Async: AI-Powered Collaborative Coding Workflow

Async is an open-source developer tool that combines AI coding, task management, and code review into one streamlined workflow. Integrating Claude Code, Linear, and GitHub PRs, it automatically researches coding tasks, executes code changes in the cloud, and breaks work into reviewable subtasks, handling the entire workflow from GitHub issue to merged PR. Async excels with mature codebases, enforcing upfront planning, eliminating context switching, simplifying task tracking, and providing built-in code review. Built with FastAPI, Claude Code, and Google Cloud Platform, it supports desktop and mobile.
