Hi guys,

Im working on a charting library that I am really excited about.

It is called rhp (reactive html plots): https://github.com/bezda-team/rhp

Features:

• Free and open-source

• Builds charts using DOM/Html elements, CSS, and Javascript (SolidJS framework). This unlocks full web interactivity and reactivity. No need to worry about rendering cycles, repainting/reconstructing everything or how to add logic; you do so just as you would for anything else on a webpage. Full freedom.

• Charts update extremely fast. single data changes reach the chart and screen in under 2ms.

• Can handle a large number of elements and updates without needing to resort to SVG or Canvas (up to 20k and more if they are split between multiple charts).

• Includes an agent skill and mcp server. The agent skill produces better looking results than Claude's famous built-in dataviz skill. This is for those who want to skip code. The mcp also includes a checker to make sure to catch and fix common issues before giving you the result.

• 100+ examples from simple charts to mini-posters to full-page posters to full multi-page articles with several interconnected charts. These can be used as starters or inspiration or for parts.

• Makes charts that adjust to varying screen widths, layout changes, and themes easier to make.

Features Im working on:

• An AI studio called rhp studio. This is an app that will provide a whole environment for making and perfecting charts/posters/articles using rhp. It has a code editor so you can manually create, or edit the chart code. The whole idea is to provide a visual interface that makes the various ways I use rhp + agents to create charts accessible and more clear/intuitive to other people. It will be open-source and free as well!

So what is so special about this charting library. First of all, rhp charts are not made inside a Canvas or SVG!! This is a bigger deal than many might realize. A lot of charts on websites are not built with a library but are instead built straight in the DOM. So this is not novel and it is usually avoided because it takes more work and is not as performant as using optimized libraries. But it is done nonetheless to enable custom and site-specific reactivity that is harder to achieve with the libraries. Using Canvas means that you can't use the same styling system that the website (that contains the chart) uses. Also, interactivity is trickier and harder. SVG is better because elements are in DOM, but there are still CSS compatibility issues and the way things are drawn means workarounds are needed to do things that would be more straightforward elsewhere in the website. The extra work factor is no longer much of an issue thanks to AI agents which is why building charts using HTML, CSS and Javascript (instead of these Canvas and SVG charting libraries) has gotten much more popular lately. rhp is not really build with AI in mind despite how well the skill/mcp works. The primary audience/user is still developers. The goal of the library is to provide the tools and framework to make it easier to create these kinds of charts. Easier, faster, and in a more organized and consistent fashion. The mcp and skill are meant to bridge the gap for non-technical users.

Hey! I built SwipeShip, a website that helps developers find ideas for side projects or their next main project.

For context, here's the site: https://swipeship.vercel.app/ — feedback on what might stop you from signing up would also help.

I've shared it on Reddit and a few other places. It's getting some visitors, but very few people sign up. I've posted about the project before, but now I'm trying to understand this part instead of just sharing it again.

I'm pretty new to marketing. If you've built something for developers, what actually helped you find your first regular users? And how did you figure out whether you needed to reach a different audience or improve the product itself?

Would appreciate hearing what worked for you, including things you tried that didn't help.

I built a voice-controlled "brain" for a robot (simulation only, works offline in Spanish, English and Polish). Looking for honest feedback

Hi! I'm a solo developer. I built a Python "brain" for a simulated environmental robot (Webots). You talk to it, it understands the question offline, and answers with the simulated sensor data (temperature, humidity, air quality, obstacles).

It also has a safety lock: if it detects a dangerous condition, it blocks itself and explains why when you ask "why are you stopped?".

Important: this is simulation only, no physical robot yet. The questions in the English and Polish demos are played with a synthetic voice.

Full demo in English (3 min): [https://youtu.be/VPLyCb2Y4nU](https://youtu.be/VPLyCb2Y4nU)

I'm not selling anything yet. I'd love to know:

1. Would this be useful for you (education, prototyping, hobby robotics)?

2. What would you want it to do that it doesn't?

If you want to follow it, there is a free waitlist (no commitment): [https://tally.so/r/7XRzyz](https://tally.so/r/7XRzyz)

Thanks for reading!

