Show HN: Creating PDF documents with rotativa.io templates

Hacker News - Tue, 02/10/2026 - 6:50am

Rotativa.io’s template editor makes it easy to create, manage, and preview PDF templates using the powerful Liquid templating language. The Rotativa.io API will then serve your dynamic PDF documents, you’ll just need to send your data as a JSON document. In this guide, we’ll walk you through everything you need to know to get started.

Show HN: ZeroSum – I built a zero-based budgeting app

Hacker News - Tue, 02/10/2026 - 6:47am

Hey HN, been working on this for a while and finally put it out there.

I've used YNAB for a few years for zero-based budgeting. It works, but I never once used the automatic bank import — I just manually enter everything. Paying $109/yr (plus tax) for that felt like a lot. Their pricing went up over the years too and there's only one plan, so you're paying for auto-import whether you want it or not.

So I built ZeroSum (zerosum.so). The idea is simple — if you don't need bank sync, you shouldn't pay for it.

Basic plan is $50/yr, Pro with automatic bank sync is $70/yr. Both still cheaper than YNAB.

Tech-wise it's a React frontend (Vite + Tanstack Router + Tanstack Query) with a Node backend (Hono + tRPC) hosted on Cloudflare Pages (Client) and Render (API + DB). Fully responsive, works well on mobile.

I built a YNAB import wizard so people can migrate their existing budgets and accounts without having to start over.

Things I think turned out well: the reporting and analytics are a lot more useful than what I had in YNAB, the UI feels more modern, and the whole thing just feels snappier to me. Again, biased.

Being honest about what's not ready yet — the Pro plan with bank sync isn't active. We're waiting on Plaid to approve our access. And a native mobile app is something I want to do but no date on that.

Would love feedback from anyone who does zero-based budgeting or has opinions on the UX. Happy to talk about the technical side too if anyone's curious.

Show HN: Kybera – Agentic Smart Wallet with AI Osint and Reputation Tracking

Hacker News - Tue, 02/10/2026 - 6:46am

AI and robotics are compressing traditional employment faster than new industries can absorb the displaced workforce. As that accelerates, more people will turn to speculative markets - not out of greed, but necessity. DeFi is the most accessible speculative market in the world: no broker, no accredited investor check, no KYC gatekeeping. But it's also the most hostile environment for newcomers - scam tokens, rug pulls, fragmented tooling across chains. I built Kybera to lower that barrier. It's a fully client-side, no-backend crypto wallet supporting 8 chains (Ethereum, Base, Solana, and more) with built-in swaps via Jupiter and KyberSwap, cross-chain bridging, and an AI-powered research agent. Paste a contract address and it runs automated OSINT - developer identity verification across ENS, X, Farcaster, and GitHub, holder concentration analysis, liquidity depth - and produces a structured risk rating (SAFE / POTENTIAL / HIGH RISK / AVOID).

The AI isn't just a research layer - it can control the wallet directly. Create wallets, switch networks, check balances, get swap quotes, and execute trades, all through natural language. High-risk actions like transfers and deletions require explicit user confirmation before executing. The goal is that someone who's never used a DEX can go from research to informed trade without needing to understand the underlying mechanics.

Two things on the roadmap I think matter most:

1) Fiat on/off-ramping. The biggest barrier for someone entering DeFi for the first time isn't understanding swaps - it's getting money into a wallet at all. And equally important, getting it back out. If this is going to serve people who aren't already crypto-native, the full journey from bank account to speculative position and back needs to be seamless.

2) Historical developer reputation. Right now the AI analyses a token at a point in time. I want to build a system that looks backwards - indexing past launches, tracking which developers shipped legitimate projects versus rugs, and building high-fidelity reputation profiles over time. When a new token launches, you'd immediately know whether the developer behind it has a track record worth trusting. Essentially a credit score for on-chain builders.

Everything runs in the browser. No accounts, no telemetry, no backend. Keys are AES-256 encrypted, decrypted on-demand, and wiped from memory after use. MIT licensed: https://github.com/Xipzer/Kybera_App

I'd really appreciate any feedback, especially on the developer reputation model - how to make it robust against Sybil attacks and identity fragmentation across chains.

Show HN: I built a portfolio builder for mobile developers

Hacker News - Tue, 02/10/2026 - 6:45am

I’m a mobile developer, and I often ran into the same problem: every time I wanted to showcase my apps, I had to manually collect screenshots, icons, descriptions, and links, or build a small website just to present them.

It felt like too much work for something that should be simple.

So I built Mobile Page. It generates a clean, shareable portfolio for your mobile apps in minutes. You can paste an App Store link or search for your app directly, and the page is created automatically with screenshots, icons, and descriptions.

The goal is to make it easier for mobile developers to present their work, whether for clients, recruiters, or just sharing projects online.

I’d really appreciate any feedback, ideas, or criticism. I’m especially interested in hearing what features would make something like this genuinely useful for you.

Show HN: Snapfridge–vision-based grocery assistant built with Lovable and Gemini

Hacker News - Tue, 02/10/2026 - 6:39am

Hi HN, I noticed that me and my wife were spending time every week to plan meals and prepare the shopping list. I thought this could be a great application for an AI agent.

I realized there was a cold start problem so I added a functionality to start from a fridge photo.

You can try the app without registering, but the agent can keep track of preferences of the user of registered.

I built this MVP using Lovable. As a dev, I wanted to see how far I could push "AI-assisted development" for a full-stack PWA. It allowed me to skip the boilerplate and focus entirely on the prompt-engineering for the Gemini vision logic and the Supabase integration. I was skeptical about "generated code," but the speed at which I could iterate on the UI while maintaining a clean React/Supabase architecture was a game-changer for this specific project.

Ask HN: What do you want people to build?

Hacker News - Tue, 02/10/2026 - 6:39am

We do "what are you building?" threads all the time. I want to hear the other side. What's a tool, product, or service you'd actually use that nobody seems to be making? Could be a better version of something that exists, or something totally new.

Show HN: Run AWS CDK apps locally - speeding up agentic coding

Hacker News - Tue, 02/10/2026 - 6:39am

Rum AWS CDK apps locally as you develop allowing your coding agents to test as they build.
