flags due to location discrepancies.

In the maker’s words, at launch
Hello HN, I started building GeoSpoof after I noticed my IP says one country, but the browser still hands sites my real location. Websites were flagging me because of this discrepancy. I searched for a good geolocation spoofer, only to go down a rabbit hole that there are dozens of signals that your browser emits and no tool could cover them all on every platform. GeoSpoof overrides every location-related API to present one consistent signal for location. You can search a city, enter coordinates, or hit "Sync with VPN" to auto-detect your exit region and match it, which re-syncs when you switch servers. The overrides are disguised (Function.prototype.toString returns [native code], iframes patched on insert) so they survive the common fingerprinting checks. Some examples of APIs covered: - Geolocation - Date - Temporal - EXSLT - Worker & Shared Worker (blob / data / URL scripts) - WebRTC - Deep engine-level spoofing on Chromium browsers with the CDP debugging api (opt-in) It's cross-browser (Firefox, Chrome/Brave/Edge, Safari), available on mobile platforms as well (Android Firefox, iOS Safari), MIT licensed, with no backend or telemetry.

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…
