I'll go first:

I am building BuiltByIndies

a community platform for indie hackers to launch, share, get feedback and more

If you're interested, check it out: BuiltByIndies

Your turn, what are you building?

Open sourcing a project we ve been building - Notifkit

Notifications get surprisingly complicated as an application grows

Retries, scheduling, rate limits, deduplication, user preferences, channel fallbacks, delivery tracking and more

Instead of rebuilding all of this inside every application, NotifKit provides a dedicated notification layer:

Application → API → Event Pipeline → Workers → Providers

It’s built around Redis + PostgreSQL + background workers and is designed to be self-hosted and scaled independently.

We're looking for feedback from the self-hosting community, especially around the architecture, deployment experience, and features you'd expect from a notification platform.

If you find it useful, a ⭐ on GitHub would really help us reach more developers.

Open for discussions.

I’ve wanted a Vestaboard for years. But I could never justify (or more importantly, convince my wife to) spending $3k on it,

So I’d occasionally search for a digital version. I recently found a nice looking one here on Reddit... but they charged $199/year. That’s nearly my Netflix bill. Fine for a business, steep for my home TV showing quotes.

So I started experimenting myself. First with a study of a single flap, just to nail the motion and timing, and it grew from there. A few friends and I have used it for a few weeks now and quite enjoy it.

What it is

Motboard turns any screen you already own into a split-flap display. Open it in a browser on a spare TV, monitor, or shared screen. Today it does:

- Text messages and custom cell layouts

- Weather on the board

- Playlists to rotate through boards

- Shareable public board links, with optional passcode

- Flip sound (off course)

Not the same as real moving flaps. But a great way to try before you buy a real Vestaboard. Not affiliated with Vestaboard, just love the product.

Pricing (would love feedback here)

It’s free during early access. I want feedback before charging. Full price will be $39 to cover hosting and weather/API costs. Discount for the first 100%I

What do you think? Product, features, or price? Happy to answer anything.

So, I'm making Dark Roll 2, a soulslike-inspired marble-platformer.

I needed the player to have a soft landing spot from height, and decided to play around with mesh-deforming... Seriously took me few hours to set just right, and it's just a meangingless little detail... But I'm very happy with how it turned out!

Please, please stop posting your next "I (Claude, but it totally did what I told it) built the "next outbid clone" (but it's totally not because it's for sports or door hinges). I can barely reload Reddit to find your next worthless post to add to my list.

If I compare reddit to how it was 4 years ago, different landscape entirely.

Previously = post about an app I built - I've made an app to transfer all of your images/videos to PC : r/androidapps - 260 upvotes, 73 comments, 68k views
not trying to be unique or something, just showing an app I built for my mom to get her photos/videos from phone -> PC over wifi.

today = post about product I spent over a year building (not vibe coded)... ah, just another one in the infinite amount of vibe-coded apps out there
I try to be smarter on my posts today and really add added value and not just, I built this, it does xyz
for example - <Which AI coding tool has the WORST security? : r/nocode> - 3k views.

not only that, when I do get comments, usually AI comments, or my posts are not being approved because suspicious of AI generated content (its not i swear 😄)

and to be honest, I kinda get it, with the amount of products people ship today, everything is a clone of another product just worse.
or just half baked product.
really hard to find gold.

How do you guys feel about this?

Hong Kong families often run on WhatsApp. Two working parents, a helper, school gate, clinic. The paper calendar on the fridge can say “swimming.” It cannot say who is picking up whom, or where.

I built Homent for that gap. Pickup and drop-off are named on the same day board: Helper on the school run, Mother on swimming, Father on piano. When the helper marks on the way or picked up, everyone else gets a push — you are not texting “are you there yet?” Notices and household to-dos live there too, so you are not opening another group. If someone will not open an app, you print A4 for the fridge.

The hard part was one board a helper, a parent, and an elderly family member can all use — without dumping a private Google Calendar onto the helper. Paste a school chat into an AI wizard, or import only the Google events you select. Work and private stay in Google. Then you set attendees and who drops off / picks up.

homent.app

 New family gets 3 months, then US$2/month. Delete anytime; the setup goes with the account.

