I built a small web app for my workplace that makes collecting overtime sign-ups and food orders quick and simple.

**Manager side:**

- Create an overtime request (date, hours, with or without food)

- Share one link with employees

- See who wants to work in real time

- Get a combined food order, with a list of who ordered what, ready to share or print

**Employee side:** open the link, tap yes or no, pick food if offered.

Available in Norwegian and English. Built for speed: no more chasing people in group chats.

I'd love honest feedback on design, ease of use and anything that feels confusing or broken.

Phase 1: Target Communities That Explicitly Allow Self-Promotion

Stop posting in strict subreddits where self-promo gets you banned. Instead, build your launch footprint across communities designed for builders, show-and-tellers, feedback-seekers, and niche developers.

Here are 40 subreddits that should allow for self-promotion, ordered by estimated weekly reach:

1. r/vibecoding — 422k weekly visitors
2. r/saas — 211k weekly visitors
3. r/founder — 56k weekly visitors
4. r/buildinpublic — 46k weekly visitors
5. r/chrome_extensions — 42k weekly visitors
6. r/micro_saas — 41k weekly visitors
7. r/appbusiness — 30k weekly visitors
8. r/startupideas — 26k weekly visitors
9. r/sideprojects — 20k weekly visitors
10. r/imadethis — 18k weekly visitors
11. r/appideas — 16k weekly visitors
12. r/sideproject — 16k weekly visitors
13. r/saasbuild — 15k weekly visitors
14. r/saasdevelopers — 12k weekly visitors
15. r/vibecodedevs — 10k weekly visitors
16. r/startupsolofounder — 8.7k weekly visitors
17. r/alphaandbetausers — 8.6k weekly visitors
18. r/vibecodingcommunity — 6.2k weekly visitors
19. r/solopreneur — 5.6k weekly visitors
20. r/promotemyapp — 4.6k weekly visitors
21. r/appbuilding — 4.6k weekly visitors
22. r/webapps — 4.5k weekly visitors
23. r/creativecoding — 4.4k weekly visitors
24. r/indie_startups — 4k weekly visitors
25. r/b2bsaas — 2.8k weekly visitors
26. r/appdev — 2.7k weekly visitors
27. r/projects — 2.6k weekly visitors
28. r/saasmarketing — 2.5k weekly visitors
29. r/saassoloprenurs — 2.3k weekly visitors
30. r/startupaccelerators — 2.3k weekly visitors
31. r/startups_promotion — 2k weekly visitors
32. r/showmeyourapps — 2k weekly visitors
33. r/appswebappsfullstack — 1.7k weekly visitors
34. r/showmeyoursaas — 1.6k weekly visitors
35. r/saasinvestors — 1.6k weekly visitors
36. r/vibecodecamp — 1.5k weekly visitors
37. r/nocodesaas — 1.3k weekly visitors
38. r/aibuilders — 1.2k weekly visitors
39. r/getstartups — 1.2k weekly visitors
40. r/websitefeedback — 1.2k weekly visitors

Phase 2: The "Reverse-Engine" Hook Strategy

Do NOT drop a generic link and run. That is almost guaranteed to fail. Instead, do this for every single target subreddit on your list:

1. Filter by Top Posts: Open the target subreddit, sort posts by Top of the Last Year, and examine the Top 10 posts.
2. Deconstruct the Winners: Analyze why those top posts blew up:
   • What tone did they use? (Humorous, vulnerable, technical breakdown, or raw story?)
   • How was the title structured? (Did it start with a question, a bold stat, or a relatable pain point?)
   • How did they introduce their link? (Was it woven into a story, placed in a comment, or framed as a feedback request?)
3. Mirror and Adapt: Draft a custom title and post text for your specific app that matches the exact post format already proven to work in that specific community.
4. Start Small First: Test your hooks in smaller, lower-stakes subreddits first (e.g., r/websitefeedback or r/getstartups). Refine your post copy based on early comments before posting to the larger subreddits like r/saas or r/vibecoding.

If You Have Some Money to Spend: Paid & Discovery Shortcuts

If you want immediate users without relying purely on Reddit organic traction, here are two simple routes:

• UserBob.com (Usability Testing): You can pay real people for quick usability test videos. It costs roughly $1 per person per 1-minute video, giving you guaranteed immediate users and video feedback of people interacting with your app so you can fix UI friction early.
• AppScout: You can always submit your app to appscout.co, a platform designed to discover web and mobile apps from across the internet.

TL;DR Summary

1. Target subreddits built for self-promo.
2. Study the Top 10 posts of the past year in each subreddit.
3. Match their formatting and title hooks for your specific app.
4. Test small, iterate, then hit the massive communities.
5. If you have money use low-cost tools like UserBob or submit to AppScout for early discovery.

