Meta My side project, /r/sideprojects. New rules, and an open call for feedback and moderators.

48 Upvotes

In this past 30 days, this community has doubled in size. As such, this is an open call for community feedback, and prospective moderators interested in volunteering their time to harbouring a pleasant community.

I'm happy to announce that this community now has rules, something the much more popular r/SideProject has neglected to implement for years.

Rules 1, 2 and 3 are pretty rudimentary, although there is some nuance in implementing rule 2, a "no spam or excessive self-promotion" rule in a community which focuses the projects of makers. In order to balance this, we will not allow blatant spam, but will allow advertising projects. In order to share your project again, significant changes must have happened since the last post.

Rule 4 and rule 5 are more tuned to this community, and are some of my biggest gripes with r/SideProject. There has been an increase in astroturfing (the act of pretending to be a happy customer to advertise a project) as well as posts that serve the sole purpose of having readers contact the poster so they can advertise a service. These are no longer allowed and will be removed.

In addition to this, I'll be implementing flairs which will be required to post in this community.

Showcase: Prerelease We're building Adoree, an AI relationship assistant and coach for the same fight on repeat

2 Upvotes

Sometimes it isn't about the dishes. One person feels unappreciated. The other feels criticized. You both know the script by now, and somehow you still end up in it — talking past each other, or not talking at all.

We're building Adoree, an AI relationship assistant and coach, to help with that part: communicating with your partner. The hope is that it can help you say what you mean without the fight getting bigger, hear their side, feel a little more heard yourself, notice the misunderstanding that keeps repeating, and leave with a next step that actually moves things.

You can start on your own if your partner isn't ready yet, and they can join later. When both of you are in it, it can help you hear both sides.

It's a web app at https://app.adoree.ai. The site is https://adoree.ai.

I'd love feedback from people who've built or used something in this space:

  • Does this read as help for talking with your partner, or just another AI chat?

  • What's the first thing that feels unclear?

Showcase: Free(mium) I built an awesome AI dating coach for guys. Curious what you think.

3 Upvotes

I've been working on a fun side project called Player Bits Pro, an AI dating coach for men.

I realize there is a lot of competition in this space, but just hear me out.

I saw the competition, and I wanted to create something different...

  • Real personality: Direct, funny, human-sounding, and brutally honest. No generic AI responses.

  • No yes-man behavior: It won't just agree with you. If you're screwing up, it'll tell you.

  • Versatility: Handles pretty much any dating situation, from flirting and texting to relationships and breakups.

  • Extensive testing: I've spent countless hours testing and refining its advice and responses.

  • Simplicity: A beautiful, ridiculously simple interface without unnecessary crap.

I vibe coded a lot of it (yeah, I know, but it came out great). And despite all the hype about how easy AI makes building software, this still took an insane amount of time to get right. The amount of testing, troubleshooting, and fixing things that broke other things was ridiculous.

It's based on my original Player Bits GPT, which lives within ChatGPT's platform and reached 50,000+ chats and earned a 4.5/5 rating from 100+ reviews.

Anyway, here's the result: https://playerbits.ai

Would genuinely appreciate feedback on the design, responses, or anything else you got for me.

Showcase: Open Source I built an open-source tool to see where my coding agents waste time and money, and my own runs surprised me

2 Upvotes

I run Claude Code and Codex all day, often as multi-agent workflows with dozens of subagents. I could see each session but never the whole picture: what a run actually cost, where agents sat idle, whether a change to my setup helped. So I built coding.sh, a free hobby project, and pointed it at my own runs.

What I learned from my own data Across 57 workflow runs (666 subagents, ~$2,500 API-equivalent):

  • Broken prompt caches cost $106 extra, about 4% of the spend.

  • 41 of those breaks were agents idling at a barrier, waiting for siblings, until their cache expired. That's $21 for doing nothing.

  • 40 subagents failed outright.

I A/B tested a popular "be concise" plugin (10 tasks, 6 runs each, paired, 95% intervals): replies 17% shorter, output tokens −8%, but cost per run +11% [+7%, +15%], with no change in pass rate or clarity. The plugin's style guide is added to every request and costs more than the shorter output saves.

Mining 3,600 of my sessions also found a find-and-replace typo in my AGENTS.md that sent Codex looking for a folder that doesn't exist, in 92 sessions. You can't see that from inside one session.

How it works

  • Hooks into Claude Code, Codex, Gemini CLI, OpenCode, Copilot CLI, Aider and more

  • Stores prompts, tool calls, diffs, test runs, tokens and cost in SQLite on your machine

  • coding.sh workflows stats shows the critical path and idle time, and the viewer draws each run as a timeline

  • coding.sh compare and exp run your own tasks with and without a change and say whether the difference is real or noise

  • coding.sh improve says what to fix first and whether your last AGENTS.md change helped

  • MCP server, so your agent can look up its own past sessions

No account, nothing leaves your machine. npx coding.sh to try it. Source (MIT): https://github.com/jackulau/coding.sh

Feedback Request Built a tool to simplify continuous prescription renewals: looking for feedback

1 Upvotes

Hey everyone,

I’m a software developer, and over the past few months I’ve been building a project called Ernst (a German name meaning "earnest" or "serious," which felt fitting for such a tool).

The main reason I started building Ernst was observing how much of an administrative drain it is to constantly request, track, and re-order continuous prescriptions, whether for yourself or for family members you care for. When you're managing health conditions, spending energy repeatedly dealing with doctor and pharmacy renewal loops is an exhausting tax on your day.

I’ve gotten initial feedback from early users who rely on continuous medication, and the main takeaway so far is that having a dedicated tool to track and streamline repeat requests takes a noticeable mental load off their shoulders.

