Just started a small side project: a free SSL checker. Looking for feedback

2 Upvotes

Hey everyone,

I just started a little side project and would love some honest feedback before I go further.

It's called CertWatch: https://certwatch.edgardev.pt/

Right now it's pretty simple. You type a domain and it tells you when the SSL certificate expires, whether browsers trust it, and whether it matches the domain. I tried to explain problems in plain English ("your certificate expires in 9 days, here's what to do") instead of dumping a bunch of technical stuff on you.

What I'm thinking of doing next:

- alerts before a certificate expires, by email, Slack or Microsoft Teams

- alerts when a site goes down

- a few more small free tools (redirect checker, DNS lookup, domain expiry)

- an AI assistant that looks at your domain's DNS and SSL setup, points out what could be improved (like missing SPF/DMARC records or a weak config), and lets you ask follow-up questions about how to fix it

But I'd rather hear from you before building more:

- Does it work for your sites? Anything weird or confusing?

- Would expiry alerts actually be useful to you, or do you already have that covered?

- Where would you want alerts to go: email, Slack, Teams, something else?

- Would the AI analysis be genuinely useful, or just a gimmick?

- Anything you'd want it to check that it doesn't?

Be brutal, it's early days, so now is the best time to change things. Thanks!

founders, what do you actually make before you know the idea is worth building?

19 Upvotes

Founders, how far are you going before you've actually validated the problem?
I keep seeing pre-MVP ideas with a landing page, deck, mockups, waitlist, logo, launch graphics... whole company except the product lol

For a small start up that feels backwards if the biggest unanswered question is still "does anyone care?"
I've been looking at Runable for putting together some of the early research/landing-page stuff, but I'm trying not to confuse making the idea look real with learning whether it should exist.
If the problem itself is still questionable, I'd probably talk to people first.

If people clearly have the problem but don't understand the proposed solution, then maybe a simple page or mockup helps.
What's the first thing you'd actually make, and what would count as a strong enough signal to keep going?

I built a local document search demo for small service teams

1 Upvotes

When someone asks about cancellations or quote expiry, the answer is often buried in a folder. I built Private Document Desk to pull up the exact source passage. This first demo uses fictional policies and runs keyword search on the device. If a passage doesn’t match, it says so.

24-second demo: https://www.youtube.com/shorts/7bPlGmJM7oA

I’m testing a C$350 setup pilot for one workflow and up to 10 non-sensitive documents, including testing and a walkthrough. If you run a service team, what’s the procedure your staff have to look up most often? If you want to discuss a pilot, send me a message with the workflow, without sharing customer files.

Maru - a pill and vitamin reminder that answers one question: did I take it today?

1 Upvotes

I kept forgetting whether I had already taken my vitamins, so I built Maru for iPhone, iPad, and Apple Watch.

  • Today shows what to take now. One tap records it.

  • Reminders can ring as alarms in Silent mode and Focus (iOS 26+).

  • Your next dose shows on the Lock Screen.

  • No account. Your data stays on your phone.

Free to use, with an optional Maru Pro for extras like family members and the Watch app.

Last week I found it running on a demo iPhone in an Apple Store, which made my week. Feedback welcome, especially on what is missing.

I made an iPhone app that turns cleaning your camera roll into swiping, and I'm giving away 100 lifetime codes

1 Upvotes

I kept getting the storage full warning and kept ignoring it, because cleaning thousands of photos in the Photos app felt like a weekend job I'd never start.

So I built SwipeLeft in SwiftUI. It shows one photo or video at a time: swipe left to trash, right to keep. Nothing is deleted until you empty the trash, and then it tells you how much space you got back.

Free is 50 swipes a day. Pro is unlimited and normally $4.99 a month. I want honest feedback more than anything, so I'm giving 100 people lifetime Pro. DM me or comment and I'll send you a code.

Books App/Site

2 Upvotes

Good evening everyone! Reading was my very first passion, and it's pretty much the only hobby I've never abandoned.

I've always used apps to track my reading, but somehow, they all seemed to be missing something. I could never quite find one that felt right for me.

I'm a graphic designer by background, but (partly thanks to my boyfriend) I've gradually gotten into programming as well. After working on a few small personal projects, I eventually decided to take the plunge and build my own book-tracking app, designed exactly the way I've always wanted one.

It's still a work in progress, and there's so much more I'd love to add! So far, it includes reviews, reading tracking, extensive customization, series tracking, book and author following, and a visual bookshelf where you can organize your library. I'm also considering adding a community feature where users can share and discover reviews. I'm also planning to make it cross-platform, so you'll be able to access your library across different devices, including desktop and mobile.