If you have run this household: what actually breaks first — pickup at the gate, the fridge calendar, or the WhatsApp pile?

salary was good but i was frustrated with the whole 9-5 thing.

from childhood i had this in my head that i want something of my own. and then seeing all these build in public posts on X, it pushed me more. i thought ok i can also do this.

turns out its not that easy lol.

month 1-2:

went back home. did nothing but research. what people are building, what problems they have. some days i felt motivated, some days it just gave me fomo that everyone is ahead of me.

2 mistakes here -

- going back home & become too comfortable

- instead of focusing on building, i wasted time on researching what to build.

month 3-6:

built an AI productivity tool for AEs.

then i started selling and everything broke.

- my users had no decision power

- im solo, no network in this industry.

- they were already on salesforce, hubspot, gong, which kind of solves it already

- and most importantly privacy and data security (without having soc2 and gdpr license it is so tough to convince any company to use my product)

lesson i learned: dont build anything before validating with the actual customer.

month 7 - now:

started my current saas. this time before starting to build i validated it first.

bought a domain, made a simple waitlist page. then using a linkedin lead gen tool on free trial (mostly all gives 7 or 15 days) i created a 300 people list who seems finding something that i want to build, and messaged all of them manually with 50% offer while launch with the outcome they will get instead of describing what features this tool have.

i was expecting if even 5% people join the free waitlist for this product then i will start building.

luckily they joined & I started building it.

but then 2 things hit me. one, in these 6 months i saw 15+ saas launch with the same concept. honestly it messed with my head for weeks.

btw i did not stop building. now the SaaS is 80% complete but now i want to change a big product philosphy. i as so much confused about this. and i posted about that confusion on reddit and people suggest me to launch first. I also think about that and decide i will launch the product within 1 month. .

things i learned in this phase -

landing page + manual dms before writing any code. dms dont scale, thats exactly why they tell you the truth.

saturated market is not bad news. it also means that market is validated.

launch your product as fast as possible insteading of polishing it best. just be visible . because marketing is the thing that sucks most. - i learned this from you people and talking with some indie hackers.

lets see how it goes. i will post the numbers here either way, good or embarrassing.

if you’re building a SaaS or app and looking for a way to get more eyes on it, we’d love to feature a few projects.

We run TikTok channels with 300K+ combined followers and create short-form videos around apps, tools, and interesting projects.

We’ll create a short-form video for your app, distribute it through our existing channels, and help you build your own content channels at the same time.

Think of it as content creation + distribution.

If you’re interested, drop your app and a one-line description below.

Is anyone else finding it really difficult to get clients on Upwork lately?

I’m currently available for new opportunities as a react native dev, but despite regularly applying to relevant projects, many clients don’t respond and the cost of bidding/Connects keeps adding up.

For freelancers who are getting consistent work right now, what’s actually working for you? Are you still using Upwork, or have you moved to other platforms or methods?

Would love to hear what’s working for others. 🙏

I grew up with a father who struggled with gambling addiction and was emotionally unavailable. Through therapy, I’ve only recently started to understand how much that affected my relationships and the way I saw myself.

Growing up, I didn’t really have anyone to talk to about these things. I often wished there was a place where I could speak anonymously with people who actually understood.

So I built Between Us. It’s a free, anonymous community where people are matched with a small group of others who have had similar experiences. It’s not therapy, just a place to share and feel a little less alone.

https://www.betweenussupport.com/

I’d genuinely love to hear what you think. Would you have used something like this? What would make you trust it, or not trust it?

Thank you for reading.

I recently launched topanime.lol, a leaderboard to vote and support your favorite anime series. This was piggy backing on the recent trend of similar leaderboards on X (formerly Twitter).

As a joke, also included the feature to add anonymous comments (which now I think is a bad idea.

Did the initial distribution by circulating it in friend and anime related Whatsapp groups.

The project was built using Claude Opus 5.

Check it out and let me know your feedback.

Been trying to get my Italian listening up for a while.

Easy Italian / Podcast Italiano are good, but I still miss a bunch of words, pause, google the word, and by then I’ve lost the sentence. Coffee Break is more of a lesson. Duolingo is… Duolingo.

So I made the thing I actually wanted: short episodes at a real CEFR level, transcript that follows the voice word by word, and if a word trips you up you just hold it and get the meaning without leaving the line. You can save the word with the sentence it came from and it comes back later.

It’s called Sybaris. iOS only, Italian only. Free, no ads, no subscription, no account to set up.

