Ask HN: What are you working on? (March 2025)
You can choose from common difficult scenarios or create a custom one and get connected with a conversational AI voice agent to practice. Started out with just manager use cases but now testing out sales calls, interviews, pitches, etc.
Mostly built on Replit (would recommend - is amazing & keeps getting better) and relying on a mix of ElevenLabs / OpenAI / Anthropic for the voice & LLM tech.
I’m sure many of you were asked to engage with some product announcement, hiring post, or whatever on LinkedIn. With SocialWeaver, we remove all friction from that process by letting employees like, share, and comment directly within Slack and Teams. On top of the core use case, marketing teams also get analytics, employee leaderboards, content scheduling, etc.

Only public on iOS store for now, due to Google requires larger # of testers to authenticate the app.
This app idea came from my last Japan trip. I had a hard time finding good local restaurants (not tourist traps). So I decided to build this app with Japanese-oriented lists, due to lists' lacked of maps, etc. The app actually helped me discover some great spots, since it lists places all over Japan. Please give it a try and let me know if you have any feature requests or ideas.
After using tools like Sentry on apps serving millions of users, I always felt I was missing a cheap and dead simple approach to following what happened in my apps and apis, and basically became my first customer for all of my side projects and even got some friends using it for their SaaS and apps.
HN is probably not the target audience for this, but I've become really obsessed about solving my own problem of building apps, but struggling to market them. There are very few places online that welcome you to post links, enable you to post a link quickly, and drive targeted traffic at reasonable cost.
So I'm trying to bootstrap a new ad network on Link In Bio platforms that offers this trifecta (welcoming, quick, cost effective).
Motivation for the project:
> This project was born out of the need for a lightweight analytics tool to track internal services on a resource-constrained VPS. Most SaaS analytics products either lack the scalability or exceed their free tier limits when tracking millions of events per month. Minimalytics addresses this gap by offering a minimalist, high-performance solution for resource-constrained environments.
I recently did a Show HN which you can find on my profile.
For whoever aware of recent `tj-actions/changed-files` security incident, I built a mutable-reference scanner that performs a deep scan across branches to identify all third-party GitHub actions used in organization Git projects. The output report can be exported to CSV or JSON (default).
Using mutable references (version tags, main/master/dev etc.) is a security vulnerability that can result in supply-chain attacks.
Project link:
Recon Wave basically finds and scans all their services - DNS, IPs, Apps, Ports - and notify customers when it breaks some policy (aka. "no ports than 443 should be open") or when some service is straight vulnerable.
I'm former security engineer and I hated all that "critical reports" that reported missing CSP header.
We're now playing with an idea to build LLM pentesting agent that could run agains the whole infra of our customers.
What we build is primarily focused on companies that have at least hybrid stack - some on prem, some in cloud. If you completely behind load balancer and have strict change management, we can't bring you any value.
In ideal world, we wouldn't have any business. But oh boy... Companies host wild stuff.
Every single conversation I had with clients ended up with us showing some of their infra and the response was "wow, we didn't know this is ours".
Said every security company ever. :)
