About gate.cat
gate.cat is an essential developer tool designed to protect your systems from irreversible mistakes made by AI coding agents. Even without malicious intent, giving an AI agent shell access combined with a single confident miscalculation can spell disaster for your codebase and infrastructure.
Operating as a deterministic, fail-closed veto, gate.cat inspects tool calls directly at the boundary. It intercepts and refuses high-risk, irreversible commands—such as rm -rf, DROP TABLE, or terraform destroy—before they are ever executed. Built for flexibility, it supports Claude Code hooks, gated shells, and OpenAI-API proxies.
Backed by extensive testing, the creators replayed over 826,644 real agent commands with zero misses, and they transparently publish their own bypass map. Best of all, gate.cat is completely free forever and open-source under the Apache 2.0 license.
Pros of gate.cat
- Blocks irreversible commands like rm -rf and DROP TABLE before execution
- Deterministic, fail-closed veto security model at the boundary
- Supports Claude Code hooks, gated shells, and OpenAI-API proxies
- Free forever and open-source under the Apache 2.0 license
Cons of gate.cat
- Focused specifically on blocking destructive commands rather than full agent orchestration
- Requires proper integration setup (hooks, proxies, or shells) to function
- Relies on boundary inspection which must cover all potential execution paths
Frequently Asked Questions
What does gate.cat do?
gate.cat acts as a deterministic, fail-closed veto that inspects tool calls at the boundary. It blocks irreversible commands—such as rm -rf, DROP TABLE, and terraform destroy—before an AI coding agent can execute them.
How is gate.cat integrated?
It can be integrated via a Claude Code hook, a gated shell, or an OpenAI-API proxy.
Is gate.cat free to use?
Yes, gate.cat is free forever and open-source under the Apache 2.0 license.
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.
