Show HN: I built a dashboard to compare mortgage rates across 120 credit unions
When I bought my home, the big bank I'd been using for years quoted me 7% APR. A local credit union was offering 5.5% for the exact same mortgage.
I was surprised until I learned that mortgages are basically standardized products – the government buys almost all of them (see Bits About Money: https://www.bitsaboutmoney.com/archive/mortgages-are-a-manuf...). So what's the price difference paying for? A recent Bloomberg Odd Lots episode makes the case that it's largely advertising and marketing (https://www.bloomberg.com/news/audio/2025-11-28/odd-lots-thi...). Credit unions are non-profits without big marketing budgets, so they can pass those savings on, but a lot of people don't know about them.
I built this dashboard to make it easier to shop around. I pull public rates from 120+ credit union websites and compares against the weekly FRED national benchmark.
Features:
- Filter by loan type (30Y/15Y/etc.), eligibility (the hardest part tbh), and rate type - Payment calculator with refi mode (CUs can be a bit slower than big lenders, but that makes them great for refi) - Links to each CU's rates page and eligibility requirements - Toggle to show/hide statistical outliers
At the time of writing, the average CU rate is 5.91% vs. 6.23% national average. about $37k difference in total interest on a $500k loan. I actually used seaborn to visualize the rate spread against the four big banks: https://www.reddit.com/r/dataisbeautiful/comments/1pcj9t7/oc...
Stack: Python for the data/backend, Svelte/SvelteKit for the frontend. No signup, no ads, no referral fees.
Happy to answer questions about the methodology or add CUs people suggest.
Show HN: Fresh – A new terminal editor built in Rust
I built Fresh to challenge the status quo that terminal editing must require a steep learning curve or endless configuration. My goal was to create a fast, resource-efficient TUI editor with the usability and features of a modern GUI editor (like a command palette, mouse support, and LSP integration).
Core Philosophy:
- Ease-of-Use: Fundamentally non-modal. Prioritizes standard keybindings and a minimal learning curve.
- Efficiency: Uses a lazy-loading piece tree to avoid loading huge files into RAM - reads only what's needed for user interactions. Coded in Rust.
- Extensibility: Uses TypeScript (via Deno) for plugins, making it accessible to a large developer base.
The Performance Challenge:
I focused on resource consumption and speed with large file support as a core feature. I did a quick benchmark loading a 2GB log file with ANSI color codes. Here is the comparison against other popular editors:
- Fresh: Load Time: *~600ms* | Memory: *~36 MB*
- Neovim: Load Time: ~6.5 seconds | Memory: ~2 GB
- Emacs: Load Time: ~10 seconds | Memory: ~2 GB
- VS Code: Load Time: ~20 seconds | Memory: OOM Killed (~4.3 GB available)
(Only Fresh rendered the ansi colors.)Development process:
I embraced Claude Code and made an effort to get good mileage out of it. I gave it strong specific directions, especially in architecture / code structure / UX-sensitive areas. It required constant supervision and re-alignment, especially in the performance critical areas. Added very extensive tests (compared to my normal standards) to keep it aligned as the code grows. Especially, focused on end-to-end testing where I could easily enforce a specific behavior or user flow.
Fresh is an open-source project (GPL-2) seeking early adopters. You're welcome to send feedback, feature requests, and bug reports.

Show HN: A Minimal Monthly Task Planner (printable, offline, no signup)
Hi HN,
I built a tiny tool because I couldn’t find a clean, distraction-free monthly planner that:
1. shows a clean monthly task view 2. doesn’t require an account 3. doesn’t sync or store anything online 4. works offline 5. is printable 6. and keeps a minimal, distraction-free aesthetic
So I made https://printcalendar.top/ — a minimal monthly task planner.
It’s intentionally simple. No logins, no integrations, no dashboards. Just a small tool for people who want structure without clutter.
Show HN: I Built an UI Library that lets you create beautiful UIs in Minutes
Hello Everyone,
My name is Karan, and I'm a Frontend Developer, but I feel like I'm more of a Design Engineer because of my love for creating UIs
When I started my development journey, I fell for frontend development and stuck with it ever since
But I noticed that many of my friends hated writing CSS because creating UIs is a very tedious and time-consuming process, and you have to be pixel-perfect
But at the same time, they also wanted their project to look premium with beautiful animations and a world-class user experience
That's when I thought
"What if anyone could integrate beautiful animated components into their website regardless of their CSS skills?"
And after six months of pain and restless nights, I finally built ogBlocks to solve this problem.
It is an Animated UI Library for React that contains all the cool animations that will make it look premium and production-grade
ogBlocks has navbars, modals, buttons, feature sections, text animations, carousels, and much more.
I hope you'll love it
Best Karan

