Show HN: I brought back Airbnb categories
I miss airbnb categories. It was fun and I loved being able to just browse thorugh cool listings. I'm not exactly sure why they removed it. Then, a couple weeks ago, they hit me with some A/B test and I had access to a "what" freeform textbox to custom filter results. Now apparently they removed that too.At this point, I wasn't happy - so I decided to look into how to bring it back. I noticed...
in general though, the goal of this tool is the one you're describing: aggregating communities that have the same topic/niche across different platforms
Show HN: I collected 70k online communities – semantic search to find your niche
https://www.pluggo.ai/find-online-communities-free
I built a social listening agent (yes, like everyone and their grandma). along the way though I realized one of the most useful parts was just finding the right communities. so I started saving them and now i have ~70k.then I added semantic search so you can find communities by meaning. the dataset grows as people use the platform.how it works- free accounts: semantic search the already saved...
Show HN: An interactive dashboard to explore NYC rentals data
https://leaseswap.nyc/analytics
historically, rentals in NYC have been pretty wild. the median 1BR in West Village as of July 2025 cost $5,750/month. about a month ago, NYC passed a law to ban broker fees which many predicted would have increased rents. I realized I had access to some original data from a previous project so I built a dashboard to help me visualize the changes and see for myself.you can filter by...
I initially had only the comments and price predictions, then added the analysis around it. I need to add more discoverability for comments to pick up though.
Didn't know people would get this triggered by this UX pattern tbh. I had it before with a modal that prompted the user to login but figured this might just be easier / faster?
I'll readd the modal though.
Show HN: Paste a Zillow URL and get a property analysis

Hey HN,I love scrolling through Zillow and spend way too much time thinking a property is gonna be my next home just to find a couple of days of research later what’s the catch.I built this property analyzer to get a quick overview of “the good, the bad, and the ugly” (love spaghetti westerns) for the property. In ~30-45s you get a pretty comprehensive analysis of the history, risks, and...
Show HN: Masterkey – A TurboTax-like platform for self-service home buying
Hey HN- Masterkey founder here. It’s 2025, and while we’re supposedly on the cusp of AGI, we still buy houses as if it’s 1925. A recent Fed study [1] found the typical 3% buyer-agent commission is inefficient (shocker) and costs American homebuyers $35B every year. That seemed broken to me, especially at a time where a whole generation is struggling to buy homes in the first place, so I built...

Show HN: I made a game to show how bad the NYC rental market is
Analytics: our painpoint with a few other search solutions was a lack of out-of-the-box insights for user behavior and common searches. We’re addressing this with Searchbase
