Overview
Osloq is an AI-powered bug reproduction tool that connects to your GitHub repository, reads an issue, spins up a sandbox, clones your code, runs it, and attempts to reproduce the bug. It provides a detailed report with logs, screenshots, and the exact code path, so developers can jump straight to fixing the issue without manual reproduction.
Persona.js is a lightweight, open-source AI chat UI library that embeds into any website. It is framework-agnostic, backend-agnostic, and WebMCP-native, allowing your assistant to discover and execute tools exposed by the parent page. It supports streaming chat, voice, theming, and various layout modes (floating, docked, fullscreen).
