CommunityTube (new HBV repo, working name)

An open-source generator that turns any community's comment history (a subreddit, TabNews, a Discord export, a forum) into a HackerTube-style site of the videos that community keeps recommending, with a hosted version and sponsor slots as derivatives.

Título provisional: CommunityTube (new HBV repo, working name): make a HackerTube for any community in one command

Resumen

BriefingVerificadoHipótesis

POP 5.6 slot: a NEW repo HBV would launch on GitHub (cesarx2) to go viral and earn from derivatives. Template proof: Karpathy's HackerTube (a YouTube-style site of 6,454 videos recommended in 39,834 Hacker News comments) reached 2,863 points and 634 comments on Hacker News (Verified, HN page) within days of 2026-10-31, and its data export invited copies.…

Copies so far all target Hacker News itself (books, Chinese, personal versions); a single command that does the same for ANY community was not found in two searches (limited verification, Hypothesis). Hook: 'r/yourcommunity, as a YouTube'. Every community that gets its own Tube is a share. Derivatives: hosted 'make your Tube' (subscription), sponsor slots on each Tube priced up with traffic, PT-BR/ES communities (TabNews, Brazilian and Mexican subreddits). Risk: the trend is days old and clone-heavy, so a launch must happen within about a week.

Descripción

Repo concept (GitHub cesarx2/community-tube): a pipeline (comment dump in, labelled recommendations out, static site built with Next.js on Vercel) with adapters for Reddit data exports, Hacker News, TabNews, Discord/Telegram exports and any CSV of comments. Steps: collect comments, keep those that recommend a YouTube v…

ideo using an LLM stance label (recommend, cite, joke, criticise) as Karpathy describes, require several distinct recommenders over several months to drop one-off drive-bys (the HackerTube method as described by third parties), write a short card per video, group by topic, and render a no-login YouTube-style site where the thumbnail is a middle frame and the state lives in the browser. Playback uses the privacy-enhanced YouTube embed; no video files are hosted. Global Application: any community with a link-sharing culture can have its own Tube. LatAm Version: TabNews, r/brasil, r/mexico, Brazilian football and gaming subreddits first, PT-BR/ES interface.

Cliente objetivo

Community admins, creators and developers in Brazil, Mexico and English-speaking communities who share videos in comments

Problema

Great recommendations are buried in old comment threads; algorithmic feeds are full of slop

Por qué esta puntuación

Por qué obtuvo una puntuación menor: Trend fades and platform terms

Ventaja defensivaHipótesis

First generator + local communities + sponsor slots. Early open-source position, PT-BR/ES community packs and a gallery of Tubes people share. Code is trivially forkable; the moat is speed, the gallery of Tubes and contributor adapters. Hypothesis.

Jobs to be done

When my community keeps recommending videos in comments I will never re-read, I want a clean Tube of what they actually recommend, so I can watch trusted picks instead of the algorithm.

HXC

Lucas · 29 · Recife: Active in two Brazilian developer and gaming communities, tired of algorithmic feeds, saves links recommended by people he trusts. Frustration & buying signal: Wants the community's best videos in one place; would star a repo and might pay for a hosted version.

Construcción y go-to-market

Stack tecnológico

Cursor + Vercel + GitHub cesarx2 (one repo); Supabase; Stripe

Canales de GTM

HN, Reddit and dev.to launch with faceless assets, a gallery of community Tubes, PT-BR/ES SEO pages; no founder on camera, no paid ads

Riesgos

Riesgo principal

Trend fades and platform terms

Todos los riesgos

Value Risk: Attention — Interest in HackerTube may fade within weeks. Next: Launch inside seven days. | Usability Risk: Attention — Non-technical community admins cannot run a generator. Next: Hosted 'paste your community link' version. | Feasibility Risk: Supported — Small codebase; embeds rely on YouTube's player.…

Leer el resto

Next: Prototype on TabNews data. | Viability Risk: Elevated — Platform terms for community data and sponsor revenue are unproven. Next: Legal read on Reddit and Discord data; sponsor outreach only with Cesar's approval.

Siguiente paso de validación

Prototype on TabNews data; read Reddit/Discord data terms; star-check comparable repos

## Goal for ProductBots.ai
Turn this idea into a validated MVP plan and a first build. Start from the next validation step; do not assume unlabelled numbers are verified.

## What it is
An open-source generator that turns any community's comment history (a subreddit, TabNews, a Discord export, a forum) into a HackerTube-style site of the videos that community keeps recommending, with a hosted version and sponsor slots as derivatives.