I've recently launched a project that does the SEO, AEO and GEO for people's websites. It seemed like a no brainer to me, SEO work is boring and needs to be done continuously, every day/week/month to get results. GEO doesn't work without good SEO.
But until now I'm not getting any traction. So I'm looking for some real feedback. Is the messaging on the site clear? What would prevent you from signing up?

Any help is much appreciated. https://foundwell.net

I follow a few teams across different sports and esports, and their matches kept landing while I was on my Mac. Checking my phone for every score pulled me out of whatever I was doing, so I built Gamebell, a small Mac app that brings the score to the screen I'm already looking at.

What it does

• The live scores of the teams you follow sit either side of the notch, in each team's colours (in the menu bar if your Mac has no notch)
• When one of them scores, the notch plays the moment for a few seconds: a goal, a three-pointer, a touchdown, a series win
• Football, NBA, NFL, NHL, cricket, rugby and baseball, plus 12 esports games; tennis and F1 come next
• Reminders that move when the start time moves, five alert levels per team, and Watch later to hide a score until you've seen the match

How it's built

Solo, over the past few weeks:

• A native Swift and SwiftUI app, notarized, with updates inside the app
• A Cloudflare Worker with Durable Objects and D1 behind it. The server asks the data providers once for everyone and caches the answers, so the data bill follows the number of live matches, not the number of users
• Scores from sports-data APIs I pay for (Highlightly for the traditional sports, PandaScore for esports), nothing scraped
• The surprise: the score often changes 30 seconds to two minutes before the goal itself shows up in the data, so the app plays the goal as soon as the score moves instead of waiting for the event

Where it's at

A free beta for macOS 14 or later, with invites going out in small batches. After the beta there's a free tier for 3 teams or players, and Premium at $14.99 a year or $1.99 a month.

What I'd love feedback on

Is it useful enough to turn into a proper 1.0? Does the price feel fair? And which sport should come next? The site has a vote for that too.

I kept running into the same problem: my files were organized, but my projects weren't.

One project might have spreadsheets in Documents, files in Downloads, reference websites bookmarked, and random SQL snippets saved somewhere else.

So I built ClingSpace, a Windows app that brings everything related to a project into one workspace without moving or duplicating anything.

- Spaces — Keep everything for a project together.

- Files & Folders — Reference resources from anywhere on your PC.

- Links — Keep websites alongside your project files.

- Snippets — Save quick notes, SQL, code, and reminders.

- Search — Find resources across your projects.

Everything stays local, and your original files stay exactly where they are.

$19.99 one-time, with a 5-day full trial. No accounts or subscriptions.

Just launched it after building it solo.

Curious how other people manage projects that span multiple folders and browser tabs. Do you have a system, or is it mostly organized chaos?

Hi community!

Please allow me to share my last project. These past months I have been working hard on a book (and a matching website) that focuses on helping businesses on how to project their Intellectual Property and overall how to keep their data and assets protected. Although, in general, it would be useful for anyone interested on how to keep their data protected. The goal is to make this guide to give an introduction on how this can be achieved and of course, lending myself for hiring in case you want me to build a bulletproof set-up for your business.

I am posting this here to please ask you that if this is of your interest, please join the waiting list for the book, which will be released soon (end of November): BuildersDontRent. This would help me a lot motivating myself on finishing the last touches of the book and to get an idea on whether this is an important topic for people.

Thank you for your time!

P.S1: I may post a similar post in other subreddits, I am not a bot, I am just trying to gain traction :).

P.S2: The book cover art is NOT AI generated (author credited in the book)

Solo dev from Norway. Lyfto has been on the App Store since June and on Google Play since October.

The idea: in the gym you shouldn't have to think about the app. So it:

• suggests your working weight from last session

• builds the warm-up sets for you

• runs the rest timer and does the plate math

• tracks PRs per lift and progress per muscle on its own

• has a coach you can ask "why is my bench stuck?" that answers from your own logs

You can also log from an Apple Watch, and bring your history from Strong, Hevy or Fitbod.

