Hi HN, I built Lentando, a privacy first tracker for substance use and habits (nicotine, alcohol, cannabis, or custom). It's an offline first PWA, no account required unless you opt into multi device sync. Released under GPL 3.0.

Under the hood it's about 6K lines of vanilla ES6 with no runtime dependencies. To make long term browser storage practical, it consolidates older events while keeping aggregates stable. Optional sync uses a simple conflict tolerant merge (event timestamps and tombstones) so offline edits across devices don't break. Charts are a small custom canvas renderer (stacked bar charts and heatmaps), and there's time travel debugging plus 100+ Node unit tests.

I'd love feedback from both developers and anyone who tries it, on the architecture, the UX, and what you would improve.

Hi HN, I built Robot Social Net, a social network where humans and AI companions share the same feed and can collaborate in real time(and post memes).

The core idea is: humans stay in control of identity + decisions, while an optional AI companion helps with drafting, research, and conversation. You can join as a human, and you can also “deploy” an agent persona that participates in the feed.

What you can do today:

Browse a collective feed that mixes human posts and agent posts

Create a human account and interact

Create an AI companion account (agent) and have it participate as its own persona

What I’m trying to learn from early users:

Does the human + agent model feel useful or gimmicky in practice?

What level of control/visibility do you expect over what an agent can do?

What would make you trust an agent participating in a public conversation?

Happy to answer questions, and I’d love blunt feedback.

Hi HN,

We have built an AI agent that runs tests for any platform using only natural language and visual recognition.

We’ve been building test automation since 2019, and now we realized that all of the challenges—heavy script writing and maintenance overhead are coming from automation code itself.

So what if E2E testing didn’t require code at all?

Instead of generating or maintaining test code, Aximo:

1. Takes a goal in natural language 2. Observes the UI visually 3. Plans and executes actions 4. Evaluates results via vision 5. Iterates until success or failure

It doesn’t rely on DOM selectors or frameworks and observes the interface visually and decides what to do next — similar to how a human tester interacts with software.

With coding agents, software development has become much faster, and we need to test our application more quickly.

We’re curious what this community thinks.

Throughout my career, I tried many tools to query PostgreSQL, and in the end, concluded that for what I do, the simplest is almost always the best: raw SQL queries.

Until now, I typed the results manually and relied on tests to catch problems. While this is OK in e.g., GoLang, it is quite annoying in TypeScript. First, because of the more powerful type system (it's easier to guess that updated_at is a date than it is to guess whether it's nullable or not), second, because of idiosyncrasies (INT4s are deserialised as JS numbers, but INT8s are deserialised as strings).

So I wrote pg-typesafe, with the goal of it being the less burdensome: you call queries exactly the same way as you would call node-pg, and they are fully typed.

It's very new, but I'm already using it in a large-ish project, where it found several bugs and footguns, and also allowed me to remove many manual type definitions.
