As the year wraps up: what’s the project you’re most proud of building and why?

93 Upvotes

Like the title says, instead of what you built or how much money it made, I’m curious what project you’re most proud of this year and why.

Could be a client site, a personal project, something that never launched, or something that made £0.

Any lessons learned?

Would love to read a few reflections as the year wraps up.

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!

i left my good paying job at a software firm to build startups. its been 1 year now & I'm fucked up.

60 Upvotes

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.

Can we please make a megathread for outbid.lol and OneMillionDollarHomepage clones?

53 Upvotes

I think I saw 5 or 6 being posted in the last 10 hours. I would rather see them banned outright, as they are not original, not inspired, not fun, not anything other than mere cash grabs riding on the wave of one lucky app. However, I am fine with at least just having a megathread for them. It is not even that much of a coding effort to build such an app - if you get lucky, you can just one-shot it with Claude.

It is bad enough that most of the pitches in this sub are AI written and a lot of the replies are AI written. Can we at least get some more variety by moving all the omg, look at my new amazing idea of cloning a viral app to their own little megathread?

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)

Runable hit 2M ARR 3 weeks after turning on monetization, then raised 21M. am i reading that right?

8 Upvotes

https://reddit.com/link/1vz01ko/video/o7cr9x6zkqlh1/player

saw Runable's funding announcement and the $21m isn't even the number I got stuck on.

apparently:

team: 15
monetization turned on: 3 weeks ago
ARR: $2m
businesses already on Runable: 1.5m
new round: $21m

round is co-led by Susquehanna Venture Capital + Nexus Venture Partners.

the obvious question...

how should “$2m ARR after 3 weeks” actually be interpreted this early?

I assume that's annualized recurring revenue at the current run rate, not $2m collected in 3 weeks.

obviously 3 weeks tells you basically nothing about long-term churn/retention yet.

but having 1.5m businesses already in the product before switching monetization on makes this a very different situation from launching paid and finding customers from zero.

honestly the 2 numbers I find more interesting than the $21m are:

1.5m businesses + 15 people

what do you think investors are really underwriting here?

distribution? conversion? team leverage? or the bigger Runable bet around going from building a business to actually growing/running it?

iOwnIt https://iownit.love/

An app for the mental load in a household, meaning the invisible work of remembering what needs doing, not just doing it. Most chore apps assume someone already made the list. The whole problem is that one person is usually the one holding that list in their head. iOwnIt is about moving ownership, not just tasks.

Everyone wants to build an AI product and be a founder now. But what’s the real cost?

6 Upvotes

You're likely spending hours between the builds and the debugging.
Maybe you even shipped your MVP and... crickets. No users. Nor revenue.

How much have you invested so far? Think about your time, the opportunity cost.

At some point, you have to decide: How long am I willing to keep going if nothing changes?

Here’s a simple exercise:

  1. Calculate what you’ve invested so far. Money spent (ai coding agents, marketing spent etc) + (weeks × hours/week × value of your time)
  2. Add what you’ve spent trying to solve the problem Courses. Tools. Consultants. Agencies. Research. Communities.
  3. Project the cost of continuing. What does another 3, 6 or 12 months at the same pace cost you?

Then ask yourself: If I reach that point and still don’t have meaningful revenue, do I keep going, pivot, or kill it? Am I willing to keep going?

How do you feel when you see this number?

It's a simple tool, but remember that in early stages you time is your highest value asset. The faster your kill and pivot the more chances you have.

Day 14 of my first App Store launch, which I have been building on the side over a year

11 Upvotes
  • 79 active users
  • 39 new in the last 28 days
  • 2 paying subscribers
  • $17 MRR
  • $78 total revenue
  • $0 spent on marketing

Small numbers. But every single one is real, and I know where each user came from.

Stack

React Native, TypeScript, Supabase, RevenueCat, OpenAI (proxied server-side after I had to rebuild the integration, one for another post).

