Ask HN: What niche task/tool websites have you built?
For example, I made a website which helps to find good cities for visa-free international meetings by estimating the cost of many people with different passports traveling from different places.
I will not link to it here suffice to say that it only got 1 HN vote likely because it is not useful for 99% of people.
What niche task-oriented / decision making websites have you built to completion? Especially, if you shared it previously but it didn't do well.

- paeselhz 3y agoRecently I've built a tool to explore Inflation data in Canada ( https://maplecpi.ca/ https://maplecpi.ca/ ). Certainly not interesting to everyone, but still gave me some insights on the current situation of the economy.
- xk3 3y agoYes! This is the kind of stuff I'm talking about. I have absolutely no use for this (but I'm sure there are a few people out in the world who would love this) and I thank you for posting
- nosecreek 3y agoLove it! I built a site to track grocery prices/inflation in Canada - http://grocerytracker.ca/ http://grocerytracker.ca/

- mtmail 3y agoIn my industry there's no standard if a position should be latitude,longitude or vice versa. Every tool wants them different, it's easy to have them mixed. https://flipcoords.com/ https://flipcoords.com/
- xk3 3y agoI also do a lot of GIS stuff and I might actually use this in the future. I agree it is pretty niche. It might be nice to support non-WGS84 coordinates
- mtmail 3y agoYou mean DMS (degrees, minutes, seconds) as input?
- xk3 3y agosure, or meters. These are common projections: - EPSG:3857 Web Mercator - EPSG:6933 https://nsidc.org/data/user-resources/help-center/guide-ease-grids https://nsidc.org/data/user-resources/help-center/guide-ease... - UTM You could just support Web Mercator, if normal or swapped are not valid coordinates, assume Web Mercator and check if they are valid coordinates. If they are swapped it will still be in the general area even if the projection is not exactly matching
- mtmail 3y agoGood and useful idea, I added DMS input now.
- mdwalters 3y agoI was inspired by GitHub Projects' new table layout to make it into a really simple to-do list website. I wouldn't say this is complete, but it does it's job. https://tables.pages.dev/ https://tables.pages.dev/
- xk3 3y agonot really niche yet but good starting point to branch off to niche tools! You should definitely consider adding save to / load from localStorage, IndexedDB, or URL. Nice thing about URL is you can send pages to other people like this: https://unli.xyz/tabsender/?links=%22open%20a%20bank%20account%5Cndeposit%20some%20money%5Cn%3F%3F%3F%5Cnprofit!!!1%22 https://unli.xyz/tabsender/?links=%22open%20a%20bank%20accou... Or use LZString https://github.com/pieroxy/lz-string https://github.com/pieroxy/lz-string like this: https://unli.xyz/html/edit.html?t=%22DwBwfALghgTgXlAdsA9OYAzAlgcwK4wCmABAMYA2UAzlQLwBE0ARuYfWMM6xxEwPYATAJ48YPAWACMqCBM4SATDLmywAZmXiwAFk3ywAVj0oIYzmdVKTKiQDJETKiADce1fccu3dh09fWtAA9jU1EtDQD9Dz9vMGDI918vBJ9Pf1UZCwsJXRSwaOSMxLTYgvSbfKTyjhMsrSM8%2BKLUmMbSqpC6-QA2dpK8sr7W5sr%2BjNqa3kERGSgWQhrsfCIwIA%22 https://unli.xyz/html/edit.html?t=%22DwBwfALghgTgXlAdsA9OYAz... An accidental page refresh shouldn't eliminate all your TODOs :/
- mdwalters 3y agoTrue. I was thinking of picking this project back up, and this would be a good addition. I think using LZString would be a good idea, as it could be able to share tables with others.

- a_bored_husky 3y agoDealing with the steep costs of internet services in my country and being an avid podcast listener myself, me and a couple of friends came up with a solution. We developed a website that works as a mirror for users' selected podcast feeds and converts the episodes into opus format, slashing the mobile data consumption that's a real concern for internet access here: https://easypodcasts.live https://easypodcasts.live It's FOSS and free as in beer.
- zeagle 3y agoThat's a great design and idea. Thanks for sharing!
- a_bored_husky 3y agoThank you.
- dendrite9 3y agoWow I like this idea at least for many conversation based podcasts. I try to download mine at home but data isn't as expensive for the times I don't. Still there are reasons to use this. I need to look into how the mirroring works, for some time I have wanted a way to subscribe to a podcast with a timeshifted start. Say from the beginning up to the date I start, or a range between 2 dates. For podcasts that have existed for a long time I find it hard to work through the back catalog in any consistent way.
- a_bored_husky 3y agoThe mirroring part is for the rss feed specifically. When a podcast is added to the website a feed is generated with the same data as the original feed but only including the processed episodes and the media links pointing to our files. Then you subscribe to that feed instead of the original using your favorite podcasts app. We have some "hidden" features like subscribing to a tag or merging many podcasts in one feed, but nothing time related.

