OpenStory

OpenStory breaks a pasted script into scenes with camera angles and mood, then renders frames, motion clips, music and dialogue through fal.ai. It is the MIT-licensed code behind openstory.so, built on TanStack Start with D1, R2, Workflows and Durable Objects.

Script analysis runs on a model reached through OpenRouter and also tracks continuity between scenes. Characters, locations, color palettes and lighting carry from scene to scene, and single shots can be regenerated or given variants until a sequence works. With your own Upload-Post key, a finished render can go straight to TikTok, Instagram, YouTube, LinkedIn or X. Every generation job runs as a Cloudflare Workflow; the config declares 34 of them, for images, motion, music, dialogue, character and location sheets and more. A Durable Object streams progress to the browser, app data lives in D1, and generated media goes to an R2 bucket, with a second bucket for public template assets. Four cron triggers handle upkeep such as sweeping stuck jobs and refreshing model pricing. Each deploy applies D1 migrations, and the Worker seeds its starter templates on the first request. Sign-in uses one-time email codes sent from the EMAIL_FROM address, passkeys, or Google with your own OAuth client. AI keys stay out of the deploy form on purpose: FAL_KEY and OPENROUTER_KEY can be set as Worker secrets, or each team can add its own under Settings.

Built for: Creators, marketers and small studios who want a self-hosted script-to-video tool

What you can use it for

• Storyboard a short film or ad from a written script
• Make explainer or product videos that keep the same characters in every scene
• Try different image and video models on a single shot
• Publish finished renders to social networks through Upload-Post

  The README's guided setup from a clone, which needs Bun 1.3.9 or newer. Its deploy step uses the production environment in wrangler.jsonc, which names the upstream project's own D1 database and R2 buckets, so point those at your own resources first. That environment also declares the video-export Container, which needs Workers Paid and Docker running locally.

  git clone https://github.com/openstory-so/openstory.git
  cd openstory
  bun install
  bun setup --prod

  Copy

The deploy form asks for two secrets, generated with openssl. Afterwards, either onboard a sending domain in Email Service and set EMAIL_FROM, or add Google OAuth credentials, then add fal.ai and OpenRouter keys.

Good to know

Generation needs paid third-party keys: fal.ai for images, video and audio, and OpenRouter for script analysis. Server-side video export uses a Container declared only for the upstream production environment, so button deploys do not get it. Team workspaces are marked as coming soon. A button-deployed repository is a clone, so pulling updates means adding the upstream remote by hand.
