Show HN: I made a Chrome Extension to stop mindless browsing / avoid tab clutter Hey HN, I've created on a Chrome Extension called Lucid to help me maintain my focus while browsing. It has been working great for me, so I wanted to share it here. Whenever I start browsing with a certain intention, I always find myself get off track, doing some other thing, forgetting about my intention. This also leads to like 20+ cluttered tabs, not knowing what to keep or close. So I built Lucid. Simply stating my intention (1) creates a floating reminder that follows me everywhere, and (2) creates a tab group off of the intention so the tabs will be organized automatically. You can add multiple intentions as well. I hope this helps, and I would love to hear your feedback! CB https://bit.ly/4jxm3uj April 1, 2025 at 12:09AM

Show HN: I built an open-source NotebookLM alternative using Morphik https://bit.ly/3FYyYGQ

Show HN: I built an open-source NotebookLM alternative using Morphik I really like using NoteBook LM, especially when I have a bunch of research papers I'm trying to extract insights from. For example, if I'm implementing a new feature (like re-ranking) into Morphik, I like to create a notebook with some papers about it, and then compare those models with each other on different benchmarks. I thought it would be cool to create a free, completely open-source version of it, so that I could use some private docs (like my journal!) and see if a NoteBook LM like system can help with that. I've found it to be insanely helpful, so I added a version of it onto the Morphik UI Component! I'd love to hear the HN community's thoughts and feature requests! https://bit.ly/3DX90mE March 31, 2025 at 02:01AM

Show HN: Cloud-Ready Postgres MCP Server https://bit.ly/3RpxI1V

Show HN: Cloud-Ready Postgres MCP Server Hey HN, I built pg-mcp, a Model Context Protocol (MCP) server for PostgreSQL that provides structured schema inspection and query execution for LLMs and agents. It's multi-tenant and runs over HTTP/SSE (not stdio) Features - Supports multiple database connections from multiple agents - Schema Introspection: Returns table structures, types, indexes and constraints; enriched with descriptions from pg_catalog. (for well documented databases) - Read-Only Queries: Controlled execution of queries via MCP. - EXPLAIN Tool: Helps smart agents optimize queries before execution. - Extension Plugins: YAML-based plugin system for Postgres extensions (supports pgvector and postgis out of the box). - Server Mode: Spin up the container and it's ready to accept connections at http://localhost:8000/sse https://bit.ly/4hYL4xd March 30, 2025 at 04:14AM

Show HN: Create presentations with smart animations using Excalidraw https://bit.ly/43re0dz

Show HN: Create presentations with smart animations using Excalidraw I often create presentations where elements need to move (animate) from one slide to the next. This is great for explaining algorithms, workflows, or anything that benefits from dynamic visuals. I used to rely on Figma prototypes with smart animations for this, but I wanted a way to do it in Excalidraw—maybe even more conveniently. So I made an Excalidraw fork which helps you present "frames" and interpolates animations between them. Video demo (detecting cycles in a graph): https://bit.ly/42bK2rR...

Show HN Pianoboi – displays sheet music as you play your piano https://bit.ly/4l47kIR

Show HN Pianoboi – displays sheet music as you play your piano I made a software library for displaying piano music 7 years back, and recently ported it to the web (which is now easier than even ever). It displays sheet music as you play, and let's you take snapshots of specific chords, then keeps a running list of chords as keyboard visuals (instead of just displaying sheet music). Just a simple tool for songwriting/ figuring out songs by ear, or just understanding music key theory (which I'm admittedly a still a beginner at). https://bit.ly/42hLPf4 March 28, 2025 at 04:55PM

Show HN: An Almost Free, Open Source TURN Server https://bit.ly/3FK49FU

Show HN: An Almost Free, Open Source TURN Server Hi HN, I have been messing around with WebRTC for a few years now but when it comes to the TURN server I never quite got to my gold standard of free, self-hosted and open source. I decided to give it a go using Oracle Cloud Infrastructure's free tier, meaning that my total spend got down to domain name hosting. I know plenty of people have been burnt by Oracle in the past, but I have had servers running on the free tier for 5 years now without so much as a hiccup. Regardless, the concepts will be the same using any cloud based server. This is the first time I've written up an end-to-end technical how-to like this and the audience I am writing for is really myself - I know just enough about networks and web dev and Linux, etc to get all this running and there are plenty of snippets out there on the web that tell you how to do one thing or another, but nowhere that puts it all together in one place so if I'm explaining what is obvious to you, my apologies - like I say, I'm writing to myself here. I don't know that this even is a Show HN - @dang, if it isn't, please feel free to recategorise/edit the title. @Everybody else, I am happy to answer questions if I can but please bear in mind that I am not claiming to be an expert on any of the tech gathered together to make this work. https://bit.ly/4ck4XO4 March 28, 2025 at 11:46PM

Show HN: Calculating prices in work hours, not dollars https://bit.ly/43LrAc3

Show HN: Calculating prices in work hours, not dollars Ever looked at a price tag and thought, How many hours do I need to work for this? Instead of just seeing numbers, what if you could instantly see the cost in terms of your time? That’s why I built Time for Price — a simple browser extension that converts prices into work hours based on your income. Whether you're shopping online or budgeting, it helps you make decisions with time in mind, not just money. Just enter your hourly wage, and the extension automatically overlays the converted value on any product page. No more impulse buys—just instant, clear insight into what something really costs you. We’re launching soon! Join the waitlist at https://bit.ly/4iD7lSc to get early access. https://bit.ly/4iD7lSc March 27, 2025 at 01:36AM

I’ve been sharing a bunch of free Tailwind CSS components on X, but honestly, they just keep getting buried in the timeline. It’s super frustrating when something you put effort into disappears so quickly. That’s why I decided to put everything on a website. Now you can easily find all the components I’ve shared in one place, and I’ll keep adding any new ones I create. It feels good to have a space where they won’t get lost.

Show HN: I made a fetch client builder to make API calls simpler and safer https://bit.ly/4iI9lZC

Show HN: I made a fetch client builder to make API calls simpler and safer I built this library because I kept rewriting the same fetch wrapper for every project. Each time, I needed the same core features: - Make fetch throw errors to integrate smoothly with libraries like TanStack Query - Add sensible defaults to the Fetch API, like a base URL and authentication headers - Validate responses for type safety when OpenAPI isn’t an option I also wanted the library to feel exactly like using fetch — no new API to learn, and no extra friction for my teammates. While there are other great options out there, I found many were either too rigid or too bulky. Doesn’t it feel wrong to ship a 14kb fetch library to the client? To keep up-fetch small and flexible, I took a simple approach: lightweight defaults, paired with inversion of control, so users can easily override what they need. The result? up-fetch weighs just 1.6kb gzipped, with built-in validation (powered by Standard Schema), configurable options, retries, timeouts, streaming & progress tracking, lifecycle hooks, and more. Check it out if you’ve got a minute — I’d love to gather some feedback! https://bit.ly/4iGGtRd March 26, 2025 at 01:11PM

Show HN: A website for sharing the "Good, Bad, and Why"s of urban spaces Hello HN! We're a small team in Kyoto building a website called dédédé ( https://bit.ly/4jof9rd ) that invites people to share the various positives, negatives, oddities, etc. they find in urban spaces. The project grew out of an earlier effort where we'd built an app that assisted participatory urbanism workshops run by local nonprofits. With the new platform, we're trying to build something similar but more casual and hopefully with broader appeal, that'll be fun to use even outside of formal workshop situations. We'd love to hear your thoughts! https://bit.ly/4jof9rd March 24, 2025 at 10:48PM