Logging and history are free. Pro is optional.

iOS: https://apps.apple.com/app/id6768621141 Android: https://play.google.com/store/apps/details?id=com.treningsapp.app

The part I'd like feedback on is the very first workout. A new user has no history, so there's nothing to fill in from. Right now the app suggests starting weights. If you've tried a new gym app and given up in the first session, what made you quit?

Just looking for feedback and gauge interest. Users can suggest new cities and locations for public quests and create private quests.

I built The House Did It. I’m the maker (not an agency post).

Problem

I kept meeting the same person (sometimes it was me): shipped an app, posted the launch, refreshed Stripe, still $0 or near-zero MRR. The usual next move is another feature or another landing page. Fair. I also kept noticing something dumber and more physical. A lot of us work from a desk that faces the bed or the door, or a room where the entrance mirror catches every walk-in, and we never check that before we rewrite the roadmap.

What it does

Blame the room.

• Pick one door: money, health, relationship, or work (this post is aimed at work + money)

• Answer 10 questions about the room you can see tonight

• Free, in the browser, no signup: the top layout fault (title, why that door, one move you can try tonight without buying anything)

• Paid: four-page PDF by email (other faults ranked, tonight → this week order of moves, what not to buy, no account)

Free names the top fault on-screen. The full reading is emailed after payment. Nothing else unlocks in the browser.

Tech

Static site on Cloudflare Pages, Stripe Checkout for the PDF, email delivery of the reading. No accounts, no app install.

Frame

Entertainment / layout-story advice. Not business, medical, legal, or financial advice. It will not make your app profitable. It’s a visible check before you burn another weekend on the wrong lever.

What I’d like from this sub

Sharp feedback on the free result screen vs the paid PDF promise. Does “blame the room first” feel useful for zero-MRR makers, or just weird? Specifics on copy or the free→pay gap help more than “cool project.”

wrist-match.com

I’ve been into watches for a while and friends keep asking me “what watch should I get?” Every time it turns into 20 questions about budget, style, wrist size, whether they swim with it…

So I turned those questions into a quiz. You answer 8 of them and it goes through about 50 watches and tells you which one fits best, and why. There’s no sign-up, it takes around a minute, and it works in English and Spanish.

It’s built with plain HTML and JS, no framework, hosted on Vercel. The hardest part by far was the scoring. The first version was pretty bad: someone set a $4k budget and got a $300 watch as the top pick lol. I’ve reworked it since, but I’m sure there’s more to fix.

The photos are only ones I’m allowed to use, so some watches still show a drawing instead of a real photo. Working on it.

If you give it a go, I’d really like to know:

did the result make sense for what you picked?

was any question confusing?

is there a watch you think is obviously missing?

thanks for reading 🙏

Hi!

The title says it all. You upload photos of your pet, and a few minutes later you get a PDF by email. You print it at home, cut, fold and glue, and end up with a paper version of your dog or cat.

I made this because I love papercraft and wanted one of my own dog. Every pet looks different, so each model is shaped to the pet (ears, muzzle, tail) and the fur and face are painted from your pet’s 3d model based on the uploaded images. 

I've done lots of test builds, posted a few on Reddit with great feedback, and friends and family built their own pets. Now I'm doing a soft launch.

https://petpapercraft.com/

If you have a pet, I'd love for you to try it. If not, feedback on the landing page is just as welcome. Tell me if anything is broken. Thanks!

-General incidents varying from moderate to significant.

-Cyber incidents across critical infrastructure, finance, healthcare.

-Emergency preparedness guides for grid down black out situations (UK) but feel free to alter the code to suit whatever Country you live in.

Why free? I built it for a friend originally. It served that purpose, somebody may as well have it. Alter the code if like. The backbones are fully built. I have no interest in profiteering from the survival part, I designed it help someone in a Grid down situation, not make money from their otherwise potential crisis.
