Why it mattersA marketing team pays for Buffer, Opus Clip and a reply tool. 37studio does the three jobs for free, with the team's own API keys.
A small marketing team pays for three AI tools. Buffer or Hootsuite schedules posts. Opus Clip or Captions makes short videos. A third tool handles replies. 37studio is one open-source desktop app that does all three jobs, with Claude Code doing the work. The repository is six days old and has reached 110 stars.
Shaitrish, a software team in Dhaka, published the project under MIT on 23 October 2026. The README calls it an AI video studio and social desk. It runs on the user's own computer. The user brings their own API keys. They pay the AI provider directly. The app shows the per-project cost in US dollars.
What it does
The app posts to nine social networks: Facebook Pages, Instagram, YouTube, TikTok, LinkedIn, X, Pinterest, Bluesky, and Mastodon. It handles messages on Messenger, Instagram, and WhatsApp. A brand library and a knowledge base built from a website guide the content. An inbox view brings messages and comments together with AI-drafted replies, which a human sends. Posts can run on a schedule or on an Autopilot that posts on its own.
How the videos are made
The format is "HyperFrames". Each video is an HTML page with timing attributes on its elements. Claude Code writes the HTML. The project then renders the page frame by frame with headless Chrome and encodes the output with ffmpeg. Local transcription uses faster-whisper. The system does not call a text-to-video model.
The approach has a plain consequence. The whole video is in HTML. A brand can edit the look the way it edits a web page: fonts, colors, exact layouts, custom components. Nothing in the final clip is a locked template. Nothing is a stock style picked by a hosted tool.
What it does not do
The README lists its own limits. No image-only post support. No Threads or Reddit. YouTube uploads stay private until Google approves the app for public posting. TikTok asks the same. Posting to Instagram still needs a Facebook Business connection. The project is version 0 and the repository has 75 commits.
The honest story is for a small team already paying for three AI tools. Replacing them with a free self-hosted project is possible. The setup takes time. The project is new enough that a reader is signing up to be an early user. The upside is a video pipeline a brand can shape to its own look. A hosted service picks the look for you. The downside is the platform approvals. A hosted service has done them under its own name. A self-hosted app does them once per company.
