One thing that seems difficult when building a SaaS product is deciding where to stop developing things yourself. Some features make sense to build internally because they're central to the product. Others might be useful to customers but require a lot of infrastructure and ongoing maintenance.

Payroll is a good example. It might fit naturally into a platform that already handles employee management but building everything behind it is a completely different commitment.

For founders who've faced this decision, what made you choose an existing provider over building the feature yourself? Was it development time, ongoing costs or something you hadn't considered initially?

im a musician and write songs in the most random moments. i always end up switching between voice memos, files app for the instrumental and my notes. Even when in front of ableton, setting up a project takes way too long and by then the idea is often gone.

so i built Demos, a little iphone app for recording song ideas. load a beat, loop a section, record takes, punch in, add a bit of comp/eq/reverb/delay and export wavs, mp3s or stems.

i know there are already tools like this out there, this isnt meant to compete with anything, it just started as a personal tool and figured some of u might find it useful too. first public build, so expect bugs :)

free on testflight, no account, no tracking.

would love feedback on what feels weird, what breaks or what u wish it could do. lmk what u think!

I built LazySiren solo: a full operating system that runs in your browser — desktop, windows, files, a real Debian terminal — and its AI, Siren, operates the whole thing. She can use every app, manage your files, and forge new apps on demand that appear right on your desktop.

Try it in 2 minutes (no install): open https://lazysiren.com/landing , boot the OS, and ask Siren to build you any small app you can think of — a tracker, a planner, a tiny game. Then tell her what to change; she edits it on the spot.

It's free during the beta, works on Android too (same account), no API key needed.

What I want feedback on: does the concept click in the first 2 minutes? What was confusing? What did you ask her to build?

Roasting welcome — I'd rather hear it now. Thanks!

Hi! I'm building Re:Save, an Android expense tracker where you put money into categories and choose which category to spend from. It's a small app with one main overview, and I'm looking for people to help me figure out whether it feels clear in everyday use.

The closed test is live on Google Play. I'd love around 20 volunteers who can stay enrolled for 14 days, try a few things during that time, and tell me what feels awkward or doesn't work.

The main tracking features work offline. You don't need to connect a bank or sign in with Google, and you're welcome to use made-up numbers. Android 8.0 or newer is needed.

A few things I'd like fresh eyes on:

- Can you create categories and set money aside without instructions?

- Is it clear where an expense comes from?

- Do transfers and the transaction history make sense?

If that sounds like something you'd try, comment here and privately send me the Google account email you use for Google Play. The test currently uses an email list, so I'll add you first and confirm when you can join. Please keep your email out of public comments.

Test opt-in (after you're added):

No need for a polished review. A quick 'this button confused me' or a bug report would be really useful. Thanks for taking a look!

I'm Brian, developing War-Dogs with TWB Games. I'm looking for unpaid first-time testers who can try a short session and explain where the experience becomes unclear.

The game has automatic squad attacks, aimed special abilities, and permanent upgrades between attempts. The free demo contains two maps and fourteen stages; I'm only asking for initial impressions, not a full completion.

Download page with separate Windows and Android options:

https://the-world-beneath.itch.io/war-dogs

The most useful feedback would be:

1. Was choosing the correct download and getting started clear?

2. Did you understand what survives a failed deployment?

3. Were recruiting, buying upgrades and using specials understandable?

4. Did anything break when saving, closing and returning?

Please reply here with your platform and build number. A few sentences about the first point of confusion would help.

AI disclosure: Generative AI is used extensively across code, graphics, writing and audio. I handle creative direction, design decisions, editing and hands-on testing. AI assisted with drafting this request.

we are running our second closed test group right now and trying to stop managing onboarding emails and bug logs across spreadsheets and webhooks. our lead mentor gave us an intake link for the partner discount, but looking into hubspot for startups pricing, the contact tier limits make me nervous.

right now we only have around 35 ppl in the app and maybe 150 on an early waitlist. paying extra every month just to hold email records for free beta testers who might never convert feels like burning runway before we even launch paid plans. trying to see how other founders handled early user lists without triggering plan bumps while still fixing bugs.

