Hamster

Hamster is an AI-native product workspace that helps teams align on what to build before coding agents start executing. It replaces sprint planning, grooming, and story points with shared briefs that capture reasoning, constraints, and customer context — giving every agent the full picture it needs to deliver correctly. Built by the team behind Taskmaster (1.5M+ downloads, 25K+ GitHub stars), Hamster extends structured agent planning from individual developers to entire product teams.

• Briefs — Create a shared brief that captures the reasoning, constraints, and decisions behind every feature so agents and teammates always have full context.
• Plans — Hamster generates a structured, scoped task plan from your brief with acceptance criteria that any coding agent can execute without babysitting.
• Real-time collaboration — Multiple team members edit briefs simultaneously with live cursors and typing indicators, enabling fast alignment across product, design, and engineering.
• Team alignment voting — Built-in alignment popovers let teammates vote and respond so the whole team is on the same page before work begins.
• Two-way issue tracker sync — Connect GitHub, Linear, or Jira; Hamster reads tickets, writes the brief, and keeps your tracker current as tasks complete.
• Hamster CLI — Syncs briefs, tasks, and plans directly into your repo so coding agents like Claude Code, Cursor, Codex, and Gemini read full context from the filesystem.
• Blueprints & Strategies — Reusable templates and goal-setting tools help teams maintain consistent delivery patterns across projects.
• Works with any AI coding tool — Compatible with Claude Code, Codex, Gemini, Grok, Cursor, Copilot, Roo Code, Windsurf, Aider, Cline, Amp, and Taskmaster.
• Enterprise security — Third-party audited and pen-tested architecture with SSO, advanced security controls, and dedicated support for enterprise teams.
