About Heym
Heym is a source-available platform designed for building, executing, and managing agentic AI systems directly on your own infrastructure. It enables teams to construct complex multi-agent workflows visually while retaining full sovereignty over their models, data, and credentials.
With Heym, users can seamlessly connect external data sources and tools, integrate specialized coding agents such as Codex and OpenCode, and insert human-in-the-loop approval stages at critical operational junctions. This visual approach allows both technical and non-technical stakeholders to collaborate effectively when designing intelligent agent pipelines.
To maintain operational confidence, Heym features robust built-in observability tools. Users can inspect execution traces, monitor costs, analyze response latency, and run performance evaluations for every execution. Completed workflows can be deployed flexibly as web portals, standard APIs, or Model Context Protocol (MCP) tools.
Pros of Heym
- Source-available software that can be self-hosted on your own infrastructure
- Visual workflow builder for constructing multi-agent systems
- Built-in observability including traces, cost tracking, latency metrics, and evaluations
- Flexible deployment methods as portals, APIs, or MCP tools
- Supports human-in-the-loop approvals and integrations with coding agents like Codex and OpenCode
Cons of Heym
- Requires technical setup and maintenance for self-hosting on private infrastructure
- Fewer managed cloud convenience features compared to fully hosted SaaS alternatives

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.