Hi everyone, I'm the solo developer of Weorclip, a free video downloader and editing app for Windows 10/11. It is in beta, and I'm looking for people willing to try one small editing task and tell me where they get stuck.

You can trim a video, generate subtitles, remove silences and reframe it for vertical clips. Editing and exporting run on your own computer. There is no account requirement or watermark, and an English interface is available.

What I'd especially like feedback on:

- Does setup complete successfully?

- Can you import your own clip, add subtitles and export it?

- Which step is confusing, slow or buggy?

Website, feature overview and download: https://weorclip.com/en/

I'm the developer, so this is a request for honest beta feedback. No positive review or purchase is requested. If you prefer to look through the site before installing an unfamiliar Windows app, that's completely understandable. Questions and critical feedback are welcome here.

Hey everyone! I'm the founder of Agenlate (https://agenlate.com/). For the last 8 weeks we've been building it, and it's now in BETA.

The idea: instead of one chatbot, you set up a small team of AI agents in plain words (a researcher, a writer, a checker) and a supervisor coordinates them toward one goal. No code.

What it does today: the agents search the web, read pages and write the result, and you see every step and what each run costs. The video shows an example where a researcher and a writer turn quick research into a launch announcement for a coffee shop.

For now, in the beta, you bring your own OpenRouter API key, so you can use any of the language models listed in the platform.

Today it's research and writing, but the goal is for these same teams to coordinate on more complex tasks.

What I'd love: try it on a real task of your own (a topic to research, a draft to check) and tell me what worked, what confused you and what you'd want it to do next.

It's invite-only for now. Comment or DM me and I'll send you a beta code. If you have questions before you start, or while you're using it, ask me and I'll gladly guide you.

What it does: Each morning Echo picks one photo from your own library, usually from months or years ago. You keep it or swipe for another, and you can add a line or a short voice note. Kept photos build a private Wall, a map of places, a page-turning book and a short film of your year.

Who I'm looking for: - Anyone with thousands of photos they never look at - People who use iPhone in a language other than English. It's in 38 languages, and I especially want feedback on Arabic, Hebrew, Hindi, Japanese, Korean and Turkish. - People with lots of screenshots, memes or AI images in their library. Echo should skip all of those, and I want to know if any slip through.

What I'd love feedback on: 1. Did the first photo it showed you feel worth seeing? 2. Was anything in onboarding confusing or slow? 3. Did the free limit (4 memories a day) feel fair? 4. In your language, does anything read like a machine translation?

Privacy: There's no account, and your photos are never uploaded to us. They stay on your device and your own iCloud.

It's free on the App Store: https://apps.apple.com/app/id6775021634

Personal trainers often end up managing clients across WhatsApp, spreadsheets, notes, and separate tools for payments and scheduling.

I wanted to build something that brings those workflows together.

So I built Traneos, a platform for independent fitness trainers and small coaching teams.

It includes:

• Client management and progress tracking
• Workout scheduling and attendance
• Client follow-ups and reminders
• Payment tracking and invoicing
• A client portal and mobile app
• Tools to manage leads and coaching teams

The goal is to help trainers spend less time managing scattered information and more time coaching their clients.

I'm sharing it here because I'd love honest feedback from people who build products or work in fitness.

If you're a personal trainer, online coach, or someone familiar with the fitness industry, I'd particularly appreciate your thoughts on what would make a tool like this genuinely useful in your day-to-day work.

I'm the person behind the product, so I'm happy to answer questions and explain the decisions behind it.

I like rating anime episodes on IMDb as they come out, and I couldn't find anything that does that for manga, so I made it. It's called MangaRate. You rate individual chapters, add series to a read list, and each series gets a graph so you can see which chapters were the high points.

It's just me working on it and it's brand new, so I need people who actually read manga to use it and tell me what's broken or confusing. If you follow a long series like One Piece, that's a good one to try since there are a lot of chapters to graph.

If you have five minutes: open a series you've read, rate a few chapters, then look at the graph. I'd like to know if rating feels quick, if anything confused you, and what would make you want to keep using it.

There's a report issue button on the manga pages if something looks off.