Show HN: Microlandia, a brutally honest city builder
It all started as an experiment to see if I could build a game making heavy use of Deno and its SQLite driver. After sharing an early build in the „What are you working on?“ thread here, I got the encouragement I needed to polish it and make a version 1.0 for Steam.
So here it is, Microlandia, a SimCity Classic-inspired game with parameters from real-life datasets, statistics and research. It also introduces aspects that are conveniently hidden in other games (like homelessness), and my plan is to continue updating, expanding and perfecting the models for an indefinite amount of time.

Show HN: RAG in 3 Lines of Python
Got tired of wiring up vector stores, embedding models, and chunking logic every time I needed RAG. So I built piragi.
from piragi import Ragi
kb = Ragi(\["./docs", "./code/\*\*/\*.py", "https://api.example.com/docs"\])
answer = kb.ask("How do I deploy this?")
That's the entire setup. No API keys required - runs on Ollama + sentence-transformers locally.What it does:
- All formats - PDF, Word, Excel, Markdown, code, URLs, images, audio
- Auto-updates - watches sources, refreshes in background, zero query latency
- Citations - every answer includes sources
- Advanced retrieval - HyDE, hybrid search (BM25 + vector), cross-encoder reranking
- Smart chunking - semantic, contextual, hierarchical strategies
- OpenAI compatible - swap in GPT/Claude whenever you want
Quick examples: # Filter by metadata
answer = kb.filter(file_type="pdf").ask("What's in the contracts?")
#Enable advanced retrieval
kb = Ragi("./docs", config={
"retrieval": {
"use_hyde": True,
"use_hybrid_search": True,
"use_cross_encoder": True
}
})
# Use OpenAI instead
kb = Ragi("./docs", config={"llm": {"model": "gpt-4o-mini", "api_key": "sk-..."}})
Install: pip install piragi
PyPI: https://pypi.org/project/piragi/
Would love feedback. What's missing? What would make this actually useful for your projects?

Show HN: CSVtoAny, CSV Local File Converter
About two weeks ago I built a small text-comparison tool as a simple front-end project. Recently I ran into another annoyance: converting CSV/Excel/JSON with tools that upload files to servers, feel slow, or impose limits. Since I prefer privacy-first tools, I built this one as well.
100% local: All parsing and conversion run in Web Workers. No uploads.
Format support: CSV ↔ Excel (.xlsx), JSON, SQL, XML, Markdown.
Smart column restoration: Fixes copied tables that collapse into a single column (enable under “More Options”).
No size limits: Only limited by your RAM.
My goal is to grow this into a small, one-stop CSV/format toolbox. It just launched, so there may be rough edges — feedback is welcome.
Tech
Next.js, Tailwind, SheetJS, Web Workers, i18next.
Looking for feedback
Try it with your odd CSVs: unusual delimiters, quoted newlines, mixed encodings, huge files, broken pasted tables. Also curious whether the column-restoration feature feels intuitive.
Thanks for checking it out!

Feedback I’m looking for:
which regions matter most,
which geo-specific behaviors you need to validate,
local vs cloud mode preference.
Happy to answer technical questions.
Show HN: I made a simple, 100% free marketplace to buy or sell micro-startups
I build a lot of small products myself and I realized how many indie founders want an exit that doesn’t involve platforms charging large commissions or requiring big revenue numbers. Sometimes a project makes $50/month, sometimes $500, sometimes $0 but has a great codebase, and that’s enough value for someone else.
So I built buy-startups.com, a very simple, privacy-friendly marketplace for buying and selling small online startups.
It’s not fancy. There’s no commission, no listing fee, no hidden funnel. Just a straightforward way for indie devs and bootstrappers to list a project and connect with someone who wants to pick it up.