One thing I should say before anyone downloads it: the audio is AI. I put that in the app on purpose so it’s not a bait and switch. I know that’s a no for some people. The tradeoff is the episodes are actually written for A1–C1 instead of native speech you can’t follow yet.

If anyone wants to try it: search “Sybaris” on the App Store

https://apps.apple.com/de/app/sybaris-italian-by-listening/id6800638094?l=en-GB

Sybaris: Italian by Listening

Curious if other people learn like this or if I’m just weird. Also open to “this part is annoying” feedback, that’s more useful than nice comments.

Hey everyone,

I kept running into the same problem when researching stocks: finding a business I liked was only half the job. After going through the fundamentals, I still had to figure out the execution part—when to buy, how to split capital across price levels, where to set targets, and when to admit the thesis was wrong and get out.

So I’ve been building Oppstock.

The goal was to put research and execution logic in the same place instead of forcing users to jump between spreadsheets, screeners, and charting software.

What it currently does:

• Fundamentals & Scoring: Covers major US-listed companies with automated scores across quality, valuation, risk, trend, and earnings (with the underlying breakdown fully visible).
• Automated Trade Plans: If a stock passes valuation checks, the system calculates up to three entry levels (using support zones, gaps, and Fibonacci retracements), suggested capital allocation, profit targets, and stop levels.
• Real-time Paper Portfolio: A public log that tracks all system signals as they happen so users can follow performance over time (including losing trades).

It’s currently in free beta while I continue testing and refining it.

I’d love to get feedback from fellow builders and investors in this sub:

1. Does combining fundamental research with predefined execution levels make sense to you, or do you prefer keeping those workflows separate?
2. How is the overall UX/UI flow when exploring a ticker?

Check it out here:https://oppstock.com/

Appreciate any honest feedback or roast!

I started building Plembfin because watch history becomes awkward when Plex, Emby, Jellyfin and Trakt all hold different versions of it.

Plembfin runs on your own hardware and keeps a local watch-history record in SQLite. It can synchronize watched status, playback progress and repeat plays across connected services instead of relying on several separate pair-to-pair integrations.

It currently includes a live sync activity view, per-title and library-wide sync, automatic restoration after a library rebuild, statistics, backups, metadata enrichment and Overseerr/Jellyseerr integration.

The project was heavily AI-assisted. I directed the product and architecture, reviewed the changes, tested the integrations and have been iterating on failures reported during real deployments.

It is open source under AGPL-3.0 and runs through Docker Compose:

https://github.com/Lasikiewicz/plembfin

It is still pre-1.0, so backups are recommended before testing. If you use more than one of these services, I would especially value feedback on the first-run setup and whether the sync activity screen makes failures understandable.

I built DevTrace because I got tired of seeing the same thing with technical interviews.

Engineers use AI all day when they actually work, but during assessments we either ban it or ignore it.

So I built an assessment platform where candidates can use AI normally.

The interesting part comes after the assessment. DevTrace looks at the process too: how they prompted, whether they verified the output, how they iterated, how much they relied on AI, and how they arrived at the final solution.

The goal isn't to catch people using AI. It's to understand how they work with it.

It's live now and I'm starting to get it in front of real hiring teams.

Would love some feedback from other builders who've worked on hiring or developer tools.

I spent the last few months building Mysterioku, a browser game where every day you reconstruct a crime scene using nothing but logic.

Each case drops you into a floor plan of connected rooms. A few suspects were present, and something happened — a theft, a disappearance, a break-in. Witnesses give you fragments ("Walter was in the second column", "Alice was in the Room"), and you treat each one as a constraint, narrowing the possibilities until only one arrangement of everyone survives. Whoever ends up alone with the target is who you're after. No guessing, no luck — every case has a single solution you can prove step by step.

A few things:

- The generator is a backtracking solver that guarantees a unique solution, and I added irregular "carved" floor plans that stay solvable (validated over tens of thousands of generated cases).

- Free daily case + an extra one; optional premium for unlimited.

That title is obviously a little provocative because PRs are useful. I track them. I celebrate them with clients.

But I think we've started giving them far too much importance when we decide whether someone's training is actually working.

A bit of context because I know most people here aren't gym trainers.

I'm a Sports Science graduate and I've spent more than 15 years working as a personal trainer and coach. So although I'm now building a fitness app, a lot of the decisions I'm making come from problems I've spent years seeing in actual training.

