Modus, serverless framework for intelligent APIs powered by WebAssembly
Modus is an open-source, serverless framework for building APIs powered by WebAssembly. It simplifies integrating AI models, data, and business logic with sandboxed execution. We built Modus to put code back at the heart of development. You write a function. export function sayHello(name: string): string { return `Hello, ${name}!`; } Then, Modus: - extracts the metadata of your functions - compiles your code with optimizations based on the host environment - caches the compiled module in memory for fast retrieval - prepares an invocation plan for each function - extracts connections, models,…

In plain words
Modus is an open-source, serverless framework that builds APIs using WebAssembly. Developers write functions that Modus automatically compiles, optimizes, and deploys with sandboxed execution environments. It streamlines integrating AI models, data, and business logic into APIs by handling metadata extraction, module caching, and endpoint generation. The framework targets developers who want to focus on writing code while Modus manages the infrastructure and compilation layers.

modus: a framework for building agentic flows powered by WebAssembly - hypermodeinc/modus
It simplifies the integration of models, context, and data. We're continuing to add additional capabilities to better support the construction and calling of tools. export function sayHello ( name : string ) : string { return `Hello, ${ name } !` ; } Then, Modus: Now you have a production ready scalable endpoint for your AI-enabled app. AI-ready when you’re ready. Launch and iterate. We believe that agentic flows are still fundamentally apps. As such, we've designed Modus primarily as a general-purpose framework, that just happens to treat models, agents, and tools as first-class components. Modus is optimized for apps that require sub-second response times. We’ve made trade-offs to…from github.com

I'm open-sourcing my game engine2023 · github.com · ▲318Modd.io is a collaborative game editor that runs in browser. It's kind of like Figma for game dev. We made this engine low-code and multiplayer-first, so developeres can quickly prototype casual multiplayer games. I hope some of you guys will find this useful. Would love to hear feedback also. Thank you. Engine Demo: https://www.modd.io
Talos – Open-source WASM interpreter for LeanJun 2026 · github.com · ▲106At Cajal (YC W26) we’re excited to share Talos (https://github.com/cajal-technologies/talos), an open source framework for formal verification of WebAssembly modules in Lean. AI is now writing tons of the code that gets pushed to production. As code generation gets cheaper, verification becomes the bottleneck. We believe in a future where every piece of software comes with a mathematical proof that it does what its author intended - in doing so, eliminating many classes of exploits. Talos is part of the foundation for that. Talos provides a Wasm interpreter optimized for…
