hackertab.dev
A Chrome 🌐 & Firefox 🦊 extension to discover the latest developer news and tools in one tab!
Project mention: Show HN: OpenFeed – private dev news in your new tab, with LinkedIn and X feeds | news.ycombinator.com | 2026-05-26Fork of Hackertab (https://github.com/medyo/hackertab.dev). All sources fetch directly in your browser - nothing goes through a server.
LinkedIn and X work via your existing session cookies. Onboarding runs Claude (your claude.ai session) in the background to infer your stack from your LinkedIn profile. No credentials stored, no data leaves your machine.
LinkedIn, X, and Claude.ai technically restrict this kind of access — though it's your own data, in your own browser. Use at your own discretion.