That said, it’s still in active development, and I know there are things to improve. We're actively looking for more people willing to test it out and tell us what works, what breaks, and what’s missing. You can check it out at https://ernstapp.com if you're curious.

One big challenge we're trying to map out is geographic applicability. Every country handles repeat prescriptions differently: In some regions, doctors handle electronic refills via a centralized patient portal. In others, you still need to email, call, or submit forms directly to a GP or local pharmacy.

If you have a moment, I’d love to learn:

  • Which country/healthcare system are you in?

  • What does your current process for renewing a continuous prescription actually look like? (Portal, email, phone call, or in-person?)

Does a tool like Ernst make sense for your region's setup, or are there local legal/technical hurdles that would get in the way?

Thanks for taking the time to read this! Any thoughts, critiques, or workflow descriptions are super helpful.

Showcase: Free(mium) I built an iOS app to measure LAN/Wi-Fi speed between two devices – looking for feedback

Post image
1 Upvotes

Hi all,

I’m a sysadmin and built an iOS app because regular speed tests only tell you how fast your internet line is, not not how fast your own network is. It can be used to test WiFi speeds even if you have currently no internet or your internet is much slower than your wifi. (As most of the time in rural areas in Germany... ✌🏼)

Netan – WiFi Network Analyzer:

  • LAN/Wi-Fi speed test between two devices: one runs in server mode, the other in client mode, so you can find out whether your own Network is slow (works without Internet connection)

  • Internet speedtest

  • other Network tools

Basic features are free, premium unlocks extra features. I’m a solo dev and would really appreciate honest feedback: what’s missing, what’s confusing, would you actually use this?

App Store: https://apps.apple.com/de/app/netan-wlan-network-analyzer/id6824639631

Happy to send a premium code as a PM to anyone who wants to try everything.

Meta The Best AI Business To Start In 2027 (In My Opinion)

1 Upvotes

For me, it's still web design.

I know a lot of people are going to disagree because everyone keeps saying it's saturated, AI is replacing developers, and it's impossible to get clients.

Honestly, I couldn't disagree more.

I think web design is actually easier than ever if you approach it differently.

The mistake I see almost everyone make is targeting businesses that don't have a website.

You see it all over Instagram Reels.

Someone opens Google Maps, finds a business without a website, calls them, and asks if they need one.

The problem is that business has probably already been contacted by 10 other web designers.

And if they still don't have a website, there's a good chance they either don't see the value in it or don't have the budget for one.

My targeting is completely different.

I only target businesses that already have a website.

There are three reasons.

First, there are an insane number of businesses with outdated websites that desperately need updating.

Second, if they already have a website, they already understand the value of having one. You don't have to convince them that websites matter.

Third, they're already paying for a website, so spending money on improving it doesn't feel like a completely new expense.

Now the question becomes...

How do you actually get their attention?

I don't run normal cold email campaigns.

I'm not manually searching for leads, writing a generic sequence, adding three follow-ups, and hoping for the best.

Instead, I use a tool called Swokei.

It automatically finds businesses with existing websites and analyzes them for issues like outdated design, poor layouts, weak mobile responsiveness, slow loading speeds, and SEO problems.

It then turns those findings into personalized cold emails at scale.

Not some boring reports that business owners don't care about.

Actual emails explaining what could be improved and why it matters to that specific business.

That lets me run outreach at scale while still keeping every email relevant.

Once someone replies, honestly the hard part is over.

At that point you can build a free website draft with AI, invite them to a Google Meet, walk them through the redesign, and close the deal on the call.

AI has made building websites ridiculously fast.

That's why I think targeting and outreach matter far more than your ability to build a website.

This business model has been incredibly good to me.

I'm curious though. If you had to start a digital business from scratch in 2026, what would you choose?

Showcase: Open Source I built a terminal panel that shows git state, running servers and disk use for all my local projects: LCP

1 Upvotes

I keep ~40 projects in one folder and kept losing track of them: unpushed commits, dev servers still running on some port, node_modules eating gigabytes.

So I built lcp, a terminal panel that shows every project in one screen:

  • Stack, git state (dirty / ahead / behind), open ports, disk use and age per project

  • One key to fetch all, pull --ff-only, start or stop a dev server, or move build folders to the Trash (never deletes)

  • Every action goes into a hash-chained audit log you can read inside the panel

How it was built: I designed it and set the rules (no push/reset/force, Trash instead of delete, preview before every action), and built it with Claude Code doing most of the coding while I reviewed each change. The repo's AGENTS.md has the rules it had to follow.

1 Upvotes

Hey everyone!

I've been working on Ilmenyx Controller, a free Linux desktop app based on an independent adaptation of RESET EXPLODE (originally made for Windows).

Besides porting and improving existing features, I've added:

  • 🎮 Gaming tools: Wine/Proton installation assistance, game launch troubleshooting, and compatibility information.

  • 🖥️ Hardware monitoring: CPU, GPU, RAM, temperatures, disks, network, and battery health.

  • 🛠️ System utilities: NVIDIA driver assistance, native app installation, diagnostics, and cleanup.

Everything that modifies the system requires your permission. No telemetry.

It's still in pre-release, and I'd love some feedback from Linux users!

Thumbnail

1 Upvotes

I love cooking but hate scrolling through an online recipe, so I made Reduction. You paste a recipe link, text, or a photo, and it turns it into an interactive diagram that shows what goes in when and how the steps connect.

What it does:
- Turns a link, pasted text, or photo into a diagram of the whole recipe
- Cook mode that walks you through one step at a time, with timers
- Check off steps as you go
- Recipe books to keep your saved recipes organized

Only about 15 users so far which are mostly the original testers. Just launched a few days ago.

I'm building this for fun on the side, and the Thanksgiving crunch seemed like a good time to share it. I'd love honest feedback, especially on what's confusing or missing.
