About ProxAI
ProxAI is a transparent reverse proxy designed to enforce hard hourly and daily spending caps per LLM API client. With a simple change of just one base_url and no SDK required, developers can seamlessly protect their budgets against runaway LLM costs.
The tool works out-of-the-box with major providers including OpenAI, Anthropic, Mistral, Groq, DeepSeek, and 5 others. If a client goes over its set cap, ProxAI immediately responds with a 429 status code before the upstream provider is ever called, ensuring that the worst-case scenario is your predefined cap rather than an unexpected credit card bill.
ProxAI is fully open-source (licensed under AGPL-3.0) and highly portable. It can be self-hosted as a single Go binary or a lightweight ~10 MB Docker image supporting both amd64 and arm64 architectures with zero telemetry. Alternatively, users can take advantage of the hosted beta version available at proxai.eu, which is free and requires no credit card.
Pros of ProxAI
- Enforces hard hourly and daily spending caps per LLM API client
- Requires only a single base_url change with no SDK needed
- Supports OpenAI, Anthropic, Mistral, Groq, DeepSeek, and 5 additional providers
- Blocks requests exceeding the cap (returning 429) before calling upstream
- Highly self-hostable as a single Go binary or lightweight ~10 MB Docker image with zero telemetry
Cons of ProxAI
- Hosted version is currently in beta
- Open-source license is AGPL-3.0, which may have specific compliance requirements for commercial adaptations
- Limited to the specific providers and features outlined in the current tool scope
Frequently Asked Questions
How does ProxAI enforce spending caps?
ProxAI acts as a transparent reverse proxy. When a client makes a request, it checks the hourly or daily spending limits. If the cap is exceeded, it immediately returns a 429 status code before the upstream API is ever called.
Do I need to install a special SDK to use ProxAI?
No SDK is required. You only need to change a single base_url in your existing configuration to route your requests through ProxAI.
Which LLM providers are supported?
ProxAI supports OpenAI, Anthropic, Mistral, Groq, DeepSeek, and 5 additional providers.
Can I self-host ProxAI?
Yes, ProxAI is fully self-hostable. It is available as a single Go binary or a lightweight ~10 MB Docker image (supporting amd64 and arm64) with zero telemetry, licensed under AGPL-3.0.
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.