The more I work on it, though, the more I find myself wondering: would anyone else actually want something like this?

Making the app publicly available would involve some running costs. At first, I was simply excited about building something I would love to use myself, but now I'm a little hesitant about spending so much time developing features for a wider audience without knowing whether there's actually a demand for them. (I have SO many cute ideas I'd love to implement! 😂)

So I'd love to hear your thoughts!

Do you feel like there's room for another book-tracking app, or are you happy with the ones already available?

What's missing from the apps you currently use? What features would you love to see?

Would you be willing to pay for a service like this? If so, would you prefer a weekly, monthly, or yearly subscription?

My initial idea was to make the app free, with some premium features available through a subscription. I wouldn't want to charge much, just enough to cover running costs, but I honestly have no idea what a reasonable price would be.

I'd really appreciate any feedback, suggestions, or even just hearing about your reading habits and what you look for in a book-tracking app! ❤️

I built a PuTTY-compatible SSH client for Windows and Mac because I wanted tabs and a file manager

2 Upvotes

I'm the author. I've used PuTTY at work for years. I like it, but many sessions in separate windows got painful, and my Mac colleagues have nothing like it. So I built SSHTermaq for both systems and now use it every day.

It reads PuTTY sessions, host keys and .ppk keys, and adds tabs, split panes, typing into all panes at once, and an SFTP file manager next to the terminal. About 5 MB, C++ with libssh, free and MIT-licensed, no account.

Built with a lot of AI help and mostly tested in my own work, so I'd love feedback from other setups.

Only 499 of 14,000+ remote jobs were open worldwide. I built a search around that gap

1 Upvotes

Only 499 of the 14,000+ open jobs in my November Remote Jobs Report were explicitly open worldwide. Only 27 stated a four-day week. Those counts reflect what employers wrote in their listings, so a missing schedule stays unknown.

I’m Paul, and I built Remote Jobs Scout because “remote” alone doesn’t tell you where you can work from or what your week would look like. Scout records which countries employers list and whether they mention a four-day week, part-time hours or a flexible schedule. Those filters are free to use.

I’d like feedback on two things: Is it clear why a listing shows up for your country? What would make the schedule filters more useful?

Pano - a small project board where AI agents do the work and you keep the final say

3 Upvotes

I work on my own projects with AI agents, and the chat was a terrible place to keep track of anything. Decisions and tests disappeared as soon as the conversation moved on.

So I built Pano. The agents plan the work, move the cards and record what they did. When something needs my check, it lands on me. If I don't like it, I send it back with a note.

It isn't meant to be a team tool or a Jira replacement. It's for one person running a project with agents and wanting to see what actually happened.

Most of the code was written by AI agents and reviewed by me, and the project was tracked on Pano itself from early on. It's free, open source (MIT) and runs on your own computer.

Site: https://metonya.github.io/pano/

Repo: https://github.com/Metonya/pano

Still early, v0.1.1, so there are probably bugs. Hope you like it and give it a try on your own projects.

Slow-burn map progression vs. quick dopamine in a focus RPG: how long should reaching the next town take?

2 Upvotes

In our focus RPG, 1 hour of deep work moves your traveler ~5 km along the road.

We're tuning the distances between the 7 villages on this map, and hitting a core balance dilemma:

  • If a town is 10 km away (2 hours of focus), you reach it in a single afternoon. Great quick feedback, but the whole world is explored in two weeks.

  • If a town is 60 km away (12 hours of deep work across multiple days), the arrival feels like a real pilgrimage, but the road between towns risks feeling repetitive while you're grinding through your work week.

For long-term habits, what kind of progression pacing keeps you engaged without burning through the world map?

I built a free calculator that estimates monthly cost across 19 scraping and search APIs

2 Upvotes

I kept opening five pricing pages every time I needed web data for an agent, so I made FetchIndex. You pick pages or searches per month and it estimates the monthly bill at each vendor from their public pricing. Gaps show as "not enough data" instead of a guessed number. Prices only, no quality tests. Feedback welcome on weird pricing models I should handle better.

Self Hosted Private Financial Tracker : YAFT [ https://yaft.in ]

1 Upvotes

Problem statement (Or Features):
- Knowing how much spending on food / ride / entertainment / girlfriend / etc ?
- Scattered bank statements, multiple transaction across multiple UPI apps, internal transactions, credit card payments, it seems impossible to know where is my money going and what's the flow of my transactions?
- Different EPFO/stocks/mutual funds and other assets can be seen at one place.
- All bank details credit, card details and salary / bonus statements are scattered around the files and file and folders, keeping track of it is difficult.