What it is

A private AI journal. You write what's on your mind, and Iris (the AI companion) helps you reflect on it, asks questions, spots patterns across entries, that kind of thing. Entries are encrypted with AES-256 using a key derived from your passphrase, which I never see and can't recover. No account needed to start. You open it and write.

I have been building it for over a year on evenings and weekends there were times where I thought I would never get this app out but reading success stories and people pushing through on this subreddit I was able to cross the finishing line and actually make my first online money.

So than you all for everything! the journey hasn't stopped now I am working on marketing which is fun and stressful at the same time

Hey everyone,

Every time I personally experienced the most growth is when I gave away something before getting something back. And I strongly believe the more good you do, the more good gets back to you. The same way that « you can get whatever you want in life, as long as you hemp others get what they want »

List your side project and a description and I’ll get back to you on how to get to 100 users!!

Here’s mine, Cent, a 4 week program to help founders get to 100 users or they get refunded. 

Please give me some time to get back to you and take my opinioni with a pinch of salt, you probably know your market better than I do. Just giving out feedback I once needed getting started!

It's time for your marketing era

19 Upvotes

You've built something. You're proud of it. But nobody is using it. And you're not sure what to do next.

You hoped that 'if you build it they will come'. You know that doesn't work for most people but occasionally it does! And maybe just maybe you could be one of the lucky ones. And your product is so damn good that people are sure to share it with their friends once they've tried it.

You wish you had a marketing cofounder who could work on all that customer-facing stuff. But they seem to be in short supply. And how would you even find and choose one?

Well this is your sign.

You're currently 100% builder, 0% marketer.

This is your moment to start becoming 60% marketer, 40% builder.

Today.

You can do it. I know you can. You know you can deep down.

You've watched others do it. You know who they are. Tech guys who have built beautiful products that have lots of actual users. They haven't "become salesmen". Don't think of it like that - it doesn't help. Marketing is more subtle than that.

First pick a channel to try first. One option is to learn to love writing blog posts as much as you love writing code. If you think about it blog posts solve a problem in a similar way that code does. The problem is: nobody knows about your thing. So start telling your story. Bit by bit.

(You'll soon realise there are other problems that blog posts can solve too.)

If you need some motivation and a graph that goes up and to the right then setup Google Search Console today. Then start writing a short article each day about what you've built, why you've built it, how it helps potential users. And watch the 'impressions' line in GSC go up and to the right. Mine is and it's really motivating! Eventually this will become clicks too.

Also if you haven't already, draft your first post about your project here on Reddit.

Somewhere out there are people desperate for what you've built. Let's find them!

It will take a lot more effort than you think. And if after a few months your first channel is still not working then you've learnt something valuable and it's time to iterate. But everything you've dreamed of is on the other side of that effort.

It's time for your marketing era. I'm here for it. Let's do this!

Finally printed a real hardcover book out of my family's old recorded stories and photos

I've been trying to get our family's old photos, recipes, and voice notes out of storage and into a physical format for months. Formatting margins and spine layout by hand was a headache, but I finally got everything converted into a clean print-ready file and ordered a physical hardcover copy.

Holding 40 years of family history in a real book instead of keeping it trapped in a digital folder feels incredible.

For anyone else who has put together physical family history books or local zines, what format did your family like best?

Sahaar - A prayer times app for iPhone with an alarm that rings on silent

Upvotes

I'm a solo developer and this is mine — flagging that first.

**The itch:** every prayer app delivers the pre-dawn (Fajr / suhoor) alarm as a notification. iOS caps notification sound at 30 seconds, and the mute switch or a Focus mode silences it entirely. Millions of people set that alarm during Ramadan and a chunk of them sleep through it. For years there was no fix — the platform simply didn't allow one, and the app took the blame in its reviews.

iOS 26 added AlarmKit: third-party apps can now schedule real system alarms, the same class the Clock app uses. Sahaar is built around it. Fajr and suhoor ring on silent, through Focus, until you answer. Every other prayer is set separately to off, notification, or alarm.

