Full disclosure: I built this.

Every free disposable email checker leans on a static list of throwaway domains. The problem is that throwaway inboxes spin up new domains faster than any list keeps up, so the newest ones sail straight through.

IsItDisposable takes a different route. It inspects the live mail servers behind an address in real time, so it catches fresh throwaway disposable emails that lists have never seen. It returns a verdict in milliseconds, and you add it with one line of JavaScript on a form, or call a REST API from your backend.

One thing I was careful about: it flags privacy relays like Apple Hide My Email, but never blocks them, so real people are not shut out.

You can paste any address into the demo on the homepage and watch the verdict land. Would love feedback on the demo and the docs.

Intern Opportunity at FAANGPlus (The irony isn't lost on us 😄)

We built FAANGPlus to help people organize their job search, track applications, prepare for interviews, and ultimately land better opportunities.

So it's a little funny that today we're the ones posting a job opening.

We're looking for our first Software Engineering Operations & QA Intern to work directly with the founding team and help us improve the platform.

What you'll be doing

• Testing new features and reporting bugs
• Helping with operational workflows
• Reviewing and validating job-related data
• Providing product feedback and improvement suggestions
• Helping us make the experience better for job seekers

Internship Details

• Remote
• ₹10,000/month stipend
• Approximately 5 hours/day (flexible)
• 5 days/week
• Initial duration: 2 months
• Potential extension based on performance and company needs

We're intentionally keeping the schedule flexible because we don't want this internship to disrupt your studies, job search, or other commitments.

There may occasionally be situations where we need help on a weekend. This is not part of the normal schedule, and any additional contribution will be compensated separately.

Who we're looking for

We're not looking for someone with a perfect resume.

We're looking for someone who:

• Pays attention to details
• Likes finding and documenting problems
• Is curious about startups and technology
• Can communicate clearly
• Wants to learn how an early-stage startup operates

Students and fresh graduates are welcome to apply.

Why join?

You'll get an inside look at:

• Building a startup from the ground up
• Product development and testing
• Operations and growth
• The career-tech space and job market

You'll work directly with the founders and have a meaningful impact on the product rather than being assigned repetitive tasks.

How to apply

Send your resume and a short introduction to:

📧 faangplus@gmail.com

Include:

• Your current status (student, graduate, etc.)
• Why you're interested
• When you can start

Feel free to ask questions in the comments.

And if you're currently job hunting yourself, we'd love to hear what's been the most frustrating part of the process. Those conversations are exactly why we started building FAANGPlus in the first place. Kindly checkout www.faangplus.com .

Founder, full disclosure.

Listing sites give you the price. My tool gives you the verdict: paste a listing or pick a neighborhood, get BUY / WATCH / SKIP with the after-tax math behind it. Most verdicts come back SKIP — by design. Honest > flattering.

It covers neighborhoods worldwide — from Miami to Lisbon to Seoul. Basic verdict is free, deep report is paid.

Roast anything: the logic, the pricing, the homepage (it just failed my own 5-second test, so no feelings to hurt). If you invest remotely or out-of-state — what would make you trust or distrust this?

Answering every comment.

Most nutrition apps hand you a calorie target and leave you to it. Mr. Bite actually coaches you through it. Yeah i called him Mr Bite, don't judge lol.

Coaching

It's an AI nutrition coach you can talk to. Tell it what you're working towards, ask for a higher protein lunch, to analyse your eating habits or ask why the scale hasn't moved. It will give you answers and builds the change into your day, the way a coach would.

Tracking

Tracking is in there too, it's just not the whole show. Log your food by photo, barcode, voice or search in seconds, and see your calories and macros for the day on one screen. The coach reads what you log and adjusts your plan around it.

So you bring the goal. Mr. Bite plans the week, sorts the shopping list, and keeps you on track. Coaching first, admin second.

Got tired of losing my pets' vaccine dates and vet info across notes and paper, so I made FamilyPet+: vaccine/med reminders, vet records, weight and feeding logs, with real-time family sharing. Works for dogs, cats, rabbits, birds, reptiles, rodents, fish and horses — all on one account.

I'm the dev — feedback welcome, especially anything missing for your animals.

hey everyone, just shipped punchwatch to the app store and looking for early users.

it turns ur apple watch into a boxing coach. tracks punch type, form quality, and speed in real time. no phone needed at the gym, zero setup.

giving lifetime subscriptions to the first 50 ppl who download it. would genuinely love feedback on the detection accuracy and the session summaries.

Full disclosure up front: I'm the developer, this is my app, and it's free.

