About HAR
HAR is an open-source, agent-agnostic framework designed specifically for orchestrating multi-agent coding workflows. Developed to help developers run a fleet of coding agents in parallel on any repository, HAR brings structure, control, and verifiable proof to automated software development.
As an open-source developer tool, HAR stands out by offering deterministic validation gates and full observability across every agent in operation. Because it is agent-agnostic and fully extensible, development teams can easily customize it to integrate smoothly into their unique tooling and workflows.

About WebMotion
WebMotion is a highly technical, open-source tool designed for browser-native video composition. It fundamentally shifts how programmatic video is created by eliminating the need for heavy server-side infrastructure like render farms, headless Chrome instances, or even FFmpeg. Instead, it leverages the DOM and the modern WebCodecs API to compose and encode MP4 videos directly within the user's browser. The core philosophy of WebMotion is deterministic rendering. Every single frame generated by the tool is a pure function of its frame index, meaning developers have absolute, frame-by-frame control over the output. This makes it an exceptionally powerful utility for developers and creators looking to programmatically generate data visualizations, generative art, or automated marketing videos using familiar web technologies (HTML/CSS/JS) entirely client-side.
Pros of WebMotion
- Operates entirely in the browser, eliminating server costs and the need for complex backend rendering infrastructure.
- Utilizes modern WebCodecs for fast, efficient, and native MP4 encoding.
- Completely open-source, allowing developers to inspect, modify, and host the tool themselves.
Cons of WebMotion
- Requires a solid understanding of web development and programmatic rendering, making it inaccessible to non-technical users.
- Performance and rendering speed are heavily reliant on the user's local machine and browser capabilities rather than scalable cloud servers.
Frequently Asked Questions
Do I need to install FFmpeg or run a backend server to use WebMotion?
No. WebMotion is entirely browser-native. It uses the WebCodecs API to encode video directly in the DOM, so there is no need for FFmpeg, headless Chrome, or a backend render farm.
What does it mean that 'every frame is a pure function of the frame index'?
It means the rendering is deterministic. You write code that defines exactly what a frame should look like based solely on its sequence number (e.g., Frame 1, Frame 2), ensuring perfect, predictable, and repeatable animations.