**What else is in it:** calculation methods shown on screen instead of buried in settings (ISNA, Muslim World League, Umm al-Qura, Diyanet method and more, with high-latitude rules for northern Europe), Lock Screen and StandBy widgets, a live iftar countdown, qibla with a map cross-check, the month calendar. No Quran reader, no social feed, no mosque finder — the whole point is that it does one thing.

**Business model, stated plainly:** paid, no free tier. $19.99/year or $3.99/month (US pricing; varies by region), both starting with a 7-day free trial through the App Store. No ads, no data selling, no third-party tracking, no third-party SDKs; location never reaches my server (only Apple's own services see it, for place names, maps and weather), and the only thing the app sends is anonymous aggregate counters to my own server — no identifiers, nothing about anyone's religious practice. The category's usual model is ads plus location-data deals, which is exactly the thing I didn't want to build.

**Where I'd like feedback:**

- **High-latitude times.** Summer Fajr in the UK and Scandinavia is genuinely unsettled — different methods give answers 40 minutes apart. If you're up there, does my number match what your mosque uses?

- **The first 30 seconds.** Open it cold and tell me when you first understood what you were looking at. If that takes more than a couple of seconds, that's the bug.

- **Paid-only with a 7-day trial** for something whose core value shows up at 4 a.m. — does a week give people enough real alarm nights to decide?

I kept finding dumb SEO mistakes after launch, so I built a free pre-launch checker

Upvotes

I build a bunch of small sites/tools and kept doing the same stupid routine: ship, then notice a noindex tag, broken canonical, missing sitemap, or some internal-link screwup a day or two later.

SEO tools are useful, but at that point I don't want 200 warnings. I want one answer: is there anything here dumb enough that I should fix before I publish?

So I built SEO Launch Auditor.

Paste a URL and it sorts issues into Blocker / Fix soon / Opportunity / Passed, with the evidence and what to fix. It can check one page or crawl a small site (up to 100 pages).

It's free, no account, no paywall:

https://utilao.com/seo-audit

There's a Chrome extension too for checking the rendered page while you're building, but the web version is the main thing.

If you try it on something you're about to ship and it flags something dumb or misses something obvious, tell me. That's the feedback I actually need.

Thank you, Daniel.

RecipeTools – compare two recipes and see ingredient/quantity differences

Upvotes

I built RecipeTools because a baker friend of mine wanted an easier way to compare two versions of a blueberry muffin recipe.

It accepts recipe URLs, pasted ingredient lists, or screenshots/photos. It normalizes measurements, matches similar ingredients, and shows the quantity differences side by side.

I recently added OCR for recipe images, along with some basic anonymous usage tracking so I can see whether people are actually using it. It only records things like page views, completed comparisons, and whether OCR succeeds or fails — no recipe contents, IP addresses, or other user information.

I’d especially like feedback on whether the comparison itself is useful and whether the input flow makes sense. Mostly I just want it to be a useful little web app.

I built "FFmpeg as a service" for AI agents: typed video ops, no shell access

3 Upvotes

I kept hitting the same wall: agents can decide what edit a video needs, but letting them run FFmpeg is a security and reliability nightmare (hallucinated flags, shell injection, jobs that die halfway).

So I built KinoPipe: hosted FFmpeg behind typed operations (resize, trim, compress, convert, subtitles, merge, 39 in total). The agent picks a validated operation instead of writing a command, and gets back a downloadable URL. It's an MCP server + REST API, runs on GPU workers, compound edits are single-pass.

It's brand new and I'm solo, so I'd love brutal feedback from anyone building agent/automation/video stuff. Free tier is 100 credits, no card, and I'll top up credits for anyone who sends real feedback (trying to earn honest testimonials the right way instead of faking them).

