Toonflow-app

Toonflow is an open-source Electron desktop application that automates AI-driven short-form video production from text input (novels, scripts). It orchestrates scriptwriting, storyboarding, character generation, and video synthesis through a three-tier agent architecture with local vector-based memory and pluggable LLM/image/video model suppliers.

What Toonflow-app is

TypeScript/Node.js + Electron + Vue 3 desktop app featuring multi-agent orchestration (decision/execution/review layers), local ONNX-based semantic memory, event-graph-driven narrative adaptation, skill-file-based prompt management, and a programmable supplier system for model integration without code restart.

Quickstart

Get the Toonflow-app source

Clone the repository and explore it locally.

terminalbash
git clone https://github.com/HBAI-Ltd/Toonflow-app.gitcd Toonflow-app# follow the project's README for install & configuration

Best use cases

Rapid Short-Form Video Production

Teams creating batch short-drama content from novels or scripts; workflow reduces manual storyboarding and asset generation cycles. Demonstrated 2-hour turnaround in README example.

Literary Adaptation Experiments

Publishers or content studios testing film/drama adaptation feasibility at low cost before green-lighting production. Event-graph extraction preserves narrative coherence across long source texts.

In-House Content Generation with Custom Models

Organizations with proprietary LLMs or image/video models; programmable supplier system allows TypeScript logic editing in UI without recompilation, enabling rapid model swapping and multi-vendor orchestration.

Implementation considerations

  • Model supplier configuration (LLM, image, video) is mandatory in settings center before any content generation; vendor API credentials and rate limits must be managed externally.
  • Project workflow assumes iterative refinement: chapter extraction → script generation → storyboard creation → video assembly. Teams should plan content pipeline and review checkpoints accordingly.
  • Local ONNX vector database for persistent memory requires adequate disk/RAM; no documented resource scaling guidance or multi-project isolation.
  • Skill file (Markdown prompts) and supplier TypeScript logic are modifiable in-app; changes take effect immediately but no version control or rollback mechanism noted.
  • Demo cost (~¥130 for 2-min output) depends on chosen model providers; production budgets must account for image/video generation costs, which dominate the bill.

When to avoid it — and what to weigh

  • Requirement for Real-Time Collaboration — Desktop Electron app with no mention of multi-user collaboration, version control, or server-backed sync. Single-user workflow only.
  • Need for Production-Grade Video Quality Guarantees — Output quality depends entirely on external model providers (Seedance, GPT Image, Claude). No quality assurance, watermark removal, or post-processing pipelines documented.
  • Strict Regulatory/IP Compliance Requirement — No mention of audit logging, data retention policies, GDPR compliance, or intellectual property tracking. Bulk content generation may expose liability if source texts or output licensing not carefully managed.
  • Windows-Only or Linux-Only Deployments — Electron app claims cross-platform support but no explicit OS compatibility matrix provided. Testing required for your target OS.

License & commercial use

Apache License 2.0 (permissive). Permits commercial use, modification, and distribution under Apache 2.0 terms. Full license text required for compliance; no license grant in provided data, refer to official Apache 2.0 terms.

Apache 2.0 is an OSI-approved permissive license that generally allows commercial deployment and proprietary modifications. However, use for commercial short-video production should include: (1) review of model provider terms (Seedance, OpenAI, Anthropic, etc.) to ensure their outputs allow commercial redistribution, (2) confirmation that adaptation of source materials (novels, scripts) does not violate copyright, (3) audit of output licensing and downstream distribution rights. The license itself does not restrict commercial use, but dependencies and content licensing do.

Security considerations

Desktop Electron app with local storage; default login (admin/admin123) must be changed in production. No explicit mention of credential encryption, API key management, or secure model supplier configuration. Vector DB and project files stored locally without documented encryption. Supplier system allows arbitrary TypeScript execution in-app; code review and sandboxing not mentioned. External API calls to model providers transmit content over network; verify provider TLS/security posture independently. No documented vulnerability disclosure process.

Alternatives to consider

Runway ML / Synthesia

Cloud-first SaaS platforms for video generation with built-in collaboration, stricter quality controls, and managed compliance. Higher cost but lower operational burden for teams.

Descript / Adobe Firefly

Established video editing + generative tooling with strong documentation and enterprise support. Proprietary but tighter integration and more polished UX.

Open-source alternatives (e.g., Deforum, AnimateDiff, ControlNet local stacks)

Maximizes cost control and model customization; requires deeper ML/DevOps expertise. Toonflow bundles these workflows with UI and agent orchestration, trading flexibility for usability.

Toonflow-app FAQ

Can I use Toonflow to generate commercial short-form videos?
Apache 2.0 license permits it, but you must verify: (1) model provider TOS allows commercial use of generated video, (2) source material (novel/script) has proper adaptation rights, (3) final output can be legally republished on your platform. License alone does not grant these rights.
What happens if I want to switch from one video model to another mid-project?
Supplier system allows editing model provider TypeScript logic in settings without restart. Existing generated content remains; new assets will use the updated supplier. No documented way to re-render prior content with a new model.
Is there a server or hosted version?
Not mentioned in provided data. Toonflow is a desktop Electron app. No SaaS or self-hosted server option documented.
How are project files backed up or synced across machines?
Not documented. Desktop app stores projects locally. Manual file export or OS-level file sync (e.g., cloud drive) required for backup or multi-machine access.