- Syntaf 3y agohttps://wetrockpolice.com/redrock https://wetrockpolice.com/redrock Rock climbing is really popular here Las Vegas, but due to the sandstone being brittle it's both dangerous and "bad ethics" to climb after rain and risk breaking popular climbing routes. I wrote a tool that checks precipitation information from the rain gauge at the park's visitor center and displays it in an easy-to-understand manner. Nowadays the site supports a couple other rain-sensitive areas, but Red Rock is primary the reason people visit this site.
- xk3 3y agoI love this! Most important information at the top and more detailed information when scrolling down. Perfect :)
- hbcondo714 3y agohttps://github.com/hbcondo/revenut-app https://github.com/hbcondo/revenut-app I built this web + mobile app (PWA) written in React Native + TypeScript that does simple revenue forecasting for a SaaS that uses Stripe. Stripe's mobile app and others kinda do this already but some of their numbers can be inaccurate (as detailed in the repo's readme) so that made me open-source + solve an issue my own SaaS[1] has with Stripe. As mentioned in the challenge section, getting data from Stripe is slow so I've been reluctant to put this app in front of others even though it is fully functional. I actually shared this on a similar HN thread not too long ago[2] [1] https://Last10K.com https://Last10K.com [2] https://news.ycombinator.com/item?id=37156101 https://news.ycombinator.com/item?id=37156101
- xk3 3y agoInteresting! Great submission. > I've been reluctant to put this app in front of others even though it is fully functional I have a few projects like that. I've built something that works for me but I don't really want to bare the maintenance costs so I don't tell anyone about it
- JohnMunsch 3y agohttps://paperquik.com https://paperquik.com I still take notes on paper sometimes and most "paper" sites are just a bunch of pre-created PDF files. Mine creates a SVG on the fly and then can print it out from the page. While I really loved creating it and still use it myself, I wish printer support in the browsers was better. I don't have to deal with garbage like IE anymore, but nobody gives me a chance to remove automatic margins and stuff that gets printed in those margins. I can tell the user to do it manually, but much better would be a chance to prompt the user and offer to remove all of that if they OK it.
- pimbrouwers 3y agoVery neat John! Bookmarked.
- nicbou 3y agoDid you also deal with the Safari margin issues? I can't make a proper DIN 5008 template because of it.
- JohnMunsch 3y agoIn the Mac printer settings under Safari the user can uncheck "Print headers and footers" manually and that's almost sufficient for me. For reasons I've struggled with debugging, it wants to print a second blank page after the first one. As long as the user skips the second sheet everything looks OK for Safari for my app.
- Brajeshwar 3y agoWow! This is just bl**dy brilliant. I needed this. I love scribbling and think by writing a lot. I even made an Affinity Publisher template but I knew that was using a sledgehammer to kill a fly. Is this source open? Can I tinker with it?

- jorl17 3y agohttps://www.open-elevation.com/ https://www.open-elevation.com/ I know it always feels like it is "abandoned", but it isn't (it's serving millions of requests every day, especially for major iOS and Android apps!). The truth is I rarely have the time to improve upon it, especially because I've been (deep) in the red for so long it kinda affects my RoI to work on it. Nonetheless, a couple of months go I completely rebuilt the backend and managed to triple the load we can handle. Still, we're constantly overloaded and I can't upgrade the machine due to the aforementioned lack of funds. However, I am hoping to revamp the service over the next months, keeping it free, updating the docker image to a much more recent one, closing up PRs and perhaps finding ways to monetize it (again, while never making the free offer worse -- I hope to make it better, instead) (I've been saying this for years but this time I think the right conditions are there)
- tejado 3y agoPlease describe what your service is for. I had to click on the Google Elevation API on your „What is Open Elevation“ page to finally understand what your service is for.
- badcc 3y agohttps://groupreceipt.com https://groupreceipt.com Solves problem of being out at a group dinner and figuring out how much you owe the one person who inevitably put their card down. Take a photo of your receipt, it digitizes it in seconds, and gives a link to text to your friends/acquaintances. They open, click what they ordered, it proportionally adds tax and tip. No APP required, nor an account. That would be friction.