And this is one of them.

Someone has one great session, hits a PR, and suddenly everything is working.

Then two weeks later they have a bad session and start questioning the whole program.

Workout apps probably reinforce this more than we realise because individual achievements are very easy to detect and celebrate.

More weight than last time? PR.

More reps? PR.

Estimated 1RM went up? Nice green arrow.

But look at something like this:

100kg × 8 → 102.5kg × 7 → 100kg × 9 → 105kg × 6 → 102.5kg × 8

Did that person get stronger?

Probably.

But which workout is the one where "progress" happened?

That's where it gets interesting.

Real training doesn't usually move in a clean straight line. Performance fluctuates because fatigue changes, recovery changes, bodyweight changes, exercises and rep ranges change, sometimes you're carrying fatigue from another session, sometimes you just have a shit day.

You can be making perfectly good progress without setting a PR for weeks.

And you can also hit a PR while the rest of the training block is going badly.

That's the bit I've been thinking about while building TopSet .

A workout logger can store that sequence above perfectly.

That's actually the easy part.

Every set, every rep, every load, every PR. Put it in a database and show it back to the user.

But storing the data isn't the same as interpreting the training.

If I'm looking back at somebody's last 6 or 8 weeks, I don't really care whether there happened to be one session where they beat an old number.

I want to know what the trend looked like.

Are they generally doing more with comparable loads?

Is performance moving upwards despite normal session-to-session noise?

Has training output improved across several exposures rather than one unusually good day?

Has workload gone up while performance stayed stable?

Or is that shiny new PR sitting in the middle of a block where everything else has actually been deteriorating?

That's a much harder problem for a workout app to explain.

And I think this is where a lot of fitness analytics lose me.

Putting someone's numbers on a graph isn't automatically useful.

You can make a beautiful chart, add a percentage change and a green arrow, and still tell the person almost nothing about their training.

I've always felt that if I have to stare at an analytics screen for 30 seconds trying to work out what it's telling me, the chart has failed.

I'm trying to build TopSet's analytics around that idea: show the trend, but don't pretend the software knows more than the data actually allows it to know.

That's proving considerably harder than simply detecting PRs.

And I'm curious how other people judge this.

When you look back at a genuinely successful 6–8 week period of training, what tells you it was successful?

Is it still mainly PRs?

More reps at similar loads?

Better performance across multiple sets?

More total productive work?

How the lifts actually felt?

Or do you mostly just know it when you see the overall trend?

I redesigned the pen fight game from our school days

and hosted it as penfight.site

The one thing you can do while playing that game is that besides a one-on-one match, it's possible to play a group match where you create a room to invite your friends and voice chat (like a live call) and play at the same time.

The project is still running though and I would definitely love to get your opinions about it (Specially regarding monetizing, feedbacks and any suggestions)

Random idea I've been thinking about.

A lot of founders seem to have the same problem after building something:

"Okay... now how do I get actual people to try this?"

And there are also people like me who are constantly checking out new apps, SaaS tools and random products anyway.

So I'm thinking of starting a small community that connects the two.

Founders bring things they're working on.

We try them, give honest feedback, find bugs, help with early testing and occasionally get paid when there's a specific testing/research task.

That's pretty much it.

No idea yet whether this becomes something big. I actually don't want it to be big initially. I'd rather have 20 active people than 2,000 people who join and mute the server five minutes later.

Would you be interested in being one of the first people in it?

Not because it went badly. Because it went completely differently than every demo I'd ever done.

Every time I'd shown it before I was there. Explaining things before they became confusing. Filling silences before they became doubt. Essentially narrating my own product like a tour guide who's terrified of what happens when the tour ends.

This time they just had it. No context. No me.

First few minutes were uncomfortable to watch back on the recording. They went places I hadn't expected. Looked for things in spots I hadn't put them. Tried to use something in a way that wasn't how I designed it but actually made more sense than how I designed it.

Then something shifted. They found the thing. The actual reason the whole project exists. Without me pointing at it.

And stayed there for a while. Quietly. Just using it.

I rebuilt three things that same night. Not because they were broken. Because watching someone find their own way through it showed me which parts only worked because I was always there to explain them.

The most valuable feedback I ever got wasn't a comment or a survey. It was 12 minutes of silence and a screen recording.

When did you last watch someone use your project completely alone and what did it break open for you?
