Agenvas — Self-hosted AI creation canvas

What

Agenvas is an open-source, self-hosted AI creation canvas for text, images, video, audio, and agents. It is positioned for creators, small teams, and single administrators who want one workspace for generation, reuse, editing, and approval instead of moving assets between separate tools. It is MIT-licensed and runs via Docker Compose.

Features

• Card-based infinite canvas: every asset is a card; users can drag, box-select, connect, auto-arrange, upload local media, and see relationships at a glance.
• Per-card multimodal generation: text, image, video, and audio runs support queuing, cancellation, regeneration, and full version history.
• Agent collaboration with approval: agents read bound context, edit text, place cards, and submit media proposals that run only after user approval.
• Reusable creative assets and image processing: project resources, personal asset libraries, prompt templates, media styles, and mixed reference inputs; images can be annotated, cropped, rotated, mirrored, upscaled, and depth-extracted, with AI edits where configured.
• Self-hosted administration and model choice: administrators configure OpenAI-compatible endpoints, media adapters, storage (local or OSS/COS/S3), task and call records, and project manifest export; published capabilities determine what users can run.

Helpful Tips

• Deploy with Docker Compose v2 on macOS/Linux, Windows CMD, or PowerShell; the first image pull can take a few minutes, and the deployment directory should be kept for later maintenance.
• Complete admin setup on a controlled network before internet exposure; setup completion is recorded permanently in the database and does not reopen after restarts.
• Configure model endpoints and media capabilities before creating projects, and run the tool-calling diagnostic before using agents because user-visible operations depend on what the administrator publishes.
• Back up the database, media, configuration, and encryption key before updates; avoid docker compose down -v, which deletes data and keys.