Tasket++ lets you define your own clicks, keystrokes, cursor positions and system operations, then replay them exactly when you want. It’s a simple Windows tool that handles repetitive workflows for you: auto‑send messages, paste text anywhere, take silent screenshots, launch or close apps, adjust volume or run your end‑of‑day shutdown sequence.

Everything runs locally, with no telemetry, no cloud, and no complexity.

What it can do:
- Replay user‑defined cursor positions and keystrokes
- Paste predefined text anywhere
- Perform system actions: open files/programs, change volume, take silent screenshots, shut down, files/folders operations
- Schedule tasks at a specific time, at startup, or run via desktop shortcut
- Run tasks once, in loops, or indefinitely
- Discreet mode: runs quietly from the tray
- Use command line to autorun a task : Tasket++.exe "TaskName" <delayInSeconds (>0)> <NumberOfLoop (-1 for infinite)>
- Easily share tasks between different PC : export/import task files and program data, use feature to rescale cursor positions

Local, portable, free, open source. Privacy intact.

Nothing is vibe coded, I never used AI (except for the choice of UI colors suggested by Copilot).
Conception is genuine, I didn't know about similar tools when I began developing it.

I'm looking for testers or quick feedback (beyond its visual aspect), please give a try and comment here :)

Fluo is an AI language tutor built to help learners achieve real-world functional fluency and conversation confidence. Key highlights of the platform include:

• Goal-Driven Curricula: Tailored lessons designed around specific real-life situations, such as travel or studying abroad.

• Interactive Role-Plays: Real-time voice and text scenarios with native-sounding characters to practice immersive conversations in low-stakes environments.

We're looking for 20–30 beta testers to try Fluo and share honest feedback on the user experience, voice practice latency, and overall functionality. As a thank you for helping us refine the platform, all beta testers get a free month of Pro access (or 2 weeks free for students who verify with a school email). If you'd like to help shape Fluo, give it a try and let us know what you think!

I need some android users to test an app. Scheduling app but it also does money requests and has the time capsule for shared pictures. If you could help, please reply with your email or message me thank you.

Here's the exact flow I built, step by step.

1. Upload the contract. PDF, Word, plain text, or paste it in.
2. ALYRO analyses it and flags clauses that carry risk, tied to the specific clause so you can find it fast.
3. Review the flags. You decide which ones matter for your situation.
4. Generate a counter-negotiation draft addressing those clauses.
5. Send it back to the client before you sign.

There's also a comparison feature. Upload the client's version next to your own template and see where they differ.

What it won't do: replace a lawyer on a six-figure deal. It's for the everyday freelance and consulting contracts where hiring one isn't realistic.

It's still early. 101 visits in the last 30 days, and I'm after feedback from people who actually sign these things.

If you try it, tell me where it felt slow or unclear. What would make you trust the flagged clauses enough to act on them?

Hi, I'm bulding Header - a native Mac app for notes, meeting minutes and research that works directly on a folder of plain Markdown files. There's no database and no sign-up. If you delete Header tomorrow, your notes are still ordinary .md files.

Who I'm looking for

• You already keep notes in Markdown: an Obsidian vault, a Dropbox or iCloud folder, anything. Header opens it as it is and doesn't rewrite your files.
• You take meeting notes and would record one short call. Transcription runs on your Mac.
• You write with sources (papers, DOIs, PDFs) and want citations in your notes.

What I'd love to hear

1. Did your existing folder open and index cleanly? Roughly how many notes, and how long did it take?
2. Did anything render wrong: tables, math, Mermaid, links, frontmatter?
3. Where did you get lost in the first 10 minutes?
4. What made you close it?

The details

• macOS 14.4 or later, Apple silicon and Intel. Notarized download or TestFlight.
• Free during the beta.
• AI is optional and off by default. Bring your own key, use Ollama, or Apple Intelligence on supported Macs.
• It's a beta, so please try it on a copy of your notes first.

You can report problems from Help > Report Issue in the app, or just reply here. I'll answer every comment, and if you drop your own project below I'm happy to test it back.

I'm building Publishub to help content creators improve their workflow.

I'm looking for a few creators willing to try it and share honest feedback.

Would anyone be interested?

Hi everyone!

I'd like to introduce TCG Market, a project that brings collectible cards and perpetual trading together.