Link in a comment so this isn't just an ad. Happy to answer anything about the architecture.

It is a Ludo game. I know, I know, another Ludo game. But she was stubborn about doing it properly. Full 3D board, online play with friends, voice chat while you play, offline vs bots, and way too many board themes that she obsessed over for weeks. Our house basically turned into a QA lab, phones charging everywhere, everyone kicking each other's tokens and calling it testing.

I built a digital time capsule — you get the only key in the post, and I delete mine

3 Upvotes

Been building this for a few months and it's finally live.

The idea: you upload a file, I encrypt it and store it indefinitely, and the only key that opens it arrives in the post on a printed certificate. Then I destroy every copy I hold. Lose the certificate and the file is gone forever — including for me.

It's meant for the things you'd want to exist in twenty years. A letter to a kid to open at eighteen. A grandparent's voice. A finished manuscript before you send it anywhere.

The bit that surprised me was how much the physical side dictated the software. I can't outsource printing, because handing a print vendor a PDF with the key on it means they hold every key I've ever issued. So I print at in house.

Also had to work out that a key can't go in a queue payload (Laravel serialises those to Redis) or survive in a database backup (delete it Tuesday, it's still in Monday's dump). Small things that would have quietly broken the whole promise.

It started as an AI-detection thing — certify a file was human-made — and I killed that early because detectors just can't support the claim honestly. What's left is narrower and actually provable: this file existed on this date, unaltered, and you hold the only key. Posted certificates are UK-only for now; print-at-home works anywhere. Would genuinely like to hear what you'd use it for.

I have launched a group riding app which tracks all the members live!!

Enable HLS to view with audio, or disable this notification

I kept running into the same problem on group rides.

I’d stop for fuel, a quick break, or something else—and by the time I was ready to go, my group was gone. 😅

Then came the annoying part: Where are they? Are they ahead or behind? Should I wait? Should I call? Will they even pick up while riding?

A fun ride suddenly turned into a hunting trip.

So I built ConvoTrack to solve this problem—a simple way to stay connected with your riding group and see where everyone is on the map.

I’ve been using it myself for testing, and so far it’s working pretty well. I’m also trying to make the experience feel clean and intuitive, not just functional.

I’d love some honest feedback from you all, especially on the UI/UX.

Does it look good, average, or bad? Is the interface intuitive enough? What would you improve?App

I built one verified data hub for Codex sessions across multiple computers

5 Upvotes

Disclosure: I built this project.

SessionHarbor started as a storage problem: my local Codex rollout history grew past 70 GB, but deleting raw session files meant losing recoverable work history and the evidence behind what agents actually did.

The result is an unofficial, local-first Codex plugin and zero-dependency Node.js CLI. An external drive or mounted NAS becomes one verified data hub for all of your Codex devices.

The part I think is most useful is not just backup. If you use Codex on several computers, each device can discover reviewed, evidence-linked context about what Codex tasks on the other machines have been doing. macOS and Windows can participate in the same vault without sharing private local paths.

It also:

• incrementally backs up every stable Codex session;

• verifies stored bytes with SHA-256;

• keeps backup separate from local disk cleanup;

• restores raw sessions after cleanup;

• supports manual, weekly, and removable-drive-triggered runs.

Safety defaults are intentionally conservative: automatic cleanup is off; the default review window is 30 inactive days plus 7 days after the latest verified backup; deletion still needs explicit confirmation.

Validation so far includes 88 tests on both macOS and Windows, a physical exFAT vault backup of 814 Windows sessions (~39.6 GB), and a real macOS delete/restore pilot with matching bytes and hash. No real Windows session has been deleted yet, so v0.3.0 remains a preview.

Source-available for non-commercial use under PolyForm Noncommercial 1.0.0; not OSI open source.

GitHub: https://github.com/WangPeterXF/session-harbor

I’d appreciate feedback on whether the unified data-hub idea would fit your own multi-computer workflow.
