Lumio
Social that makes you smile
Hey Indie Hackers,
Iām the founder of Lumio. Today, we ripped off the band-aid: Lumio is officially open-signup.
For those who haven't seen my dev logs, Lumio is an "un-serious" alternative to X/Twitter. We are betting that people are tired of "The Town Square" (arguing/politics) and want a "Digital Backyard" (hanging out/hobbies).
The "Scary" Part of Opening Up
The biggest risk with a "positive" social network is that it only takes ~5% of users to turn it toxic. When you open the floodgates, you usually drown.
To solve this without hiring an army of moderators we couldn't afford, we built a new Intelligence & Safety architecture in v1.5.5.
The Tech Stack Updates (v1.5.5)
We aren't just using standard moderation APIs. Here is what we shipped to keep the vibes clean at scale:
Two-Stage AI Safety:
Pre-Post (Edge): As users type, we analyze content in real-time to generate smart emoji suggestions and flag potential issues before the post exists.
Lumio Sentry (Post-Publish): Our new heavy-lifting system monitors media and text to automatically detect policy violations, issue warnings, and enforce suspensions.
Infrastructure Overhaul: We completely rebuilt the AI core for lower latency. All AI features now run through optimized backend functions, making the app feel "instant."
Respectful Notifications (Smart Digests): Real-time emails are the enemy of retention. We built a batching system that sends "Smart Digests" only twice a day (Noon and 7 PM). It reduces spam and server load simultaneously.
Direct Messages: Finally shipped DMs, but with a privacy-first approach (granular control over who can message you).
Why we didn't stay "Invite Only"
Marketing wisdom says "keep the scarcity." But honestly? The world feels heavy right now. People are deleting their socials because they are exhausted.
We decided that gatekeeping "fun" felt wrong. We want to see if we can scale a community that stays chill even as it grows.
The Ask
Iād love for this community to roast my onboarding flow or poke holes in the new Sentry system.
Tech Stack: Supabase, React, Deno Edge Functions, Azure AI.

Let me know what you think. Is "Un-serious" a viable moat in 2026?
I'm one of those people who are tired of everything being so serious on social media these days. I'm sick of politics, crazy un-fun arguments, being yelled at every other post, and I think you get the point..
I just want to see the bright side of everyday people and funny things shine like they are supposed to. That's why Lumio exists. To be social media that makes you smile.
