Overview
Hamster provides an AI-native workspace to help product and engineering teams coordinate the software development lifecycle. It centers on a Brief it, Plan it, Ship it workflow where teams create detailed Briefs in Hamster Studio that capture context and decisions; AI then generates a structured plan with tasks and acceptance criteria that AI agents execute to align outcomes with the team’s intent. Key components include Taskmaster for AI task management and Hamster Chat for collaboration, with two-way integrations to Jira, Linear, and GitHub. The goal is to keep human teams aligned on strategy while using AI to carry out the execution, ensuring software delivery matches the original plan.