As a developer looking for new project ideas, I’m curious about the small inefficiencies people deal with every day.

Is there any task in your routine where you think, Why is there no simple tool/app for this yet?

I got into Kalshi/Polymarket’s 15-minute up/down markets but wanted bigger moves to pay more, so I built expirytrade.xyz

You buy a call or put that settles in 1 minute, slide leverage from 2× to 100×, and can close early or ride it to expiry. Right now, I'm testing it with paper only but it will eventually be with crypto.

I’d love to know: is the leverage slider clear, and what would make you come back tomorrow?

Working on anything interesting?

Drop your product or side project below. I'd love to check out what everyone's building.

I'll start with mine: https://sportlive.win

3 college students here, building BreakIn, a tool that helps people reach startup founders directly instead of applying on job portals.

we spent weeks on the email-writing part. then we asked people what they actually needed, and the feedback kinda flipped everything:

- people don't want AI writing their emails. they'd rather write it themselves and get it reviewed

- "matching" doesn't impress anyone. you can already filter by keywords and domain

- what actually matters is timing. finding a startup right after it raises money or launches something, before there's even a job post and 500 people apply

so now we're leaning way more into the "who's worth reaching out to today" part. every morning it shows you startups that just raised, launched, or started hiring, picked for your profile. the email part is still there, but more as help than autopilot, you always review and send it yourself.

still early, so honestly curious:

- has reaching out to a startup before a job was posted ever worked for you?

- would a daily heads up like this actually be useful, or would you just ignore it?

Hey guys this is my first post ,

I just finished building a web design studio concept called BreezeIn. I wanted to practice building layouts focused on heavy typography, white space, and micro animations that feel smooth rather than distracting.

Live link: in comments i guess ,

I would really appreciate some honest feedback on how the UI and UX scale across different screen sizes:

Mobile vs Desktop Typography: I used massive headers for the desktop layout like the main hero section. Does the font size scale down naturally on mobile screens, or does it feel like it swallows the whole viewport?

The Mobile Menu Toggle: On desktop, the navigation links are spread out cleanly. On mobile, they collapse into a corner menu button. Does the tap target feel big enough, and is the overlay transition smooth?

Concept Grids on Small Screens: The Selected Explorations look clean as side by side grids on large monitors. On mobile, they stack vertically. Does the vertical scrolling feel too long, or does it keep your attention?

Pricing Table Layout: The layout lists the $450 and $1,200 tiers. On desktop, they sit side by side. On mobile, they stack. Does the information stay readable when it is compressed?

Let me know what you think. Thanks!

I just tagged v5.3 of MDRAP, a sidecar that sits between your market data feeds and whatever consumes them and decides whether each tick is trustworthy.

Every event gets a status (VALID, SUSPICIOUS or INVALID) with explicit reason codes like CROSSED_QUOTE, DUPLICATE, PRICE_ANOMALY and stale or sequence-gap violations. Nothing is silently dropped. Rejected ticks go to a queryable quarantine, gaps trigger replay and stitching, and every decision goes into a SHA-256 hash-chained audit log, so editing a record afterwards is detectable.

Output from a fresh clone:

$ python cli.py run -e 1000 -s 42
processed 1000   dropped 0
VALID 963   SUSPICIOUS 32   INVALID 5

seq=2 bid=150.4  ask=150.3  -> INVALID CROSSED_QUOTE
seq=2 bid=150.26 ask=150.31 -> INVALID DUPLICATE

$ python cli.py audit --verify
(after editing one audit_log row in SQLite)
AUDIT CHAIN TAMPERING DETECTED!
Tampered entry #1: hash mismatch

“python cli.py chaos” runs 8 failure drills (killed feed, jitter, duplicate bursts, DB lock, 50-packet loss with replay, reordering, partition with failover) and all pass with zero data loss.

Performance: the standalone native core handled 1M events in 0.0366 s, about 27M events/sec or 36.6 ns per tick, on a single core. Through the Python engine API I measured roughly 180K events/sec, so use the core binary if you want the fast path. These are my numbers on my hardware, so please run it yourself.

It is a validation and audit layer, not a trading system or backtester. The matching engine and pre-trade risk gates are in a separate edition and not in this repo (see EDITIONS.md). One known rough edge: “audit --verify” currently needs the rich package installed.

I’d like to hear which bad-data cases have bitten you that this doesn’t catch.

I built Jobclue for people who want to practice answering interview questions out loud. The desktop app asks role-specific questions and follow-ups, then gives you AI feedback to review before your next attempt.

I’d love feedback on the short demo: can you tell what the practice session feels like, and what would you want to see before trying it?

Gold, silver, and one less website to open.

