Show HN: Local Privacy Firewall-blocks PII and secrets before ChatGPT sees them https://ift.tt/mA8g54N

Show HN: Local Privacy Firewall-blocks PII and secrets before ChatGPT sees them OP here. I built this because I recently caught myself almost pasting a block of logs containing AWS keys into Claude. The Problem: I need the reasoning capabilities of cloud models (GPT/Claude/Gemini), but I can't trust myself not to accidentally leak PII or secrets. The Solution: A Chrome extension that acts as a local middleware. It intercepts the prompt and runs a local BERT model (via a Python FastAPI backend) to scrub names, emails, and keys before the request leaves the browser. A few notes up front (to set expectations clearly): Everything runs 100% locally. Regex detection happens in the extension itself. Advanced detection (NER) uses a small transformer model running on localhost via FastAPI. No data is ever sent to a server. You can verify this in the code + DevTools network panel. This is an early prototype. There will be rough edges. I’m looking for feedback on UX, detection quality, and whether the local-agent approach makes sense. Tech Stack: Manifest V3 Chrome Extension Python FastAPI (Localhost) HuggingFace dslim/bert-base-NER Roadmap / Request for Feedback: Right now, the Python backend adds some friction. I received feedback on Reddit yesterday suggesting I port the inference to transformer.js to run entirely in-browser via WASM. I decided to ship v1 with the Python backend for stability, but I'm actively looking into the ONNX/WASM route for v2 to remove the local server dependency. If anyone has experience running NER models via transformer.js in a Service Worker, I’d love to hear about the performance vs native Python. Repo is MIT licensed. Very open to ideas suggestions or alternative approaches. https://ift.tt/Sd2Ahtb December 9, 2025 at 01:10PM

Show HN: I made a fighting game where Elon and Zuck can settle it Browser-based fighting game where you can play as Elon, Zuck, Jensen, Sam, or Sundar. Built it over a couple weekends using Claude Code and Cursor, deployed on Vercel. https://ift.tt/t1LDHW6 December 10, 2025 at 08:55AM

Show HN: The Box – Run multiple Claude CLI agents in parallel in the cloud https://ift.tt/SC1tcJi

Show HN: The Box – Run multiple Claude CLI agents in parallel in the cloud Hey HN, I'm a solo developer and kept running into the same problem: I'd want Claude CLI to work on multiple tasks at once, but locally I could only run one instance at a time. So I built The Box. It lets you spin up isolated sandbox environments in the cloud and run Claude CLI agents in parallel. You write the prompt, pick a GitHub repo, and it handles the rest – creates a branch, does the work, and opens a PR. The core workflow: - Connect your GitHub repos - Create tasks with prompts - Claude CLI runs in isolated sandboxes - Get notified when done (browser push or Telegram) - Review and merge PRs Tech stack: Go (Fiber) for backend services, Next.js for frontend, PostgreSQL, Redis for signaling, RabbitMQ for task queue. Workers run Claude CLI in Docker containers. Currently free to use (with limits) while I finish payment integration. Would love feedback from anyone who's tried to scale their AI coding workflow. https://the-box.dev https://the-box.dev December 10, 2025 at 03:53AM

Show HN: DskDitto DskDitto is a small CLI utility that rapidly scans your disk for duplicates wasting disk space. It’s written in Golang and provides a sleek TUI to interactively manage file dups. It’s very fast and capable but the project is still somewhat in its infancy. If any one wishes to become a contributor please reach out. Feedback welcome. Thanks :-) https://ift.tt/OqQrakH December 10, 2025 at 02:35AM
