Show HN: Securing GrokBot

A friend at another tech startup was telling me how they started using Grok Bot and loved it. Surprise surprise they also got pretty worried about what it's doing and the visibility they had. Digging under the hood, hey there's a Linux VM and a Chrome browser. This is really cool because it essentially defines an environment that is really similar to a typical workstation. After some playing around I got the LimaCharlie EDR installed, the Chrome LC EDR installed and the email provider connected

Show HN: Radio Dystopia

I love the dry techno sound of Commodore 64 SID tunes for deep work, but realized I like them even better with a custom effects/mastering chain, and there was no existing online place to get that. And given the times, I also added dystopian ads and DJ banter from planet Zomrog to set the right vibe. So basically a 24/7 wordless web radio station that plays very obscure techno and is also a kind of long-form radio play

Show HN: Revline – An open-source AI-native video editor

Hi HN, I'm Zura, and I'm building Revline, a fully agentic video editor. Revline can take your rough draft of a short or long video, watch it, understand the content, and make edits like a real editor would. It's been super useful for me (not biased, obviously). I want to post more content, but my output has never matched how frequently I want to post. Editing takes too much time, and every video I don't finish is waste of time(and money). The problem I've had (and still have) with current &quot

Show HN: Typos – Render Typst Documents to Thermal Printers (Go and ESC/POS)

I built typos because handling CJK fonts (Korean in my case) natively on thermal printers using standard ESC/POS code pages was pretty terrible. Instead of messing with internal fonts, I've decided to write a simple script that can do Typst -> Image -> Print. It features CLI, an optional REST server with async job queue and with template support. The core Go CLI and printer logic are 100% hand-written. I experimented with AI tools via Opencode to write the REST API once the core logic was

Ask HN: Are you building an AI company brain?

Hey guys, the CTO requested me to start working towards building a "AI company brain", some sort of entity that keeps the context of what's going on in the company so different roles can use AI agents/interfaces in order to do things like: - draft emails or presentations. - prepare meetings and provide the current context to the employees. - update clients information after meeting based on transcripts or employee notes. - query different sources in order to gather how our system is wo

Show HN: Penthera, offline pentest security scanner (open-source, rule-based)

local non-AI security for your app/site! For years I had a long .txt file with hundreds of manual security checks I ran before pushing a (client) app/site to live; I am really a rookie compared to the real cyber experts, but just covering the basics has saved us many times from malicious attacks on our infrastructure. With the sprawl of AI generated vibecoded apps (I love it, i think creating should be accessible, but so should be cyber safety) and AI coding tools, our code goes to LLM providers