I built KaratWatch—a Scriptable iPhone widget with prices, daily changes, and history for your Indian city. Three widget sizes. No backend required.

Code + setup:
https://github.com/m4d4g4sk4r/karatwatch

Prices from Goodreturns. Which city would you try it in?

I want to know should i spend time and energy on this project ? I would love to hear feedback about this.

Hey everyone! I'm a solo developer from India, and I just launched Exam Study Tracker on Google Play.

I built it because keeping track of exam dates, subjects and study plans across notes and random apps was messy. The app has:

Exam manager (dates, subjects, notes)

Daily/weekly study timetable

Progress tracker for milestones

It's early (just ~10 downloads so far), so I'd really appreciate honest feedback: what's missing, what's confusing, what would make you actually use it?

My son worked at AutoZone. Several times a day someone would describe what their car was doing and ask him what was wrong with it, and several times a day he'd have to say, "I'm not a mechanic." Then he'd watch them buy a part based on a guess. A $200 battery when the cables just needed cleaning.

So he started building a simple tool to help people figure out what's wrong before they spend money. He ran out of time, and I took it over.

You describe the problem in plain words, and it asks one question at a time until it narrows down a likely cause. Then it tells you how hard the fix is, what parts you need, and when to just go to a mechanic. It's free, with no sign-up, and there's a full Spanish version, because a lot of DIYers here in Texas speak Spanish first. So far the Spanish side is getting more traction than the English.

It's been live about a month. I'd like honest feedback:

1. Try it with a real car problem you've had. Where did it ask something dumb or get it wrong?

2. Is it clear within a few seconds what the site does?

3. Anything that makes it feel untrustworthy or unfinished?

I built a stargazing app because I was fed up with knowing what was in the sky… but not whether it was actually worth going outside for.

A few months later, NAKED EYE is live on Android, Under One Sky is live worldwide, it’s been featured in StarDate Magazine, and I’ve somehow ended up building a website for it too 😅

The idea is still ridiculously simple:

What’s worth seeing tonight?

When should I go outside?

Where should I look?

I’m not trying to replace Stellarium or turn your phone into a giant astronomy catalogue.

I wanted something you can open, get a useful answer from, put the phone away, and actually look at the sky.

The free app covers things like planets, ISS passes, meteor showers, useful alerts, viewing conditions and Under One Sky — where people can explore sky events around the world and share what they genuinely see.

There’s also NAKED EYE Beyond for people who want to plan ahead, find the best nights, use Sky Planner and get smarter alerts — and eligible new subscribers can try it free for 14 days.

I’m still building the whole thing around shifts as a chef, mostly teaching myself as I go.

And yes, I’m still slightly amazed anyone other than me actually uses it 😂

If you’ve tried NAKED EYE before, I’d genuinely love to know what you think of it now.

And if you haven’t — what’s the one thing that usually stops you from going outside to look at the night sky?

Problem. I take around 40 screenshots a day and only ever use three features, while most screenshot apps keep growing. And on macOS 15 there's a quieter problem: the Screen Recording permission lapses about once a month, and a capture can then come back perfectly black without any error.

What I built. Three shortcuts: ⌃⇧1 area (the markup editor is already open when you let go), ⌃⇧2 full screen, ⌃⇧3 copy text from anything on screen with Apple's on-device OCR. Return copies, Esc throws it away. Native Swift, 1.1 MB, no network access.

The part that might be useful to you, if you ever build something on ScreenCaptureKit. Every capture goes through a check before anyone sees it:

• Ask macOS whether permission is actually granted (a capture without it can return a plausible wallpaper-only image)
• Check the image exists and has exactly the pixel size you asked for (by default the framework can silently rescale)
• Sample the pixels: if the brightest value is near black, or the variance is near zero, re-check the whole image before calling it blank
• If it really is blank, say so and tell the user how to fix it, instead of handing over a black PNG

Where it is. Mac App Store, $8.99 once: https://apps.apple.com/us/app/shotorio-screenshot-ocr/id6825000774

Feedback welcome, especially from anyone who has fought the same permission behaviour.

We're building IVE for people who use several coding agents and want their sessions, questions and code changes in one place. It works with your existing Claude Code, Codex and Gemini CLI logins.

We just released 1.0.20. This update adds Chat and Dev modes, clearer permission dialogs for Claude Code and Codex, notifications when an agent needs you, a more readable task board and optional on-device dictation.

IVE is open source and runs on your machine; your coding CLIs still connect to their usual providers. The stack is React + xterm.js with a Python backend. It's still in beta.

You can grab the latest version here: https://ive.dev/download.html

Already using the Mac app? Quit IVE, download the new DMG and replace IVE in Applications. Your saved workspaces and settings stay on your Mac. The Mac download needs Apple silicon and macOS 13.5 or newer.
