Show HN: Radius – A Meetup.com Alternative

Original Article

Hacker News Discussion

📝 Discussion Summary (Click to expand)

Three prevalent themes in the discussion

  1. Positioning as a simpler, more flexible Meetup/Luma alternative with a unique “Activities” feature
  2. radius89: “we're more of a competitor to Meetup.com… trying to keep Radius a bit simpler and more flexible for organisers.”

  3. yosh102: “I like that someone can just say ‘I’m cycling next week,’ let people join, and figure out the time afterwards instead of creating a fully formed event upfront.”

  4. User‑experience and discoverability pain points (landing page, filtering, onboarding flow)

  5. weitendorf: “Do not implement any more documentation/pricing/marketing until you've really nailed down the UX… It helps to follow actually users… think through the steps/impression they'd take from your landing page to completing their task.”
  6. sram1337: “For an app called radius, it took longer than expected to find activities near me. Showed me a lot of info I wasn't interested in at all.”

  7. weitendorf (later): “Please create a better UI and make it easier to view events / try posting one before signing in.”

  8. Challenges of gaining critical mass and overcoming inertia from existing platforms (WhatsApp, Facebook groups, Meetup)

  9. hamedb: “why would someone switch from direct communication (WhatsApp groups, Facebook groups..etc) to a dedicated platform.”
  10. AIorNot: “The problem with this is not technology- its the lack of interesting meetups i want to join in my city.”
  11. radius89 (reply): “That's part of why I've made the Activity feature – to give individual users something useful to do even before we have that critical mass of established groups.”

🚀 Project Ideas

ActivityPost – HN‑style local activity board

Summary

  • Lets users post a quick activity request (e.g., “I’m cycling Saturday, anyone join?”) with optional time/location and see nearby posts in a card feed.
  • RSVP without creating an account; optional account for managing your own posts.
  • Core value: frictionless, real‑world‑first social planning that feels as easy as posting on HN.

Details

Key Value
Target Audience Casual locals, hobbyists, spontaneous planners looking for impromptu meetups
Core Feature One‑click activity posting with geotagged cards and RSVP
Tech Stack React + Vite, Node.js/Express, Postgres, Mapbox GL JS, WebSockets
Difficulty Medium
Monetization Hobby

Notes

  • “VeryGoodMorning: I think it makes it too complicated to post a meetup request. It should be as easy as here on HN:” – validates the need for ultra‑simple posting.
  • “yosh102: Seeing the activity flow made this click for me. I like that someone can just say ‘I’m cycling next week,’ let people join, and figure out the time afterwards.” – shows the activity‑first workflow resonates.
  • Potential for discussion: how to moderate posts, prevent spam, and boost critical mass via local community seeding.

RadiusMap – map‑first events directory

Summary

  • Map‑centric landing page with a search bar and distance/category/date filters; events/groups appear as pins.
  • Click a pin to see details, RSVP, add to calendar, or visit the group page—all without logging in to browse.
  • Embeddable widget lets groups show their upcoming events on any site.
  • Core value: instantly see what’s happening nearby, eliminating irrelevant global listings.

Details

Key Value
Target Audience Organizers and attendees who want to discover local events quickly
Core Feature Interactive map with real‑time filters and instant event cards
Tech Stack SvelteKit, Supabase (Postgres + auth), MapLibre, TailwindCSS
Difficulty Medium
Monetization Hobby

Notes

  • “weitendorf: Please create a better UI and make it easier to view events / try posting one before signing in. Something card‑based where I can quickly type in my location and see what events are nearby.” – directly addressed.
  • “atmanactive: What's the point in showing me events half way across the country? Is there a narrow‑down filter available?” – solved by distance‑first map view.
  • Encourages community discussion on ideal filter defaults, UI polishing, and monetization via premium analytics for organizers.

GeoRSS Feed – decentralized event syndication

Summary

  • Provides an RSS/Atom extension (e.g., <georss:point>) for event location; groups publish their events via existing RSS feeds.
  • A lightweight reader PWA aggregates geo‑enabled feeds and shows events within a user‑chosen radius.
  • Core value: lets existing groups stay on WhatsApp, Facebook, or newsletters while becoming discoverable through an open, standards‑based feed.

Details

Key Value
Target Audience Community organizers, newsletter publishers, local clubs seeking broader reach without new platform
Core Feature Geo‑enabled RSS feed + nearby event reader
Tech Stack XML/GeoRSS spec, Node.js validation service, Svelte PWA, IndexedDB for offline caching
Difficulty Medium
Monetization Hobby

Notes

  • “utopiah: Makes me wonder if an RSS feed with a namespace extension for a GPS coordinates field would be enough, with a basic Web page client with a radius limited…” – matches the proposal.
  • “AIorNot: The problem with this is not technology- its the lack of interesting meetups i want to join in my city.” – a decentralized feed can surface hidden events from many sources.
  • Sparks discussion on feed adoption, handling duplicates, and potential for federated event discovery akin to ActivityPub but simpler.