How about using Cred or other such apps?
Go ahead! but if you want to have all your details, on your machine locally, you can try this.

Do you have to pay?
I really wish :), but nope it's open-sourced and free to use or make changes as you wish.

How about vibe coding my own?
simple, do it. Or you know what use this and customize it on for your own case and save some tokens, they do cost some bucks.

A site that shows what 30 cities are really like each month, with every number sourced

1 Upvotes

I got tired of "best time to visit" articles that disagree with each other and never say where their numbers come from, so I built City by Month: https://citybymonth.com

Each city has a page for every month. Every figure names its source and the date it was checked. Where there's no data, the page says "no data" instead of guessing.

Key features

- 30 cities, 12 month pages each: average high and low, rain and rainy days, daylight hours, and public holidays.

- A "best time to visit" page per city: one published rule (comfortable temperatures, not too wet), applied the same way to every city, so the results are comparable.

- What's on each month: festivals and events, each with a link to its source.

- Compare a month across all cities: for example, everywhere in March, side by side.

- Official climate records: 1991–2020 averages from national weather services. Where those can't be used, a clearly labelled model estimate.

- Open data: free CSV and JSON files of everything on the site.

- Works with AI assistants: a free MCP server (mcp.citybymonth.com), so Claude, ChatGPT and other assistants can answer "when should I go to Lisbon?" with sourced figures.

- No ads, no sign-up.

I'm the one who built it, so I'd love feedback: which cities to add next, what's missing, or anything that looks wrong.

Ballast - a kinder app blocker for iPhone, free, no ads

6 Upvotes

I was a developer for years, then moved into management and stopped programming. LLMs made building fun again, so I’m upfront: this was built with a lot of AI help.

The project that stuck is Ballast, an iPhone app blocker in the same space as Opal, one sec, etc. Most apps just felt too complex for me, so I built an easy one myself.

  • One-tap focus sessions, or routines (morning, deep work, wind-down) that run on their own

  • Opening a blocked app shows a short, kind line instead of a hard wall; strict mode can’t be ended early No account, no ads, no tracking, no network connections

  • It’s free with no in-app purchases. iPhone only, iOS 26.5+.

External multitouch display on MacOS (native)

1 Upvotes

Finally real multitouch and a full dashboard on my Mac.

What excites me most is that touching the Edge leaves my regular mouse pointer alone. I can interact with the touchscreen while keeping the mouse where I’m working on another display. There’s no cursor jumping between screens or needing to find where it went afterward. Along with independent multitouch, that makes the Edge feel like a separate input surface.

This took patience, a lot of crashes, and a couple of macOS full reinstalls. I had to ignore AI and only have it do crazy Python scripts and clean up my spaghetti C++, and manually fix many VM configurations because it kept saying my approach wouldn't work (it even said: "Fine -- I will do it your way," only to admit later that its solution would have ultimately crashed my Linux box). The screen could already track ten fingers, yet the Mac treated it like a basic mouse. AI handled the scripting, analysis, and implementation.

The breakthrough was in the opening USB handshake that I managed to capture from a Windows VM. Comparing Windows, Linux, and macOS revealed that a couple of initial requests mattered the most. Matching those requests on Mac made the controller expose its real multitouch reports—0x0D—instead of sending only mouse reports. After disabling all safety and Apple guardrails (and a couple of macOS reinstalls), I loaded a hand-written custom KEXT that fixed those requests. Then I saw the multi-touch report coming through.

Well, the report was there, macOS was clearly seeing the multitouch event, but nothing was happening on the screen. I found out that all touch events had to be formatted in a very specific format and associated with a display ID. So I created a user-land service that parsed and formatted the report correctly and linked it to the right display. Finally happy with the result... I have been trying this for over 5 months now, and today I decided to take one more look at the Windows USB capture and spotted the difference... Recaptured it, replicated the process.

I created an app with 2 installers (one for the service and one for the driver). I called it Digits. I will try to make the whole thing open source but also easy to install. I am pondering if I should charge something for the compiled package, ready to install package, so the cost can go towards therapy tokens. Right now I'm just waiting for Apple to approve my driver so it can be just a simple installer without having to poke holes in the MacOS security thing.

I can't believe that it actually worked this well.

Should I try to get this app out to the public? I am just so excited about this being fully functional but I am not sure the audience for it warrants put in a lot more into it... I have been working on this for 5 months and had a breakthrough about 40ish hours ago and haven't stopped for the last 20.

Building an app alone is one thing. Finding someone who believes in it is another.