- tyroh 3y agoThis is great! I actually made another sheet in the same file to track historical changes in one of the values by manually checking based on Google's own version history. Of course, I would probably use this but the price tag isn't a match to how I'm going to use it (just for personal expenses)

- qup 3y agoI built a website to republish arrests/mugshots for my county. It's the best option for our area, and people actually use it. The county's option is really bad and doesn't show any old records, just a live "roster" at the jail. I'm not going to link it because I like to pretend I have some pseudo-anonymity here and it would pinpoint me. The stack is python workers/scrapers, postgres, and a very basic PHP template. Two views. In the past I built a lot of small poker tools, like a HUSNG push/fold calculator and a nash equilibrium calculator, that I published on free Heroku dynos, but I was pretty much the only user.

- CharlieDigital 3y agohttps://turas.app https://turas.app My wife and I were planning a trip over the holidays and it was getting out of hand on Google Docs. Ended up building a small tool over 3 days (v1) and then sharing it to Reddit on day 7. Got a bit of traction and started working on it full time over the summer, but I don't think I can figure out a business model. So enjoy an ad-free, complelety free collaborative trip planning and travel blogging tool for obsessive planners!
- xk3 3y agoI built something like that, a few times. Yes, it is very difficult to monetize something like this: - https://unli.xyz/city/calc/ https://unli.xyz/city/calc/ - https://unli.xyz/city/window/ https://unli.xyz/city/window/ - https://travel.unli.xyz/ https://travel.unli.xyz/ (no longer loads data)

Show HN: Plan international rendezvous with different passport holders https://news.ycombinator.com/item?id=35911110 https://news.ycombinator.com/item?id=35911110
- xk3 3y agoWell if you want it, it will always be available right here: https://unli.xyz/city/honeymoon/ https://unli.xyz/city/honeymoon/ The passport compatibility information is automatically refreshed on a daily basis. There are some UI quirks which take a minute or two to figure out and I'm not going to change it. The search box is somewhat unconventional because making a list of tens of thousands of cities is not performant or easily navigable so you have to search and then filter the results.
- nicbou 3y agoWhere do you get the data from? This incredibly useful!
- xk3 3y agoCity names are from Natural Earth: https://www.naturalearthdata.com/downloads/10m-cultural-vectors/10m-populated-places/ https://www.naturalearthdata.com/downloads/10m-cultural-vect... Passport data largely from https://www.passportindex.org https://www.passportindex.org with fallback to Wikipedia scraper Monetary per diem estimates come from a multitude of sources and then blended together into a interpolated raster which the backend uses to query so that there are no empty spots for cities with no data. Transit connection estimates are based on GTFS and airline sources I also expose some of this data in my other tools: - Reverse flight search https://unli.xyz/flights/ https://unli.xyz/flights/ - Gap year planner https://unli.xyz/city/calc/ https://unli.xyz/city/calc/
- Brajeshwar 3y agoOnce upon a time, I clean up a table that my team refer to for HTML entities used in HTML, CSS, and Javascript. It became surprisingly popular and I haven't touched it in years, except for moving it to my family's Github account. https://oinam.github.io/entities/ https://oinam.github.io/entities/ There are a few others, such as a tiny community informational site. People have made mobile friendly versions out of the website that I made, and the like. I gave that away, including the domain and the whole thing is now owned by that community.

- nicbou 3y agoI create little tools to help with German bureaucracy. It's a nice break from writing content, and scratches my programming itch. I built a bot to help you find a citizens office appointment, a few tax calculators, and a letter generator for specific bureaucratic tasks. https://allaboutberlin.com/tools https://allaboutberlin.com/tools https://allaboutberlin.com/docs/resignation-letter https://allaboutberlin.com/docs/resignation-letter These tools are embedded in the content wherever relevant. They remove the tedium and uncertainty from some tasks. I'm currently working on a form filler for two of my most downloaded forms. In the future, I'd like to "close the loop" by faxing the forms through an API and catching the response through a mail scanning service. Instead of mailing printed forms, you could fill a form online and get your response by email later, in plain English. If the government won't go digital, I will do it for them.
- xk3 3y ago> If the government won't go digital, I will do it for them. You are a kind human being. Your passion is overwhelming and I wish you great success. Time to abolish the tyranny of paperwork.
- nicbou 3y agoThe important half of this equation is that the website pays enough to let me take my hands off the wheel and work on fun things. This is something I'm immensely grateful for. Few people get to work on things without thinking about how they'll make money from it. Just imagine what we'd build if there were more.