The project explores a different way to engage with the trading card market, combining the world of collectibles with perpetual trading mechanisms.

I'm looking to connect with trading card enthusiasts, TCG collectors and traders who are curious about this concept. I'm also interested in hearing honest feedback from people who understand the collectible card market.

A few things I'd love to hear your thoughts on:

• The idea of combining collectible cards with perpetual markets
• What would make this concept interesting to collectors and traders
• Features you'd like to see in a platform like this

🚧 Currently in Demo

Website: https://tcgmarket.trade
Discord: https://discord.com/invite/gmkgwjfhKQ

I'm the person behind the project and would love to hear your feedback and answer any questions.

Thanks for checking it out!

Hey everyone. I'm a solo dev and I've just spun up the beta for a web app I built called Who's On?

The Problem: Social media is just not social at all.

The Solution: I built an app that only unlocks from 7 PM to 11 PM UK time. No downloads required—it's a pure web app. You just click the link and you're in. The idea is that everyone logs on at the same time so there are no empty rooms.

What I need from you tonight: The servers are live right now. I need a few people to jump in, click around, create a room, and tell me if the UI breaks or if the audio cuts out.

I'm not selling anything, there are no ads, and I'm not collecting your data. I'm just one guy who needs real humans to test this before I show it to a wider audience. You can join any time and maybe set up your own room to chat with mates.

Link: https://chat-whoson.preview.emergentagent.com/?utm_source=share

I'll be sitting in a room called "Procrastination Station" from 7 PM. If you're around, please hop in for 5 minutes and just say hi. Let me know whats shite so I can fix it!

Thanks.

Hi, I'm Jon from Analyzera, a small fintech in Sweden. We've just opened a beta of our MCP and are looking for people to try it. Our goal here is to expose the tools that otherwise are out of reach or too expensive for most investors, with the aim to make you able to accomplish more.

If you haven't used an MCP before: it's a connector for ChatGPT or Claude. Once it's connected you can ask the AI about investing, and it answers using real market data, risk models and processes instead of guessing.

Link: www.analyzera.com/mcp

Its for anyone who invests a lot, a bit or is just curious, you don't have to be technical at all. Things you could try: take a screenshot of your account and import your holdings, then check your risk or how much your funds overlap. Or screen some stocks, build a strategy in a theme, or with fundamentals and backtest it. See how that impacts your current investment. See how a monthly deposit in a fund robot you just created yourself could turn into in 20 years. whatever you feel like really.

It's not financial advice, it won't tell you what to buy, it just gives you the numbers.

Connecting takes a minute or two, there's a guide on www.analyzera.com/mcp. Free during the beta and we’re open to extending that after the beta for anyone who has tested it.

On data: we only get what the AI sends us (like a search, or holdings you give it), never your chats. Anything you save is stored in the EU (Stockholm), and you can delete it, or your whole account, whenever you want. It also can't move money or trade. And heads up, the chat itself goes through ChatGPT/Claude under their terms, not ours. More details on the site.

It's a beta so stuff will probably break here and there, that's kind of the point. Any feedback is great, good or bad. Easiest is if you tell the AI to send it to us, comment here or DM me directly.

Thanks! :)

Could a few people help me improve my app? (iOS TestFlight)

Hey everyone!

I’ve been working on a small project called LEVELUP, an app for building habits, keeping track of daily tasks, and working towards personal goals.

I’ve reached the point where I’d really appreciate some outside perspective. I know I’m a bit too close to the project now, so it would be helpful to hear from people who are trying it for the first time.

If you have a little time, I’d love for you to give it a try and tell me honestly:

• What feels intuitive, and what feels confusing?
• Which features are actually useful to you?
• What feels unnecessary or is missing?
• Did anything break or behave unexpectedly?

There’s also an AI coach in the app that I’m particularly interested in getting feedback on.

This is an early version, and I’m not expecting anyone to sugarcoat anything. Critical feedback is just as valuable as positive feedback — probably more so!

If you’re interested in trying it on iPhone, here’s the TestFlight link:
https://testflight.apple.com/join/fYTsQWHf

Thanks for taking the time to read this. Even a few honest thoughts would help me a lot.