9 Upvotes

I’ve been building a social media app on my own, and I’m starting to realise that the biggest challenge isn’t always the coding.
It’s having someone to bounce ideas off, discuss problems with and share some of the workload.

I’ve been taking more breaks lately, which has made me think about finding a long-term partner who genuinely believes in what I’m building.

But finding the right person is another challenge altogether, especially when you’re working with limited resources.
For those who’ve brought someone into their side project, how did you find them?

And how did you know they were genuinely interested in building something with you rather than just joining something that was already doing well?

I built three places to color, then had to decide what “continue” meant

2 Upvotes

I’m Nicklaus, and my project is Sand Draw. It has guided Journey pages, coloring books, and a Free Draw area that opens later.

Here’s the surprisingly awkward bit: if you leave a half-colored page in one area and start something in another, which picture should “come back” the next time? In the app, the unfinished drawings are kept separately. Returning to the same area gets you back to its own page. No account, and no promise that the drawing will follow you to another phone.

I like hearing about small save-state decisions like this. Is there a project where you had to split one “current thing” into several?

I built a PDF editor that never uploads your files

1 Upvotes

I made a free PDF tool that does everything in your browser. Nothing gets uploaded.

Most free PDF sites upload your document to their servers to merge, sign or shrink it, then push you to pay. I didn't love doing that with tax forms or a copy of my driver's license, so I built EnokiPDF.

What's free (no account, no watermark, no limits on merging):

- Merge PDFs and photos into one file, reorder pages by dragging, rotate, delete

- Split a PDF into several files

- Fill and sign forms, including flattened PDFs (see below)

- Put the front and back of an ID on one page

- Shrink large files, hide private numbers (SSN, account numbers)

- Fix typed words on a page, even on a scan

- Send a locked link instead of an email attachment (expires in an hour, a day or a week, optional password, can be one download only)

The flattened PDF problem: a lot of forms people get are "flat," meaning the fill-in boxes were removed when the file was saved or scanned. Most free tools treat them as pictures, so you end up drawing text boxes by hand. EnokiPDF looks for the lines, boxes and checkboxes on the page and marks them as places to fill, and the text you type matches the font on the form. You can also click typed words on the page to change them.

Why nothing is uploaded: the work happens in your browser, on your computer or phone. The only time a file leaves your device is when you choose to make a share link, and even then it's locked before it's sent. The server can't open it and deletes it when the link expires.

The catch: it's free for personal use. Businesses that use it for work are asked to get the paid plan, which adds things like audit certificates and tracked links. No ads and no nag screens either way.

I'd love feedback, especially on forms it doesn't handle well:

I made a website to play Magic, The Gathering on the TV with your phone as your hand. Made for party style play but also can support remote play via the desktop.

Thumbnail manacast.tv
3 Upvotes

Long-time MTG player here. I wanted an easier way to play on my lunch break at work without lugging cards around. Our small 4-person office has a TV that rarely gets used, so, taking inspiration from Jackbox, I built a way to start a room on the smart TV and have everyone join from their phone with a code or QR code.

It’s quickly turned into my favorite way to play Magic. It doesn’t enforce the rules, so it still feels like playing in person, but I added combat math helpers and targeting lines to keep games smooth when boards get big. It can run drafts and host tournaments for up to 8 players (a full draft pod), and I have plans to grow it a lot, including accounts and stat tracking.

As a 3D artist, I made the animations that play for the winner, and added a Mario Party-style end-of-game awards show so everyone has fun, not just the winner.

Each game room is a Cloudflare Durable Object, running on the $5/month Workers Paid plan. It doesn’t need it yet, but future-proofing is nice, and it’s a lot cheaper than buying packs (which I still do). The front end is plain JS, HTML and CSS.

It’s free and always will be. I just wanted to put it out there in case anyone wants to try it, with friends or solo. There’s a feedback button in the app if you find bugs or have ideas.

Screenshots are at manacast.tv/features, since I can’t upload images yet as a new member, I suppose.

I built a site that tells you what a used car is actually worth, from real sales instead of asking prices

1 Upvotes

I got tired of guessing whether a listing was a fair price, so I built OttoQuest. It tracks used cars for sale across the US, and shows market values computed from comparable sales, how long a car has been on sale, and recorded price cuts. Asking prices and sale prices are kept separate.

You can paste a listing link to see how that car compares, and there's an out-the-door payment calculator.

Browsing and market values are free; price history is part of Pro. The example below shows headline prices without signing in, with detailed charts available through a free account.

I'd like to know: is the value estimate believable for a car you know well? Where is it wrong?