Like a lot of people here, I got tired of watching the same basket cost wildly different amounts depending on the store and the week. So I built PriceWise — you add the items you actually buy, and it compares flyer prices across stores in Toronto/the GTA to tell you where your whole list costs the least, then routes you there. It also tracks how much you've saved over time.

Not trying to sell anyone anything — it's free, and I'd rather it actually be useful to this crowd than not. Link: https://apps.apple.com/ca/app/pricewise-grocery/id6770648419

Honest caveats: it's iOS-only right now, it's new so store coverage is still growing, and I'm actively adding stores. Tell me which ones you want and what you'd want it to do — I'm reading every comment.

Been thinking about the earliest stage problem for a while: you've launched something but have zero traffic and zero budget to get it.

Ads are expensive. Cold outreach feels gross. SEO takes months.

So I built something stupid simple a bar that sits at the top of your site showing another founder's startup. In return, your startup gets shown on theirs.

One line of code. No cost. No algorithm. Just founders helping founders get their first eyeballs.

Called it StartupBar. It's completely free, probably always will be.

Would love feedback from this community does this actually solve a real problem or is it a solution looking for one? Also curious if anyone here has tried similar traffic exchange approaches and what worked / didn't.

Since user feedback is a bottleneck of many startups, I'm here to help out. I'm an app designer of 5 years and a fellow startup founder. I'll test and review the first 10 apps posted in the comments.

If you want to return the favor, you can review my app WordPolish, an AI writing polisher for Mac.

Edit: woah, that's lots of action. I'll review some apps over the weekend, but most on Monday.

I’m a student builder. Every hackathon and side project I joined started the same way: new WhatsApp group, links and files buried in chat by day two, someone two people update the Google sheet, everyone else ignores it. The truth I came across is: lack of coordination kills more projects than bad ideas.

I’ve been living in this problem space for a while. Meta’s Whatsapp API is strict. Onboarding means signup, create workspace, invite teammates, each person links their own phone. That’s a lot of friction for a team that might exist for one weekend. We did not need Notion or a full PM stack for this!

So, I built Euclis- a real-time small team management cum productivity platform, that adapts to you- whether you’re typing a quick update on WhatsApp, using the web or letting claude handle the heavy lifting.

• Chat, and it’s done: Text the WhatsApp bot like you’re talking to a teammate - "add task: finalize the pitch deck, due tomorrow" - and the board updates for everyone. No formalities. No friction.

• Claude syncs it all: Work in Claude? Manage your board while you’re chatting with Claude: no tab switching required.

• Everything in one place: Assets, links, notes-all tagged and organized in a single workspace. No more digging through messages or lost files.

• Visual clarity: The built-in whiteboard lets you map out ideas, flowcharts, or wireframes so everyone’s on the same page-literally. My personal favourite:)

Try it now at euclis. What is you opinion? Any features you’d love to see, or pain points I missed would be appreciated!

Hi everyone, final year CS student here. (finally)

I spent ages wanting to build things but I either had an idea and no designer, or wanted to join a project and no way to find one that needed me.

I mainly focus on Game Development, but I am really bad at Pixel Art and finding a teammate to help with pixel art while I code the game has been a huge struggle which has slowed down the game's progress by a lot.

And so, I made Buildr. You swipe to find people based on skills and what you're building, match, then chat in the app. Kind of like a dating app but for finding people to build with instead.
You can also swipe on other people's projects so that you can work with them on THEIR project instead. Win win situation :)

It finally got accepted on the App Store and I would love if anyone wants to try it and tell me what's broken or has any suggestions. Buildr: Cofounder & Team Match App

P.S: Thanks to every single one in advance, I appreciate you.

Logseq stores everything as plain .md files, but if you ever open one of those files directly on iOS (from Files, iCloud, Dropbox, a backup, etc.) you just get raw text. I built a small viewer to read them rendered on a phone.

Md Preview:

• Renders GitHub-Flavored Markdown — headings, tables, task lists, footnotes

• Code blocks with syntax highlighting, plus LaTeX math and Mermaid diagrams

• Opens .md / .markdown / .mdx / .rmd / .qmd from Files or the Share Sheet

• 100% on-device — no account, no uploads, no ads, no subscriptions

Free on the App Store: https://apps.apple.com/app/id6760341080

Details: https://markdown.cybergame.ai/

Not a Logseq replacement at all — just a quick way to read loose .md files when you're away from the desktop app. Curious how you all read your graph on the go.

Solo-built. Paste your URL, get a preview free, no signup. Just rebuilt the whole render pipeline and want real sites stress-testing it, especially weird ones (heavy JS, no logo, sparse copy). Tell me where the output falls short → rendrio.io
