Moment before disaster🤣

Here's 60 frontend project ideas you can build in the AI era Have fun.

Developers be honest... which domain extension gives startup vibes instantly? 1) .ai 2) .com 3) .io 4) .app 5) .dev 6) .cloud 7) .sh

Un chino creó un sistema de agentes en Claude Code para vender landing pages a pequeños negocios y, trabajando completamente solo, atiende unos 47 clientes al mes cobrando alrededor de 400 dólares por cada uno. Construyó 7 agentes sobre Claude Sonnet 4.6 capaces de analizar Google Maps en ciudades pequeñas, detectar negocios sin web o con páginas totalmente desactualizadas y llevar cada oportunidad hasta un mockup terminado, un video promocional y un mensaje de prospección listo para enviar. Sin asistentes. Sin equipo comercial. Sin SDRs. Solo él, un MacBook, un iPhone y una API key. Mientras agencias tradicionales mantienen equipos completos para manejar el mismo flujo de trabajo, sus únicos costes reales son tokens y suscripciones a Lovable, Higgsfield y Calendly. Los 7 agentes funcionan coordinados por un orquestador en Claude Code Router. El sistema consume unos 3 millones de tokens diarios y el gasto medio en API ronda apenas los 480 dólares al mes. Todos trabajan mediante servidores MCP y comparten estado usando el sistema de archivos, evitando problemas de concurrencia y memoria compartida. Incluso uno de los agentes vive directamente en su iPhone y responde leads mientras él está en el metro, en un taxi o caminando. Este fue el prompt principal que configuró: “You are the orchestrator of a solo agency that sells ready-made websites to local businesses…” La clave es que el sistema entiende perfectamente qué es, cuáles son sus límites y qué objetivos debe cumplir. Sabe que debe encontrar leads automáticamente. Sabe que debe convertir cada oportunidad en una landing, un video y un mensaje comercial sin intervención humana. Y sabe exactamente cuándo debe involucrar al dueño. El sistema funciona 24/7: Scout analiza unos 220 negocios diarios y deja 30 leads nuevos en cola. Diagnoser genera diagnósticos y mensajes personalizados para cada lead. Builder crea entre 3 y 5 landing pages completas para los mejores prospectos. Filmer produce un video vertical de 10 segundos para cada propuesta. Pitcher envía unos 30 mensajes diarios en 4 canales distintos con una tasa de respuesta cercana al 14%. Checker revisa automáticamente todos los mensajes antes de enviarlos. Solo cuando una operación supera los 3.000 dólares o el ratio de respuesta cae por debajo del 12%, el sistema despierta al propietario. Y si en ese momento está en el metro o en un taxi, el agente Mobile responde automáticamente al lead interesado, agenda una llamada en Calendly y devuelve el lead a la cola. El dueño solo tiene que pulsar “aprobar” y entrar a la reunión. Algunos logs reales del sistema: “218 negocios analizados en Austin, Denver y Miami. 34 sin web, 19 con webs de 2014 y 6 con reseñas pidiendo rediseño.” “30 mensajes enviados. 14 respuestas. 5 positivas. 3 Zooms agendados.” “Landing page creada para una clínica dental. Responsive. 5 secciones. Video en render.” “Acuerdo de 3.400 dólares supera el límite aprobado. Enviando para revisión manual.” Y lo más loco es que no tiene servidores propios ni backend dedicado. Solo un sandbox local, un router MCP, una API key de Claude y esa misma clave conectada a su iPhone. De todo lo que he visto este año, probablemente sea el ejemplo más limpio y eficiente de una agencia unipersonal automatizada: 480 dólares al mes en APIs. 18.800 dólares de ingresos. 7 prompts. Un sistema de archivos. Y un teléfono en el bolsillo. Guarda esto antes de que sea tarde

Here are 10 GitHub repos that quietly print money while you sleep. 1. Cal. com Open-source Calendly. Fork it, white-label it, sell to dentists and lawyers for $200/month. The founders hit $5M ARR in 3 years doing exactly this. Repo → github.com/calcom/cal.com 2. Plausible Analytics Privacy-first Google Analytics. Self-host it, resell to agencies for $50/month per client. Two founders bootstrapped this to 7 figures. Repo → github.com/plausible/anal… 3. Ghost Open-source Substack with 100% margin. 1,000 readers at $5/month equals $60,000 a year. Forever. Repo → github.com/TryGhost/Ghost 4. n8n Open-source Zapier. Sell automation services for $500-$2,000 per setup. n8n raised $14M because the agency model behind it works. Repo → github.com/n8n-io/n8n 5. Supabase Free Firebase replacement. Build a SaaS in a weekend, charge $29-$99/month. They raised $116M for a reason. Repo → github.com/supabase/supab… 6. Medusa Open-source Shopify. Take 5% on every sale forever. Zero rev share to Shopify. Repo → github.com/medusajs/medusa 7. AppFlowy Open-source Notion. Sell self-hosted to enterprises worried about data privacy. They raised $30M because this market is massive. Repo → github.com/AppFlowy-IO/Ap… 8. Coolify Open-source Vercel and Heroku. Charge developers $20/month to manage their deployments. Replace their $200 Vercel bill. Repo → github.com/coollabsio/coo… 9. Listmonk Open-source Mailchimp. Send unlimited emails for the cost of an AWS bill. Resell to agencies at 10x markup. Repo → github.com/knadh/listmonk 10. Penpot Open-source Figma. Sell self-hosted design tools to agencies who refuse to upload client files to the cloud. Repo → github.com/penpot/penpot The difference between developers who build features and developers who build businesses is one decision. Pick one of these. Fork it this weekend. Ship it next week. The founders behind these repos already proved the model. Save this. Share it with the developer in your life who deserves to break free. 100% free. 100% open source.

Someone built a tool that lets Claude Code autonomously test your entire IOS app It navigate your entire app, opens every screen, tests every flow, reads the debug logs, and hands you a structured bug report. one prompt and that's it

Vibe coders are getting sued. People are launching apps with real users but skipping the boring stuff that can actually kill the product. A developer with 20+ years of experience just shared the pre-launch checklist every AI builder should run: → privacy policy if you collect user data → know where user data is stored → check security headers → scan against OWASP basics → look for SQL injection / XSS / auth issues → make sure .env values are not leaking → check API responses for sensitive data → remove secrets from logs → never expose API keys in frontend code → move keys server-side or behind a proxy → add rate limits before someone burns your API bill This is what most vibe coders are missing. AI can help you build the app. But if you launch without security, privacy, and abuse checks... you didn't ship a product. you shipped a liability.

Do you prefer coding on a MacBook or Windows laptop?

@RaeAlisa_ @lucent_ai Codex is far superior Claude is retarded

to celebrate 3 months since lauching @lucent_ai, we're giving away 5 Codex Pro / Claude Max plans 🎁 to enter, like this post + comment which one you'd pick (codex vs claude) winners will be selected from comments in 5 days 🫶

Zig is going to become once again a niche language. Also how did they do this so fast. Has to be slop

Someone built a collection of 263+ open source animated icons that actually move with intent 😭

GPT 5.5 Codex is insane. i know literally NOTHING about coding. ZERO. and i just built 3 fully functioning web apps in 30 minutes. http://localhost:3001/ http://localhost:8000/ http://localhost:5000/ Check it out and give feedback

@fuzzzypan No ones falling for this AI generated trash you're using to get attention for your app. You're just gonna destroy your trust like this. Delete your account.

My app just made $3k in revenue🥳🥳🥳🥳

It's becoming disgustingly obvious... Almost everyone I bring on the channel did the same thing. THEY COPIED PROVEN APPS copied a proven app that shut down copied a proven app and switched the niche copied a proven app and added AI features copied a proven app and made it open source copied a proven app's marketing strategy i share this not to get you to watch my channel I SHARE THIS TO WARN YOU if your app idea is new, different, and/or based on something unproven (and you're not in YC or raised money) then BE CAREFUL!

@michael_ptl Bro I built that web scraper for u and havent responded since @michael_ptl

I built a cross-exchange, all-in-one trading tool for Polymarket — the exact kind of advanced system that quant traders at Jane Street write behind NDAs and never release publicly. I made it. No downloads required — just a simple registration and you’re ready to go. Link: polymgloss.app/?ref=5GR6IwgG In just 14 days I made $32,400 simply by copying the trades of a Chinese student who turned $0.90 into $408,292 on Polymarket in only 48 hours. On top of that, I’m now trading using ultra-precise AI signals powered by the open-source MiroFish engine inside Polymgloss — and it’s absolutely lethal. A friend of mine who develops AI for prediction markets (GENESIS-AGI) told me about Polymgloss and gave me an invite link. When I tried it… my jaw literally dropped. Here are the killer features that make any trader’s eyes pop: One-click copy trading of the most profitable Polymarket traders Smart AI powered by MiroFish that delivers highly accurate signals across any market Most of my even small trades are closing in profit (my current win rate is insane) Works on every type of market: crypto, politics, sports, events, and more
